Although nuts contain a lot of vitamins, protein, trace elements and other nutrients, they also contain a lot of fat.
As the saying goes, "one or two peanuts and one or two oils, one or two melon seeds and two oils"; In addition, some nuts also contain carbohydrates such as starch and sugar.
Eating too much can easily lead to an increase in blood sugar.

Nut storage crisis in frying stalls
When many people buy these nuts, they like to go to the frying stall to buy them. They think they are fresh and taste better. As everyone knows, there may be many health traps hidden behind these nuts!
1 taste
It's not hard to find that the nut flavors on the market are endless. Baked salt, charcoal, cream, etc., and some even have color!
Nuts with different tastes mean that other ingredients and additives have been added.
Although they are all within the standard range, eating too much will be harmful to the human body, especially for some patients with diseases.
Therefore, it is recommended to choose the original flavor as well.
Two fried nuts
Nuts contain a lot of fat, protein, carbohydrates and other foods, which will not be destroyed by ordinary heating.
But if the nuts are burnt, these nutrients that were originally beneficial to our health will be transformed into carcinogens such as benzopyrene. So try not to eat fried nuts.
