Abstract
Gac, Momordica cochinchinensis (Lour.) Spreng. belongs to the Cucurbitaceae family. It is more considered as a super fruit. The demand for this plant is growing in countries where its reputation is high, including traditional countries of gac culture and countries fond of super fruits and food supplements. In these latter countries, the industrial strategy aims at producing high added value in food supplements or nutritional rich preparations. However, when marketing is not the driving force and claims have to be related to scientific data, the situation of gac is less "heavenly", mainly because its most remarkable properties are in the field of micronutrients. These latter components are indeed very important for health but their supplementation on healthy populations brings no significant advantage. This paper proposes to review aspects important for the nutritional reputation of this plant: where it comes from, how it is cultured to have an optimal nutritional composition, what is its composition and how it can impact health of consumers, in which products it is used and what are the regulations to use it in different markets. One important goal of this review is to give a critical and scientific approach to confirm data on this fruit, which has been promoted by marketing departments injecting so many wrong and unverified information. Missing data will be highlighted and potential positive applications are proposed all along the text.

Abstract
The use of food supplements or functional food has significantly increased in the past decades, especially to compensate both the modern lifestyle and the food shortages of the industrialized countries. Despite food supplements are habitually intended to correct nutritional deficiencies or to support specific physiological functions, they are often combined with common drug therapies to improve the patient's health and/or mitigate the symptoms of many chronic diseases such as cardiovascular diseases, cystic fibrosis, cancer, liver and gastrointestinal diseases. In recent years, increased attentions are given to the patient's diet, and the use of food supplements and functional food rich in vitamins and antioxidants plays a very important role in the treatment and prevention of neurodegenerative diseases such as Parkinson's disease (PD). Natural compounds, phytochemicals, vitamins, and minerals can prevent, delay, or alleviate the clinical symptoms of PD in contrast to some of the main physiopathological mechanisms involved in the development of the disease, like oxidative stress, free radical formation, and neuroinflammation. The purpose of this review is to collect scientific evidences which support the use of specific biomolecules and biogenic elements commonly found in food supplements or functional food to improve the clinical framework of patients with PD.

Dietary Manganese Exposure in the Adult Population in Germany-What Does it Mean in Relation to Health Risks? Mol Nutr Food Res 2019; 63:e1900065. [PMID: 31216097 DOI: 10.1002/mnfr.201900065] [Citation(s) in RCA: 21] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2019] [Revised: 04/29/2019] [Indexed: 11/10/2022]
Abstract
Manganese is both an essential nutrient and a potential neurotoxicant. Therefore, the question arises whether the dietary manganese intake in the German population is on the low or high side. Results from a pilot total diet study in Germany presented here reveal that the average dietary manganese intake in the general population in Germany aged 14-80 years is about 2.8 mg day-1 for a person of 70 kg body weight. This exposure level is within the intake range of 2-5 mg per person and day as recommended by the societies for nutrition in Germany, Austria, and Switzerland. No information on the dietary exposure of children in Germany can be provided so far. Although reliable information on health effects related to oral manganese exposure is limited, there is no indication from the literature that these dietary intake levels are associated with adverse health effects either by manganese deficiency or excess. However, there is limited evidence that manganese taken up as a highly bioavailable bolus, for example, uptake via drinking water or food supplements, could pose a potential risk to human health-particularly in certain subpopulations-when certain intake amounts, which are currently not well defined, are exceeded.

Abstract
The industrial production of chondroitin sulfate (CS) uses animal tissue sources as raw material derived from different terrestrial or marine species of animals. CS possesses a heterogeneous structure and physical-chemical profile in different species and tissues, responsible for the various and more specialized functions of these macromolecules. Moreover, mixes of different animal tissues and sources are possible, producing a CS final product having varied characteristics and not well identified profile, influencing oral absorption and activity. Finally, different extraction and purification processes may introduce further modifications of the CS structural characteristics and properties and may lead to extracts having a variable grade of purity, limited biological effects, presence of contaminants causing problems of safety and reproducibility along with not surely identified origin. These aspects pose a serious problem for the final consumers of the pharmaceutical or nutraceutical products mainly related to the traceability of CS and to the declaration of the real origin of the active ingredient and its content. In this review, specific, sensitive and validated analytical quality controls such as electrophoresis, eHPLC (enzymatic HPLC) and HPSEC (high-performance size-exclusion chromatography) able to assure CS quality and origin are illustrated and discussed.

