Why a low-calorie diet for angina pectoris?
Disease description:
My father has angina, and he doesn't pay much attention to his diet—he especially loves eating meat. However, the doctor advised him to eat less meat and stick to light, low-calorie foods. Why is a low-calorie diet recommended for angina?
Doctor's answer (1)
Dr. Li Man
Patients with angina should follow a low-calorie diet to promote better digestion and absorption in the gastrointestinal tract. Angina is a common manifestation of coronary heart disease, which is primarily caused by atherosclerosis of the coronary arteries and is a prevalent type of heart disease. Patients often have some degree of cardiac dysfunction. Consuming high-calorie foods can increase blood flow demand in the digestive system, thereby placing additional strain on the heart and potentially triggering angina attacks.
