“An apple a day keeps the doctor away.” Many people like to eat apples, not only because of their crisp taste, but also because of their high nutritional value. In particular, a scientific team from Hirosaki University in Japan has confirmed through research that the polyphenols in apples can inhibit the proliferation of cancer cells and have anti-cancer effects.

But there are two sides to the matter. There is a saying that apple peels can cause cancer! The reason is that if the attached pesticide is ingested into the human body, it will harm the health of the person who eats it.

Let’s look at a little apple with a lot of knowledge!

Few apples, high nutritional value

First of all, apples are rich in nutrients. Mainly include sugar, organic acids, vitamins, dietary fiber, minerals and enzymes.

The soluble sugar content in apples accounts for 8% to 13% of this ratio, of which fructose has the highest proportion, reaching 43.7% to 55.7%. Sugar is the body's main source of energy. If the body lacks sugar, it will cause hypoglycemia.

If you insist on eating an apple every day, your body will slowly produce 4 "changes", don't mind

Secondly, the natural chemical antioxidants contained in apples, such as Polyphenols and flavonoids can quickly remove metabolic "junk" from the body and reduce neutral fat content in the blood.

Third, it promotes physical activity. Enzymes in apples refer to enzymes. Most fruits and vegetables contain some amount of enzymes, including apples. Enzymes are catalysts for various reactions in the human body and can promote various activities of the human body. A lack of enzymes can prevent certain body activities from being completed successfully.

Fourth, apples also have certain anti-cancer effects.

Apple’s anti-cancer research

Italian researchers once conducted a survey. They analyzed the diets of 629 cancer patients in detail and found that eating more than an apple a day was harmful to colorectal, esophageal and throat cancer, while eating less than an apple a day was harmful. Cancer, breast and ovarian cancer are preventable, with risk control levels ranging from 9% to 42%.

Cornell University researchers isolated various compounds from 24 pounds of apple peels and tested each component's effect on cancer cells grown in the laboratory. They found that there are more than a dozen triterpenoids in apple peels such as flavonoids and dietary fiber in the experimental environment, which can not only effectively inhibit the proliferation of cancer cells, but also directly kill cancer cells, especially for human liver cancer Hep G2 cells. MCF-7 human breast cancer cells and CaCo-2 human. These three effects of colon cancer cells are more significant.

Regarding the research on the anti-cancer effects of apples, some analysts believe that the anti-cancer effect of apples may come from the free flavonoids in apples. As a natural antioxidant that is easily absorbed by the body, it can reduce the body's genetic material, DNA. Oxidative damage, thereby reducing the possibility of cell mutation and achieving anti-cancer effects.

However, the above research also has certain limitations. For example, the number of subjects investigated is too small to be generalizable, and animal experiments do not mean they will have this effect on humans. Therefore, we need more evidence and clinical data on whether eating apples can actually help us fight cancer. How to eat apples healthily?

Some people like to peel apples when eating them because they have heard that pesticide residues or artificial wax on the apple skin can cause cancer, or they feel that the apple skin is not easy to digest.

Apple skins do have more pesticide residue and artificial wax than the pulp, but only eat one or two apples a day. The amounts of pesticide residues and artificial waxes ingested do not actually pose a threat to humans, and there is no evidence that these pesticide residues and artificial waxes are carcinogenic.

In fact, these substances are basically combined with dietary fiber and will not be absorbed when entering the human body. However, they will be directly eliminated from the body after entering the large intestine. Therefore, there is actually no need to worry about the health effects of the peel. threaten.

In addition, the dietary fiber, anthocyanins and antioxidants contained in the peel greatly exceed the content of the pulp, and have better gastrointestinal health and anti-cancer effects, so there is no need to worry about the digestibility of the apple peel.

Of course, if you're really not used to eating apple peels, it's okay to peel them off. If you lose interest in eating apples because of the hassle of peeling them, you'll get more than you're worth, so you don't have to worry too much.

Apples are good food, but if they are decayed and more than 1/3 has been eaten away, they are not suitable for consumption. If they become moldy, even if only one corner is moldy, they must be thrown away as the mold will spread throughout the apple tissue. Cut away the moldy parts, as well as other parts that are still invisible and still contain a lot of mold and toxins that are invisible to the naked eye. The ingestion of mold poses serious threats, such as food poisoning and cancer, that are much scarier than pesticide residues.

In addition, patients with ulcerative colitis should not eat raw apples. The hard texture of apples, coupled with the stimulation of 1.2% crude fiber and 0.5% organic acid, is not conducive to the healing of the intestinal wall ulcer surface and can be mechanically affected. The action of the intestinal wall can easily cause complications such as intestinal perforation, intestinal dilation and intestinal obstruction.

Introduction: Apple can be said to be a cheap and high-quality fruit in everyone's eyes. It is rich in nutrients and has many health benefits. However, we cannot consider it a "health product". We should focus on treating the disease and maintain a rational attitude.
