Colostrum is lower in which nutrient compared to mature milk?

Colostrum, which is the first milk produced by the mother after giving birth, is known for its unique composition that differs significantly from mature breast milk, particularly in terms of fat content. Compared to mature milk, colostrum is lower in fat. This lower fat content is beneficial in the early days postpartum, as colostrum is concentrated with antibodies and nutrients that provide essential immune defense for the newborn, prioritizing strength and immune protection over energy density.

Mature milk transitions to a higher fat content after a few days, which supports the growing infant's energy needs. Overall, while colostrum is lower in fat, it more than compensates with other crucial nutrients such as proteins, antibodies, and various bioactive components that are pivotal at the beginning of an infant’s life. This is why recognizing the specific nutrient distribution in colostrum, especially the relative scarcity of fat compared to mature milk, is vital for understanding its role in early infant nutrition.
