Food allergies are recognised as a global health concern. In order to protect allergic consumers from severe symptoms, allergenic risk assessment for well known foods and foods containing genetically modified ingredients was installed. However, population is steadily growing and there is a rising need to provide adequate protein-based foods, including novel sources, not yet used for human consumption. In this context safety issues such as a potential increased allergenic risk need to be assessed before marketing novel food sources...

SCOPE: To understand the mechanism by which green tea lowers the risk of dementia, focus was placed on the metabolites of epigallocatechin gallate (EGCG), the most abundant catechin in green tea. Much of orally ingested EGCG is hydrolyzed to epigallocatechin (EGC) and gallic acid. In rats, EGC is then metabolized mainly to 5-(3', 5'-dihydroxyphenyl)-γ-valerolactone (EGC-M5) and its conjugated forms, which are distributed to various tissues. Therefore, we examined the permeability of these metabolites into the blood-brain barrier (BBB), and nerve cell proliferation/differentiation in vitro...

Protein digestion is critical for infants. Dissimilarities between infants and adults in food intake and digestive physiology lead to distinct patterns of proteolysis between individuals. However, such differences are not well represented in many studies on protein digestion of baby foods. The complex biological structures of baby foods and the physiology of the infant digestive system are key factors affecting proteolysis during the first two years of life. Well-controlled in vitro studies have demonstrated that varying digestion conditions alter the specificity, rate, and extent of proteolysis of baby foods...

Qian Li, Tao Wu, Rui Liu, Min Zhang, Ruijun Wang
SCOPE: Evidence from animal experiments and clinical medicine suggest that high dietary fiber intake, followed by gut microbiota-mediated fermentation, decreases trimethylamine (TMA) metabolism, the mechanism of which, however, remains unclear. The objective of this analysis was to evaluate, using mice fed with red meat, the effects of soluble dietary fiber (SDF) intervention on TMA metabolism. METHODS AND RESULTS: Low- or high-dose soluble dietary fiber (SDF) from natural wheat bran (LN and HN, low- and high-dose natural SDF), fermented wheat bran (LF and HF, low- and high-dose fermented SDF), and steam-exploded wheat bran (LE and HE, low- and high-dose exploded SDF groups) were used to examine whether SDF interventions in mice fed with red meat can alter TMA and trimethylamine N-oxide (TMAO) metabolism by gut microbial communities in a diet-specific manner...

SCOPE: Normal physiological processes require a robust biological timer called the circadian clock. Dysregulation of circadian rhythms contributes to a variety of metabolic syndrome, including obesity and insulin resistance. EGCG has been demonstrated to possess antioxidant, anti-inflammatory, and cardioprotective bioactivities. The objective of this study was to explore whether circadian clock is involved in the protective effect of EGCG against insulin resistance. METHODS AND RESULTS: The results demonstrated that EGCG reverses the relatively shallow daily oscillations of circadian clock genes transcription and protein expression induced by glucosamine in HepG2 cells...

SCOPE: High glycaemic sugars result in blood glucose spikes, while high doses of post-prandial fructose inundate the liver, causing an imbalance in energy metabolism, both leading to increased risk of metabolic malfunction and type 2 diabetes. Acarbose, used for diabetes management, reduces post-prandial hyperglycaemia by delaying carbohydrate digestion. METHODS AND RESULTS: Chamomile and green teas both inhibited digestive enzymes (α-amylase and maltase) related to intestinal sugar release, as already established for acarbose...

SCOPE: Anorexia of aging, characterized by a decrease in appetite and/or food intake, is a major risk factor of under-nutrition and adverse health outcomes in elderly people. Recent in vitro evidence suggests homoeriodictyol (HED), a naturally occurring, bitter-masking flavanone, as a promising agent to increase appetite and food intake. METHODS AND RESULTS: In two cross-over intervention trials, 30 mg NaHED, either solely (n = 10, Study I) or in combination with a 75g glucose load (n = 17, study II) were administered to healthy adult subjects...
