Patients can estimate the daily salt content with a spoon. Specifically, each teaspoon is equivalent to 5 grams of salt, each tablespoon is 15 grams of salt.
However, Dr. Phuong Dung emphasized, this total amount of salt includes natural salt available in food, salt used as a food preservative, seasoning salt used in food processing, and salt in sauces. .. Not only dry foods but also boiled noodles, vegetables, fruits… also contain a certain amount of natural salt.
