Dark meat might be fattier than white, but chicken thighs are considerably higher in iron than breast meat. Female endurance athletes often run the risk of being anemic. Plus dark chicken meat is high in zinc. Missing out on both iron and zinc means your energy levels can wane, nothing you want to experience while training. When compared to red meat, chicken thighs offer iron, zinc, and B vitamins but considerably less fat. Thighs are easy to make and relatively inexpensive.
