Which kinds of fish are beneficial to protect cardiovascular and cerebrovascular diseases? How to eat healthier?

For patients with cardiovascular and cerebrovascular diseases, we should always pay attention to diet. Maybe some friends have heard a suggestion: to eat meat, it is better to choose four legs than two, and two legs are better than those without legs. Legless fish is an aquatic food that many people like to eat. It is not only nutritious, rich in high-quality protein, but also low in fat. The taste is delicate, smooth and easy to digest.

In addition, fish are rich in vitamins and unsaturated fatty acids, which can counteract the effects of saturated fatty acids, reduce blood lipids, prevent platelet aggregation, and prevent thrombosis and cardiovascular and cerebrovascular diseases. Therefore, fish is called the most suitable meat for elderly patients and patients with cardiovascular and cerebrovascular diseases, especially deep-sea fish rich in omega-3 fatty acids. However, not all fish are suitable for patients with cardiovascular and cerebrovascular diseases. The following three kinds should pay special attention to eat less or not!

Patients with cardiovascular and cerebrovascular diseases eat more fish for their health, but it is best not to touch three kinds of fish!

(1) Fish with Chinese sauerkraut

Pickled fish is also called salted fish. Many families preserve fish with salt, not only fish, pork, beef, radish and so on. This kind of meat is rich in salt. If patients with hypertension eat too much, it will increase the intake of sodium salt, increase the amount of drinking water, increase the blood volume, increase the burden on the kidneys, and lead to an increase in blood pressure and heart load. Moreover, salted fish contains carcinogenic nitrosamines, which will increase the risk of digestive tract cancer and nasopharyngeal carcinoma.

(1) Fried smoked fish

Besides curing, people also like to cook fish by frying, smoking and roasting, so that fish can be preserved for a longer time. However, the foods made by these cooking methods often add heavier oils and some heavy seasonings will also increase the salt intake. Moreover, studies have shown that the prevalence of gastrointestinal intraepithelial tumors will increase among people who like to eat fried and smoked meals [2]. Therefore, for patients with cardiovascular and cerebrovascular diseases, it is best not to touch such fish, but to eat fresh fish.

(2) Raw fish

Some friends may think that fried and pickled foods are not edible, so can raw fish or sashimi be eaten? After all, it is fresh fish. However, raw and undercooked fish, even marine fish, are at risk of parasitic infection, and some parasites even enter the brain, leading to cerebral infarction. Even in Japan, where raw fish are prevalent, parasitic infections are often reported every year. Moreover, people think that mustard, soy sauce and wine can't kill parasites in fish, and the best way is to cook them.

abstract

Although fish is good, it is better to eat fresh and cooked fish if you want to enjoy it healthily. In particular, patients with cardiovascular and cerebrovascular diseases should avoid eating some pickled, fried or smoked foods, and so should fish.
