Beans | Foods that Fight Fatigue | Caring.com: "Beans make a terrific replacement for red meat, another rich source of protein and iron, but beans are lower in calories and are nearly fat-free. In addition, beans place a lesser burden on the digestive system than red meat, requiring less energy to be assimilated into the body. In other words, you're a lot more likely to feel tired and heavy after eating a steak than you are after eating a serving of beans.
The manganese and copper in beans protect the mitochondria in our cells that are responsible for energy production, while magnesium relaxes nerves and muscles and keeps blood circulating smoothly, keeping physical and mental fatigue at bay. Vitamin B1 (thiamin) contributes to energy production, and, along with potassium, supports proper muscle and nerve function. And last -- but not least -- there's iron. Iron not only helps produce energy, it also boosts oxygen distribution throughout body, easing mental fatigue. Iron provides immune system support as well -- and a healthy immune system makes you less susceptible to fatigue in all its forms."
