An apple a day, the doctor away from me, often eat fruit benefits, but incorrect habits not only can not achieve the purpose of health care, but will bring a variety of diseases. So I hope you must pay attention to oh. 1, immediately after the meal to eat fruit immediately after eating fruit, not only will not help digestion, but will cause flatulence and constipation. Therefore, it is appropriate to eat fruit 2 hours after meals or 1 hour before meals. 2, eating too much fruit Excessive consumption of fruit will make the body lack of copper, which will lead to increased cholesterol in the blood, causing coronary heart disease, so it is not appropriate to eat too much fruit in a short period of time. 3, eat rotten fruit consumption began to rot fruit, as well as no dust, fly-proof equipment and not thoroughly washed and disinfected fruit, such as strawberries, mulberries, cut pieces of watermelon, etc., prone to dysentery, typhoid, acute gastroenteritis and other gastrointestinal infections. 4, the fruit with alcohol disinfection alcohol can kill the fruit surface bacteria, but will cause the fruit color, fragrance, taste changes, alcohol and the role of acid in the fruit, will reduce the nutritional value of the fruit. 5, raw fruit without peeling Some people think that the vitamin content of the peel is higher than the flesh, and therefore eat fruit with the peel. I do not know, the fruit pest, often with pesticide spraying, pesticides will penetrate and remain in the peel wax, so the pesticide residues in the peel than the pulp is much higher. 6, with a kitchen knife to peel fruit because the kitchen knife often contact meat, fish, vegetables, will bring parasites or parasitic eggs to the fruit, so that people are infected with parasitic diseases. Especially the rust on the kitchen knife and the tannic acid contained in the apple will start a chemical reaction, so that the color, aroma and taste of the apple deteriorate. 7, get up and eat fruit Some people are used to get up and eat fruit. In fact, most of the fruit is cold food, just when you get up to eat will stimulate the stomach and intestines. It is best to eat fruit at three or four o’clock in the afternoon, which is conducive to the absorption and utilization of nutrients. 8, obese people do not eat a lot of fruit only eat fruit, beware of fat people prone to diseases such as blood sugar or blood lipids. Because the fruit itself is rich in sugar, if you eat too much sugar food, and less exercise, will happen blood sugar or blood lipids too high. This point, obesity, diabetes, hyperlipidemia and fatty liver patients, and only eat fruit meals to lose weight, as well as pregnant women should pay special attention. 9, the fruit is frozen will produce toxic substances Nutrition experts warned that the fruit is frozen, more likely to produce nitrite, and the consumption of excessive nitrite, will cause headaches, dizziness, nausea, vomiting and other symptoms. Customers learn to identify whether the fruit is frozen is critical. Oranges, oranges frozen, the skin of the oil seeped into the flesh, the flesh is easy to bitter. The surface of the frozen fruit is generally black. 10, eat unripe bananas will lead to constipation aggravated Bananas are rich in dietary fiber, a large part of which will not be digested and absorbed, but can make the volume of feces increased, and promote intestinal peristalsis. At the same time, bananas contain more than 15% sugar and a large amount of water-soluble plant fiber, which can cause the secretion of hyperosmolar gastrointestinal fluid, thus absorbing water into the solid part and making the stool soft and easy to pass. However, these effects are only ripe bananas have, not ripe bananas may play a counterproductive, it contains more tannic acid, more difficult to dissolve, and for the digestive tract has an astringent effect, will inhibit the secretion of gastrointestinal fluid and inhibit its peristalsis, such as excessive intake will cause constipation or aggravate the constipation condition. 11, fruit can not be a staple food Now there are many women simply take fruit as a staple food to lose weight and beauty. So, this practice is right or wrong? From a nutritional point of view, the body needs carbohydrates, minerals, proteins and other nutrients. If you live on “fruit” for a long time, it will have a negative impact on the endocrine, digestive and immune systems of the human body. In addition, lunch eating fruit, the afternoon will feel hungry, to dinner really can not stay up, inevitably eat an excessive amount, so it is difficult to obtain weight loss, and even more obese. 12, some fruits should not be eaten on an empty stomach The fruits that should not be eaten on an empty stomach are bananas, persimmons, oranges, lychees, sugar cane. In the peak season of melons and fruits, for people of different physiques, eating fruit is also very delicate.

These fruits include lychee, longan, pomegranate, cherry, coconut, durian, apricot and so on. On the contrary, people with real hot body have a high metabolism and generate more heat, so they often have a flushed face and dry mouth, so they should eat more cool fruits such as melon, watermelon, pear, banana, mango, cucumber and tomato. And calm fruits such as grapes, pineapples, apples, pears, oranges, mangoes, plums, etc., can be eaten by people with either a cold or a hot body.
