Holdbrooke SJ, Afolabi BM, David NA, Kareem KO, Salako A, Aina OO. Perception, knowledge, and consumption pattern of dietary supplement used during COVID-19 pandemic among black Africans: Perspective of Nigerians. DIALOGUES IN HEALTH 2023; 2:100106. [PMID: 36744009 PMCID: PMC9889116 DOI: 10.1016/j.dialog.2023.100106] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/25/2022] [Revised: 01/23/2023] [Accepted: 01/28/2023] [Indexed: 02/04/2023]
Abstract
The awareness of the health implication of Covid-19 pandemic marked an increase consumption of various dietary and herbal supplements (DHS) for the deterrence and/or prophylaxis against the novel emerging and infectious disease. However, there is little indication of the usefulness or otherwise of their use in alleviating symptoms of COVID-19. Objectives To investigate the pattern and determinants of DHS use among the Nigerian population for the prevention and treatment of COVID-19. Design Cross-sectional questionnaire survey. Setting: Older adolescents and adults residing in Nigeria. Participants Participants (n = 645) residing in the Nigeria were recruited from different geo-political zones and various ethnic groups. Primary and secondary outcomes Prevalence and determinants for the use of different DHS for the prevention and treatment of COVID-19 in Nigeria, and sources of information for DHS use. Results Most participants (425, 65.9%) believed that dietary supplements are necessary during infectious disease outbreak, but a fewer proportion believed that supplements can be used in conjunction with other drugs to treat Covid-19. Vitamin C was the most known (70.0%) and Vitamin A. The least known (0.3%) dietary supplement Approximately half (50.2%) of the study subjects, more than a third (37.8%) and less than a quarter (22.7%) were aware that Folic acid, vitamin D and vitamin E are DS. Herbal dietary supplements mentioned as known by the study participants included Garlic (46.5%), Ginger (44.7%), Tumeric (36.3%), Moringa (40.0%) and Ginseng (26.3%). Citrus fruit as a DS was recognized by fewer (6.5%) study participants and only 1.6% referred to herbal tea as DHS. In all, 571 (88.5%) of the study participants took DHS during the Covid-19 pandemic with males 1.5 times more likely to take DHS than females (χ2 = 3.09, P-value = 0.08, OR = 1.54, 95% CI = 0.95, 2.47) during the pandemic. Participants reported lesser consumption of Selenium (27, 4.2%), Iron (20,3.1%), Zinc (61, 9.5%) and calcium (101, 15.7%) to prevent/treat Covid-19. Majority (271, 42.0%) of the study participants mentioned "health worker" as source of information on DHS while 13% mentioned "Social media". The sociodemographic determinants of DHS practices used to prevent/treat COVID-19 during the pandemic included older age group of 61-70 years, widows, secondary level of education and not employed. Conclusions The findings showed widespread use of DHS for the prevention and treatment of COVID-19. The use of DHS in this study was mainly guided by health workers with a marginal role of social media and Mass media. These findings call for a more robust consolidative tactic towards DHS to ensure its proper and safe use.

[PMID: 38187892 PMCID: PMC10764963 DOI: 10.3934/publichealth.2023058] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2023] [Revised: 10/16/2023] [Accepted: 10/29/2023] [Indexed: 01/09/2024] Open
Abstract
Background Fish oil (FO) dietary supplements (DS) have gained popularity over the past few decades and emerged as one of the most popular DS in both Europe and the USA. However, in Greece, no study has been carried out to determine the prevalence and characteristics of FO consumers. Objective The aim of this study was to describe the stance (i.e., beliefs, knowledge and habits) and practices of FO users in Greece towards DS. Methods A cross-sectional study, using in-person questionnaires and a stratified random sampling technique, was conducted throughout 2018-2019. A total of 28491 Greek citizens over 15 years old were interviewed in 74 regional units corresponding to the 13 administrative regions of Greece. Having used DS at least once, deemed one as: DS+FO, if FO were among them; DS-FO, if FO were never used or DS non-user, if DS were never used. Pearson's chi-square test was used to determine independence between relevant outcome variables and FO use and multinomial logistic regression was performed to create models predictive of FO use. Results The sample consisted of 3.5% DS+FO, 51.3% DS-FO and 43.8% DS non-users, while 1.4% could not remember whether they had used DS. Significant predictors for being a DS+FO were identified. DS+FO were more likely to judge a DS-less diet as insufficient, support DS use and comprehend DS's labels. Also, DS+FO had used additional DS, considered more parameters when buying DS and were receivers of DS recommendations from more sources compared to DS-FO. 90% of DS users seek at least one approval source of their DS and 50% support DS recommendation by doctors. Conclusion Favorableness towards DS is more prevalent among DS+FO. Most respondents lack knowledge about the legislative background of DS and many would agree to professional guidance.

