What to pay attention to when eating grapes

Most people can eat grapes, but diabetics should eat in moderation . People with anemia, high blood pressure, edema, nervous exhaustion, and fatigue should eat more. Grapes should be eaten cold, and those with gastrointestinal problems should not overeat.

1. Grapes and milk

Grapes increase the acidity of the stomach and milk is difficult to digest and absorb, and in severe cases can lead to diarrhea.

2. grapes and iron and calcium supplements

Do not take iron or calcium supplements with grapes if you are taking iron or calcium supplements, as tannic acid is like a "magic stone" and both iron and calcium are absorbed into the tannic acid, causing the iron and calcium to harden into a stone. It is recommended to wait 30 minutes before eating.


3. Grapes and water

Drinking water immediately after eating grapes can easily cause diarrhea. Diarrhea occurs because grapes are rapidly oxidized and fermented with water and stomach acid, which promotes intestinal peristalsis.

4. grapes, sulfonamides, and digestive enzymes

Grapes contain acidic components such as tartaric acid, which can alter the pH of the stomach and affect drug absorption. Sulfonamides for the treatment of urinary tract infections are highly soluble in alkaline environments and readily crystallize in acidic environments.

Some digestive enzyme drugs are effective in alkaline environments, but are easily destroyed and lose their effectiveness in excessively acidic environments. The above medications are also best taken 30 minutes away from the grapes.

1. what is frost on grape skins?

Frosting is a sugar alcohol substance secreted by grapes, also known as fruit powder. It is harmless to the human body and safe to eat. These frosts are naturally synthesized by plants and are not easily washed away because they are insoluble in water.

These frost frosts have a protective effect on the grapes, reducing water evaporation and preventing rapid water loss and shrinkage after harvest. This layer of frost does not dissolve in water and prevents the formation of a moist environment on the grape skins, thereby reducing bacterial infections.

Grape frost also contains yeast. Therefore, it is not necessary to add yeast when making wine.


2Storage of grapes

(1) Wrap purchased grapes in paper and store temporarily in the refrigerator. Do not use plastic bags as they cause frost on the surface of the grapes and lead to spoilage.

(2) Do not rush. Removing stems immediately exposes the grapes to air, attracts insects, and accelerates oxidation.

3. cleaning grapes

It is not difficult to clean grape bunches. Place a spoonful of flour in water, roll the grapes back and forth in the water, rub gently, and sift with clean water to remove any dirt from the grape skins.

Selection of grapes

1. look for frost.

The more frost on the surface of the grapes, the fresher and better the grapes will be. If there is no frost on the surface of the grapes, do not buy or eat them.

2. look at the color of the grape skins.

Grapes on the vine come in a variety of colors due to different light angles and amounts of light. If these grape ears are exactly the same color, there is no change in the shade of color, which is definitely not normal. Such grapes are very likely to be attacked by hormones.,


3. look at the stem of the grapes.

Stem thickness: If the grapes are hormone-containing, the stems will be correspondingly thicker. In normal grapes, the stem is just a thin vine.

Freshness of the berry stem: For fresh grapes, the berry stem should be green and full; for older grapes, the berry stem should be dark green and dry.
