Milk is a great source of protein, containing Whey & Casein.  Drinking milk will provide your body with amino acids which help rebuild that muscle you just destroyed during your workout!  It also supplies us with Calcium (to keep our bones strong), Vitamin A (for vision) and Vitamin D (classified as a steroid hormone).  So try to start including a small amount of milk into your diet.  We drink Unsweetened Almond Milk which is good for those of you that have allergies to lactose, soy, or gluten…but its downfall is it doesn’t provide the protein (whey/casein) like the others do.   🙂
