Too much about the country's sixth-most fatal disease, Alzheimer's, remains a mystery. A healthier diet is not a cure-all, but combined with sleep and exercise, it's a great place to start. These medical professionals share their personal meal plans.

BREAKFAST I often skip it.

LUNCH My first meal is typically around noon, favoring lots of colorful, above-ground vegetables and a protein source like free-range eggs or wild fish, with everything covered in lots of organic, extra-virgin olive oil.

DINNER Usually similar. I consume fermented foods daily. I really like kimchi, a traditional Korean fermented cabbage that’s loaded with probiotic bacteria. I also eat a good source of prebiotic fiber each day to nurture gut bacteria. This may be jicama, dandelion greens, asparagus, onions, garlic, or artichokes.

BREAKFAST I don’t get hungry until about 10 a.m., so I start with hot water and lemon, move on to black coffee, then I might have some sheep’s yogurt with blueberries and chopped nuts.

LUNCH By 10, I’m eating a cup of soup. If I have a frittata in the fridge from the weekend, I’ll nibble on that.

DINNER Depending on the season, it might be a steak salad, a curry, or soup—all accompanied by lots of vegetables. I also keep myself hydrated with herbal tea, green tea, and infused waters.
