Grapes are one of the most popular fruits worldwide. They are not only delicious but also packed with numerous health benefits. Grapes come in different colors and varieties, each with its unique nutritional effects.

For instance, green grapes are known to have a good effect on clearing away heat and detoxifying, while black grapes are known to promote strong bones and muscles. Additionally, grape skins and seeds are richer in nutrients, making them an excellent source of antioxidants, vitamins, and minerals.

However, when choosing grapes, it's crucial to be vigilant, as some grapes may be contaminated with pathogenic bacteria or scale insects, which can be harmful to our health.

Two types of grapes that need particular attention are those with small protrusions on their surface and those with black spots. These grapes are usually infested with bacteria or insects and should be avoided.

To ensure that we pick the best grapes, here are some classic methods to follow:

First, look at the skin. Grapes with darker colors and hoarfrost on the surface are usually good grapes. This is because the natural color of ripe grapes is darker than that of unripe grapes. Additionally, the hoarfrost on the surface of grapes is a sign that they have not been treated with pesticides, making them safe and healthy to eat.

Second, check the grapes' plumpness and smoothness. Good grapes should feel tight and have a smooth structure. Each grape grain should be next to the other, indicating that they are fully ripe and healthy.

Third, taste the bottom one of the whole bunch of grapes. This is because the grape at the bottom of the bunch receives the least photosynthesis and lacks the most nutrients. If it's very sweet, it usually means that the whole bunch of grapes is very sweet.

Fourth, check the grape stem to see if it is newly picked. The grape stems should feel green and fresh, indicating that they have just been picked. Additionally, the grapes should feel firm when pinched.

Grapes are a delicious and healthy fruit that is packed with numerous health benefits. When choosing grapes, it's crucial to follow the above methods to ensure that we pick the best grapes that are safe and healthy to eat. By doing so, we can enjoy the full nutritional benefits of this fantastic fruit.
