Homroy S, Chopra R, Singh PK, Dhiman A, Chand M, Talwar B. Role of encapsulation on the bioavailability of omega-3 fatty acids. Compr Rev Food Sci Food Saf 2024; 23:e13272. [PMID: 38284597 DOI: 10.1111/1541-4337.13272] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2023] [Revised: 10/21/2023] [Accepted: 10/29/2023] [Indexed: 01/30/2024]
Abstract
Omega-3 fatty acids (omega-3 FAs) have been widely recognized for their therapeutic advantages, including anti-inflammatory and cardioprotective properties. They have shown promise in enhancing regulatory function, promotingdevelopment and mitigating the progression of diabetes and cancer. The scientific communities, along with industries, are actively endorsing initiatives aimed at increasing the daily intake of lipids rich in omega-3 FAs. Nevertheless, incorporating polyunsaturated FAs (PUFAs) into food products poses several challenges due to their susceptibility to oxidation when exposed to oxygen, high temperatures, and moisture. This oxidative deterioration results in undesirable flavours and a loss of nutritional value. Various methods, including physical blending, interesterification, and encapsulation, have been utilized as ways to enhance the stability of edible oils rich in PUFA against oxidation. Encapsulation has emerged as a proven strategy for enhancing the oxidative stability and functional properties of omega-3 FA-rich oils. Multiple encapsulation methods have been developed to stabilize and improve the delivery of omega-3 FAs in food products. The selection of an appropriate encapsulation method depends on the desired application of the encapsulated oil. In addition, encapsulation enhances the bioavailability of omega-3 FAs by promoting increased absorption of the encapsulated form in the intestinal epithelium. This review discusses the techniques and principles of omega-3 FA-rich oil encapsulation and its role in improving stability and bioavailability. Furthermore, it also investigates the potential health benefits of these encapsulated oils. This review explores the variations in bioavailability based on encapsulation techniques and processing, offering vital insights for nutrition and product development.

Abstract
Background In 2013, there was an estimation of greater than 4.5 million Afghan refugees who had migrated to the least developed countries. Over one million are legally registered in Iran. We assessed the heart health status as described by the American Heart Association (AHA) in the Afghan refugee populace. Methods This cross-sectional survey was carried out on 1,634 Afghan refugees, including 746 males (45.7%) and 888 females (54.3%), selected through a convenience sampling method in 2016. The American Heart Association's seven cardiovascular health metrics were evaluated to specify the status of heart health in Afghan refugees. Differences with age and sex were analyzed using the χ2 test. Results Only one (0.1%) participant met the ideal for all seven cardiovascular health metrics. No significant differences were found between women and men in meeting the ideal criteria for more than five cardiovascular health metrics. As age increased, the proportion of refugees who met the ideal for more than five cardiovascular health metrics declined. Conclusions Refugees were not meeting the ideal cardiovascular health for some of the assessed metrics. Intervention to improve and monitor heart health in Afghan refugees is needed.

The Relationship between Macronutrient Distribution and Type 2 Diabetes in Asian Indians. Nutrients 2021; 13:nu13124406. [PMID: 34959958 PMCID: PMC8704419 DOI: 10.3390/nu13124406] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2021] [Revised: 12/06/2021] [Accepted: 12/07/2021] [Indexed: 01/06/2023] Open
Abstract
Asian Indians (AIs) are at increased risk for type 2 diabetes mellitus than other ethnic groups. AIs also have lower body mass index (BMI) values than other populations, so can benefit from strategies other than weight reduction. Macronutrient distributions are associated with improved glycemic control; however, no specific distribution is generally recommended. This study looks at whether a macronutrient distribution of 50:30:20 (percent of total calories from carbohydrates, fats, and protein) is related to diabetes status in AIs. Diet and Hemoglobin A1c (HbA1c) were assessed from convenience sample of AI adults in Maryland. A ratio of actual to needed calories using the 50:30:20 macronutrient distribution was then tested against diabetes status to identify associations. All groups except non-diabetic females, were in negative energy balance. The non-diabetic group consumed larger actual to needed ratios of protein than pre-diabetics and diabetics. However, all groups consumed protein at the lower end of the Acceptable Macronutrient Distribution Range (AMDR), and the quality of all macronutrients consumed was low. Therefore, weight loss may not be the recommendation for diabetes management for AIs. Increasing protein and insoluble fiber consumption, could play a critical role.