Abstract
Data provided by the European Commission show that public expenditures for food supplements have been constantly increasing over the last decade. The aim of the present study was to analyze the major food supplements regulations in the European Union and in Bulgaria. Relevant publications were searched and found in MEDLINE/PubMed, Scopus Database, Web of Knowledge, and in Internet-based search with predefined keywords. Numerous authors support the opinion that there is a real risk that low quality products may be distributed in countries with poor production control. Bulgarian national legislation have 6 regulations with different legal force for provision of healthy and safe food supplements on the market. Currently, the European Community is concerned about food products, including FS, launched on the market because the citizens require reliable protection of their health. This concern provoked the European Parliament and the Council to undertake a number of legislative initiatives in the field of production and control of food products. It is necessary to set more precise quality and safety criteria in future strategies associated with those products.

Abstract
The determination of vitamins in various food matrices is necessary for monitoring the quality and safety indicators of food, including the control of the use of vitamins as food additives - food colorings and antioxidants. As well it is necessary to evaluate the level of consumption of vitamins by different age and sex categories of the population. The analysis of the regulatory and methodical basis in the field of determining the content of vitamins in food, including food supplements, has been held. It is shown that the sample preparation process plays an important role in the procedure of determination of vitamins. The modern problems of sample preparation of foods depending on their matrix are considered. The tasks to improve the methodological base, including the harmonization of interstate and national standards of the Russian Federation with international regulatory documents, are marked. It is emphasized that the most promising methods of vitamins' determination for further development are mass-spectrometry and capillary electrophoresis. The selected methods are characterized by high authenticity of the results. Mass-spectrometric detection is characterized by identification reliability. Capillary electrophoresis is characterized of simplicity of analysis.

Abstract
Food biogenic amines, in particular, histamine, are often responsible for various enteric and vascular dysfunctions. Several years ago, the oral administration of copper-containing diamine oxidase (DAO), also called histaminase, able to oxidatively deaminate biogenic amines, had been suggested as a food supplement to control food allergy and enteric dysfunctions. This report is aimed to generate a global image on the behavior of orally administrated DAO dosage forms in the intestinal tract. The catalytic stability of DAO from Lathyrus sativus seedlings in various simulated intestinal media with different pH and containing different association of cholic acids, pancreatic proteases, bicarbonate, lipids, or alcohol was investigated. Cholic acids and lipids protected the enzyme in the simulated intestinal fluids. However, they were not able to protect against the inhibitory effect of 24-36% (v/v) ethanol. These observations may be relevant for oral administration of enzymes as food supplements or therapeutic bioactive agents.

Abstract
INTRODUCTION In the last 10 years, nutraceuticals have grown in interest to researchers, industry, and consumers and are now familiar in the collective imagination as a tool for preventing the onset of a disease. Often nutraceuticals are confused with biologically active phytochemicals/botanicals which can have health benefits. This is a misunderstanding however as the term nutraceutical refers to a product that must have a beneficial effect on health proven by clinical testing. Areas covered: A search has been performed on both recent patents and the literature regarding nutraceuticals focusing on the beneficial and proven health effects on pathological conditions to give an overview of the state-of-the-art developments in this area. Patents and literature data addressing specific pathological conditions are discussed. Expert opinion: Nutraceuticals represent a challenge for the future of drug-based pharmacotherapy, and, at the same time, are a powerful tool for the prevention of chronic disease. They are not proposed as an alternative to drugs, but instead, can be helpful to complement a pharmacological therapy and prevent the onset of chronic diseases in subjects who do not qualify for conventional pharmacological treatment.

