One health benefits of red wine include its ability to improve cholesterol, fight free radical damage, help manage diabetes, fight obesity and prevent cognitive decline. Not all wines are created equally, some wines have more micro-nutrients than others (Vine grapes grown in cooler climates have higher resveratrol levels than those from warmer climes (such as California and Spain). The varieties with most resveratrol in the wine include Malbec, Petite sirah, Merlot, St Laurent and Pinot noir.
How much red wine can you drink?
All the studies point to regular yet low intake of red wine. A great way to drink red wine is a spritzer (just add soda), it helps keep you hydrated and slows down the drinking!
Testosterone and red wine
One of the ways testosterone is eliminated from your body is through urine. An enzyme called UGT2B17 (expressed in the prostate) attaches specific molecules to testosterone, enabling your body to get rid of it. But researchers in the UK found that quercetin, a compound in red wine, blocks UGT2B17 in lab studies. That means potentially elevated testosterone levels in your bloodstream, and less in your urine.
Another reason why red wine inhibits aromatase enzyme is probably because of a polyphenol called resveratrol, which has been shown to inhibit aromatase, decrease estrogen, and to increase testosterone levels. Resveratrol is present in grapes, berries and other plants, exerts several beneficial effects including antioxidant, anti-inflammatory, anti-aging and anti-carcinogenic.
