Protein & dairy, minus the myths.

Protein isn't a 'meat molecule.' Dietary protein is just chains of amino acids, and your body breaks all protein down into that same shared pool of building blocks — whether it came from a steak or a bowl of lentils.

Plant foods — beans, lentils, soy, grains, nuts, and seeds — supply protein and amino acids. MedlinePlus states plainly that you do not need to eat animal products to get all the protein you need.

Cattle build large bodies on plants. Microbes in the cow's rumen ferment plant fiber and synthesize microbial protein; the cow then digests those microbes, getting high-quality protein and amino acids that ultimately trace back to plants and microbes.

A varied plant-based diet with enough total calories can meet protein and amino-acid needs. MedlinePlus notes you don't need every amino acid at every meal — balance across the whole day is what matters — and dietetics bodies agree well-planned plant-based patterns can be nutritionally adequate.

Mature human milk is actually relatively low in protein (roughly 0.9–1.2 g per 100 mL) — among the lowest of mammalian milks — yet it supports healthy infant growth. Rapid early growth doesn't require a protein-packed diet.

Comparative biology only — this is not infant-feeding advice. Follow your pediatrician's guidance on feeding infants.

Digesting lactose as an adult (lactase persistence) is an inherited adaptation. About 65% of people worldwide have reduced lactase activity after infancy, so adult lactose tolerance is the exception in much of the world — not the universal human default.