Abstract
Phytosterols are one of the bioactive components responsible for the beneficial effects of Serenoa repens in Benign Prostate Hyperplasia. The aim of this study was to verify the actual variability of the phytosterols content in supplements containing serenoa, in order to provide useful elements to check the effectiveness of these preparations. The amount of campesterol, stigmasterol and β-sitosterol were determined by gas-chromatography in commercial raw materials and supplements containing serenoa in association or not with other botanicals. The experimental data were used to calculate amounts of phytosterols for recommended daily dose. The overall results of this study show an extreme variability in the content and also in the amounts per daily dose of phytosterols of the examined supplements (both mono/multi components). These data confirm that the characterization of serenoa based supplements is insufficient to ensure comparable effects between different products.

Abstract
BACKGROUND Nowadays, chlorophycean microalgae have attained a broad-spectrum attention as a potential candidate for biomass and bioenergy production. Despite their appreciated benefits, one of major problems is their low biomass and lipid productivity. Here we investigated the heterotrophic culture in shake flasks and stirred tank bioreactor to improve the lipid and biomass production in a naturally isolated strain of Chlorella vulgaris. METHODS A naturally isolated C. vulgaris strain was cultivated in BG-11 medium in shake flask and bioreactor. Its biochemical composition and growth kinetic parameters were investigated. RESULTS The biomass productivity was improved (3.68 fold) under heterotrophic culture compared to basal autotrophic culture condition in shake flask experiment. The total lipid content increased to 44% of total Dry Cell Weight (DCW) during heterotrophic growth after 21 days. Moreover, a great Fatty Acid Methyl Esters (FAME) yield was observed under heterotrophic cultivation. Total biomass and lipid content of microalgae in bioreactor experiment increased to 4.95 and 2.18 g L-1 respectively, during 5 days of the experiment compared to its basic autotrophic culture. CONCLUSION The techno-economic aspects of exploiting C. vulgaris as a biodiesel feedstock werealso evaluated. The results imply that heterotrophic cultivation could compensate the low biomass productivity in microalgae for green energy production. Ever growing rates of established patents on application of various genetic and bioengineering-based methods have made it possible to achieve higher lipid contents with reduced total costs for microalgal biodiesel production as well.

Abstract
The Panel on Food Additives and Nutrient Sources added to Food (ANS) was asked to deliver a scientific opinion on the safety of monacolins in red yeast rice (RYR) and to provide advice on a dietary intake of monacolins that does not give rise to concerns about harmful effects to health. The Panel reviewed the scientific evidences available as well as the information provided by interested parties in response of a public 'Call for data' launched by EFSA. The Panel considered that monacolin K in lactone form is identical to lovastatin, the active ingredient of several medicinal products authorised for the treatment of hypercholesterolaemia in the EU. On the basis of the information available, the Panel concluded that intake of monacolins from RYR via food supplements, could lead to estimated exposure to monacolin K within the range of the therapeutic doses of lovastatin. The Panel considered that the available information on the adverse effects reported in humans were judged to be sufficient to conclude that monacolins from RYR when used as food supplements were of significant safety concern at the use level of 10 mg/day. The Panel further considered that individual cases of severe adverse reactions have been reported for monacolins from RYR at intake levels as low as 3 mg/day. The Panel concluded that exposure to monacolin K from RYR could lead to severe adverse effects on musculoskeletal system, including rhabdomyolysis, and on the liver. In the reported cases, the product contained other ingredients in addition to RYR. However, these reported effects in particular musculoskeletal effects, have both occurred after ingestion of monacolin K and lovastatin independently. On the basis of the information available and several uncertainties highlighted in this opinion, the Panel was unable to identify a dietary intake of monacolins from RYR that does not give rise to concerns about harmful effects to health, for the general population, and as appropriate, for vulnerable subgroups of the population.

Abstract
This Technical Report contains a description of the activities within the work programme of the EU-FORA Fellowship on the risk assessment of white willow in food. The bark of different varieties of willow has had a long history of medical use as a means to reduce fever and as a painkiller. Willow bark is also used in weight loss and sports performance food supplements. The labelling of these products usually does not mention any restrictions to the length of use. The recommended doses for foods differ, sometimes exceeding doses recommended for pharmaceuticals. A systematic literature review on adverse effects potentially resulting from oral exposure to white willow (Salix alba) was performed. The aim of the study was to assess the risk for humans when consuming white willow bark in food. The preliminary results show that despite the long history of use only very limited data on toxicity of white willow bark are available. However, anaphylactic reactions in people with a history of allergy to salicylates may occur. Some other adverse effects of salicylates are considered to be of low relevance for the long-time consumption of white willow bark, mainly due to relatively low concentrations of salicin and the presence of compounds with gastroprotective action. However, it seems that the content of heavy metals, mainly cadmium, should be further addressed in risk assessment of white willow bark in food.

