Jellied meat helps skin look healthy while some people buy expensive collagen supplements, others get it from their regular jellied meat. When meat, bones and cartilage are cooked for a long time, the collagen turns into gelatin, which provides the body with amino acids. They are essential for maintaining the health of the skin, muscles and connective tissues. The dish can also be good for joints, ligaments and bones, nutritionist Daria Roskova told the section. For a healthy person, 100-150 grams of jellied meat once or twice a week is enough.
