What is the difference in nutrition between tomatoes and cherry tomatoes?
The nutritional value of cherry tomatoes is better than that of ordinary tomatoes.
Cherry tomatoes, also known as grape tomatoes and cherry tomatoes, contain all the nutrients of tomatoes, and their vitamin content is 1.7 times that of ordinary tomatoes. "
Cherry tomatoes contain special substances, such as grains, sugar and lycopene. These substances can promote the growth and development of the human body, especially the growth and development of children, increase the body's resistance and delay the aging of the human body. In addition, lycopene can protect the human body from carcinogenic toxins in cigarettes and automobile exhaust, and can improve the sun protection function of the human body. In recent years, scientists in the United States and Germany have found that lycopene in tomato products can not only prevent cancer, especially prostate cancer, but also treat prostate cancer.
Eating tomatoes raw equals smoking? Nicotine is confirmed in vegetables. Experts believe that the content is very small and does not pose a threat to health. Vegetables contain nicotine. Eating raw vegetables is equivalent to passive smoking? Yesterday, a news spread quickly on the Internet, which attracted people's attention. According to the report, scientists have found nicotine content in some vegetables, so it is best not to eat raw vegetables such as tomatoes. The authoritative experts on food and vegetables in Nanjing think that there is no need to be nervous, because the nicotine content in vegetables is too small to pose a threat to the human body.
According to online news, American scientists have found through long-term research that vegetables commonly used by people, such as tomatoes, potatoes, eggplant and cauliflower, all contain different amounts of nicotine. If these vegetables are eaten raw without cooking, more nicotine will enter the human body, which is similar to passive smoking in smog. Zhou Dabiao, director of Nanjing Institute of Vegetable Science, said that so far, I have never heard of the statement that vegetables contain nicotine, but some vegetables, such as lentils, do have an impact on health if they are not cooked enough because they contain alkaline substances.
Associate Professor Yu Zhifen of Nanjing Agricultural University told reporters that vegetables are not all beneficial and harmless. In addition to lentils containing some harmful substances, some vegetables may even cause allergic diseases and metabolic diseases. Scientific research has found that nicotine does exist in vegetables commonly used by people, such as tomatoes, potatoes, eggplant and cauliflower. However, scientists have found that the nicotine content in tomatoes is very small and can only be measured in micrograms, so it can be ignored. Therefore, under normal circumstances, eating vegetables will not affect the human body, and there is absolutely no need for the public to worry about it.

Compared with ordinary vegetables, tomatoes are rich in natural antioxidants, and besides vitamin C, they also contain lycopene. Vitamin c is familiar to everyone. It can prevent colds and treat scurvy. Lycopene is a natural pigment that turns tomatoes red. Its function in human body is similar to carotene, and it is a strong antioxidant. Experiments show that lycopene has good anti-atherosclerosis, anti-oxidative damage and vascular endothelial protection functions. The higher the lycopene content in human plasma, the lower the incidence of coronary heart disease. Lycopene also has a good anti-cancer effect, and its strong antioxidant activity can eliminate free radicals that promote the growth of cancer cells and prevent the proliferation of cancer cells. It was found that the content of lycopene in serum of women with hysteromyoma and cervical cancer was lower than that of normal women. When the content of lycopene in serum is high, the probability of human suffering from gastric cancer and digestive tract cancer is small.
The study also found that people who eat processed tomatoes can increase the concentration of antioxidants such as lycopene in their blood compared with those who eat raw tomatoes. This is because high temperature destroys the cell wall of tomato cells, thus increasing the release of antioxidants such as lycopene. In addition, vegetable oils such as peanut oil and salad oil are often used in the cooking process of tomatoes, which will help tomatoes naturally release fat-soluble antioxidants such as lycopene and give full play to their antioxidant effects. Of course, everything has advantages and disadvantages. After heating, vitamin C in tomatoes will be lost, but the content of antioxidants such as lycopene in tomatoes will increase significantly. Therefore, the overall nutritional value of cooked tomatoes is higher than that of raw tomatoes. In addition, tomato skin contains a lot of lycopene, so it is best not to discard the skin when eating.
For patients with vitamin C deficiency, eating tomatoes raw is also a good way to supplement vitamin C, but immature green tomatoes contain toxins and are not suitable for eating. In addition, some tomatoes show prominent tops due to the use of plant hormones in the growth process, and this tomato is also not suitable for eating.