Knowledge and Beliefs about Herb/Supplement Consumption and Herb/Supplement-Drug Interactions among the General Population, including Healthcare Professionals and Pharmacists: A Systematic Review and Guidelines for a Smart Decision System. Nutrients 2023; 15:nu15102298. [PMID: 37242184 DOI: 10.3390/nu15102298] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2023] [Revised: 05/03/2023] [Accepted: 05/11/2023] [Indexed: 05/28/2023] Open
Abstract
The increased consumption of a variety of herbs/supplements has been raising serious health concerns. Owing to an inadequate understanding of herb/supplement-drug interactions, the simultaneous consumption of these products may result in deleterious effects and, in extreme cases, even fatal outcomes. This systematic review is aimed at understanding the knowledge and beliefs about the consumption of herbs/supplements and herb/drug-supplement interactions (HDIs). The study follows the PRISMA guidelines. Four online databases (Web of Science; PubMed; Cochrane; and EBSCOhost) were searched, and a total of 44 studies were included, encompassing 16,929 participants. Herb and supplement consumption is explained mostly by the reported benefits across multiple conditions and ease of use. Regarding HDIs, most people take both herbs/supplements and prescription drugs simultaneously. Only a small percentage of participants have knowledge about their interaction effects, and many reported adverse interactions or side effects. Nevertheless, the main reason for stopping the prescribed drug intake is the perceived lack of its effect, and not due to interactions. Therefore, it is important to increase the knowledge about supplement use so that further strategies can be elaborated to better detect or be alert for whenever a potentially dangerous reaction and/or interaction may occur. This paper raises awareness regarding the need for developing a decision support system and ends with some considerations about the development of a technological solution capable of detecting HDIs and, thereby, aiding in the improvement of pharmacy services.

Abstract
Age acceleration (Age-A) is a useful tool that is able to predict a broad range of health outcomes. It is necessary to determine DNA methylation levels to estimate it, and it is known that Age-A is influenced by environmental, lifestyle, and vascular risk factors (VRF). The aim of this study is to estimate the contribution of these easily measurable factors to Age-A in patients with cerebrovascular disease (CVD), using different machine learning (ML) approximations, and try to find a more accessible model able to predict Age-A. We studied a CVD cohort of 952 patients with information about VRF, lifestyle habits, and target organ damage. We estimated Age-A using Hannum's epigenetic clock, and trained six different models to predict Age-A: a conventional linear regression model, four ML models (elastic net regression (EN), K-Nearest neighbors, random forest, and support vector machine models), and one deep learning approximation (multilayer perceptron (MLP) model). The best-performing models were EN and MLP; although, the predictive capability was modest (R2 0.358 and 0.378, respectively). In conclusion, our results support the influence of these factors on Age-A; although, they were not enough to explain most of its variability.

Prevalence, Determinants, and Consumer Stance towards Dietary Supplements According to Sex in a Large Greek Sample: A Cross-Sectional Study. Nutrients 2022; 14:nu14235131. [PMID: 36501160 PMCID: PMC9739401 DOI: 10.3390/nu14235131] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2022] [Revised: 11/25/2022] [Accepted: 11/27/2022] [Indexed: 12/03/2022] Open
Abstract
A stratified random sampling technique was used in order to explore the prevalence of and the factors influencing dietary supplement (DS) use and the consumer stance towards DS by Greeks (n = 28,491, ≥15 years) according to sex. Additionally, we performed a Pearson’s chi-square to test within DS users for the dependence between sex and the examined factors, and binary logistic regression to create predictive DS user profiles. A history of DS use accounted for 55.5% and was more prevalent in women (58.4% vs. 52.3%, p < 0.001); multivitamins were the most popular DS used. The significant predictors for DS use for both sexes were age, education, employment status, exercise, and following a special diet, while BMI and monthly income were significant for women and men, respectively. The women and men DS users had mostly illness-health and fitness-related goals, respectively. Substantial proportions of the respondents had false beliefs about DS. A noticeable percentage of DS users displayed imprudent behavior regarding DS use, e.g., one out of five did not know the definition or did not take into consideration the recommended daily allowance. While several factors seemed to impact DS use, with certain differences between the sexes, the considerable lack of knowledgeable and responsible use of DS, with few differences between the sexes, observed can point state authorities and health professionals towards appropriate countermeasures.

Dietary Supplement Use in Relation to Socio-Demographic and Lifestyle Factors, including Adherence to Mediterranean-Style Diet in University Students. Nutrients 2022; 14:nu14132745. [PMID: 35807925 PMCID: PMC9269239 DOI: 10.3390/nu14132745] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2022] [Revised: 06/29/2022] [Accepted: 06/30/2022] [Indexed: 02/04/2023] Open
Abstract
The study aimed to examine socio-demographic and lifestyle determinants, including diet quality, of dietary supplement (DS) use among 2545 students who attended public universities in Warsaw. The data was collected using a self-administered health and lifestyle questionnaire and a 5-day dietary record method. Diet quality was assessed using a Mediterranean Diet Score. To determine the covariates of DS use, multivariate-adjusted logistic regression models with an estimation of odds ratios (ORs) and 95% confidence intervals (95% CIs) were used. The results showed that 41% of participants were DS users. The following predictors of DS use were identified: gender (male vs. female; OR:0.62, 95% CI:0.50–0.79), physical activity (high vs. low; OR:1.79, 95% CI:1.45–2.20), BMI (≥25 vs. 18.5–24.9 kg/m2; OR:0.77, 95% CI:0.61–0.98), cigarette smoking (yes vs. no; OR:0.67, 95% CI:0.52–0.86), and presence of chronic diseases (yes vs. no; OR:2.37, 95% CI:1.89–2.98). Moreover, higher nutritional knowledge, special diet usage, eating more meals/day, and fortified food consumption were determinants of DS use. Adherence to the Mediterranean-style diet was positively associated with DS use, a 1-score increment was associated with a 10% (p-trend = 0.011) higher probability of DS usage. Given that the use of vitamins and/or minerals is common among university students and their users are characterized by eating a higher quality diet, investigating the contribution of DS in overall dietary nutrient intake warrants further study.

