First, several points for attention when eating grapes:

1, you can'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 the effect of relaxing bowels and moistening intestines. Drinking water immediately after eating grapes dilutes the gastric acid before the stomach digests and absorbs water. Grape, water and gastric acid are rapidly oxidized and fermented, which accelerates intestinal peristalsis and produces diarrhea.

Don't eat grapes with milk.

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

Don't eat grapes after eating seafood

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

Second, several precautions for eating tomatoes:

1, not suitable for eating with cucumbers.

Cucumber contains a vitamin C decomposing enzyme, which will destroy vitamin C in other vegetables. Tomatoes are rich in vitamin C. If they are eaten together, they will not achieve the effect of supplementing nutrition.

2, should not be eaten on an empty stomach.

Tomatoes contain a large number of soluble astringents and other ingredients, which react with gastric acid and condense into insoluble blocks, easily causing discomfort such as flatulence and pain.

3. It is not advisable to eat immature tomatoes.

Green tomatoes contain alkaloid glycosides (solanine), which will make your mouth bitter and even toxic after eating.
