Grapes are rich in nutrients such as anthocyanins and polyphenols. Among them, resveratrol, a polyphenol, can help boost the body’s antioxidant defenses. When buying grapes, have you ever noticed the white, foggy layer on the skin?

Some people mistakenly believe it’s pesticide and wash their grapes carefully before eating. What exactly is this powder? Is it harmful to your health?

Eat grapes without spitting out the skins or seeds.

Grapes are rich in nutrients, including carbohydrates, protein, fat, and vitamins A, B1, B2, B12, C, and E. A moderate intake of grapes can help cells fight inflammation and prevent aging.

Grape skins contain not only anthocyanins and polyphenols, but also resveratrol, a polyphenol that has antioxidant and lipid-lowering properties, preventing arteriosclerosis and cardiovascular disease.

As for whether you should spit out the grape seeds, do you?

Grape seeds also contain proanthocyanidins, polyphenols, and other nutrients that help fight oxidation and reduce free radical damage. If your teeth are fine, eating grapes with the skin and seeds provides a more complete nutritional boost. To cater to consumer preferences, seedless grapes are now available in various varieties. Seedless grapes aren’t completely seedless; rather, they have smaller and fewer seeds, still packing nutrients and making them a great choice.

The white powder on the grape skins is “natural fruit powder”—it’s pesticide-free and non-toxic!

When buying grapes, you’ll often see a hazy layer of white powder on the skins. What is this powder? Many people mistakenly think it’s pesticide residue or dust. In fact, it’s grape powder, a natural product of the grapes. Fresher grapes tend to have a thicker, more evenly distributed white powder on them. It’s not pesticide residue and is not toxic.

There’s no need to wipe or scrape off the fruit powder when washing. The fruit powder helps retain moisture in the grapes, slowing spoilage. Washed grapes tend to spoil more quickly, so simply rinse them under running water before eating.

How to properly wash grapes?

The color of the stem can determine the ripeness of grapes. For more ripe grapes, wait until the stem turns from green to brown before eating.

It is recommended to use scissors to cut each grape, leaving a small section of the stem. This prevents direct removal by hand, which can cause impurities to seep into the exposed flesh.

Place the cut grapes in a basin of water, gently scrub them, and soak them for 30 minutes, changing the water 2-3 times.

How to store grapes

Remember, keep grapes out of water before eating, as this will cause them to spoil. After purchase, wrap them in newspaper to prevent dehydration and store them in the refrigerator. They typically keep for 1-2 weeks.

While grapes are nutritious and delicious, they are high in the glycemic index, so avoid consuming too many at once. The recommended serving size is 10-13 grapes (approximately 130 grams).
