Apples are seasonal fruits in winter and are also fruits that are beneficial to the human body. However, it should be reminded that not everyone is suitable for eating apples, and some details should be noted when eating apples. Today, let's take a look at the nutritional value and precautions for eating apples.
Nutritional Value of Apples
Rich in zinc. Apples are known as the "fruit of wisdom" and the "fruit of memory." People have long discovered that eating more apples can improve memory and enhance intelligence. Apples not only contain essential nutrients for the brain such as abundant sugar, vitamins, and minerals, but more importantly, they are rich in zinc. According to research, zinc is a component of many important enzymes in the human body, a key element for promoting growth and development, and an essential element for nucleic acids and proteins closely related to memory. Zinc is also closely related to the production of antibodies and improving human immunity.
The water content in fresh apples is 85%.
Apples contain natural chemical antioxidants such as polyphenols and flavonoids, as well as a large amount of crude fiber.
Contains more potassium, which can combine with excess sodium salts in the body and excrete them. When the human body ingests too much sodium salt, eating some apples helps to balance the electrolytes in the body.
Contains elements such as phosphorus and iron, which are easily absorbed by the intestinal wall, and have the effects of nourishing the brain, nourishing the blood, calming the nerves, and promoting sleep.
The aroma of apples is a good remedy for treating depression and a sense of suppression. Experts have found through many experiments that among many odors, the aroma of apples has the greatest psychological impact on people, and it has a significant effect of eliminating psychological suppression. Clinical use has proven that after patients with mental depression smell the aroma of apples, their mood improves greatly, they feel relaxed and happy, and the sense of suppression disappears.
Next, let's understand what should be noted when eating apples.
Precautions for Eating Apples
Don't eat the apple core. The apple core contains a small amount of harmful substance—hydrocyanic acid. A large accumulation of hydrocyanic acid in the body can lead to symptoms such as dizziness, headache, and rapid breathing rate. In severe cases, coma may occur. But there is no need to worry too much. The hydrocyanic acid in apples is mainly present in the core, not in the flesh. It should be reminded that: if you are used to biting into the core when eating apples, although it will not cause poisoning immediately, eating this way for a long time is indeed harmful to health.
Be careful with waxed apples. Many apples are overuse of growth promoters, color enhancers, and enlarging agents during the growth process, or excessive use of preservatives during storage, and even the use of colorants, waxing, and bleaching and staining during sale, in order to cater to the psychology of consumers who judge fruits by their appearance. These toxic fruits have become a serious public hazard that seriously threatens people's health. Dangers of toxic apples: enlarging agents to increase size, color enhancers to enhance color, and preservatives to preserve freshness. Excessive use of enlarging agents, color enhancers, and preservatives can damage the liver. Retail fruit vendors will also apply industrial paraffin to apples to keep them moist and make the fruit body fresh and attractive.
Apples should not be eaten with seafood. Apples contain tannic acid, which not only reduces the nutritional value of seafood protein but can also easily cause abdominal pain, nausea, vomiting, etc. Similarly, other fruits rich in tannic acid, such as strawberries, bayberries, persimmons, pomegranates, lemons, grapes, and sour grapefruits, should not be eaten with seafood.
You cannot eat apples right after dinner. Eating apples 1 hour after dinner can promote digestion. However, eating apples immediately after a meal is not conducive to digestion.
Patients with ulcerative colitis cannot eat them. Patients with ulcerative colitis should not eat raw apples, especially during acute attacks. Because the intestinal wall ulcers become thinner, and the texture of apples is relatively hard, coupled with the stimulation of 1.2% crude fiber and 0.5% organic acid, it is not conducive to the healing of the intestinal ulcer surface, and it can mechanically act on the intestinal wall, easily inducing complications such as intestinal perforation, intestinal dilation, and intestinal obstruction.