Abstract
Dietary supplements (DS) are used by about 30-50% of adults in developed countries. However, only a few studies have compared the characteristics of DS users in different nations. This study aimed to identify and compare selected health-related behaviors of DS users from three European countries. A total of 3,588 adults (32.08 ± 8.04 years) from Poland (1,030 females, 287 males), Germany (994 females, 190 males), and the United Kingdom (911 females, 176 males) were included in the analysis. The study was based on a self-administered survey consisting of 70 questions regarding baseline characteristics, lifestyle, eating, and health habits. The associations of the obtained results were compared using the Kruskal-Wallis test, Pearson Chi-Square test, and Cramer's V value. The highest percentage of DS users (56.98%, n = 2,044) had a correct body weight, while higher body weight values were observed in 39.19% (n = 1,406). In terms of lifestyle, statistically significant differences (p < 0.05) were noted for alcohol consumption and the level of physical activity. Fruit and vegetables were most often consumed a few times a weeks (34.67%, n = 1,244). A similar result was observed for the consumption of whole grain (37.76%, n = 1,355), dairy (39.99%, n = 1,435), eggs (49.67%, n = 1,782), and meat (51.45%, n = 1,846). Most DS users did not have a chronic disease (66.72%, n = 2,394). Among the other conditions, a frequent occurrence (a few times a weeks) of gastrointestinal problems (28.29%, n = 1,015) and concentration disorders (29.15%, n = 1,046) was noted. Cramer's V values (<0.3) indicated a weak (but significant p < 0.05) relationship between the country of residence and most of the analyzed variables. In conclusion, DS users were characterized by a healthy lifestyle with appropriate behaviors but not healthy eating habits.

Abstract
Purpose This cross-sectional study aimed to provide estimates of dietary supplements (DS) use and to examine the relationship between sports dietary supplements (SDS) use and sociodemographic and lifestyle characteristic, body mass index and total daily physical activity (PA) in the adult population of Brasília, Brazil. Methods DS use was collected from 506 adults via a Food Frequency Questionnaire. DS were divided into multivitamin-minerals, electrolyte drinks, energy, protein, partial meal replacements, creatine, caffeine, and others. Electrolyte drinks, energy, and protein supplements were considered as SDS. PA was estimated from a 24-h PA recall, and total MET (metabolic equivalents)/day and MET-h/day were calculated. Participants were categorized as physically inactive or active according to MET-h/day. Results DS were used by 68% of adults; multivitamin-minerals (38%) and protein supplements (29%) were the most commonly used products. SDS use was associated with the highest socioeconomic level, younger age, and male gender, but not with PA. Also, most SDS users were physically inactive. Conclusion These findings indicate that SDS may be used unnecessarily by adults in Brasília. Specific recommendations and control procedures for the use of SDS are warranted.

[DOI: 10.3233/mnm-210562] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/13/2022]
Abstract
BACKGROUND: Social isolation required by the pandemic has led to some changes in individuals’ eating and lifestyle habits. OBJECTIVE: This study aimed to examine the change in nutrition and lifestyle habits of Turkish people during the COVID-19 outbreak and investigate the effects of individuals’ attitudes to healthy eating on this change. METHOD: At the beginning of the pandemic, individuals over the age of 18 participated in this cross-sectional study using an online questionnaire. Demographic information (age, gender, education level, place of residence and occupation), anthropometric data (reported weight and height); nutritional behavior information (number of meals per day, changes in consumption of various foods, use of nutritional supplements, etc.) and changes in lifestyle habits were requested from the participations. In addition, the Healthy Nutrition Attitude Scale (ASHN) was used to determine the healthy eating attitudes of the participants. RESULTS: A total of 432 volunteers participated in the study. It was revealed that body weight increased in 38.0% of the participants and activity level decreased in 73.1% of them during the initial stage of the pandemic. Nevertheless, 44.7% of participants reported increased sleep time, 77.8% reported increased social media use, and 66.7% reported increased stress and anxiety. It was found that the most commonly used nutritional supplements during this period were vitamin C, vitamin D and multivitamin complex. Women have significantly higher ASHN scores compared to men (p < 0.001). The total ASHN scores of those whose body weight did not change and those who increased their activity level were found to be significantly higher. It was determined that as the age and education level increased, the healthy eating attitude increased. CONCLUSION: In this study, findings regarding the negative effects of the COVID-19 quarantine on the nutrition and lifestyle of the Turkish people are presented. However, those with a positive attitude toward healthy eating were observed to have better weight control and eating habits and stress management during the pandemic. Therefore, it is thought that the dissemination of healthy eating attitudes in society may contribute to the maintenance of physical and mental health in the event of a pandemic.

