Food Focus: Whole & Minimally Processed Foods
Buying foods as close as possible to their natural state leaves important nutrients—like fiber, vitamins, and minerals—largely intact. For instance, brown rice trumps white. A fresh, juicy peach crushes canned. Also, the less that’s “done” to a food, the less likely it is to contain potentially problematic additives1 like artificial food dyes and preservatives.
If fresh produce isn’t easily accessible, frozen (versus canned) is a great, minimally processed alternative. Go organic, if affordable, and you can also minimize exposure to pesticides, which some research2 has linked to ADHD. And the old rule of thumb about food labels holds true: The fewer and more recognizable the ingredients, the better choice it probably is.
