According to a study published in Frontiers in Human Neuroscience, master sommeliers — or wine experts — have acute senses of smell, along with larger, thicker parts of the brain. It's thought that this thickness can prevent Alzheimer's and Parkinson's more than thinner-brained non-wine drinkers.
"Though we don't know for sure, there is a possibility that when it comes to the brain, thicker is better," Dr. Sarah Banks, head of neuropsychology at the Cleveland Clinic in Las Vegas and author of the study, told the New York Post. "It seems like if you have more brain in those areas, it'll take longer to feel the effects of the disease, but it's speculation."
The brain is 70% from fat, so it is important to consume omega-3 and monounsaturated fats. They help fight the inflammation, transport and absorb vitamins A, D, E and K, which are necessary for the full functioning of the brain. Fats - the present fuel.
In addition to wines brain useful: dried apricots, red cabbage, turmeric, chicken, beets, coconut oil, peas, yogurt.
