The scientific literature indicates that chokeberry is widely used as a supplement to support the maintenance of the body’s homeostasis by reducing inflammation and oxidative stress. In recent years, positive effects of chokeberry on intestinal parameters have also been observed. Oxidative stress, inflammation and, according to recent reports, also the gut microbiome are closely related to the overall well-being and health of the population. This study, therefore, attempts to summarise all the health benefits of black chokeberry supplementation. This study was registered in PROSPERO (International Prospective Register of Systematic Reviews) under registration number CRD42023395969. Additionally, the systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) method. Electronic databases were searched in Web of Science, PubMed, Scopus and EBSCO using the following combination of the words ‘chokeberry or aronia’ and ‘inflammation or oxidative stress or microbiota or microbiome or permeability or gut’. Ultimately, fifty-seven studies were summarised in the review. Data analysis showed that black chokeberry has a positive effect on the reduction of inflammation, oxidative stress and intestinal microflora, but the size of the changes varies and depends on many variables. Therefore, the researchers concluded that the compounds found in black chokeberry play a pivotal role in maintaining the overall balance within the system. This is a crucial consideration given the tendency for disturbances in organismal homeostasis to accompany disease processes and various disorders. However, further research is necessary to elucidate the mechanisms and optimise its use fully.

The world is experiencing a global push toward smart agriculture to help feed the burgeoning population by increasing food security while reducing the carbon footprint of food production. The guidelines for healthy eating have increased globally from five to seven servings of vegetables a day and this had led to the quest for a sustainable form of vegetable production that will reduce the carbon footprint and still provide consumers with the required nutrients. Microgreens contain more nutrients than some mature vegetables and can be cultivated on vertical farms, offering a different approach with the potential to resolve environmental and health challenges. Microgreens are young plantlets grown from the seeds of edible leafy vegetables and are usually eaten raw. They contain high levels of bioactive compounds and can be processed into oils to create valuable cosmetic products. Microgreens have become well-known to chefs and are gaining popularity in upmarket grocery outlets. Consequently, growing microgreens are presenting huge market opportunities worldwide. Their nutritional benefits, easy production methods and short production cycle are some of the reasons they are attractive to growers. The most important factors affecting the growth of microgreens are micro and macro-climates. One challenge to producing microgreens is that the growing environment is ideal for microbial organisms to thrive. As such, microgreens are prone to foodborne pathogens such as E. coli, Listeria and Salmonella. Consequently, the microgreens industry is facing various setbacks including product recalls from Salmonella and Listeria food poisoning outbreaks. In addition, the short shelf-life of microgreens is a serious challenge for getting microgreens to market, this is driving studies in several post-harvest treatments. This review examines the nutrient content and health benefits of microgreens and factors affecting microgreens' growth: temperature, humidity, photoperiod, fertilization, etc. and post-harvest treatments, all of which can potentially impact microbial growth, the phytochemical content and the physical appearance of microgreens bound for the market.

Camel milk has been consumed for centuries due to its medicinal and healing properties. The present study aims to investigate the consumption patterns of camel milk and perceived benefits and risks among adults in the United Arab Emirates. A self-administered online questionnaire was developed in English and Arabic languages and was completed online by 852 adults. Socio-demographic characteristics, camel milk consumption patterns and perceived knowledge of the benefits and risks of camel milk were investigated. About 60 % of the participants have tried drinking camel milk, but only a quarter (25⋅1 %) were regular consumers. The most consumed camel milk products after fresh milk were yoghurt and flavoured milk. The most popular additions to camel milk were honey, turmeric and sugar. Most consumers had less than one cup of camel milk per day (57⋅0 %). Camel milk consumers preferred it over other types of milk due to its nutritional value (66⋅4 %) and medicinal properties (39⋅3 %). Among consumers, 58⋅4 % reported consuming unpasteurised camel milk. Reasons included the belief that it is fresher (87⋅2 %), better for the immune system (41⋅6 %), and higher in nutrients (39⋅2 %). Overall, participants had inadequate knowledge about the health benefits of camel milk (7⋅11 ± 5⋅3 out of 25). Males and camel milk consumers had a significantly higher knowledge about the health benefits of camel milk compared to females and non-consumers (P < 0⋅05). Although positive perceptions were common, misperceptions appear to be prevalent among non-consumers. Consuming unpasteurised camel milk is a major public health concern, thus national regulations are essential.

