There are six taboos for eating grapes.

1. Don't eat grapes with milk.

Grapes contain vitamin C, and some ingredients in milk will react with vitamin C contained in grapes, causing harm to the stomach. Taking both at the same time can cause diarrhea and vomiting in severe cases.

Don't drink water immediately after eating grapes.

Drink water immediately after eating grapes, and you may have diarrhea in less than a quarter of an hour. This is because grapes themselves have a laxative effect. Drink water immediately after eating grapes. The stomach will dilute gastric acid before digesting and absorbing water. Grape, water and gastric acid are rapidly oxidized and fermented, which accelerates intestinal peristalsis and leads to diarrhea.

Don't eat grapes after eating seafood

Eating fruits such as grapes, hawthorn, pomegranate and persimmon while eating seafood can cause vomiting, abdominal distension, abdominal pain and diarrhea. Because these fruits contain tannic acid, protein in seafood will solidify and precipitate, forming indigestible substances.

4. Eating grapes should not be excessive.

Because of the high sugar content of grapes, diabetics should pay special attention to avoid grapes. Pregnant women should beware of diabetes during pregnancy, so pregnant women should eat grapes in moderation. After eating grapes, it is advisable to eat products every 4 hours to avoid tannic acid in grapes and calcium in aquatic products from forming substances that are difficult to absorb and affecting health.

5. Be sure to rinse your mouth after eating grapes.

Some grapes contain a variety of fermented sugars, which are very corrosive to teeth. If you don't rinse your mouth after eating, the grape residue in your mouth is likely to cause dental caries.

6. Grapes should be thoroughly cleaned.

If you like grapes, remember to wash them thoroughly. There may be dirt on the grape skin, so it is inevitable to touch the grape skin when eating, which is not good for your health. Tell everyone a good idea. Soak the grapes in salt water for 10 minute, and the dirt left on the surface will be cleaned up.

Apples are rich in vitamin C, vitamin E, polyphenols and flavonoids, all of which are natural antioxidants and are particularly effective in preventing cardiovascular and cerebrovascular diseases. The calcium content of apples is much richer than that of ordinary fruits, which can help to metabolize excess salt and help to lose weight. But few people know that apple core contains hydrocyanic acid. Australian researchers found that apple core contains a small amount of harmful substance-hydrocyanic acid. A large amount of hydrocyanic acid is deposited in the body, which can lead to dizziness, headache, accelerated respiratory rate and other symptoms. In severe cases, coma may occur.

But don't worry too much. Hydrocyanic acid in apples mainly exists in the stone, but not in the pulp. Need to be reminded: eating apples is used to gnawing at the core, although it will not be poisoned immediately, but eating like this for a long time is really bad for your health.
