What you feed your body has a direct correlation to how your brain functions. Diet and nutrition impact cognition, attention, sleep, and mood. According to the Harvard Health Blog, studies show that people who eat “clean” or “whole” diets high in vegetables, fruits, unprocessed grains, and lean meats, are more likely to experience better emotional health. The better you want your brain to perform, the more unprocessed foods, proteins, vegetables, and fruits you should eat. Research shows that protein promotes alertness in the brain. Carbohydrates do the opposite. And artificial colors and flavors are even worse.
Pesticides, specifically organophosphates, found on fruits and vegetables may be linked to ADHD. Western diet — processed meats, fast foods, high-fat dairy products, and sugary foods — doubled the risk of having an ADHD diagnosis, compared with a healthier diet.
