There is no clear concept of junk food in nutrition, but the common sense of “junk food” generally refers to high oil, high added sugar, high salt and trans fatty acids and other excessive content of food. Its main hazards are that it may lead to excessive fat intake, excessive added sugar intake, and excessive sodium intake.
1. Excessive fat intake: Dietary guidelines recommend 25-30 grams of cooking oil intake for healthy adults per day. Junk food is usually high in fat, and prolonged overconsumption of junk food can easily lead to excessive fat intake, which can lead to obesity, hyperlipidemia, hypercholesterolemia and other health problems.
2. Excessive intake of added sugar: Dietary guidelines recommend that healthy adults have less than 50 grams of added sugar per day, and it is best to keep it below 25 grams. Long-term intake of junk food, such as all kinds of cakes, etc., leads to excessive intake of added sugar, leading to obesity, dental caries and other health problems, and aggravate blood sugar fluctuations in diabetic patients.
3. Sodium salt intake exceeds the standard: healthy adults daily sodium salt intake in the following 5 grams. Part of the junk food sodium content is very high, such as various types of preserved foods, processed dried fruit and so on. Excessive sodium intake can increase the incidence of hypertension in the long run.
It is recommended to minimize the intake of junk food and consume more natural and healthy ingredients to maintain good health.
