Nutritional value of purple tomatoes

1. Tomatoes contain vitamins and mineral elements that have protective effects on the cardiovascular system and can reduce the incidence of heart disease.

2. Lycopene has a unique antioxidant capacity, which can remove free radicals, protect cells, prevent DNA and genes from being damaged, and prevent the progression of cancer. In addition to preventing prostate cancer, tomatoes can also effectively reduce the risk of pancreatic cancer, colorectal cancer, laryngeal cancer, oral cancer, lung cancer, breast cancer and other cancers.

It has a good auxiliary therapeutic effect on patients with hypertension and kidney disease. Eating more tomatoes has anti-aging effects and keeps the skin white.

3. Antifungal. Tomatine has antifungal effects. It can inhibit certain fungi that are pathogenic to plants or humans; but its effect on bacteria is very poor. Tomatine, which was originally extracted from tomatoes, is mixed with rutin, especially its aglycone - quercetin; quercetin can antagonize the antibacterial effect of tomatine, so the antifungal effect of tomatine is not strong.

4. Treat ulcers. Patients with mild peptic ulcers can mix half a cup of purple tomato and potato juice and drink it once in the morning and evening every day for 10 consecutive times, and the ulcers can be cured.

Medicinal value of purple tomatoes

The ingredient in tomatoes that is helpful to the human body is lycopene, which is the pigment that makes tomatoes red. Lycopene is a type of carotenoid. Another well-known carotenoid is carotene, which is one of the main nutrients in carrots.

The most striking function of lycopene is its antioxidant effect. According to Mr. Inao, director of the Vegetable Research Institute of Kagome Co., Ltd., human activities produce reactive oxygen species, which shortens lifespan. For example, professional athletes who exercise regularly have a lifespan that is six to seven years shorter than those who do not exercise regularly. One of the main reasons is the effect of excessive reactive oxygen species on the human body. Compared with ordinary oxygen, reactive oxygen species have a stronger oxidizing ability on objects. Even in daily life, 2-3% of the oxygen that enters the body will be converted into reactive oxygen species.

Normally, active oxygen attacks foreign matter such as bacteria that invade the body, promotes enzyme reactions in the body, and is indispensable to our body. However, the reason why active oxygen is now attracting so much attention is that we are in such a big background: many modern life factors such as mental stress, smoking, drinking, exhaust gas, ultraviolet rays, electromagnetic waves, radiation, etc. have led to the continuous increase of active oxygen. Active oxygen has adverse effects in the human body and will eventually lead to various cancers, heart and brain diseases, physical and mental diseases and other lifestyle diseases.

Side effects and contraindications of purple tomatoes

1. Eating tomatoes on an empty stomach can cause stomach bloating

Tomatoes contain a large amount of soluble astringents and other ingredients, which react with stomach acid and condense into insoluble lumps. These lumps may block the pyloric outlet of the stomach and cause uncomfortable symptoms such as gastrointestinal bloating and pain.

2. Eating tomatoes may cause poisoning

The reason is: According to him, tomatoes contain alkaloid glycosides (solanine) in the form of needle-shaped crystals, which are very stable to alkalinity but can be hydrolyzed by acid. Therefore, eating unripe green tomatoes often makes people feel uncomfortable, with a bitter taste in the mouth at the mildest, and even poisoning in severe cases. Especially when green tomatoes begin to rot, the solanine in them will be destroyed. When green tomatoes turn red, they no longer contain solanine.

3. Long cooking time is not nutritious

After long-term heating and cooking, they lose their original nutrition and taste. Eating spoiled tomatoes can cause food poisoning.

4. Be careful when taking with neostigmine or galantamine

Recommendation: Follow doctor's advice

5. Eating with cucumber is not nutritious

Many restaurants have a dish called "Big Harvest", which is a combination of carrots, lettuce, tomatoes, cucumbers and other vegetables eaten raw with sauce. Eating vegetables raw is indeed conducive to the preservation of nutrients, but with cucumbers in this dish, its nutritional value is greatly reduced.

6. Taking it with anticoagulants can cause subcutaneous bleeding

Tomatoes contain more vitamin K. Vitamin K: Its main function is to catalyze the synthesis of prothrombin and thrombin in the liver. The minimum requirement for dogs is 30ug/kg body weight. When vitamin K is insufficient, the synthesis of prothrombin is restricted, which prolongs the coagulation time and causes subcutaneous and muscle bleeding.
