People with coronary heart disease can eat a small amount of lean mutton, as mutton contains not only high-quality protein, vitamins, and trace elements needed by the human body, but also abundant minerals. Regular consumption of mutton can enhance immunity and disease resistance. Although individuals with coronary heart disease need to make reasonable adjustments to their diet structure in daily life, under the guidance of a doctor, effective medications should be used to treat high blood pressure, regulate blood lipids, and lower blood sugar. A low-fat, low-salt diet is recommended, and it is important to avoid eating animal offal, fatty meats, fried foods, and sweets, which are beneficial for improving coronary heart disease. Lean mutton can be eaten but avoid fatty mutton, and consume it in small amounts without overeating.
