Tests show that puffed food, although the taste is delicious, but from the composition structure, belongs to the high-fat, high-calorie, low-crude fiber food. From the dietary structure analysis has its certain defects, can only occasionally eat. Long-term consumption of large quantities of puffed food will cause high fat, calorie intake, insufficient crude fiber intake. If the movement is insufficient, it will cause the accumulation of body fat and obesity. Children eat a lot of puffed food, will affect the normal diet, resulting in a variety of nutrients can not be guaranteed and supply, easy to malnutrition. Puffed food in general high salt, high MSG, so that the child is easy to lead to hypertension and cardiovascular disease in adulthood. Puffed food substandard products the main problem is bacterial contamination, such as coliform exceeded the standard, these will lead to children gastrointestinal discomfort, diarrhea and liver damage.

In order to prevent puffed food is squeezed, broken, to prevent oxidation of product fats and oils, rancidity, a lot of puffed food bags to be filled with gas, the data show that puffed food packaging should be filled with nitrogen, it is clean, non-toxic, dry, can ensure that puffed food for a long time does not discolouration, tasteless, safe to eat. But many of our manufacturers use compressed air, compressed air moisture content than normal air, will

Cause the bag puffed food taste is not crisp, and in the process of compressed air, there is a possibility that the machine injected into the lubricating oil as a mist, sprayed into the bag, attached to the inner wall of the bag, stained on the puffed food. So in the purchase of puffed food, if you find the bag labeled with the word filled with nitrogen, you can rest assured. If you find that the packaging leakage, it is not advisable to buy

The food itself, its nutrition is not comprehensive, it has four high characteristics: high sugar, high fat, high calorie, and then there is a very high content of monosodium glutamate (MSG), the child ate too much will undermine the nutritional balance. And puffed food is easy to cause a sense of fullness, affecting normal meals, will prevent the body from absorbing nutrients. At the same time, experts pointed out that in the production process of puffed food will have lead into the food. Puffed food is usually high in lead content, mainly from several sources: some food additives such as bulking agents; food in the process of processing is through the metal pipes, metal pipes usually lead and tin alloys, in the case of high temperature, the lead will be vaporized, vaporized after the lead will contaminate the puffed food. Children are in the stage of growth and development, the absorption of lead is five times that of adults, but the excretion of lead is weak, so lead is particularly easy to accumulate in children's bodies, resulting in long-term, chronic harm, and may even affect lifelong health. The harm caused by lead is very obvious, the main manifestation is some neurological behavior. The main manifestation is some neurological behaviors, such as low attention span, poor memory, hyperactivity, impulsivity, temper tantrums, and so on. But if the dose is relatively large, the degree of poisoning is relatively deep, it will seriously jeopardize the development of the child's intelligence and the health of the nervous system.
