Is apple peel more nutritious than apple flesh?

Many sources say that the most nutritious part of the apple is the part close to the skin of the apple, and eating it with the skin is the most nutritious, but the apples sold in the general market have paraffin wax in addition to pesticides.

Unbelief? You take a knife and gently scrape the surface of the apple, and you can quickly scrape off the thin wax in the shape of shavings (which feels like a candle). I've experimented with both domestic and imported apples here, and there is no one that doesn't wax.

Because waxed apples have a beautiful luster and a long shelf life.

No matter how nutritious you are, I'm afraid you don't want to eat so much wax in your mouth, right? Of course, if you can buy unwaxed apples, you can soak them in salt water for half an hour and then rinse them, and then you can eat them with the skin on, which I heard will remove the residual pesticides.

The main components of apple peel are cellulose and pectin, which our stomach and intestines cannot digest and absorb, but eating fruit peel is conducive to the formation of feces and is good for people with constipation.

I like to eat the skin, but I have to soak it in water for a while before I eat it, (it will taste better when I absorb enough water) and then wash it with a vegetable and fruit detergent.

Yes, I eat apples and never peel them.

It is best to wash and eat with the skin on.

The big red apple is one of the fruits that people like to eat.

As we all know, apples are very rich in nutrients, such as: minerals, vitamins, calcium, malic acid, fiber, etc.

Researchers have used microwave digestion technology to determine the mineral elements in apples, and in the study, researchers have found that the mineral element content of apple skin is higher than that of apple flesh. And the content of trace elements zinc, iron and copper in apple peel is 3 of the corresponding content in apple flesh of the same quality14 and 6 times.

Based on the edible and peel mass of an apple is 5:1, the pulp of about 2 apples is equivalent to the trace element content of the peel of an apple.

Wow, if you look at it this way, isn't the apple peel quite powerful? But there's more to come.

Apple peel has stronger antioxidant properties than the pulp.

Fresh apples contain proanthocyanidins, catechins, phlorizin, phloretin, glycosides, caffeic acid and chlorogenic acid. However, in addition to the above-mentioned substances, apple peel also includes flavonoids, and apple peel contains more phenols than pulp, while polyphenols and flavonoids are the main antioxidants.

Apple peel also has the effect of anti-cancer cell proliferation!

The anti-cancer cell proliferation ability of apple pulp has been measured, and they have concluded that the anti-cancer cell proliferation ability of apple pulp is poor. However, the apple peel used can well inhibit the proliferation of lung cancer cells. This is because apple peel contains a large amount of quercetone glycosides, which are not present in the pulp.

Apple peels also have the potential to be used as a food additive.

By extracting bioactive substances from apple peel to develop functional foods, apple peel powder as a very valuable food additive, can be used to produce fortified foods, and a small amount of apple peel powder can increase the content of polyphenols and flavonoids in food.

Now that you know that apple peels have such extraordinary effects, do you still peel apples when you eat them?

Of course, considering the problem of pesticide residues and wax on the surface of apples, you can still choose not to eat them, or soak apples in water for a short time and disinfect the skin before eating. ）

The nutrition of apple peel and pulp is not the same.

Apple peel contains the most dietary fiber, and the peel of a medium-sized apple contains grams of dietary fiber. The dietary fiber in apple flesh after peeling is only grams. Apple peel contains the most vitamins, medium size apples contain milligrams of vitamin C and 98 IU of vitamin A in the skin, and the pulp of peeled apples contains only mg and 61 IU of these two vitamins.

Eating apples with the skin on them protects memory, and quercetin, an antioxidant rich in apple peels, helps protect memory by helping to prevent brain tissue damage associated with degenerative diseases such as Alzheimer's disease.

Apple peel has nutritional value, apple peel is rich in antioxidants and bioactive substances, eating apple peel is good for health.

Apple peel contains many bioactive substances, such as phenols, flavonoids, and octacosanol, which can inhibit angiotensin-converting enzyme that causes increased blood pressure, and help prevent chronic diseases, such as cardiovascular disease, coronary heart disease, and reduce their incidence.

The nutrient content at the junction between the peel and the pulp is the highest, and the cellulose content of the peel is also very high, but now there are too many pesticide residues, so it is recommended that you do not eat it, otherwise it will accumulate in the human body and it is easy to get sick. If you want to eat fruit peels, you can choose green foods, organic foods are better.

The vitamin of apple peel is also very high, eat more apples, eat apple peel can be beautiful, and use apple peel on the face, it will make **very smooth, and it is very good to go to spots, if you take it to eat, I think you had better not peel it, because that will not destroy its nutritional value.

It's too cumbersome, I can't understand it, just say which one is more nutritious.
