Kidney, ox, stewed

Ox kidney is an organ meat from cattle. The figures here describe stewed kidney with the skin and core removed. It mainly provides protein, alongside fat and a range of vitamins and minerals. Per 100g, it contains 25g of protein, 4.4g of fat, 9mg of iron and 38µg 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. Ox kidney also contains cholesterol and saturated fat, which may be relevant when considering overall dietary intake. Full nutrient figures are provided in the tables below.
