Kidney, ox, raw

Ox kidney is an organ meat from cattle. The figures here describe it raw, rather than cooked. It mainly provides protein, along with B vitamins and minerals including iron and selenium. Per 100g, raw ox kidney contains 17g of protein, 2.1g of fat, 7.2mg of iron and 15µg of vitamin B12.

Protein supports the growth and repair of body tissues. Iron is needed to make haemoglobin, which carries oxygen in the blood, while vitamin B12 supports normal nerve function and red blood cell formation. Kidney also contains cholesterol, which is distinct from saturated fat. Cooking can change nutrient concentrations through changes in water content. Full nutrient figures for the raw food are given in the tables below.