This article evaluates the long-term impacts of the Chicago Child-Parent Centers (CPC), a comprehensive early childhood program launched in the 1960s, on physical and mental health outcomes. This study follows a cohort of 1539 participants born in 1979–1980 and surveyed most recently at age 35–37 by employing a matched study design that included all 989 children who entered CPCs at ages 3 and 4 (1983-1985) and 550 comparison children of the same age from randomly selected schools participating in the usual district early childhood programs in kindergarten. Using propensity score weighting that addresses potential issues with differential attrition and non-random treatment assignment, results reveal that CPC preschool participation is associated with significantly lower rates of adverse health outcomes such as smoking and diabetes. Further, evaluating the economic impacts of the preschool component of the program, the study finds a benefit-cost ratio in the range of 1.35–3.66 (net benefit: $3896) indicating that the health benefits of the program by themselves offset the costs of the program even without considering additional benefits arising from increased educational attainment and reduced involvement in crime reported in earlier cost-benefit analyses. The findings are robust to corrections for multiple hypothesis testing, sensitivity analysis using a range of discount rates, and Monte Carlo analysis to account for uncertainty in outcomes.

Volunteerism has been increasingly recognised as a health promotion activity for older adults. However, volunteerism has largely been the domain of those who are in good health with few to no physical limitations, and there is limited information about the experiences of older adults with disabilities. This study explores why older adults with mobility-limiting disabilities engage in volunteer work and their perceptions of the personal benefits of volunteering. Twenty older adults, from three Midwest towns in the United States of America, participated in semi-structured, in-depth, face-to-face interviews. Participants in this study identified as having serious difficulty walking or climbing stairs due to a health condition and had volunteered in the last year. Participants were selected purposively for maximum variation in terms of type of disability/impairment, race, gender and age. The constant comparative method of analysis was used to identify themes from their discussions. When asked about why they volunteer and the personal benefits of volunteering, participants discussed seeking out activities that were meaningful to them for both altruistic and more self-directed reasons. They identified a number of physical and emotional health benefits that they saw as directly and indirectly related to being able to participate in these meaningful activities. Findings from this study suggest that, for older adults with disabilities who are interested in volunteer activities, volunteerism can be a beneficial health promotion activity and a potential mechanism for increasing opportunities for meaningful inclusion and participation in their communities.

Anthocyanins are flavonoids widely spread in various plant species as a major phyto-pigment. In recent years, interest in using anthocyanins as a feed ingredient has increased markedly owing to their health and other benefits. Anthocyanins possess various pharmacological properties, including anti-inflammatory, immunomodulatory, anticancer, antidiabetic, neuroprotective, anti-obesity and antioxidant effects. Dietary consumption of anthocyanins has revealed benefits in animal performance. Little is known about health-promoting effects of anthocyanins in avian species, but anthocyanin-rich dried fruits have shown positive effects on certain pathological conditions and health promoting markers in human and other animals. This review aims to gather information regarding health benefits of anthocyanins and highlight therapeutic and potential health beneficial effects of anthocyanins for poultry. Additionally, it explores these biologically important flavonoids as alternative ingredients in poultry feed to replace synthetic nutrients and medicines. The available literature reports studies involving use of anthocyanins focused on human, mice and in vitro models. However, there is a need to explore mechanism of action at molecular level to understand potential beneficial effects of anthocyanins in avian species.

