Do you have to eat more fruits and vegetables?
Although there are problems with pesticide residues in fruits and vegetables, the U.S. government and nutrition experts still reach a consensus that the health benefits of fruits and vegetables are greater than those of pesticide residues. If they are eaten properly, such as vegetables are cooked and eaten, fruits are washed and removed. Skin, etc., can reduce the harm.
Due to the different types of pesticides, simply immersing in fresh water or cleaning with food alkali or detergent is not the best method. Try to buy green and organically grown fruits and vegetables, especially green leafy vegetables. "Every day we eat 5 'clean fruits and vegetables' on the list, and the body's absorption of pesticides can be reduced by 92%," said EWG chairman Ken Cook.
Peeling to eat also cannot avoid pesticides
Today, pesticides are pervasive. In the soil of farmland, herbicides and fungicides are always sprinkled, and they all enter the fruit trees from the roots. In order to reduce pests such as borers, pesticides are also poured from the bark and flow through the tree along the conduits and screens in the trunk. In other words, pesticides cannot be avoided even if peeled. Because most pesticides are not exposed from the skin at all, most orchards today are bagged after fruit set, reducing the chance of direct contact with any pesticide.
High content of heavy metals in the peel
A study found that the lead content in apples that are close to the road edge increased significantly, while the lead in the skin was significantly higher than that in the flesh. Another study found that the concentrations of heavy metals such as lead, cadmium, copper, tin and antimony in the peel were significantly higher than those in the pulp. However, the study also found that because the lead in the exhaust gas is absorbed directly in contact with the skin, the amount of lead in the skin can be reduced by as much as 80% if it is put on a bag.
Is there any nutrient in the peel that is worth our risk?
Zinc, which is beneficial to the human body, is easily lacking in the diet, and chromium, which is beneficial to the prevention of diabetes, has a peel concentration that is four times that of pulp. At the same time, the content of polyphenols in the skin is much higher than that of the flesh.
A study determined that the total polyphenol content in apple peel reached 307 mg/100 g, total flavonoids were 184 mg/100 g, and proanthocyanidins were 105 mg/100 g. These figures are beyond the reach of pulp. The study found that the polyphenols extracted from apple have a significant anti-radiation effect, which can delay the survival of irradiated animals; it also has the effect of promoting the elimination of lead pollution in animals, significantly reducing the liver and bone of lead poisoning mice. And blood lead content.
It can be seen that although apple skin contains slightly more lead than pulp, it also has a powerful ability to help eliminate lead poisoning. Comparing the two, the balance between benefits and harm is not so terrible.
After all, the benefits of eating apples are largely due to its nutrients and health-care ingredients. Without these things, drinking pure water every day, what's the point?
Advice on eating peel 1:
It may be preferable to choose a bagged apple. The apple skin is clean and uniform, and it is less affected by polluted gas and pesticide spraying.
Advice on eating peel 2:
Apple matures in autumn, fresh apples sold at the time without preservatives, eating the skin is more secure. The most worrying is foreign apples that have crossed the oceans because they must be kept fresh and waxing of foreign fruits is more common.
Advice on eating peels 3:
There is a natural layer of fruit wax on the surface of fresh apples, but there is also a thin fruit powder, which is not a light look. After the apple is harvested, in order to increase the value of the product and delay the dehydration of the apple, a waxing machine is often used for polishing, and there may be problems such as preservative treatment, so that the apple with a particularly bright surface is seen, especially an off-season apple. It's best to peel it before eating.
Eating Peel Advice 4:
The best choice is to have a non-pollution, green, and organic certified apple. Such an apple will have much less heavy metal and pesticide residues. Even if it is not equal to zero, it will have less residue than the ordinary apple skin and eat the peel more at ease.
