Cottage Cheese

Cottage cheese is a fresh cheese product made by curdling milk with rennet or acid, then draining the whey and mixing the curds with cream or milk. It originated as a byproduct of butter-making in home dairies and is now produced commercially worldwide. Common culinary uses include breakfast bowls, desserts, savory sides, smoothie bases, and baking applications.

Cottage cheese contains approximately 11–12 grams of protein per 100-gram serving, predominantly casein, a slowly digesting milk protein. A half-cup serving (approximately 113 g) provides a moderate number of calories that varies meaningfully by fat level, 2–5 grams of fat (primarily saturated), and minimal carbohydrate. Because standard cottage cheese is not fermented, it does not contain live probiotic cultures, though some commercial varieties are made with added live cultures. Lactose content is low compared to fluid milk, typically 2–3 grams per half-cup serving, making it tolerable for many people with lactose sensitivity.

Protein and Satiety

The high casein protein content in cottage cheese promotes prolonged satiety and supports muscle protein synthesis when consumed in adequate amounts alongside resistance training. Casein forms a gel in the stomach, slowing gastric emptying and extending the sense of fullness, which may support eating patterns in calorie-controlled contexts.

Tolerance and Population Guidance

Cottage cheese is a dairy product and unsuitable for those with milk allergy; individuals with lactose intolerance usually tolerate it well due to low lactose levels, though tolerance varies. Some people experience bloating or digestive discomfort. Cottage cheese is typically high in sodium (250–390 mg per half-cup serving), which is relevant for individuals managing blood pressure. Those with kidney disease requiring potassium or phosphorus restriction should monitor intake as cottage cheese contains meaningful amounts of both minerals.
