Heart patients are allowed to eat squid. Although squid is a high-calorie food with a relatively high fat content, eating it properly will not lead to worsening of the disease in a short period of time, especially in coronary heart disease, which is mainly caused by myocardial ischemia due to narrowing of the blood vessel lumen caused by elevated blood lipids. Even so, it is possible to eat squid appropriately, because a scientifically arranged diet is not going to lead to excessive intake of certain nutrients. Coronary heart disease is mainly restricted but not prohibited by the intake of animal fats. Because different foods have different nutrients, only food diversity can ensure nutritional balance. Hypertensive heart disease mainly restricts the intake of salt, you can eat squid with less salt and try to be as light as possible, which will not cause deterioration of the condition. In short, there are no absolute food taboos for heart disease, as long as you choose a reasonable cooking method.