[PMID: 34578852 PMCID: PMC8469530 DOI: 10.3390/nu13092968] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2021] [Revised: 08/24/2021] [Accepted: 08/24/2021] [Indexed: 11/16/2022] Open
Abstract
Dietary supplements are commercially available manufactured products used as an addition to the normal diet and involve vitamins, minerals, herbs (botanicals), amino acids, and various other products. With the use of a cross-sectional survey, the present paper intended to analyze dietary supplement usage and its health and sociodemographic determinants among attendants of primary health care centers in Abha City, southwestern Saudi Arabia. The sample was selected randomly using the two-stage cluster sampling technique. The study included 438 participants (115 males and 323 females). Their ages ranged from 18 to 59 years, with an average of 36.2 ± 11.7 years. The study showed that 330 people used dietary supplementation, giving a prevalence of 75.3% (95% CI: 71.1-79.2%). The most commonly used supplements were multivitamins (215, 65.2%), specific vitamins (60, 18.2%), and mineral pills (38, 11.5%). Advice from health care workers was the most frequent reason for using dietary supplements (49.4%). The majority (71.2%) reported feeling a better quality of life after using dietary supplements. The most frequent disadvantages of using dietary supplements were constipation and headache (30%) and the most frequent advantage was increasing appetite (59.8%). The people who most frequently recommended the use of supplements were health care workers (190, 57.6%), followed by friends or family members (62, 18.8%), and people on social media (43, 13%). Females had a significantly higher probability of using dietary supplements than males did (Cor = 2.0, 95% CI = 1.21-3.27), and those with a chronic disease had a considerably higher likelihood of using dietary supplements (cOR = 3.48, 95% CI = 2.04-6.06). Age, educational level, and marital status were not significantly related with dietary supplement usage. In conclusion, health care workers should focus on females and persons with chronic diseases in their practice. They should provide them with evidence-based advice regarding the use of dietary supplements. Continued medical education training programs tailored to the needs of health care staff addressing this issue should be provided. New guidelines should be developed to help health professionals to provide their patients with comprehensive care at the primary health care level.

Mohd Ashri MH, Abu Saad H, Adznam SNΆ. Socio-Demographic Characteristics, Body Weight Status and Energy Intake among Users and Non-Users of Dietary Supplements among Government Employees in Putrajaya, Malaysia. Nutrients 2021; 13:2248. [PMID: 34210072 PMCID: PMC8308269 DOI: 10.3390/nu13072248] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2021] [Revised: 06/22/2021] [Accepted: 06/28/2021] [Indexed: 12/28/2022] Open
Abstract
The use of dietary supplements is prevalent among many groups worldwide. However, few studies have examined their use among government employees. The aim of this cross-sectional study was to determine the association among sociodemographic characteristics, body weight status, and energy intake with dietary supplement use among government employees in Putrajaya, Malaysia. Simple random sampling was used to select a sample of 460 government employees from six ministries in Putrajaya, Malaysia. The data used in this study were collected through anthropometric measurements (height, weight, % body fat, waist and hip circumferences), a self-administered questionnaire (sociodemographic characteristics and dietary supplements use), and an interviewer-administered questionnaire (24-hour dietary recall; fruit and vegetable intake). The results indicated that the prevalence of dietary supplement use was 55.4%, with vitamin C (38.4%) being the most popular type of dietary supplement. Health issues (80.8%) were the most common reason for usage, internet (59.2%) was the main source of information, and pharmacies (71.8%) were the most indicated places to purchase dietary supplements. A multivariate analysis showed that participants who were female, married, had better monthly income, lived within a smaller household size, had a normal body mass index, classified as having unhealthily high body fat percentage, did not skip breakfast, and consumed at least five servings of fruits and vegetables per day were significantly more likely to use dietary supplements. In conclusion, health-conscious groups were more prone to consume dietary supplements, and due to the high prevalence of dietary supplement use, dissemination of accurate scientific information regarding dietary supplements is highly recommended among government employees.