Abstract
The present scientific opinion deals with the evaluation of the safety of di‐magnesium malate (DMM) proposed as a novel food ingredient and as a source of magnesium for use in foods for the general population, food supplements, total diet replacement for weight control and food for special medical purposes (FSMP), and with the bioavailability of magnesium from this source. Additional information was sought from the applicant during the assessment process. However, despite several requests, the applicant did not provide the additional data. Consequently, the Panel performed this assessment on the basis of the available data and concluded that there was insufficient scientific evidence of a difference between the proposed novel food ingredient named as DMM and magnesium malate already authorised as a source of magnesium included in Annex II to Directive 2002/46/EC. Accordingly, the Panel was unable to assess the safety of DMM as a novel food ingredient. The Panel concluded that based on the data provided it was not possible to assess the dissociation of DMM into magnesium and malic acid. The Panel further concluded that if DMM dissociates, magnesium would be available following ingestion of DMM and the availability would appear similar to values reported for other sources of magnesium already permitted. Finally, the Panel noted that the proposed use levels could result in exposures to magnesium greater than its upper level (UL) (250 mg/day) for food supplements and for food for special medical purposes.

Abstract
The EFSA Panel on Food Additives and Nutrient Sources added to Food (ANS) provides a scientific opinion on the safety and bioavailability of silver hydrosol as a source of silver added for nutritional purposes to food supplements. Silver hydrosol is a suspension comprised of a mixture of positively charged silver ions and silver metal particles in water. The study report submitted, being a gastric disappearance study performed in six individuals, did not provide information on the systemic absorption of silver as such, and was not able to provide information on the bioavailability of silver from silver hydrosol. If silver from silver hydrosol is systematically available a complete toxicological evaluation is needed for its assessment. The application dossier was limited to an acute toxicity study with silver hydrosol and references to toxicological studies performed with forms of silver (e.g. salts of silver) which were considered neither relevant nor adequate to the risk assessment of silver hydrosol. The Panel concluded that the submitted data are insufficient to characterise the silver hydrosol regarding its nano specific properties and to assess either the bioavailability of silver from the source or the safety of the silver hydrosol as a source of silver added for nutritional purposes to food supplements.

Abstract
The Panel on Food Additives and Nutrient Sources added to Food (ANS) was asked to deliver a scientific opinion on the safety of hydroxyanthracene derivatives and to provide advice on a daily intake that does not give rise to concerns about harmful effects to health. Hydroxyanthracene derivatives are a class of chemical substances naturally occurring in different botanical species and used in food to improve bowel function. The ANS Panel reviewed the available scientific data on a possible relationship between hydroxyanthracene derivatives exposure and genotoxic and carcinogenic effects. On the basis of the data currently available, the Panel noted that emodin, aloe-emodin and the structurally related substance danthron have shown evidence of in vitro genotoxicity. Aloe extracts have also been shown to be genotoxic in vitro possibly due to the presence of hydroxyanthracene derivatives in the extract. Furthermore, aloe-emodin was shown to be genotoxic in vivo and the whole-leaf aloe extract and the structural analogue danthron were shown to be carcinogenic. Epidemiological data suggested an increased risk for colorectal cancer associated with the general use of laxatives, several of which contain hydroxyanthracene derivatives. Considering the possible presence of aloe-emodin and emodin in extracts, the Panel concluded that hydroxyanthracene derivatives should be considered as genotoxic and carcinogenic unless there are specific data to the contrary, such as for rhein, and that there is a safety concern for extracts containing hydroxyanthracene derivatives although uncertainty persists. The Panel was unable to provide advice on a daily intake of hydroxyanthracene derivatives that does not give rise to concerns about harmful effects to health.

