Question: what is the difference between human breast milk and cow milk?
Answer: Both are about 88% water, but human milk has 7% carbohydrate, 1.3% protein, and 4.1% fat. Cow's milk has about 4.5% carbohydrate, 3.3% protein, and 3.9% fat. ... Calves need to grow quickly, so there's more protein in cow's milk than in human milk.