Abstract
Background: consumers of dietary supplements (DS) or vitamin-mineral supplements (VMS) have a better health profile than nonconsumers; whether this also applies to healthier dietary patterns has seldom been assessed. We aimed to assess the dietary intake of subjects according to their consumption of DS or VMS. Methods: Cross-sectional, population-based studies conducted in 2009-2012 (3773 participants, 52.4% women, 57.0 ± 10.0 years) and 2014-2017 (2536 participants, 52.4% women, 60.0 ± 10 years) in Lausanne, Switzerland. Dietary intake was assessed via a 97-item food frequency questionnaire. Nutrients, consumption of specific food groups, dietary scores, and compliance with the Swiss nutritional guidelines were compared between VMS/DS consumers and nonconsumers. Results: In 2009-2012, after multivariable adjustment for gender, age, body mass index, education, smoking, country of birth, sedentariness, diet and total energy intake, VMS/DS consumers had a higher score for the "Fruits & vegetables"(-0.09 ± 0.02 vs. 0.15 ± 0.05) dietary pattern and a lower score for the "Fatty & sugary" dietary pattern (0.02 ± 0.02 vs. -0.14 ± 0.04) and had a lower likelihood to comply with the guideline on total fat [odds ratio and 95 %CI: 0.72 (0.57-0.89)] than nonconsumers. In 2014-2017, after multivariable adjustment, no differences (at p < 0.005) were found between VMS/DS consumers and nonconsumers. Conclusion: VMS/DS consumers tend to have healthier dietary choices than nonconsumers. The beneficial effect of VMS and/or DS consumption is decreased, as it does not target subjects who really need them.

Abstract
Food supplements (FS) are often consumed as one of the strategies to fight ageing-associated pathologies, especially in the case of oxidative stress-related diseases. Despite the popularity of FS, some concerns about their quality and safety have been raised, especially regarding the presence of contaminants. This paper reviews and discusses the occurrence of contaminants in marketed samples of FS in the last two decades, considering both scientific literature and notifications registered on RASFF portal. The most relevant classes of contaminants were included namely metals, toxins, pesticides, dioxins and PCBs, as well as pharmacologically active ingredients. Variable amounts of contaminants were reported in a significant number of commercially available FS. Although the presence of contaminants does not necessarily mean that their levels exceed the regulatory limits or that the FS intake constitutes a risk to human health, it alerts for the need to further monitor FS safety. The evaluation of the risk associated to the consumption of FS, especially in the elderly population, is particularly challenging due to the frequent exposure to multiple toxicants and to different exposure sources, as well as due to possible pre-existing diseases and respective therapeutics. Therefore, improved quality control procedures and monitoring programs should be pursued in order to avoid undesirable products and assure the safety of FS.

Abstract
The use of dietary supplements (DS) is increasing worldwide, however, there are limited studies examining the characteristics of people who take supplements in the United Arab Emirates. To examine the use of DS and their association with sociodemographic/lifestyle factors among college students in the UAE. A cross-sectional study conducted on 452 (18 to 24 years) college students (247 females and 205 males). A self-administered questionnaire that included sociodemographic and lifestyle characteristics, DS use, attitudes, and behavior was used. The prevalence of DS users was 35.6%. Dietary supplement use was significantly more among males than females (P = 0.008). The males preferred protein supplements (29.4%), while females consumed multivitamin and mineral supplements. Dietary supplement use was related to physical activity and the existence of a health problem. Males took DS for medical needs and to increase their muscle mass while females took them for medical needs (P = 0.001). While there a was significant difference between DS users and non-users related to knowledge (P = 0.000). The majority of DS users agreed that supplements are essential for health (68.3%) and only 39.8% agreed it was safe to use. Dietary supplement users source of information was health care providers (30.5%) followed by social media (22.2%). The prevalence of supplement use among college students was moderate among college students in the UAE. The results draw the attention for increasing public awareness about the DS appropriate use and safety from reliable sources so they could make more informed choices.

Abstract
“Nutrition” and “Pharmaceutical” together build up the perception of “Nutraceuticals” that
refer to the food or dietary supplements that help to incorporate additional health benefits to the fundamental
sustenance accomplished on daily basis. Each nutraceutical contains one or more bioactive
molecules that are usually obtained by chemical and/ or biotechnological synthesis or by extraction
from natural sources. Among the natural sources, marine bionetwork possess immense potential for
the presence of bioactive compounds. Some of these bioactive compounds as isolated from marine
sources, have potential use as nutraceuticals. This mini review provides a brief overview of nutraceutical
compounds from marine sources that are currently under research and/or have been commercialized.
A detailed discussion on the biochemical categories of compounds and the marine organisms that
play as potential sources of these bioactive nutraceutical compounds have been included.

