Transitional human milk is breast milk produced as early milk, known as colostrum, changes towards mature milk after birth. It mainly provides carbohydrate and fat, alongside protein and smaller amounts of vitamins and minerals. Per 100g, the supplied data show 281 kJ of energy, 3.7g of fat, 6.9g of carbohydrate and 1.5g of protein.
Fat and carbohydrate provide energy for an infant’s growth and development, while protein supports the formation and repair of body tissues. The main sugar in human milk is lactose. Breast milk composition varies between mothers and changes during lactation, so these figures describe a sample rather than every feed. Full nutrient figures are in the tables below.

About these figures
Values are per 100g of the food as described (Mixed sample, 15 mothers at 10th day post partum and literature sources). "Trace" means only a very small amount was found. Nutrients that were not measured are not shown. Salt is calculated from sodium.
