Is puffed food harmful to health? Puffed food is our favorite snack in entertainment and leisure, such as potato chips and chips. Then there will be a question, whether it has an impact on our health. Let's see if puffed food is harmful to health.
Is puffed food harmful to health? 1 Puffed food is a kind of junk food. Its biggest harm is lead poisoning, which is difficult to be discharged after accumulating in the human body. When the lead content in blood is high, it will affect the nervous system, cardiovascular system, digestive system and hematopoietic system, causing mental retardation, anorexia, anemia and vomiting.
Therefore, it is better to eat less puffed food!
Puffed food, also known as extruded food, explosive food and light food abroad, is a new type of food developed internationally in recent years. It uses grains, beans, potatoes and vegetables as raw materials, and is processed by expansion equipment to produce a variety of foods with beautiful appearance, rich nutrition, crispy and delicious.
Therefore, a large category of food has been formed in a unique way. Due to the simple structure, convenient operation, less equipment investment and quick income, the equipment for producing this puffed food has developed rapidly, showing strong vitality.
Due to different uses and equipment, puffed food has the following three types:
One is to use corn and potatoes as raw materials to produce snacks through an extruder;
Secondly, using plant protein as raw material, tissue protein food (plant meat) is produced by extrusion extruder;
The third is to use cereals, beans or potatoes as raw materials and make them into staple food after puffing. In addition to the trial production of indirect heating puffing machine, a variety of puffed foods were made from refined grain puffed powder.
1. Staple food: sesame seed cake, bread, steamed bread, pancakes, etc.
2. Camellia oleifera: puffed noodle tea.
3. Military food: compressed biscuits.
Snacks puffed food
Category: popcorn, popcorn, etc.
5. Cold food: the stuffing of sorbet and popsicle.
Some of the above foods, such as puffed flour tea, printed cakes and compressed biscuits, are all made of puffed coarse grains. Some varieties are only mixed with a certain proportion of puffed coarse grains.
Although expansion technology belongs to physical processing technology, it has its own characteristics. Expansion can not only change the shape and state of raw materials, but also change the molecular structure and properties of raw materials and form some new substances.
Is puffed food harmful to health? What are the hazards of puffed food?
1, which is not conducive to nutritional balance.
Excessive additives in puffed food lead it to be called compound food with high fat, high calorie, high salt and high carbon. Long-term and large-scale use will easily lead to unbalanced nutrition intake, and high-fat and high-calorie food intake is extremely unfavorable to cardiovascular and cerebrovascular health. Long-term consumption will increase the risk of hypertension and cardiovascular disease.
2, affect appetite
Because puffed food contains high calories, it is easy to make people feel full after eating puffed food, which has an adverse effect on eating. If you eat it regularly, it will affect the normal nutrient intake, which will easily lead to insufficient intake of various nutrients in the human body and eventually lead to malnutrition.
3, easy to lead to obesity
Generally, puffed food has a high fat content, and excessive intake of puffed food will lead to a large accumulation of fat in the body, which is easy to cause obesity.
4, may lead to lead poisoning.
In the process of adding functions, puffed food may come into contact with metal containers containing lead and be contaminated. If the puffed food contaminated with lead is used for a long time, it will lead to the accumulation of lead in the body, which will have a negative impact on children's growth and intellectual development.
5. Oil deterioration is harmful to health.
According to different puffing processes, some puffed foods need to use oil in the processing, which is called oily puffed food. Because oil is easy to be oxidized, deteriorated and rancid during storage and heating, peroxides, aldehydes, ketones and so on. This may be harmful to health, which will not only reduce the nutritional value of food, but also cause harm to health. The recently reported carbonyl valence is an identification index of fatty acid corruption. The higher the carbonyl value, the higher the degree of fat oxidation, the more harmful substances that may generate heat, and the worse the quality of oil products.
6. How to choose puffed food?
1 Select products with complete and detailed identification description. In particular, the production date and shelf life of products should be standardized and clearly marked, and the "QS" production license mark should be recognized when purchasing.
Choose products with full bags and no air leakage. Bagged puffed food is often filled with gas, which makes the product difficult to absorb moisture and has high freshness. At the same time, the internal products are protected from being squeezed and crushed during storage, transportation and sales. Open the package and smell the smell of the product. There should be no pungent smell, no mildew in appearance and crisp taste.
Check the ingredient list and see the "nutrition label" on the ingredient list. The nutrition label is usually labeled "1+4", which refers to the content of energy plus four core nutrients (protein, fat, carbohydrate and sodium). Consumers should use the nutrition label to look at the upper limit of daily intake, calculate how much nutrition they need every day, and then decide how much to eat and how much to buy puffed food.
Is puffed food harmful to health? Eating too much puffed food will have a great influence on children's intellectual development. How much do mothers know?
Puffed food is a crisp, sweet and varied snack food. Its main raw materials are all kinds of cereals (such as rice, corn, beans and potatoes), with various seasonings and leavening agents, which are processed by special equipment.
In recent years, puffed snacks are deeply loved by children because of their crisp, crisp, fragrant and sweet taste characteristics. However, medical experts at home and abroad believe that puffed food is not really safe or healthy food. If children eat this food for a long time, it is harmful to their brain and physical development.
American nutrition food experts suggested many years ago that puffed food contains many harmful metal elements such as lead or aluminum, so parents should not let their children eat these foods often.
The reasons for the high content of lead and aluminum in puffed food are as follows:
First, additives such as fillers are often added in this kind of food processing, and some fillers (such as alum and sodium bicarbonate) contain more heavy metals such as lead or aluminum;
Second, food passes through metal pipes during processing. Metal tubes usually contain alloys of lead and tin. At high temperature, lead is easy to volatilize, and the volatilized lead will pollute these puffed foods.
Eating puffed food often is very harmful to children (especially children under 3 years old). After a long time, lead will slowly lurk in the blood and bones, and it is difficult to metabolize it naturally.
Children are in the stage of growth and development, and their absorption of lead is several times that of adults, while children's excretion of lead is weak and it is easier to accumulate in the body.
When harmful heavy metals accumulate to a certain amount, it will cause obvious damage to the nervous, digestive and hematopoietic systems of human body, especially cognitive impairment or decreased thinking ability, and may even affect children's lifelong health.