Abstract
BACKGROUND Flavonoids exert anti-inflammatory properties and modulate oxidative stress in vitro, suggesting a protective effect on lung function, but epidemiological studies examining this association are scarce. METHODS A stratified random sample was drawn from the GA²LEN screening survey, in which 55,000 adults aged 15 to 75 answered a questionnaire on respiratory symptoms. Post-bronchodilator spirometry was obtained from 2850 subjects. Forced vital capacity (FVC), the ratio between the forced exhaled volume in 1 second (FEV₁) and FVC (FEV₁/FVC), FVC below lower limit of normal (FVC < LLN), and FEV₁/FVC < LLN were calculated. Intake of the six main subclasses of flavonoids was estimated using the GA²LEN Food Frequency Questionnaire. Adjusted associations between outcomes and each subclass of flavonoids were examined with multivariate regressions. Simes' procedure was used to test for multiple comparisons. RESULTS A total of 2599 subjects had valid lung function and dietary data. A lower prevalence of FVC < LLN (airway restriction) was observed in those with higher total flavonoid (adjusted odds ratio (aOR), higher vs. lowest quintile intake 0.58; 95% Confidence Interval (CI) 0.36, 0.94), and pro-anthocyanidin intakes (aOR 0.47; 95% CI 0.27, 0.81). A higher FEV₁/FVC was associated with higher intakes of total flavonoids and pro-anthocyanidins (adjusted correlation coefficient (a β-coeff 0.33; 0.10, 0.57 and a β-coeff 0.44; 95% CI 0.19, 0.69, respectively). After Simes' procedure, the statistical significance of each of these associations was attenuated but remained below 0.05, with the exception of total flavonoids and airway restriction. CONCLUSIONS This population-based study in European adults provides cross-sectional evidence of a positive association of total flavonoid intake and pro-anthocyanidins and ventilatory function, and a negative association with spirometric restriction in European adults.

Abstract
Background Food supplements, and in particular those containing botanicals (plant food supplements, PFS), have in recent decades been of great interest both to consumers and to food/pharmaceutical industries. Objectives The aim of this paper is to examine replies by Italian consumers to the PlantLIBRA consumers' survey in order to: 1) assess the behaviour of an Italian population with respect to the use of PFS, and to compare it with that of other 5 countries involved in the whole survey; 2) identify different habits in the 4 Italian cities selected according to their geographical distribution; 3) collect independent information on the actual intake of PFS and consumers' behaviour. Subjects/setting 397 Italian consumers enrolled, 187 males (49.5%) and 191 female (50.5%). The distribution of subjects among the 4 cities included was: Milan 99; Venice 90; Rome 96 and Catania 96. Results The interest in PFS in Italy is high, the prevalence of "regular" consumers being 22.7%. Some differences were observed between the 4 cities involved: the pattern of use during the year was specific to each city; consumers in Milan reported reasons to use PFS significantly different from those in the whole Italian sample and did not indicate supermarkets as an important place of purchase; respondents from Rome and Catania more frequently used family doctors and pharmacists as a source of recommendation. Some significant difference among cities, sex and age groups were observed when the most frequently used botanicals were ranked. Conclusions The results provide new insights on the socio-economic characteristics and lifestyle of Italian PFS consumers, on their reasons for and pattern of use, and on their behaviour and expectations. The value of this information is not restricted to the specific country (Italy) but allows for a more general evaluation of the pattern of use, according to habits and geographical area.

Abstract
Objectives: Few previous studies have assessed the effects of concomitant administration of multiple potentially psychoactive nutrients. Methods: 95 healthy adult participants consumed either a nutrient enriched breakfast bar (containing α-Linolenic acid, l-tyrosine, l-theanine, vitamins, minerals and 21.5 mg of caffeine) or an isocaloric, macronutrient matched control bar for 56 days. Cognitive function and mood were assessed pre-dose and at 40- and 160-min post-dose on the 1st and 56th day of the intervention period. Results: The results demonstrated acute effects of treatment across post-dose assessments on both assessment days in terms of alertness, and on tasks assessing attention, working and episodic memory and executive function, including cognitively demanding Serial subtraction and Rapid Visual Information Processing tasks. There were no evident chronic effects independent of the breakfast bars’ acute effects. Discussion: These results demonstrate that a nutrient enriched breakfast bar with low caffeine content can exert striking beneficial effects on acute cognitive function and alertness.

[PMID: 28904529 PMCID: PMC5590555 DOI: 10.1080/16546628.2017.1361769] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2016] [Revised: 06/06/2017] [Accepted: 07/18/2017] [Indexed: 11/03/2022] Open
Abstract
Background: The consumption of fruits, vegetables, and dietary supplements correlate. Most previous studies have aimed to identify the determinants of supplement uses or the distinct features of supplement users; this literature lacks a discussion on dietary supplement consumption as a predictor of fruit and vegetable consumption. Objective: This study examines how dietary supplement consumption correlates with fruit and vegetable consumption by combining scanner data and surveys of Korean household grocery shopping. Methods: Propensity score matching (PSM) is used to identify the relationship between dietary supplement consumption and fruit and vegetable consumption in a household. A logit regression using supplement consumption as the dependent variable is used. Then, the supplement takers (the treatment group) are matched with non-takers (the control group) based on the propensity scores estimated in the logit regression. The fruit and vegetable consumption levels of the groups are then compared. Results: We found that dietary supplement use is associated with higher fruit and vegetable consumption. This supports the health consciousness hypothesis based on attention bias, availability heuristics, the focusing effect, and the consumption episode effect. It rejects the health substitute hypothesis based on economic substitutes and mental accounting. Conclusions: Future research on the health benefits of dietary supplements should address the complementary consumption of fruits/vegetables and their health benefits to avoid misstating the health effects of supplements.

