In which of the following conditions is the major protein whey more easily digested than casein?

Whey protein is known for its high digestibility and rapid absorption compared to casein protein, which forms a gel or curd in the stomach and leads to slower digestion. In the context of human milk, whey makes up a significant proportion of the protein content, and its composition is tailored to meet the nutritional needs of infants.

Human milk contains a higher ratio of whey to casein, making it easier for infants to digest and absorb the necessary nutrients quickly, which is critical for their growth and development. This higher digestibility translates to proteins that can be effectively utilized by a growing infant's body without causing excessive gastrointestinal distress.

In contrast, infant formulas and cow's milk often contain a higher proportion of casein, which can lead to slower digestion and potentially cause feeding issues like constipation in some infants. Soy milk also behaves similarly due to its protein composition, which is not identical to that of human milk.

Thus, the notable aspect of human milk is its ideal protein balance favoring whey, answering the query about the easier digestion of whey in this specific context.
