Much depends on what you eat, especially how you age, feel, and focus. So why not feed your body and brain with clean, high-octane fuel? Here's how.
Pan-Seared Salmon with Pear and Walnut Spinach Salad
Wild salmon has less saturated fat, fewer calories, and 5 to 10 times fewer contaminants and persistent organic pollutants (POPs) than farm-raised (in early studies, POPs have been linked to impaired brain development, type 2 diabetes, and obesity). There’s no need to give up all farmed salmon, and eating some is always better than none. Aim to eat at least 1 to 2 servings of omega-3 rich fatty fish weekly.
Plus, a 2014 study from the University of Pittsburgh found that people who eat fish of any type on a weekly basis have larger gray matter volumes in the brain—the area responsible for memory and speech—than those who don't.
A 2015 study found that people who ate one to two servings of leafy greens per day had the mental abilities of someone 11 years younger than those who ate none.