Abstract
OBJECTIVE To characterise German vitamin and mineral supplement users differentiated by their motives for supplement use. DESIGN Data were obtained from the German National Nutrition Monitoring (2010/11) via two 24 h dietary recalls and a telephone interview. Motive-based subgroups of supplement users were identified by factor and cluster analysis. Sociodemographic, lifestyle, health and dietary characteristics and supplement use were examined. Differences were analysed using χ 2 tests, logistic and linear regression models. SETTING Germany, nationwide. SUBJECTS Individuals (n 1589) aged 18-80 years. RESULTS Three motive-based subgroups were identified: a 'Prevention' subgroup (n 324), characterised by the motive to prevent nutrient deficiencies; a 'Prevention and additional benefits' subgroup (n 166), characterised by motives to prevent health problems and improve well-being and performance; and a 'Treatment' subgroup (n 136), characterised by motives to treat nutrient deficiencies or diseases. Members of the two prevention subgroups had a higher Healthy Eating Index score and tended to be more physically active than non-users. Those in the 'Prevention and additional benefits' subgroup supplemented with a greater number of micronutrients. Members of the 'Treatment' subgroup tended to be older and have a lower self-reported health status than non-users, and supplemented with a smaller number of micronutrients. CONCLUSIONS The majority of supplement users take supplements for preventive purposes and they are more health conscious than non-users of supplements due to their concerns about developing health problems. Those supplementing for treatment purposes may have underlying health indications and may be more likely to benefit from supplementation than those supplementing for preventive purposes.

Abstract
Wine by-products, in particular grape pomace, can be an important source of polyphenols and dietary fibers and are increasingly being used as a starting material in the industrial production of plant food supplements, such as other matrices containing biomolecules, with antioxidant properties. The risk associated with the consumption of these products was recently analyzed through a study of potential genotoxic and carcinogenic compounds that can be found in the marketed products. In particular, occurrence data about contamination with the mycotoxin ochratoxin A were also reported. This short review aims at giving an overview about the quality and benefits of these kinds of food supplements, and also about risks of incorrect use, focusing on the emerging need for stricter European regulations.

Abstract
Food fortification can deliver essential micronutrients to large population segments without modifications in consumption pattern, suggesting that fortified foods may be formulated for populations at risk for fragility fractures. This scoping review determined the extent to which randomized controlled studies have been carried out to test the impact of fortified foods on bone outcomes, searching PubMed for all studies using the terms 'fortified AND bone', and 'fortification AND bone'. Studies were restricted to English language, published between 1996 and June 2015. From 360 articles, 24 studies met the following criteria: human study in adults ⩾18 years (excluding pregnancy or lactation); original study of a fortified food over time, with specific bone outcomes measured pre- and post intervention. Six studies involved adults <50 years; 18 involved adults ⩾50 years. Singly or in combination, 17 studies included calcium and 16 included vitamin D. There were 1 or 2 studies involving either vitamin K, magnesium, iron, zinc, B-vitamins, inulin or isoflavones. For adults <50 years, the four studies involving calcium or vitamin D showed a beneficial effect on bone remodeling. For adults ⩾50 years, n=14 provided calcium and/or vitamin D, and there was a significant bone turnover reduction. No consistent effects were reported in studies in which addition of vitamin K, folic acid or isoflavone was assessed. Results from this scoping review indicate that up to now most studies of fortification with bone health have evaluated calcium and/or vitamin D and that these nutrients show beneficial effects on bone remodeling.

Vitamin-Mineral Supplement Use Patterns in Elderly Koreans: Data from the 2007-2008 Korean National Health and Nutrition Examination Survey. Korean J Fam Med 2016; 37:123-9. [PMID: 27073612 PMCID: PMC4826992 DOI: 10.4082/kjfm.2016.37.2.123] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2015] [Revised: 08/26/2015] [Accepted: 09/24/2015] [Indexed: 12/17/2022] Open
Abstract
Background Vitamin-mineral supplements are the most popular dietary supplements in Korea. However, few studies have assessed the relationship between vitamin-mineral supplementation and associated factors among the Korean elderly. The purpose of this study was to assess the use of vitamin-mineral supplements among elderly in Korea as well as its association with sociodemographic factors, health-related behaviors, medical conditions, and nutrient intake. Methods This study was based on data from the Korean National Health and Nutrition Examination Survey, conducted by the Korean Ministry of Health and Welfare from 2008 to 2009. Data from 3,294 elderly men and women (65 years of age and older) were analyzed. Multivariable-weighted logistic regression model analysis was used to evaluate the association between vitamin-mineral supplement use and sociodemographic factors, health-related habits, and medical conditions. Results Vitamin-mineral supplementation was reported by 16.3% of the participants. The most common reason for using dietary supplements was recommendations from friends and acquaintances. Highly educated person, female participants had a greater likelihood of taking vitamin-mineral supplements. In addition, analysis of nutrient intake from food sources alone revealed a lower proportion of vitamin-mineral supplement users with nutrient intakes below the estimated average requirements for vitamin A, vitamin C, thiamine, riboflavin, niacin, calcium, iron, and phosphorus, compared to nonusers. However, vitamin-mineral supplementation was not associated with health-related behaviors or medical conditions. Conclusion Highly educated person, elderly Korean women had a greater likelihood of using vitamin-mineral supplements. In addition, nutrient intakes from food sources alone were significantly higher among vitamin-mineral supplement users. Finally, vitamin-mineral supplementation may be an indicator of healthier diet in elderly Koreans.

