Dark fruits and vegetables (such as red, yellow, green, black, etc. ) are rich in nutritional value, and attention should be paid to "color inspection" when choosing.
Take tomato as an example, it tastes sweet and sour, slightly cold, and is extremely suitable for patients with poor appetite and hot constitution. From the point of view of diet, the nutritional characteristics of red tomatoes are also the best among all ingredients.
The content of vitamin C in tomatoes is high, and beta carotene can also be converted into vitamin A in the body, which is beneficial to the improvement of patients with dry eye. Compared with people who eat too much meat and snacks and often stay up late, eating tomatoes rich in dietary fiber can also play a role in detoxification and laxative.
It is probably every woman's dream to have smooth, delicate and fair skin. Then, an indispensable ingredient on the dining table should be carrots that are always "unpopular". Like tomatoes, carrots have a high content of beta carotene, which can be converted into vitamin A by itself after entering the human body. In addition to enhancing immunity, it can also improve eyesight and liver, which has a great effect on improving "acne muscle" and goose skin. In addition, because carrots are good for bone development, children in the growth and development stage should eat more.
Besides carrots, other famous beauty products include lemons and kiwis. Both of them are rich in vitamin C, which plays a great role in resisting oxidation and delaying aging. Among them, citric acid in lemon helps to resist free radicals, so it can play a role in whitening and rejuvenating skin.
It should be noted that the sweetness of lemon and kiwi fruit is inversely proportional to the vitamin C content, that is, the sweeter the taste, the less the vitamin C content. In addition, citrate in lemon can also soften kidney calculi, which is of great significance to prevent the formation of stones.
Fruits and vegetables are simply a treasure house of nutrition and health care, and they are also the best gifts given to us by nature. I hope everyone can fall in love with the natural flavor of fruits and vegetables and eat good food healthily! But the serious problem before us now is pesticide residue, which is too harmful to the body!
The ranking of pesticide residues in vegetables scares everyone. Young spinach dare not eat, fresh cucumbers dare not touch, and even beloved tomatoes are on the black list! Let's see how to choose and eat fruits and vegetables to meet the needs of summer.
According to the statistics of Agricultural Products Monitoring Center, the qualified rate of pesticide residues from low to high is beans, eggplant, Chinese cabbage, green leafy vegetables, taro and potato root vegetables, onion and garlic, melons and edible fungi.
In terms of plant characteristics, there are many pesticide residues in green leafy vegetables and low pesticide residues in Chinese cabbage farmers.
Because their leaves are soft and moist, insects like to eat them, so they spray more pesticides. Artemisia stem, chrysanthemum, coriander, etc. It has a strong fragrance and is a natural insect repellent.
Because I love eating insects, I am often sprayed with strong pesticides, some of which are highly toxic and easy to remain; Cucumber and tomato have many fungicides, which are easy to get sick when the humidity is high, especially fungicides. Compared with pesticides, fungicides are less harmful to human body.
Seasonal, pesticide residues are low in winter and high in spring, summer and autumn.
Because the temperature difference between indoor and outdoor is relatively large in winter, the air circulation is not very good, which is not suitable for pest reproduction, so the pesticide is used less and the pesticide residue is low.
The Ministry of Agriculture once tested vegetable samples in Beijing, and found that May and June 165438+ 10 were the periods with high detection frequency.
The test results in Hangzhou showed that April and 10 were the highest pesticide residues in vegetables in Hangzhou.
From the planting location, there are few pesticide residues in greenhouse fruits and vegetables.
Because physical methods such as gas net can be used to control pests in greenhouse, less pesticides are used.
Compared with greenhouse vegetables, open-field vegetables look natural, but they use more pesticides than greenhouse vegetables.
"Have a look" means not to buy anything with abnormal color when buying food. Fresh vegetables are not as bright as possible. This kind of vegetables is likely to use plant hormones, ripening agents and so on.
Don't buy vegetables with abnormal shapes, stale vegetables have abnormal shapes such as wilting, dryness, damage, pathological distortion, etc. Some vegetables will be deformed by the use of hormones.
"Wen Er" refers to vegetables that are eager to go on the market after spraying pesticides for a short time. This kind of vegetables generally have the special smell of pesticides, that is, the smell of garlic, especially the vegetables contaminated by spraying organophosphorus pesticides. This tastes stronger. When you buy food, you might as well open it and smell it.
"Three touches" means touching the skins of vegetables and fruits. It is best not to buy those that are too smooth and slippery. Nowadays, many pesticides are added with gum or starch to resist rain erosion, and the surfaces of fruits and vegetables will be extremely smooth after spraying such pesticides.
If you want to eat healthy, vegetables and fruits are essential, but pesticide residues do not increase health risks and plant bombs on your body! So be sure to pay attention to the cleaning of vegetables and fruits. Ordinary cleaning methods cannot completely remove pesticide residues. Choosing a professional food purifier is the choice of many families who pay attention to the quality of life.