Designer foods of animal origin are produced either by feeding specific diets, or using new techniques like genetic engineering, cross-breeding. Designer eggs are an important type of functional foods. With the advancement of poultry industry, there is a rising interest in poultry biotechnology for altering the egg composition by genetic and nutritional manipulations for human health. This can be done by modifying cholesterol concentration and its fractions, lipid profile, fatty acids, amino acids and minerals or through adding therapeutic pharmaceutical molecules. Designer eggs provide vegetarian, safe, immune powered, specialty or organic foodstuffs which can have improved vitamins, minerals, balanced ratio of omega-6 to omega-3 fatty acids, lowered total cholesterol, additional boost of antibodies and essential pigments such as carotenoids. From the relevant scientific literature, functional eggs can be considered as human designer food. This review describes the concepts of designer eggs and their health benefits and nutritional values.

The supplementation of livestock rations with herbs containing bioactive components, such as rosmarinic acid (RA), have shown promising results as a natural feed additive in promoting growth, productive and reproductive performance, feed utilization, fertility, anti-oxidant status and immunologic indices. Furthermore, RA reportedly reduces the risks of various animal diseases and mitigates side effects of chemical and synthetic drugs. RA is a natural polyphenol present in several Lamiaceae herbs like Perilla frutescens, and RA is becoming an integral component of animal nutrition as it counters the effect of reactive oxygen species induced in the body as a consequence of different kinds of stressors. Studies have further ascertained the capability of RA to work as an anti-microbial, immunomodulatory, anti-diabetic, anti-allergic, anti-inflammatory, hepato- and renal-protectant agent, as well as to have beneficial effects during skin afflictions. Additionally, RA is favored in meat industries due to enhancing the quality of meat products by reportedly improving shelf-life and imparting desirable flavor. This review describes the beneficial applications and recent findings with RA, including its natural sources, modes of action and various useful applications in safeguarding livestock health as well as important aspects of human health.

Kefir is fermented milk produced from grains that comprise a specific and complex mixture of bacteria and yeasts that live in a symbiotic association. The nutritional composition of kefir varies according to the milk composition, the microbiological composition of the grains used, the time/temperature of fermentation and storage conditions. Kefir originates from the Caucasus and Tibet. Recently, kefir has raised interest in the scientific community due to its numerous beneficial effects on health. Currently, several scientific studies have supported the health benefits of kefir, as reported historically as a probiotic drink with great potential in health promotion, as well as being a safe and inexpensive food, easily produced at home. Regular consumption of kefir has been associated with improved digestion and tolerance to lactose, antibacterial effect, hypocholesterolaemic effect, control of plasma glucose, anti-hypertensive effect, anti-inflammatory effect, antioxidant activity, anti-carcinogenic activity, anti-allergenic activity and healing effects. A large proportion of the studies that support these findings were conducted in vitro or in animal models. However, there is a need for systematic clinical trials to better understand the effects of regular use of kefir as part of a diet, and for their effect on preventing diseases. Thus, the present review focuses on the nutritional and microbiological composition of kefir and presents relevant findings associated with the beneficial effects of kefir on human and animal health.

The Mediterranean diet (MD) emerged as a healthy food regimen long before it could be recognised which nutrients or foods were responsible for its observed benefits, and it was only in the middle of the last century that the first scientific approach ‘The Seven Countries Study’ appeared. Epidemiological and anthropological studies of the MD converged, first by investigating at single nutrients or foods, then by adopting the more holistic approach of dietary patterns (DP), and now with a molecular approach. These studies resulted in convincing evidence that a MD decreases the risk of all-cause mortality and cardiovascular mortality and incidence. A risk reduction of developing type 2 diabetes is probable. Evidence is less stringent for other metabolic diseases and all cancers but from possible to probable for some cancer sites. Although DP showed that the MD has to be considered in its totality, olive oil could have a specific role. Lifestyle factors such as physical activity for energy balance, outdoor life for vitamin D synthesis and conviviality are also probably partly responsible for the health benefits. The MD is a lifestyle well suited for coping not only with personal health but also with wider societal concerns in relation to environment, public health and economy.

