What diseases can a low-salt diet help prevent?

A low-salt diet can prevent cardiovascular diseases such as hypertension. A large number of scientific studies have proved that people with low-salt diet are less likely to suffer from hypertension, and people with high blood pressure after low-salt diet have better blood pressure control than those who do not eat low-salt diet. The Dietary Guidelines for China Residents suggest that each person should consume no more than 6 grams of salt every day. In addition to edible salt, we should also pay attention to "invisible salt" in daily life, such as bean paste, fish paste, shrimp paste, tomato sauce and other sauces, as well as snacks such as preserved plum, potato chips and pickles.

Tips for controlling salt

Dietary Guidelines for China Residents suggest that the salt intake should be less than 6 grams per day. Patients with hypertension should control their salt intake below 3 grams per day. Tip 1 (Take healthy people as an example): Use salt control tools (salt pot, salt spoon). When a person cooks, take salt with 2 grams of salt spoon, one spoon per meal, three spoonfuls a day; When two or more people are cooking, take salt with 6 grams of salt spoon, one spoon per person per day, several spoonfuls for several people, and put it into the salt-limiting tank. When cooking, sprinkle salt from the small hole in the salt-limiting cylinder and it will be used up in one day.

Tip 2: Eat low sodium salt. For patients with hypertension, it is recommended to use low sodium salt. The low sodium salt contains 65% sodium chloride, 25% potassium chloride, 10% magnesium chloride and magnesium sulfate. Use vinegar, pepper, pepper, onion, ginger, garlic and other condiments and rich vegetables to enhance the taste. When cooking, just put salt before cooking, and put salt before eating cold salad. Less salt can have obvious salty taste.

Timely supplement of potassium and calcium

The key to controlling salt is to control sodium intake. Supplementing potassium and calcium in time is beneficial to reduce sodium intake, thus lowering blood pressure. Potassium can replace excess sodium in the body to lower blood pressure. Foods rich in potassium include fresh green leafy vegetables, edible fungi and citrus fruits.

Calcium can increase urinary sodium excretion and reduce the adverse effect of sodium on blood pressure, thus helping to lower blood pressure. Clinically, it is found that about 50% patients with hypertension have a significant drop in blood pressure after eating high-calcium food. Foods rich in calcium include milk, bean products, kelp, seaweed, shrimp skin, sesame and so on.
