Introduction: Be careful when eating only fruit, as you may develop diseases common in overweight people, such as high blood sugar or high blood lipids. This is because fruit itself is rich in sugars, and if you consume too many sugary foods and get little exercise, you can develop problems with high blood sugar or high blood lipids.
1. Eating too many oranges can turn your whole body yellow
Oranges contain carotene. Due to the large intake of citrus fruits (eating more than 1 to 2 jin per day) or carrots in a short period of time, the liver cannot metabolize the carotene into vitamin A in a timely manner. This causes a sharp increase in the carotene content in the blood, leading to the yellow pigment depositing in the skin and tissues, which in turn causes carotenemia and makes the skin turn yellow.
2. Obese people should not eat large amounts of fruit
Eating only fruit, be careful of developing diseases common in overweight people, such as high blood sugar or high blood lipids. This is because fruit itself is rich in sugars, and if you consume too many sugary foods and get little exercise, you can develop problems with high blood sugar or high blood lipids. This is something that obese people, patients with diabetes, hyperlipidemia, and fatty liver, as well as women who lose weight by eating only fruit, and pregnant women, should pay special attention to.
3. Fruit is not suitable for drinking as juice
Nowadays, more and more families are buying juicers, thinking that drinking fresh fruit juice is both delicious and convenient. However, nutrition experts remind that except for people with bad teeth, fruit should not be drunk as juice, as eating it directly is more nutritious.
This is because drinking fruit juice reduces people's intake of the fiber rich in fruit. This fiber has health benefits such as preventing and reducing diabetes, cardiovascular diseases, etc., and can also effectively stimulate gastrointestinal motility and promote bowel movements.
In addition, eating fruit directly can easily produce a feeling of fullness, while drinking juice can unknowingly consume too many calories and sugar, increasing the chance of getting sick.
4. Buy less pre-cut fruit
Fruit is a major source of vitamin C, which is easily oxidized in the air. High temperatures and sunlight can cause it to be lost. Pre-peeled and cut fresh fruit may have reduced nutritional value. The British Consumers Association conducted a study on the vitamin C content of pre-packaged cut fruits sold in supermarkets and found that in 13 samples, 4 had vitamin C content half lower than that recorded in reference books.
5. Improperly handled pre-cut fruit is easily contaminated by bacteria
The surface of fruit is easily contaminated by pollutants, chemicals, animal excrement, or bacteria like Salmonella. If fresh fruit has not been disinfected, its surface may have Salmonella. When a knife is used to cut fresh fruit that has not been washed, bacteria from the contaminated peel can be transferred to the edible part by the knife. If cut fruit is left at room temperature for too long, bacteria will multiply.
6. Frozen fruit can produce toxic substances
Nutrition experts remind that after being frozen, fruit is more likely to produce nitrites. Consuming excessive nitrites can cause symptoms such as headache, dizziness, nausea, and vomiting.
It is crucial for customers to learn how to identify whether fruit has been frozen. After oranges and tangerines are frozen, the oil from the peel seeps into the pulp, making the pulp easy to become bitter. The surface of frozen fruit generally turns black.
7. Eating unripe bananas can worsen constipation
Bananas are rich in dietary fiber, a large part of which is not digested and absorbed, but it can increase the volume of feces and promote intestinal peristalsis.
At the same time, bananas have a sugar content of over 15% and contain a large amount of water-soluble plant fiber, which can cause hyperosmotic secretion of gastrointestinal fluids, thus drawing water to the solid part and making the feces soft and easy to excrete. However, these effects are only present in ripe bananas. Unripe bananas may have the opposite effect. They contain more tannic acid, which is difficult to dissolve and has an astringent effect on the digestive tract, inhibiting the secretion and motility of gastrointestinal fluids. If consumed in excess, it can cause or worsen constipation.
8. Be aware of allergies when eating mangoes
Mangoes contain large amounts of fruit acids, amino acids, proteins, etc. These substances contain more irritating substances. When they come into contact with human skin, they can cause allergies. In severe cases, redness, swelling, and pain may occur. However, not everyone will have an allergic reaction to eating mangoes, and even if they do, the reactions vary from person to person. Some people react on the same day they eat it, while others may not show symptoms until two or three days later.
