4 "Genius Foods" That Make You Smarter, Happier, and More Productive

Max Lugavere has always been interested in nutrition, but it wasn't until his mother started showing the early signs of dementia that he started researching the link between food and the brain. "After the trauma of her diagnosis and seeing the way cases like hers are treated in the top neurology departments in the U.S., I became laser-focused on learning how food affects cognition," he tells MyDomaine. "What shocked me was finding that often, changes begin in the brain decades before the first symptom. I decided to use my platform to educate others on how powerful their choices are when it comes to brain function."

Lugavere's New York Times best-selling book, Genius Foods, aims to do just that—though he admits he's benefited from the research process as much as readers. "It blew my mind that one in seven younger people complain of memory problems, that the odds of being diagnosed with Alzheimer’s if you reach the age of 85 today are 50%, and that one in four women in their 40s and 50s are on antidepressants," he says. "Clearly our ancient brains are struggling to thrive in the modern world."

Lugavere believes that protecting and improving the cognitive function of the brain takes place in the kitchen. In his book, Lugavere outlines the "genius foods" that make you "smarter, happier, and more productive." Sound too good to be true?
