BACKGROUND: The human body relies on several aging defense mechanisms (ADMs) to limit damage induced from pro-aging stressors (aging aggressors). However, such protective mechanisms can be compromised, leading to accelerated aging. The skin provides a model to probe the effects of an oral nutritional intervention on ADMs in response to ultraviolet radiation (UVR)-induced damage. OBJECTIVE: To determine whether supplementation with a novel nutritional and phytonutrient blend could protect against UVR-induced skin damage and positively influence facial skin attributes and characteristics by bolstering ADMs...

TRPA1 is a ligand-activated cation channel found in the intestine and other tissues. Components of food that stimulate TRPA1 receptors (phytonutrients) include allyl isothiocyanate, cinnamaldehyde and linalool, but these may also act at other receptors. Cells lining the intestinal mucosa are immunoreactive for TRPA1 and Trpa1 mRNA occurs in mucosal extracts, suggesting that the TRPA1 receptor is the target for these agonists. However, in situ hybridisation reveals Trpa1 expression in 5-HT containing enteroendocrine cells, not enterocytes...

The consumption of carotenoid phytonutrients, largely as part of plant tissue, has been associated with a number of health benefits. Epidemiological and other studies support a link between higher dietary intake and tissue concentrations of carotenoids and lower risk of chronic diseases such as heart disease, diabetes, and some cancers. Evidence also suggests that increased levels of carotenoids can help maintain healthy cognitive function, especially into older age. Carotenoids mediate their beneficial effects via several mechanisms including cell growth regulation and modulation of gene expression and immune activity...

Pigmented sweet potatoes (SPs) are outstanding sources of anthocyanin, β-carotene and other color-related phytonutrients. However, fresh SP roots are highly perishable and difficult to store. To reduce losses and extend their uses, fresh SP could be converted into flour. SP cultivars with deep purple (Phichit 65-3) and orange-fleshed (T101) colors newly developed in Thailand were studied. The influence of drying methods on physico-chemical properties, anthocyanin, β-carotene and antioxidant activity retentions of purple and orange-fleshed SP flours (SPFs) was investigated...

Evidence on the association between dietary component, dietary pattern and nasopharyngeal carcinoma (NPC) is scarce. A major challenge is the high degree of correlation among dietary constituents. We aimed to identify dietary pattern associated with NPC and to illustrate the dose-response relationship between the identified dietary pattern scores and the risk of NPC. Taking advantage of a matched NPC case-control study, data from a total of 319 incident cases and 319 matched controls were analyzed. Dietary pattern was derived employing partial least square discriminant analysis (PLS-DA) performed on energy-adjusted food frequencies derived from a 66-item food-frequency questionnaire...