The functional properties, including antioxidant and chemopreventative capacities as well as the inhibitory effects on angiotensin-converting enzyme (ACE), α-glucosidase and pancreatic lipase, of three Australian-grown faba bean genotypes (Nura, Rossa and TF(Ic*As)*483/13) were investigated using an array of in vitro assays. Chromatograms of on-line post column derivatisation assay coupled with HPLC revealed the existence of active phenolics (hump) in the coloured genotypes, which was lacking in the white-coloured breeding line, TF(Ic*As)*483/13. Roasting reduced the phenolic content, and diminished antioxidant activity by 10–40 % as measured by the reagent-based assays (diphenylpicrylhydrazyl, 2,2′-azino-bis(3-ethylbenzthiazoline-6-sulphonic acid) and oxygen radical absorbance capacity) in all genotypes. Cell culture-based antioxidant activity assay (cellular antioxidant activity) showed an increase of activity in the coloured genotypes after roasting. Faba bean extracts demonstrated cellular protection ability against H2O2-induced DNA damage (assessed using RAW264.7 cells), and inhibited the proliferation of all human cancer cell lines (BL13, AGS, Hep G2 and HT-29) evaluated. However, the effect of faba bean extracts on the non-transformed human cells (CCD-18Co) was negligible. Flow cytometric analyses showed that faba bean extracts successfully induced apoptosis of HL-60 (acute promyelocytic leukaemia) cells. The faba bean extracts also exhibited ACE, α-glucosidase and pancreatic lipase inhibitory activities. Overall, extracts from Nura (buff-coloured) and Rossa (red-coloured) were comparable, while TF(Ic*As)*483/13 (white-coloured) contained the lowest phenolic content and exhibited the least antioxidant and enzyme inhibition activities. These results are important to promote the utilisation of faba beans in human diets for various health benefits.

Pulses, including peas, have long been important components of the human diet due to their content of starch, protein and other nutrients. More recently, the health benefits other than nutrition associated with pulse consumption have attracted much interest. The focus of the present review paper is the demonstrated and potential health benefits associated with the consumption of peas, Pisum sativum L., specifically green and yellow cotyledon dry peas, also known as smooth peas or field peas. These health benefits derive mainly from the concentration and properties of starch, protein, fibre, vitamins, minerals and phytochemicals in peas. Fibre from the seed coat and the cell walls of the cotyledon contributes to gastrointestinal function and health, and reduces the digestibility of starch in peas. The intermediate amylose content of pea starch also contributes to its lower glycaemic index and reduced starch digestibility. Pea protein, when hydrolysed, may yield peptides with bioactivities, including angiotensin I-converting enzyme inhibitor activity and antioxidant activity. The vitamin and mineral contents of peas may play important roles in the prevention of deficiency-related diseases, specifically those related to deficiencies of Se or folate. Peas contain a variety of phytochemicals once thought of only as antinutritive factors. These include polyphenolics, in coloured seed coat types in particular, which may have antioxidant and anticarcinogenic activity, saponins which may exhibit hypocholesterolaemic and anticarcinogenic activity, and galactose oligosaccharides which may exert beneficial prebiotic effects in the large intestine.

In addition to supplying essential nutrients, some food proteins can confer additional health benefits beyond nutrition. The presence of bioactive proteins and peptides in different foods is a factor not currently taken into consideration when assessing the dietary quality of food proteins. The range of described physiological benefits attributed to bioactive proteins and peptides is diverse. Multiple factors can potentially impact on the ability of a bioactive peptide or protein to elicit an effect. Although some food proteins act directly in their intact form to elicit their effects, generally it is peptides derived from digestion, hydrolysis or fermentation that are of most interest. The levels of bioactive peptides generated must be sufficient to elicit a response, but should not be so high as to be unsafe, thus causing negative effects. In addition, some peptides cause systemic effects and therefore must be absorbed, again in sufficient amounts to elicit their action. Many studies to date have been carried out in vitro; therefore it is important that further trials are conducted in vivo to assess efficacy, dose response and safety of the peptides, particularly if health related claims are to be made. Therefore, methods must be developed and standardised that enable the measurement of health benefits and also the level of bioactive peptides which are absorbed into the bloodstream. Once standardised, such methods may provide a new perspective and an additional mechanism for analysing protein quality which is currently not encompassed by the use of the protein digestibility-corrected amino acid score (PDCAAS).