Abstract
Low-substituted hydroxypropyl cellulose (L-HPC) is a low-substituted poly(hydroxypropyl) ether of cellulose. L-HPC is proposed for use as a food additive in food supplements in solid form (tablet), with a maximum use level of 20,000 mg/kg and a typical use level of 10,000 mg/kg. Exposure estimates to L-HPC from its proposed use were calculated for both typical and maximum use levels. Due to the close chemical relationship between L-HPC and other celluloses recently re-evaluated by EFSA, the Panel decided to read-across the biological data already evaluated in the context of the re-evaluation programme. The Panel concluded that there was no safety concern from the proposed use and use levels of L-HPC.

Abstract
Following a request from the European Commission, the EFSA Panel on Dietetic Products, Nutrition and Allergies (NDA) was asked to provide a supplementary dietary exposure and safety assessment of synthetic l-ergothioneine for those groups of the population which had been excluded by the applicant in the original application, i.e. infants and young children (i.e. toddlers), pregnant and breastfeeding women. Thus, intake estimates were calculated for these population groups and the following maximum anticipated daily intakes of l-ergothioneine from the NF, in addition to the background diet, were calculated: 2.82 mg/kg body weight (bw) per day for infants, 3.39 mg/kg bw per day for toddlers and 1.31 mg/kg bw per day for adults including pregnant and breastfeeding women. The Panel considers that based on the overall toxicological data the no-observed-adverse-effect level (NOAEL) of 800 mg/kg bw per day as established in the original assessment also pertains to pregnant and breastfeeding women as well as to young children (i.e. toddlers) and infants. The corresponding margins of exposure (i.e. the ratio between the NOAEL and the maximum anticipated daily intakes) are 284 for infants, 236 for young children and 610 for pregnant and breastfeeding women. These margins of exposure are considered sufficient. The Panel concludes that the novel food, synthetic l-ergothioneine, is safe under the proposed uses and use levels for infants, young children (i.e. toddlers) and pregnant and breastfeeding women.

Abstract
Mounting evidence of the effects of endocrine-disrupting chemicals (EDCs) in humans has led to assaying a vast array of food items (processed or packaged) as possible sources of human exposure to estrogens. In this study, we investigated the current situation in this respect of different food supplements and beer brands. Eleven food supplements and 24 beer brands were obtained from Helsinki, Finland. Sample preparation was carried out by established methods while estrogenic activities were assessed by a yeast bioluminescent assay, using two recombinant yeast strains (Saccharomyces cerevisiae BMAEREluc/ERα and S. cerevisiae BMA64/luc). All the food supplements as well as 81% of the beer samples tested were found to be estrogenic, with estradiol equivalent concentrations of food supplements and beer brands ranging from 7.5 to 11.5 µg/ml and from below detection limits to 43.6 ng/ml, respectively. The estrogenic activities detected in beer samples were not dependent on the beer's alcoholic content, the country of production, or the size of the production brewery. The results of our study imply that both food supplements and beers can be a significant source of human exposure to estrogens. Therefore, further studies and regular surveillance are warranted.

Abstract
Due to potential health benefits and the general assumption that natural products are safe, there is an increasing trend in the general population - including pregnant women - to supplement their diet with flavonoid-based food supplements. In addition, preclinical studies aim to prevent developmental adverse effects induced by toxic substances, infections, maternal or genetic diseases of the unborn child by administration of flavonoids at doses far above those reached by normal diets. Because these substances do not undergo classical risk assessment processes, our aim was to review the available literature on the potential adverse effects of maternal diet supplementation with flavonoid-based products for the developing child. A systematic literature search was performed in three databases and screened following four exclusion criteria. Selected studies were classified into two groups: 1. Studies on the developmental toxicity of single flavonoids in vitro or in animals in vivo, and 2. Studies on the developmental toxicity of single flavonoids or on flavonoid-mixtures in humans. The data collected indicate that there is a concern for the safety of some flavonoids within realistic human exposure scenarios. This concern is accompanied by a tremendous lack of studies on safety of these compounds during development making definite safety decisions impossible. Besides studies of survival, especially the more specific developmental processes like nervous system development need to be addressed experimentally. Before new high-dose, flavonoid-based therapeutic strategies are developed for pregnant women further research on the safety of these compounds is clearly needed.

