Tomato is a low-fat and low-calorie vegetable, which is suitable for obese and hypertensive patients. 100g tomato juice contains calories 19, and tomato is high in dietary fiber, which helps to prevent constipation and improve satiety. Tomatoes are sweet and rich in many beneficial substances. Tomatoes contain many beneficial ingredients necessary for human body, such as calcium, magnesium, zinc, iron, phosphorus, potassium, selenium and so on, especially potassium. 100g tomato contains potassium 163mg, and 100g tomato only contains 5mg sodium ion, which is a typical "high sodium".
If we eat too much "heavy taste", the intake of salt is high and the intake of sodium ions exceeds the standard (the main component of salt is sodium chloride), it will cause water and sodium to stay in the body. At this time, the extravascular osmotic pressure will increase, compressing blood vessels and aggravating hypertension. The intake of high-potassium food will help to expel potassium ions combined with sodium ions and help to smoothly regulate extravascular osmotic pressure. Tomatoes are also rich in vitamins. For example, 100g tomatoes contain 19mg vitamin C, 92ug vitamin A and 0.57mg vitamin E, as well as vitamin B 1 and B2.
Tomatoes also contain a special ingredient-lycopene, which is an antioxidant. It can resist free radicals and prevent aging. Its antioxidant capacity is more than 30 times higher than that of vitamin E, and it also has a potential role in preventing prostate diseases. Some friends care whether tomatoes are eaten raw or cooked. In fact, tomatoes can be eaten raw or cooked. Eating raw tomatoes can retain more minerals and vitamins, while eating cooked tomatoes can better stimulate the absorption rate of lycopene. We can eat alternately, don't worry too much.