Abstract
Recent trends in functional foods and supplements have demonstrated that bioactive molecules play a major therapeutic role in human disease. Nutritionists and biomedical and food scientists are working together to discover new bioactive molecules that have increased potency and therapeutic benefits. Marine life constitutes almost 80% of the world biota with thousands of bioactive compounds and secondary metabolites derived from marine invertebrates such as tunicates, sponges, molluscs, bryozoans, sea slugs and many other marine organisms. These bioactive molecules and secondary metabolites possess antibiotic, antiparasitic, antiviral, anti-inflammatory, antifibrotic and anticancer activities. They are also inhibitors or activators of critical enzymes and transcription factors, competitors of transporters and sequestrants that modulate various physiological pathways. The current review summaries the widely available marine-based nutraceuticals and recent research carried out for the purposes of isolation, identification and characterization of marine-derived bioactive compounds with various therapeutic potentials.

Abstract
Grape pomaces are increasingly being used as starting material in the industrial production of plant food supplements (PFS), food coloring, and tartrates, but they are at risk of ochratoxin A (OTA) contamination, a mycotoxin with nephrotoxic and carcinogenic effects. We analyzed 24 commercial PFS and 13 food coloring samples derived from Vitis vinifera, mainly pomaces, using a HPLC-FLD method for OTA determination. OTA was found in 75% of PFS samples and 69% of food coloring samples at levels of <1.16-20.23 μg/kg and <1.16-32.00 μg/kg, respectively. The four commercial leavening agents containing tartrates were found to be negative for OTA. All eight samples collected in two distilleries that use grape pomaces and wine lees to produce tartrates and other byproducts contained OTA at levels of <1.16-240.93 μg/kg. The high incidence of OTA contamination in PFS and food coloring agents derived from V. vinifera suggests that maximum permitted level(s) should be established for this mycotoxin in these products.

Abstract
Background The popularity of botanical products is on the rise in Europe, with consumers using them to complement their diets or to maintain health, and products are taken in many different forms (e.g. teas, juices, herbal medicinal products, plant food supplements (PFS)). However there is a scarcity of data on the usage of such products at European level. Objective To provide an overview of the characteristics and usage patterns of PFS consumers in six European countries. Design Data on PFS usage were collected in a cross-sectional, retrospective survey of PFS consumers using a bespoke frequency of PFS usage questionnaire. Subjects/setting A total sample of 2359 adult PFS consumers from Finland, Germany, Italy, Romania, Spain and the United Kingdom. Data analyses Descriptive analyses were conducted, with all data stratified by gender, age, and country. Absolute frequencies, percentages and 95% confidence intervals are reported. Results Overall, an estimated 18.8% of screened survey respondents used at least one PFS. Characteristics of PFS consumers included being older, well-educated, never having smoked and self-reporting health status as “good or very good”. Across countries, 491 different botanicals were identified in the PFS products used, with Ginkgo biloba (Ginkgo), Oenothera biennis (Evening primrose) and Cynara scolymus (Artichoke) being most frequently reported; the most popular dose forms were capsules and pills/tablets. Most consumers used one product and half of all users took single-botanical products. Some results varied across countries. Conclusions The PlantLIBRA consumer survey is unique in reporting on usage patterns of PFS consumers in six European countries. The survey highlights the complexity of measuring the intake of such products, particularly at pan-European level. Incorporating measures of the intake of botanicals in national dietary surveys would provide much-needed data for comprehensive risk and benefit assessments at the European level.

Abstract
In the last decades nutraceuticals have entered the health market as an easy and attractive means of preventing diseases. These products are of interest for an increasingly health-concerned society and may be especially relevant for preventing or delaying a number of age-related diseases, i.e. arthritis, cancer, metabolic and cardiovascular diseases, osteoporosis, cataracts, brain disorders, etc. Nutraceuticals are marketed in a variety of forms, composition and potential applications which have made their definition ambiguous and their use uncontrolled and poorly funded. Although epidemiological, animal and in vitro studies have given evidence of the potential benefits of some of these nutraceuticals or of their components, definitive proof of their effects in appropriate human clinical trials is still lacking in most cases, more critically among people above 65 years of age. We cover the well-established nutraceuticals (polyvitamins, omega-3 fatty acids, etc.) and will focus on many other 'novel' commercial nutraceuticals where the scientific evidence is more limited (food extracts, polyphenols, carotenoids, etc.). Solid scientific evidence has been reported only for a few nutraceuticals, which have some health claims approved by the European Food Safety Authority (EFSA). Further well-designed trials are needed to improve the current knowledge on the health benefits of nutraceuticals in the elderly. Overall, there are some facts, a lot of fiction and many gaps in the knowledge of nutraceutical benefits.
