From & lt; Poison & quot; To delicious

tomato is loved by people all over the world, but this kind of vegetable and fruit originated in Peru was suspected to be poisonous in the early years because of its bright color, so it was called & lt; Wolf peach;. In the 16th century, a Duke of England brought tomatoes to Europe, but they were only used as ornaments. Later, a painter risked his life to try them. He found that they were non-toxic and delicious. Since then, tomatoes have been on the table. Tomato was introduced into China in Ming Dynasty; Fan & quot; At that time, it was called & quot; Persimmon & quot;, Botanists later found that it is the same as eggplant, belonging to Solanaceae, also known as tomato. According to the introduction of foreign organic planting websites, there are four kinds of tomatoes: conventional tomato, cherry tomato, shrub tomato and steak tomato. Most of the common tomato species on the market are conventional tomato and cherry tomato, or both of them are cultivated.

the effect of tomato on health has been studied continuously at home and abroad. In the above study, the research team will bad cholesterol value 120 ~ 160 mg / dl of healthy < a (a) (a) (a) (a) (a) (a) (b) (a) (b) (b) (a) (b) (a) (b) (b) (a) (b) (a) (b) (b) (a) (b) (b) (b) (b) (b) (b) (b) (c) (b) (c) (b) (c) (c) (c) (C) (c) (c) (c) (c) (c) (c) (c) (c) (c) (c) (c) (c) (c) (k) (c) (c) (c) (, The vitamin C content of tomato per 100 grams is about 5 times that of apple.

lycopene is the main antioxidant component in tomato. Some clinical biochemical scientists fed lycopene to experimental mice, and the dose was equal to the recommended amount of human body. The results showed that the bone mineral density of experimental mice increased significantly, and the content of estrogen and other sex hormones also increased.

health benefits can be obtained by taking 5-10 mg of lycopene per person per day. The lycopene content of different kinds of tomatoes per 100 grams ranged from 0.8 mg to 4.2 mg. If calculated according to the median value of 2 mg, three medium-sized tomatoes per day could meet the demand. According to the dietary guidelines for Chinese residents (2016), the recommended intake of 300-500 grams of vegetables, Xu Shufang suggested that the recommended intake of Eggplant and melon, including tomatoes, should be about 150 grams.

there are many kinds of tomatoes, and different colors of tomatoes have different nutritional components. The American Society of horticulture has explored the influence of color differences on the nutritional value of tomatoes: red tomatoes are rich in lycopene; Orange tomato is rich in tocopherol, it is an antioxidant, which is beneficial to prevent eczema, psoriasis and other skin diseases; Yellow tomato usually has high content of polyphenols, which is beneficial to reduce cholesterol and blood pressure. Different tomatoes have different nutrients, but the researchers said that no matter which kind of tomato is conducive to improving the overall health index, so the selection should not be limited to a certain color, but should be diversified as far as possible.

Tomato products do not choose additives

many people have questions: is it better to eat tomatoes raw or to cook? Are tomato products such as ketchup also beneficial?

tomato sweet with some acid, raw not only appetizer, but also can put vitamins, dietary fiber and other nutrients in the body, but lycopene, carotene and other fat soluble nutrients, need to be mixed with oil in order to better absorb. Therefore, the tomato into the pot, add a small amount of oil fried, is conducive to the absorption of lycopene and carotene. In this case, the loss of vitamin C is also very small, and the content of nutrients such as dietary fiber and minerals that are not affected by temperature will not change. Therefore, tomatoes can be eaten raw or cooked. In order to better absorb lycopene, carotene and other nutrients, cooked food can better meet the demand, but pay attention to the amount of oil added must be less, a small spoon is enough.

However, it should be noted that when buying bottled tomato juice in the supermarket, you should carefully observe the ingredients list. Many of them add sugar, salt and other ingredients on the basis of tomato juice. This kind of drink is almost the same as a sweet drink.