Omega 3 fatty acids can be obtained from several sources, and should be added to the daily diet to enjoy a good health and to prevent many diseases. Worldwide, general population use omega-3 fatty acid supplements and enriched foods to get and maintain adequate amounts of these fatty acids. The aim of this paper was to review main scientific evidence regarding the public health risks and benefits of the dietary sources of omega-3 fatty acids. A systematic literature search was performed, and one hundred and forty-five articles were included in the results for their methodological quality. The literature described benefits and risks of algal, fish oil, plant, enriched dairy products, animal-derived food, krill oil, and seal oil omega-3 fatty acids.

Equol (EQ) is a metabolite produced by gut bacteria through the chemical reduction of the soya isoflavone daidzein (DE), but only by 30–60 % of the population. EQ is believed to provide benefits derived from soya intake and its production is widely viewed as a relatively stable phenomenon. In a randomised, cross-over intervention with soya foods, seventy-nine pre-menopausal women were challenged with a high-soya and a low-soya diet each for 6 months, separated by a 1-month washout period. Overnight urine was collected at three time points during each diet period and analysed for DE and EQ by liquid chromatography tandem MS. Remaining an EQ producer (EP) or non-producer (NP) or changing towards an EP or NP was assessed using an EQ:DE ratio of ≥ 0·018 combined with a DE threshold of ≥ 2 nmol/mg creatinine as a cut-off point. We observed 19 and 24 % EP during the low-soya and high-soya diet periods, respectively, and found that 6–11 % of our subjects changed EQ status ‘within’ each study period (on an average of 1·2 times), while 16 % changed ‘between’ the two diet periods. The present finding challenges the widely held conviction that EQ production within an individual remains stable over time. The precise factors contributing to changes in EQ status, however, remain elusive and warrant further investigation.

Certain forms of dietary Se may have advantages for improving human Se status and regulating the risk for disease, such as cancers, including colorectal cancer (CRC). The present study compared the effects of a Se-enriched milk protein (dairy-Se) with a Se-rich yeast (yeast-Se) on plasma Se levels and rectal selenoprotein gene expression since we reasoned that if these genes were not regulated, there was little potential for regulating the risk for CRC in this organ. A total of twenty-three healthy volunteers with plasma Se in the lower half of the population range were supplemented with dairy-Se (150 μg/d) or yeast-Se (150 μg/d) for 6 weeks, followed by 6 weeks of washout period. Blood was sampled every 2 weeks, and rectal biopsies were obtained before and after Se supplementation and after the washout period. Plasma Se levels and glutathione peroxidase (GPx) activity, and rectal mRNA of selenoprotein P (SeP), cytosolic GPx-1 (GPx-1), gastrointestinal GPx-2 (GPx-2) and thioredoxin reductase-1 (TrxR-1) were measured. Plasma Se levels increased rapidly in both Se groups (P < 0·001); plasma GPx activity was not significantly changed. Rectal SeP mRNA increased at 6 weeks compared with baseline in both Se groups (P < 0·05); only dairy-Se resulted in a sustained elevation of SeP after the washout period (P < 0·05). Rectal GPx-1 and GPx-2 mRNA were higher with dairy-Se (P < 0·05) than with yeast-Se at 6 weeks. In conclusion, three rectal selenoprotein mRNA were differentially regulated by dairy-Se and yeast-Se. Changes in rectal selenoproteins are not predicted by changes in plasma Se; dairy-Se effectively regulates the expression of several rectal selenoproteins of relevance to the risk for CRC.
