General foods can be eaten within 1-2 months after expiration, provided that the quality is guaranteed. But there is no guarantee that this is the case, but most of them can be eaten, but for safety reasons, it is not recommended, because a small number of foods will go bad and moldy after the shelf life.

Chocolate shopping skills:

1, check whether it is cocoa butter: it should be noted that most of the common chocolates on the market are cocoa butter substitutes, which are made by a series of processing techniques and should not be eaten too much.

2. Check the composition. You can choose different flavors of chocolate according to your preference.

3. Check the production date. Ensure that the product is within the warranty period.

4. Choose imported chocolate. Imported chocolate is relatively pure, with less sugar and more mellow.