Abstract
BACKGROUND Gastrointestinal (GI) surgery involving gastric resection and bypass of intestinal segments was reported to facilitate glucose control in obese patients with type 2 diabetes (T2D). AIM Our aim was to assess whether the type of post-gastrectomy GI reconstruction also influences glucose control in T2D patients with BMI below 35 kg/m2 submitted to gastrointestinal surgery without bariatric intention. METHODS A cohort of T2D Caucasian patients (n = 40) with upper GI malignancy (n = 33) or complicated reflux disease (n = 7) were submitted to either a gastrectomy plus Billroth II (BII) gastrojejunal anastomosis (n = 17), a gastrectomy plus Roux-en-Y gastrojejunostomy (RY) reconstruction (n = 18; subtotal gastrectomy n = 7 and total gastrectomy n = 11), or atypical gastrectomy without reconstruction (no-R) (n = 5). Patients were evaluated before and 2 years after surgery for body weight, Hb1Ac, need of glucose lowering drugs, and presence of diabetes. RESULTS Body mass index (BMI) decreased after every surgical procedure when compared to baseline (- 0.9 ± 0.8 kg/m2 for BII vs - 4.3 ± 2.6 kg/m2 for RY vs - 4.6 ± 2.5 kg/m2 for no-R, p < 0.05), which was only significantly different after RY surgeries. Diabetes remission occurred in 5.9% of BII patients, in 27.8% of RY patients, and 0% of no-R patients, while in patients with persistent T2D, the needs for glucose-lowering drugs were significantly also decreased after RY (31.3% BII vs 66.7% RY vs 25% no-R, p = 0.03). CONCLUSIONS T2D Caucasian patients undergoing post-gastrectomy GI reconstructions without a bariatric intention experience a significant improvement of T2D, in a magnitude that could be influenced by the technical procedure performed in favor of RY reconstruction. Thus, presence of T2D should be taken into consideration when deciding for the type of post-gastrectomy GI reconstruction.

Abstract
The purpose of this literature review is to describe and assess the cultural barriers to behavior change in migrant South Asians, given the high morbidity and mortality associated with cardiovascular disease in this population. We reviewed studies that explored the relationship between South Asian culture in the Diaspora and lifestyle behaviors. Our review produced 91 studies, of which 25 discussed the relationship between various aspects of South Asians' belief system and their approach to modifying lifestyle habits. We identify 6 specific categories of beliefs which play the largest role in the difficulties South Asians describe with behavior change: gender roles, body image, physical activity misconceptions, cultural priorities, cultural identity, and explanatory model of disease. Future research and interventions should account for these cultural factors to successfully improve dietary habits and physical activity levels in migrant South Asian populations.

Abstract
It is estimated that type 2 diabetes (T2D) currently affects about 246 million people worldwide, with South Asians, especially Indians, having both the largest number of cases and the fastest growing prevalence. South Asian ethnicity has been identified as a major risk factor for the development of T2D with central adiposity, insulin resistance and an unfavourable lipid profile being identified as predominant signals of alarm. Leading databases, including Web of Science, Medline, PubMed and Science Direct, were consulted and manual searches were conducted for cited references in leading diabetes-related journals. In all, 152 articles were included for the final assessment reported in this review. Genetic predisposition, central adiposity and unfavourable lifestyle, including physical inactivity and an unhealthy diet, were associated with the prevalence of T2D in migrant South Asians. 'Westernization', acculturation, socio-economic factors and lack of knowledge about the disease have also been identified as contributors to the development of T2D in this population. Higher prevalence of T2D in migrant South Asians may not be entirely attributed to genetic predisposition; hence, ethnicity and associated modifiable risk factors need further investigation. Preventive measures and appropriate interventions are currently limited by the lack of ethnic-specific cut-off points for anthropometric and biological markers, as well as by the absence of reliable methods for dietary and physical activity assessment. This article describes the prevalence rate, risk factors and complications associated with T2D in migrant South Asians living in different countries.

