What is Junk Food:

The top 10 junk foods published by the World Health Organization include:

Fried foods, pickled foods, processed meat products (jerky, meat floss, sausages, ham, etc.), biscuit foods (excluding low-temperature baking and graham crackers), soft drinks and cola beverages, convenience foods (mainly referring to instant noodles and puffed foods), canned foods (including fish, meat and fruits), canned plum and preserved fruits, frozen desserts (ice cream, popsicles, ice cream, etc.), barbecue foods.

Junk food has the following three meanings:

1) Poor nutritional quality.

Meaning, we happily fill it in our stomachs, but it doesn't work as nutritious as it should, for example, we want calcium without calcium, we want potassium without potassium, and there are pitiful few vitamins. However, they occupy our stomachs, and other useful foods are inevitably eaten less, which eventually leads to nutritional deficiencies and hinders people's health.

2) It is easy to make people gain weight unconsciously.

This means that although the nutrient content of these foods is relatively low, the ingredients that promote human obesity are high. For example, it is high in fat, high in sugar, a lot of starch, and it is not easy to feel full when you eat it. What about the results of eating more? Of course, people are prone to obesity.

3) It is not conducive to the prevention of chronic diseases.

Always eating a lot of sugar and refined starch, blood sugar rises very quickly, which is easy to promote human aging, and is not conducive to the prevention of diabetes. Always eat foods with a lot of fat, especially fried foods and crispy foods, which are prone to dyslipidemia. Besides, oil, sugar, and refined starch all promote obesity, and as soon as a person is fat, various chronic diseases will naturally follow.

Junk food usually refers to foods that are burnt, high in oil, salt, and sugar. These foods are very easy to make people fat, if you eat more of these foods, it is easy to make people undernourished, and can regret that it can have a significant impact on physical health.

It is unscientific to classify all "triple high" foods as "junk food" because fat, calories and sugar are essential energy for the human body**. Professor Yang believes that fried and barbecued foods contain a large number of carcinogens, and some pickled, puffed foods and refined meat sausage foods contain a large amount of nitrite, which has caused huge potential harm to the human body, and can be called "junk food" to the letter. There are also some high-fat, high-calorie foods, such as cream cakes and some fresh desserts, although they belong to the "three high" foods, but do not contain other chemical components harmful to the human body, only when people's dietary structure is unreasonable, partial to eat these high-fat, high-sugar food, resulting in excessive caloric intake and lack of other nutrients, these foods become "junk food".

If you have a balanced diet, use these foods in moderation, and consume sufficient amounts of protein, vitamins, minerals and other nutrients, so that fat occupies a scientific and appropriate share in the dietary structure, at this time, it cannot simply be said that all high-calorie, high-fat, high-sugar foods are "junk food crystals".
