Is it good to eat apples at night? What are the nutritional values ​​of apples?

Nutritional value of apples

As we all know, apples are rich in vitamin C, vitamin E, polyphenols and flavonoids, which are all natural antioxidants and are particularly effective in preventing cardiovascular and cerebrovascular diseases. Apples contain much more calcium than ordinary fruits, which can help metabolize excess salt and help lose weight.

However, few people know that apple cores contain hydrocyanic acid. Researchers have found that apple cores contain a small amount of a harmful substance - hydrocyanic acid. When hydrocyanic acid is deposited in the body in large quantities, it can cause symptoms such as dizziness, headaches, and increased respiratory rate, and in severe cases, coma may occur.

But there is no need to worry too much, because the hydrocyanic acid in apples is mainly found in the core, not in the flesh. What needs to be warned is that if you are used to chewing the core when eating apples, although it will not cause poisoning immediately, it is indeed harmful to your health if you eat like this for a long time.

How to choose apples

So what should I do if there is wax on the apple skin?

From a nutritional point of view, you should choose to eat apples with the skin, because compared with the flesh, the apple skin contains more antioxidants. In fact, the wax on the apple skin is mainly divided into the following three types:

The first is the natural fruit wax on the surface of the apple. This is a lipid component and a plant protective layer generated on the surface of the apple. It can effectively prevent external microorganisms, pesticides, etc. from invading the pulp and play a protective role. It does not need to be removed.

The second type is the edible wax added to some imported apples. This "artificial fruit wax" is actually a chitosan substance, which is mostly extracted from crabs, shells and other crustaceans. This substance itself is not harmful to the body. Its main function is to keep apples fresh and prevent them from rotting and spoiling during long-distance transportation and long-term storage. It is also very simple to remove this layer of wax. Just rinse it with hot water.

The third type is industrial wax, which contains mercury and lead that may penetrate into the flesh through the peel and cause harm to the human body. The identification method is: wipe the surface of the peel with your hands or napkins. If a layer of light red substance can be wiped off, it may be industrial wax.

Apples of different colors have different health benefits

The color of an apple can indicate its health benefits. For example:

Red apples: more beneficial to the heart, improve memory, and maintain the health of the urinary system;

Green apples: better for strong teeth and bones;

Yellow apple: It can strengthen the human immune system and is also good for preventing certain cancers.

Traditional Chinese medicine believes that apples of different colors have different health benefits.

Red apples are good for the heart: they have a stronger effect in lowering blood lipids and softening blood vessels, and can protect cardiovascular and cerebrovascular health. The elderly can eat more of them.

Green apple: It has the effect of nourishing the liver and detoxifying, and can fight depression, so it is more suitable for young people. In addition, green apples can promote the growth of teeth and bones and prevent gum bleeding.

Yellow apple: It is very effective in protecting eyesight. Office workers who often use computers can eat it appropriately.

Benefits of Apple

As early as in ancient Egypt, people not only regarded apples as food, but also as medicine. Canadian research shows that apple juice has a strong effect of killing infectious viruses in test tubes, and people who eat more apples are much less likely to catch a cold than those who do not eat or eat less apples.

Apples contain a lot of potassium, which can combine with excess sodium in the human body and excrete it out of the body. When the human body takes in too much sodium, eating apples is helpful to balance the electrolytes in the body. The phosphorus and iron contained in apples are easily absorbed by the intestinal wall, which can nourish the brain and blood, calm the mind and promote sleep. The aroma of apples is a good medicine for treating depression and oppression.

After many experiments, experts found that among all kinds of smells, the aroma of apples has the greatest psychological impact on people. It has a significant effect in eliminating psychological depression. Clinical use has proved that after letting patients with mental depression smell the aroma of apples, their mood has greatly improved, they feel relaxed and happy, and the depression has disappeared.

Experiments have also shown that insomniacs can fall asleep more quickly and peacefully by smelling the scent of apples before going to sleep. Wash and squeeze apple juice, take 100 ml each time, 3 times a day, for 15 days as a course of treatment, it can lower blood pressure for patients with hypertension. Therefore, some scientists and doctors call apples "all-round healthy fruits" or "general practitioners".

The correct way to eat apples

It is best to chew apples for fifteen minutes

Apples have high nutritional value and are rich in vitamins and acids.

According to experts, it is not advisable to eat apples too quickly. If you chew them for a long time, more saliva and gastric juice can be secreted, which is beneficial to promote the body's absorption and digestion of apple nutrients.

From a nutritional point of view, we do not advocate eating in a hurry. For people with poor gastrointestinal tract, they should pay special attention to the speed of eating apples. Eating too fast can easily lead to indigestion and cause physical discomfort.

Everyone may have had this experience: after eating an apple for a long time, the bitten surface will turn yellow, and the moisture content of the flesh will decrease, becoming "softer" and less crisp. Experts explain that this is actually the result of apple oxidation. Although the "appearance" is not very good and the taste is not particularly good, in fact, its nutritional elements are not lost, and generally speaking, it will not cause harm if eaten.

Is it good to eat apples at night?

It is not a good habit to have this habit. Apple is a good thing and a fruit for losing weight, but the time you eat fruit is not good. If you eat at night and don't brush your teeth, it is not only bad for your body, but also for your teeth.

"Fruits eaten in the morning are gold, fruits eaten at noon are silver, and fruits eaten at night become copper." The saying "gold, silver, and copper" means that fruits eaten in the morning have the highest nutritional value, while fruits eaten at night have the lowest nutritional value. The reason is that when people get up early, the glycogen supplying the brain is depleted, and eating fruits at this time can replenish sugar as soon as possible. In addition, when eating fruits in the morning, various vitamins and nutrients are easily absorbed.

Therefore, I suggest you not to eat fruit before going to bed at night. Don't think that eating fruit is a trivial matter. It will have an impact on your body over time. Some habits can be developed, and some habits can be changed. We must cultivate living habits that are truly beneficial to our health.