Prediction of body-fat percentage from skinfold and bio-impedance measurements in Indian school children. Eur J Clin Nutr 2011; 65:1263-70. [PMID: 21731039 PMCID: PMC3242049 DOI: 10.1038/ejcn.2011.119] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2010] [Revised: 05/10/2011] [Accepted: 05/17/2011] [Indexed: 11/08/2022]
Abstract
BACKGROUND/OBJECTIVES Few equations for calculating body-fat percentage (BF%) from field methods have been developed in South-Asian children. The objective of this study was to assess agreement between BF% derived from primary reference methods and that from skinfold equations and bio-impedance analysis (BIA) in Indian children. SUBJECTS/METHODS We measured BF% in two groups of Indian children. In Pune, 570 rural children aged 6-8 years underwent dual-energy X-ray absorptiometry (DXA) scans. In Mysore (18)O in doubly labeled water was administered to 59 urban children aged 7-9 years. We conducted BIA at 50 kHz and anthropometry, including sub-scapular and triceps skinfold thicknesses. We used the published equations of Wickramasinghe, Shaikh, Slaughter and Dezenburg to calculate BF% from anthropometric data and the manufacturer's equation for BIA measurements. We assessed agreement with values derived from DXA and doubly labeled water using Bland-Altman analysis. RESULTS Children were light and thin on average compared with international standards. There was poor agreement between the reference BF% values and those from all equations. Assumptions for Bland-Altman analysis were not met for Wickramasinghe, Shaikh and Slaughter equations. The Dezenberg equations under-predicted BF% for most children (mean difference in Pune -13.4, LOA -22.7, -4.0 and in Mysore -7.9, LOA (-13.7 and -2.2). The mean bias for the BIA equation in Pune was +5.0% and in Mysore +1.95%, and the limits of agreement were wide; -5.0, 15.0 and -7.8, 11.7 respectively. CONCLUSIONS Currently available skinfold equations do not accurately predict BF% in Indian children. We recommend development of BIA equations in this population using a four-compartment model.

Abstract
Background The population in Norway has become multi-ethnic due to migration from Asia and Africa over the recent decades. The aim of the present study was to explore differences in the self-reported prevalence of cardiovascular disease (CVD) and associated risk factors by diabetes status in five ethnic minority groups compared to ethnic Norwegians. Methods Pooled data from three population-based cross-sectional studies conducted in Oslo between 2000 and 2002 was used. Of 54,473 invited individuals 24,749 (45.4%) participated. The participants self-reported health status, underwent a clinical examination and blood samples were drawn. A total of 17,854 individuals aged 30 to 61 years born in Norway, Sri-Lanka, Pakistan, Iran, Vietnam or Turkey were included in the study. Chi-square tests, one-way ANOVAs, ANCOVAs, multiple and logistic regression were used. Results Age- and gender-standardized prevalence of self-reported CVD varied between 5.8% and 8.2% for the ethnic minority groups, compared to 2.9% among ethnic Norwegians (p < 0.001). Prevalence of self-reported diabetes varied from 3.0% to 15.0% for the ethnic minority groups versus 1.8% for ethnic Norwegians (p < 0.001). Among individuals without diabetes, the CVD prevalence was 6.0% versus 2.6% for ethnic minorities and Norwegians, respectively (p < 0.001). Corresponding CVD prevalence rates among individuals with diabetes were 15.3% vs. 12.6% (p = 0.364). For individuals without diabetes, the odds ratio (OR) for CVD in the ethnic minority groups remained significantly higher (range 1.5-2.6) than ethnic Norwegians (p < 0.05), after adjustment for age, gender, education, employment, and body height, except for Turkish individuals. Regardless of diabetes status, obesity and physical inactivity were prevalent in the majority of ethnic minority groups, whereas systolic- and diastolic- blood pressures were higher in Norwegians. In nearly all ethnic groups, individuals with diabetes had higher triglycerides, waist-to-hip ratio (WHR), and body mass index compared to individuals without diabetes. Age, diabetes, hypertension, hypercholesterolemia, and WHR were significant predictors of CVD in both ethnic Norwegians and ethnic minorities, but significant ethnic differences were found for age, diabetes, and hypercholesterolemia. Conclusions Ethnic differences in the prevalence of CVD were prominent for individuals without diabetes. Primary CVD prevention including identification of undiagnosed diabetes should be prioritized for ethnic minorities without known diabetes.