Abstract
The discovery of bioactive molecules from botanical sources is an expanding field, preferentially oriented to plants having a tradition of use in medicine and providing high yields and availability. Temperate forage legumes are Fabaceae species that include worldwide-important crops. These plants possess therapeutic virtues that have not only been used in veterinary and folk medicine, but have also attracted the interest of official medicine. We have examined here Medicago sativa (alfalfa), Trifolium pratense and T. repens (clovers), Melilotus albus and M. officinalis (sweet clovers), Lotus corniculatus (birdsfoot trefoil), Onobrychis viciifolia (sainfoin), Lespedeza capitata (roundhead lespedeza), and Galega officinalis (goat's rue). The phytochemical complexes of these species contain secondary metabolites whose pharmacological potentials deserve investigation. Major classes of compounds include alkaloids and amines, cyanogenic glycosides, flavonoids, coumarins, condensed tannins, and saponins. Some of these phytochemicals have been related to antihypercholesterolemia, antidiabetic, antimenopause, anti-inflammatory, antiedema, anthelmintic, and kidney protective effects. Two widely prescribed drugs have been developed starting from temperate forage legumes, namely, the antithrombotic warfarin, inspired from sweet clover's coumarin, and the antidiabetic metformin, a derivative of sainfoin's guanidine. Available evidence suggests that temperate forage legumes are a potentially important resource for the extraction of active principles to be used as nutraceuticals and pharmaceuticals.

Abstract
The Italian herbal products market is the most prosperous in Europe. The proof is represented by the use of these products in several marketing categories, ranging from medicine to nutrition and cosmetics. Market and legislation in Italy are at the same time cause and consequence of this peculiar situation. In fact, the legislation on botanical food supplements in Italy is very permissive and at the same time the market shows an overall satisfaction of users and strong feedback in terms of consumption, which brings a widening use of medicinal plants, formerly the prerogative of pharmaceuticals, to other fields such as nutrition. This review summarizes the market and normative panorama of herbal products in Italy, highlighting the blurred boundaries of health indications, marketing authorizations and quality controls between herbal medicines and non pharmaceutical products, such as food supplements, cosmetics and other herbal-based “parapharmaceuticals”.

Abstract
The Boswellia gum resin extracts have been used in traditional medicines because of their remarkable anti-inflammatory properties. Nowadays, these extracts are on the market as food supplements. β-Boswellic acid (βBA) is one of the main pentacyclic triterpene components, among the family of BAs, of the Boswellia gum resins. BAs have been broadly studied and are well known for their wide anti-inflammatory and potential anticancer properties. In this paper, a mass spectrometry-based chemoproteomic approach has been applied to characterize the whole βBA interacting profile. Among the large numbers of proteins fished out, proteasome, 14-3-3 and some ribosomal proteins were considered the most interesting targets strictly connected to the modulation of the cancer progression. In particular, because of their recent assessment as innovative chemotherapeutic targets, the ribosomal proteins were considered the most attractive βBA partners, and the biological role of their interaction with the natural compound has been evaluated.

Abstract
This study determines the occurrence and concentration levels of artificial low-calorie sweeteners (LCSs) in food and food supplements on the Italian market. The analysed sample set (290 samples) was representative of the Italian market and comprised of beverages, jams, ketchups, confectionery, dairy products, table-top sweeteners and food supplements. All samples were analysed via UPLC-MS/MS. The method was in-house validated for the analysis of seven LCSs (aspartame, acesulfame-K, saccharin, sucralose, cyclamate, neotame and neohesperidin dihydrochalcone) in food and for five LCSs (aspartame, acesulfame-K, saccharin, cyclamate and sucralose) in food supplements. Except for cyclamate in one beverage which exceeded the maximum level (ML) with 13%, all concentrations measured in food were around or below the ML. In food supplements, 40 of the 52 samples (77%) were found to be above the ML, with exceedances of up to 200% of the ML.
