Loss of trans-resveratrol in young red wines

In general, cis-resveratrol shows fewer health effects than trans-resveratrol, including its anti-inflammatory power. According with this study it is possible that older red wines will not provide the same degree of health benefits compared to younger red wines. However, further work is required to confirm the dependency of resveratrol flux on the age of the wine in question.

Ιn vitro effects of Vitis vinifera L. leaf extract on UV-stressed human dermal fibroblasts

Natural products such as plant extracts have been implicated in the skin antioxidant and anti-aging cellular protection against environmental stress such the one caused by UV radiation. This post summarizes the results of a study where the in vitro effect of a leaf extract from Vitis vinifera L. on UV-stressed primary human dermal fibroblasts was assessed. The results of the study will contribute to understanding further the molecular mechanisms governing anti-aging and stress responses in human dermal cells and may lead to new target molecules for skin-care products.

Fertility and Wine

One may well be skeptical about the claims made for the purported health benefits of wine, but beware of questioning Greeks bearing gifts, and surely nobody can, in good faith, deny the mood enhancement that moderate wine drinking can bring? True, when it is abused it can have disastrous and life-destroying consequences, especially when in conjunction with addictive tendencies. However, when consumed in sensible quantities, it can be and is, as the Greeks realized, one of life’s great pleasures.

2,4,6-trihydroxyphenanthrene: a new trans-resveratrol derivative detected in red wine after UV irradiation.

T2,4,6-trihydroxyphenanthrene (THP) results from cyclization of the trans-to the cis-isomer of resveratrol one of the most abundant polyphenols in red grapes and red wine. It has been demonstrated that THP can induce DNA damage through a pro-oxidant mechanism. On the other hand, due to the extended delocalization and conjugation of the πelectrons over the entire molecule, THP displays a significantly increased antioxidant activity compared to RSV with potential benefits on human health. Whatever the effect of THP on human health, it becomes important to establish its actual presence not only in RSV-containing food and beverages but even in cosmetics that, by their nature, are subject to UV radiation.

How efficient is resveratrol as an antioxidant of the Mediterranean diet, towards alterations during the aging process?

Yesterday I published in the blog of our conference page “Wine Consumption in the Mediterranean Diet: A clarification about health effects” a post about the new Spanish Society of Community Nutrition guidelines, published last November 5. This proposal of food-based dietary guidelines s does not recommend in any case the consumption of alcoholic beverages. However, there are scientific evidence for health benefits of some wine components like the ones described in this review. Consumption of wine is a controversial issue, therefore, discussions forums like the conference that will be held in Vila Nova de Gaia at June 4 are very important.

Post Nº 100

This is the post number 100. One hundred of weekends that I spend writing, reading, illustrating, editing and publishing the posts. The time that I spent do it is just part of the time I stole to the family, special to my youngest daughter, so today I decided to involve her in this project. The illustration is her authorship.