Abstract
The role of nutrition is especially important in certain ‘lifestyle’ diseases that impact disproportionately on ethnic minority populations. The aim of this paper is to review the evidence of risk, health outcomes and interventions for certain diseases that affect the UK's largest ethnic minority group (South Asians) in order to help professionals better address the needs of this diverse population. Research evidence is presented on factors influencing access to services by ethnic minority populations and the changing UK policy background for public health and preventive care. The available research base on obesity, diabetes and CVD is discussed. Conditions such as type 2 diabetes, which are more prevalent among the South Asian population, are associated with poorer health outcomes and appear to exhibit links to diet and nutrition that start in childhood or even before birth; all making preventive care important. Obesity is a major risk factor and it appears that BMI thresholds may need to be lower for South Asians. Targeted interventions to improve diet and outcomes in the South Asian population also appear promising. Recent moves to promote access to evidence of ethnicity and health and to improve the cultural competence of organisations are discussed. Health professionals will increasingly need to promote lifestyle changes in a manner that meets the needs of a diverse population in order to address future public health challenges. Nutritionists and other professionals will need to ensure that interventions are culturally appropriate and involve engagement with extended family members and communities.

Abstract
AbstractObjectiveThe present qualitative study explored health perceptions, diet and the social construction of obesity and how this relates to the initiation and maintenance of a healthier diet in UK Pakistani women.DesignPakistani women in Greater Manchester participated in focus group and one-to-one discussions. Semi-structured interviews employing fictional vignettes and body shape images were used to explore the participants’ beliefs and practices regarding diet, overweight/obesity and the risk of type 2 diabetes. Transcripts were analysed using phenomenological and sociological approaches.SettingInterviews took place either in local community and Pakistani resource centres or in private homes.SubjectsFirst- and second-generation women who were both active in the community and housebound. The women spoke English and/or Urdu.ResultsThe fifty-five participants lacked the motivation to address weight gain and were unsure how to do so. There was a limited awareness of the link between weight gain and type 2 diabetes. Other barriers included the influence of Islam, culture and familial expectations on home cooking, perceptions that weight gain is inevitable (owing to ageing, childbirth or divine predestination) and the prioritisation of family concerns over individual lifestyle changes. As the findings of the present research did not correspond to existing educational and behaviour change models, a new Health Action Transition conceptual model is proposed.ConclusionsHealth education programmes that aim to address obesity and its associated risks in the South Asian community must take into account the complex beliefs and practices and the multiple dimensions of religion, ethnic and social identity within this population. The present study provides further insight into these factors and proposes a novel model for use in designing and implementing education interventions for British Pakistani women.

Abstract
This review discusses the prevalence of metabolic syndrome and cardiovascular disease in the South Asian population, evaluates conventional and emerging risk factors, and reinforces the need for ethnic-specific redefinition of guidelines used to diagnose metabolic syndrome. We reviewed recent and past literature using Ovid Medline and PubMed databases. South Asians represent one of the largest and fastest growing ethnic groups in the world. With this growth, a dramatic rise in the rates of acute myocardial infarction and diabetes is being seen in this population. Potential etiologies for this phenomenon include dietary westernization, poor lifestyle measures, adverse body fat patterning, and genetics. While traditional risk factors for diabetes and cardiovascular disease should not be overlooked, early metabolic syndrome has now been shown in the South Asian pediatric population, suggesting that "metabolic programming" and perinatal influences may likely play a substantial role. Health care practitioners must be aware that current guidelines used to identify individuals with metabolic syndrome are underestimating South Asian individuals at risk. New ethnic-specific guidelines and prevention strategies are discussed in this review and should be applied by clinicians to their South Asian patients.
