With the improvement of living standards, people's demand for food has gradually shifted from simply solving hunger to pursuing taste and nutrition. However, among the dazzling array of foods on the market, some foods are called "junk food" because of their high calorie, high sugar, high salt and other undesirable ingredients. Recently, the 2023 junk food list was announced, and it is surprising that yogurt, which has always been regarded as a healthy food, is in second place, and the drink at the top of the list is even more surprising, because it is still the first choice for daily drinking in the hearts of many people. This article will provide an in-depth analysis of these so-called "junk foods" to help you understand the nutritional value and health risks of food more scientifically.1. The scientific basis behind the junk food list.
1. Imbalance between caloric density and nutritional value.
The selection of junk food lists is not groundless, but based on scientific research on the nutritional content and calorie density of food. Calorie density refers to the amount of calories per gram contained in a food, while nutritional value involves a variety of nutrients such as proteins, vitamins, minerals, etc. Junk food tends to have high calorie density and relatively low nutritional value, and long-term intake can easily lead to excess energy and unbalanced nutrition.
2. The influence of additives and processing process.
In addition to the basic nutrients, preservatives, colorings, flavorings, etc. added during food processing are also important factors in judging junk food. These additives may not only affect the taste and color of food, but may also cause potential harm to human health. In addition, over-processing can also destroy the natural nutrients in foods, further reducing their nutritional value.
2. Why yogurt is on the list: the problem of sugar and additives.
1. The nutritional value and benefits of yogurt.
Yogurt is a dairy product that contains probiotics, which have significant benefits in regulating the intestinal flora, boosting immunity, and more. At the same time, nutrients such as protein and calcium in yogurt also help maintain good health. However, this doesn't mean that all yogurts are healthy choices.
2. The problem of high sugar content.
In order to cater to the taste needs of consumers, many yogurt products on the market have added a lot of sugar. These sugars not only increase the calorie density of yogurt, but can also have a negative impact on human health. Long-term intake of foods high in sugar may lead to an increased risk of chronic diseases such as obesity and diabetes.
3. Hidden dangers of additives.
In addition to sugar, thickeners such as pectin and gelatin, as well as flavoring agents such as flavors and pigments, are added to some yogurt products. While these additives can improve the taste and appearance of yogurt, they can also be potentially harmful to human health. Therefore, when choosing yogurt, consumers should carefully check the product ingredient list and try to choose products with fewer additives and low sugar.
3. The Secrets of the Top Drinks: The Health Risks of Sugary Drinks.
1. The popularity and harm of sugary drinks.
Sugar-sweetened beverages refer to beverages that contain a high concentration of sugar, such as carbonated drinks, fruit juice drinks, etc. These drinks are widely popular for their sweet taste and convenient packaging. However, long-term intake of sugar-sweetened beverages can lead to serious health problems. High sugar intake is closely related to many chronic diseases such as obesity, diabetes, cardiovascular disease, etc.
2. **Sugar in sugary drinks.
In addition to directly added sugars, sugar-sweetened beverages may also contain **sugar. These sugars are mainly used in fruit juices, fruit juice concentrates and other ingredients. While these ingredients occur naturally, they may lose some of their nutritional value during processing, while the sugar content is relatively high. As a result, even sugar-sweetened beverages labeled as "natural" and "additive-free" may contain higher levels of sugar.
3. Suggestions for the selection of healthy drinks.
In order to reduce the health risks caused by excessive sugar intake, consumers should avoid sugary drinks as much as possible when choosing beverages. You can choose low-sugar or sugar-free drinks such as plain water and sugar-free tea as alternatives. In addition, a moderate intake of fresh fruits can also provide the body with the vitamins and minerals it needs.
Fourth, the analysis of knowledge points.
1. Balance between caloric density and nutritional value.
When choosing food, consumers should pay attention to the balance between the caloric density and nutritional value of the food. Foods with high calorie density can lead to problems such as energy surplus and obesity; Foods with low nutritional value cannot meet the body's demand for nutrients. Therefore, choosing foods that are low in calorie density and rich in high-quality protein, vitamins, and minerals is a healthier choice.
2. Safety issues of food additives.
Food additives play an important role in food processing, but excessive or improper use can be harmful to human health. Consumers should carefully check the product ingredient list to understand the type and content of food additives when choosing food. At the same time, it is also wise to pay attention to the results of the safety assessment of food additives by authoritative institutions.
3. Health risks and alternative options for sugar-sweetened beverages.
Sugar-sweetened beverages pose serious health risks due to their high sugar content. Consumers should be aware of the dangers of sugar-sweetened beverages and minimize their intake. Choosing low-sugar or sugar-free beverages and eating fresh fruit in moderation are healthier beverage choices.

Through an in-depth analysis of the 2023 junk food list, we can discover the hidden scientific basis and principles of food nutrition. In order to maintain good health, consumers should be more cautious and rational when choosing food, paying attention to key factors such as calorie density, nutritional value and additives.
