Too many glasses of wine can leave your brain feeling a little fuzzy, but one with dinner is just right. Having that nightly wine may even protect your brain from a blood clot or bleed. People who drink one or two drinks per night have an eight percent lower risk of having a stroke. However, don't go crazy. Heavy drinkers, having at least four drinks per night, have a 14 percent increased risk of stroke than those who don't drink or only drink occasionally.

A glass of red wine with dinner may also put you at lower risk for dementia. Moderate red wine drinkers have a 23 percent lower risk of developing dementia than those who don't drink.

However, none of these findings should ever suggest that you have to drink wine in order to be healthy. "We don't recommend that nondrinkers start drinking," Professor Edward J. Neafsey told Medical Times Today. "But moderate drinking, if it is truly moderate, can be beneficial." So next time your mother-in-law raises an eyebrow as you help yourself to a glass of wine while holding the baby in the other hand, just brush it off. You're working on your brain health!