9. Synthetic vitamin C cannot replace fruit
The natural vitamin C found in fruits and vegetables has an undeniable advantage over synthetic vitamin C: in many fruits and vegetables, vitamin C exists in a combined state with two substances, vitamin C and vitamin P. In the body, vitamin P helps vitamin C to function. Synthetic vitamin C, on the other hand, is a pure drug preparation, and its effect is far inferior to natural vitamin C. In addition, taking vitamin C tablets often involves a large dosage, and long-term use can produce a large amount of oxalic acid in the body, which becomes the material basis for kidney stones. The vitamin C in fruits and vegetables does not cause oxalic acid in the urine to become too high.
10. Avoid eating fruit immediately after a meal
Eating fruit immediately after a meal will not help digestion; on the contrary, it can cause bloating and constipation. Therefore, it is best to eat fruit 2 hours after a meal or 1 hour before a meal.
11. Avoid not rinsing your mouth after eating fruit
Some fruits contain various fermentable sugars that are highly corrosive to teeth. If you do not rinse your mouth after eating, fruit residue in the mouth can easily cause cavities.
12. Avoid eating too much fruit
Excessive consumption of fruit can lead to copper deficiency in the body, which in turn can increase cholesterol in the blood and cause coronary heart disease. Therefore, it is not advisable to eat too much fruit in a short period of time.
13. Eating fruit that has started to rot
And eating fruits such as strawberries, mulberries, and sliced watermelon that are not protected from dust and flies and are not thoroughly washed and disinfected can easily cause digestive tract infectious diseases such as dysentery, typhoid, and acute gastroenteritis.
14. Avoid using alcohol to disinfect fruit
Although alcohol can kill bacteria on the surface of fruit, it can change the color, aroma, and taste of the fruit. Alcohol reacting with the acids in fruit can reduce its nutritional value.
15. Avoid eating raw fruit without peeling it
Some people believe that the vitamin content in the peel is higher than in the pulp, so they eat the fruit with the peel. However, when fruits have pests and diseases, pesticides are often sprayed to kill them. The pesticides can penetrate and remain in the wax of the peel, so the pesticide residue in the peel is much higher than in the pulp.
16. Avoid using a kitchen knife to peel fruit
Kitchen knives often come into contact with meat, fish, and vegetables, which can bring parasites or parasite eggs to the fruit, causing people to get parasitic diseases. Especially, the rust on the kitchen knife and the tannic acid in the apple can react chemically, making the apple's color, aroma, and taste worse.
17. Most fruits are cool-natured and are more suitable for eating in the afternoon
Some people are used to eating fruit as soon as they get up. In fact, most fruits are cool foods, and eating them right after getting up can irritate the stomach. It is best to eat fruit in the afternoon around 3 or 4 o'clock, which is beneficial for the absorption and utilization of nutrients.
18. Imported fruits are not necessarily safer than local fruits
Many consumers believe that "imported fruits" are safer. In fact, China's fruit quality and safety mechanism is relatively sound. Imported fruits travel a long way, and more preservatives and preservatives are inevitably used for preservation and storage, making them relatively more dangerous than local fruits.
19. Do not blindly pursue the appearance of fruit
Many people think that brightly colored, perfectly shaped, and large-sized fruits are good fruits, but this may lead them into the trap of unscrupulous vendors who use illegal methods to forge the appearance of the fruit.
20. Fruit is high in calories and cannot replace vegetables
Fruits and vegetables are indispensable and cannot replace each other. Although they are both plants, their compositions are quite different. Some minerals in vegetables are not found in fruits. If you only eat fruit, you will lack nutrients such as folic acid. Moreover, fruit has calories, and eating too much fruit may lead to obesity, which is especially not good for diabetics. In addition, eating too few vegetables can lead to a lack of fiber, which may cause constipation. Fruit is mainly eaten raw and has a high water content.
