Ran across an interesting piece on USDA from Tom Vilsack, the department’s head. From that piece, a quote about breakfast:
USDA researchers have made discoveries that prove eating a protein-rich breakfast increases the brain’s level of dopamine, a chemical that helps reduce food cravings and overeating later in the day. USDA scientists recorded brain electrical activity during the performance of mental arithmetic in children and found that those who ate breakfast were more efficient at solving math problems than those who did not.
If you’re looking to push past mid-morning sluggishness and step lightly on the planet, opt for plant-based protein-rich foods: quinoa, edamame, beans & legumes including peanut butter, wild rice, nuts and also processed items including tofu, tempeh and seitan (more info from Prevention magazine here and here). Eggs and dairy (Greek yogurt) pack a protein punch too.
