The temperature is getting warmer and the delicious "fruit season" is coming again. Nutrition experts point out that eating fruits should follow the principle of “fresh, seasonal, multiple, and appropriateâ€. In order to give full play to the health benefits of fruit, you have to avoid the following 8 misunderstandings. Biological pesticide
Misunderstanding 1: Eat if you want to eat. Fruits contain more organic acids and tannins, and some contain highly active proteases. The timing of eating is wrong and may cause irritation and injury to the stomach. Fu Jinru, chairman of the Tianjin Nutrition Society, said: "For example, bananas, high in magnesium, too much on an empty stomach, can cause imbalances in the proportion of magnesium and calcium in the blood, which may have a cardiovascular effect. In general, most fruits are suitable for 1 meal before meals. - Eat for about 2 hours."
Myth 2: Eat more without harm. Cai Donglian, chief physician of the Nutrition Department of Changhai Hospital affiliated to the Second Military Medical University, pointed out that it is appropriate to consume about 200 grams of fruit per day. Most fruits have high dietary fiber content, and eating too much can cause stomach pain and bloating. In addition, the elderly with gastrointestinal cold can not eat more citrus; people with poor stomach or constipation should eat less persimmons. Some people who eat pineapple can induce allergies, and those who are gastrointestinal and coagulopathy do not eat as well. Bananas are high in sugar and potassium, and those with high blood sugar and kidney dysfunction should eat less. Biological pesticide
Myth #3: Fruit can replace vegetables. Although the nutrition of fruits and vegetables is very similar, fruits cannot replace vegetables. For example, the vitamin C content of cabbage and spinach is about 10 times higher than that of apples, peaches and pears. If you want to meet the recommended amount of vitamin C for a day, you need to eat 5 kg of Fuji apple.
Myth 4: Fruit has the highest vitamin content. Vitamins are a big family with many members. Fruits may be rich in some of these ingredients, but they also have "short boards", such as fruits that do not contain fat-soluble vitamins, and most fruits have limited vitamin C content.
Misunderstanding 5: Fruit is a meal, beauty and beauty. Cai Donglian said that the protein, fat and calcium, iron and other content of fruit are less. If you take fruit for a long time, it will definitely cause insufficient intake of protein and lipids, resulting in malnutrition and anemia.
Myth 6: Eat more fruits to lose weight. Although the calorie of the fruit is lower than the rice by the unit weight, it is easy to eat because of its good taste. If it is not careful, the sugar intake will exceed the standard. This will not only lose weight, but even counterproductive.
Misunderstanding 7: Anti-pesticide peeled peel. The fruit skin and its subcutaneous parts are often the most nutritious parts, and it is a pity to throw them away. In fact, you don't have to worry too much about the bio-pesticide residue on the peel. China has explicitly banned the use of highly toxic pesticides in directly imported foods such as fruits and vegetables, and most of the fruits are eaten only a few days or even months after harvest, and the pesticides have basically been decomposed. Cai Donglian suggested that it can be washed repeatedly before eating fruit, or soaked in rice water for a while to remove residual substances on the surface.
Myth 8: Foreign fruits are more nutritious. "Foreign Fruit" has high transportation, packaging and storage costs, and the price is also high. In order to look good, such fruits may be treated with preservatives or waxed on the surface to keep the appearance bright and radiant, but the nutrients will gradually lose in transportation. Therefore, fruit is best to eat locally and seasonally.
