Several advantages of natural food 1 British nutritionists said in their book "Nutrition Bible" that when choosing food, we should try our best to meet three characteristics: natural, fresh and complete. The first point is that food should be natural. Natural food refers to the food that grows naturally, is unprocessed or processed only in a small amount in the later stage, and does not contain various chemical additives such as preservatives, emulsifiers and artificial colors artificially added during the processing. In contrast, we can see jelly, ice cream, preserved fruit, juice drinks, soda, candy, biscuits, instant noodles and other foods at the food counter in the supermarket. Although these processed foods and fast food products are convenient to eat and attractive in taste, they are often eaten by many fast-paced people, but they are accompanied by high energy, a large number of food additives, and lack of vitamins, minerals and dietary fiber. Long-term consumption is eroding our health! So, what's the difference between natural food and them?
First of all, natural food has a low degree of processing and less nutritional damage. For the simplest example, fresh apples, rich in potassium, vitamins, malic acid, pectin and apple polyphenols, are very healthy foods, and even many institutions have selected them as one of the top ten healthy foods. After processed into "preserved fruit", a snack that many children like to eat, although the taste is very attractive, apple polyphenols and vitamin C in it are lost, minerals and malic acid are inevitably lost, and the nutritional value is greatly reduced.
Secondly, natural food will not add food additives. If you carefully look at the packaging of processed foods in the supermarket food area, it is difficult to find out which foods do not contain food additives. Although moderate intake of food additives is considered safe, and only food additives that have passed the safety test can be used in food, we still do not advocate eating too much processed food and eating too much food additives. For example, synthetic pigments are often used as food additives and are widely used in ice cream, soda, candy, fruit juice drinks and cream cakes.
Third, natural food is rich in bioactive substances. Many scientists are studying the longevity areas in the world, trying to find out the food secrets of these longevity areas. It turns out that some people who live a long life like to drink yogurt, some like to eat broccoli, some like to eat garlic, and some eat corn and sweet potatoes every day. In terms of diet, it seems that I can't find much sex. But at least one thing is certain. People in these longevity areas like natural food, and they usually have the habit of eating some natural food for a long time! Besides protein, fat, carbohydrates, vitamins, minerals and dietary fiber, you can also find antioxidants such as polyphenols, polysaccharides, saponins, flavonoids and anthocyanins in natural foods. These special ingredients often have special physiological functions, such as preventing excessive free radical reactions in the body, antioxidation, preventing cardiovascular diseases, etc., which will greatly promote our health!
People advocate all kinds of natural foods. This is not only a kind of consumption fashion, but also represents people's consumption psychology. However, natural food is by no means equal to safe and hygienic green food. Some natural foods contain some harmful ingredients-harmful bioactive substances. The so-called bioactive substances refer to those substances that can cause various biological effects after interacting with the body. These substances can be produced by the human body itself or can enter the human body from the outside. Many natural foods contain such substances, some of which are beneficial to human body and some are harmful to human body. Therefore, when choosing food, we should master the correct understanding method.
In China, it is generally believed that what is natural is good, but the fact is that foods or additives processed with natural resources are not necessarily safe and hygienic green foods. Because many natural plants have some harmful ingredients more or less. Due to the influence of polluted soil, water, air and pesticides, some harmful components will remain in natural plants. Moreover, if natural plants are not strictly controlled in the process of planting, harvesting, storage and production, it will be more difficult to ensure their edible safety. Therefore, it is wrong to hold the understanding that food is "naturally safe". The reason for holding this old concept of food choice may come from China's traditional dietary concept for thousands of years.
Several benefits of natural food 2 In the field of food, as we all know, the old-fashioned topics are genetically modified, pesticides, herbicides, food additives, hormones, expansion agents, antibiotics, veterinary drugs, plasticizers and so on. The actual hormones and herbicides can be attributed to pesticides, and these pollutants are familiar as long as they are slightly senior foodies.
The reasons for encouraging people to eat natural ingredients are:
1. Organic farms use old seeds with a long history, that is, non-transgenic seeds for farming. Some of these seeds were selected, domesticated and cultivated by farmers in China for thousands of years, dynasties and generations. It embodies the wisdom of the Chinese nation from the era of the Yellow Emperor and the evolutionary power of nature. It is not only sacred, but also priceless. It is related to the prosperity of the Chinese nation. People's choice of natural ingredients will directly promote the development of organic farms, thus directly promoting the protection of old seeds and giving the strongest support to the protection and inheritance of old seeds.
2. Organic farms are forbidden to use any pesticides that will destroy the balance of nature itself, so it has very good biodiversity, including plants, animals and microorganisms. Therefore, the value of organic components includes biodiversity and ecological balance. Therefore, in the orchard of organic agriculture, we can see vast weeds and vibrant nature.
3. Delicious, which restores the real taste of food. Organic agriculture advocates maintaining the natural ingredients of products, so it can maintain the original taste and nutrients of food and provide original enjoyment. The moisture content of organic vegetables is much lower than that of ordinary vegetables, but the sweetness is higher, so organic vegetables taste more delicious. Organic food tastes firm, crisp and juicy, and tastes sweet, without the bitter taste, chemical taste, astringent taste, light taste and strange taste brought by adding fertilizers and pesticides.
