Marrow, raw

Marrow is a type of squash eaten as a vegetable. These figures describe the raw flesh only, with the seeds removed. Per 100g, it contains 96g of water, 2.2g of carbohydrate, 0.2g of fat and 11mg of vitamin C. It also provides small amounts of protein and other vitamins and minerals.

Vitamin C helps the body form collagen, which supports skin and other tissues, and helps with the absorption of iron from plant foods. Marrow has a low energy content, although added oil or butter will increase the energy and fat content of a prepared dish. Full nutritional figures are in the tables below.
