Many people have the mind of puffed food is junk food, but this is not correct. Maybe some snacks is not heathy, but we can not say that all snack foods are unheathy.

First of all, let's first understand the definition of junk food, high fat, high calorie, and high salt. The raw materials of puffed food are mainly beans, cereals, and potatoes. The main ingredients are carbohydrates and protein, and contain high dietary fiber. Therefore, it is incorrect to blindly label them as "junk food".

Puffed food is conducive to the utilization of coarse grains. Coarse grains have been rejected by many people because of their poor taste. However, the nutritional value of coarse grains is very high. Especially when people eat too much refined white rice and noodles, the appropriate intake of coarse grains not only plays the role of providing timely help, but also making things better, it increases people's intake of dietary fiber, increases the intake of trace elements and a variety of minerals, and plays an extremely important role in strengthening physical fitness and preventing diseases. The structure of coarse grains changes during the puffing process and becomes loose and swollen. The Maillard reaction generated during the puffing process increases the color and flavor of the food, which is a model of fine preparation of coarse grains.

To some extent, some snacks can provide coarse food grains in tasty flavor, so we have them with pleasure and that help us intake more whole grain.
