amount of calories in milk
Mature breast milk looks very different from colostrum, the milk produced in the first few days after birth. According to Guthrie (1989), each 100 mL of colostrum yields approximately: â¢ 58 calories. â¢ 5.3 g carbohydrates. â¢ 2.9 g fat. â¢ 3.7 g protein. Colostrum is low in fat and carbohydrates. As a result, there are fewer calories in breast milk for the first few days of a babyâs life. Colostrum is yellow because it contains high levels of beta carotene (10 times more than is found in mature milk). Colostrum also contains elevated levels of vitamin E and zinc.
