Changsha Evening News Changsha December 17 (Correspondent Qin Lu, All-Media Reporter Xu Yunyuan) Ms. Chen found that her 8-year-old child had significantly less appetite than before. After asking, she learned that the child's grandmother recently came to take care of her grandson and bought a lot of snacks that her grandson liked. After checking the packaging bags, she found that many of them were "junk foods" with high sugar, high salt and high oil. Now, Ms. Chen is so worried. How can the elderly learn to tell whether food is healthy? Today, the "Scientific Life" column group invited Sun Yan, director of the Nutrition Department and deputy chief physician of the Changsha Central Hospital (Changsha Central Hospital Affiliated to Nanhua University) to give popular science answers.

Sun Yan said that it can help the elderly learn to check the "nutritional labels" on food packaging. The National "General Rules for Nutrition Labeling of Pre-packaged Foods GB28050-2011" stipulates that the nutritional labels on food packaging must be mandatory to mark the following nutrients: energy, protein , fat, carbohydrate , and sodium. In addition, there are information such as "ingredient list", "production date", and "shelf life" in the food label.

What is prepackaged food ? Sun Yan explained that pre-packaged food refers to food that is pre-regulated or made in packaging materials and containers. The outer packaging is printed with food nutrition labels, which are specially used to show consumers product nutrition information. The nutritional component list includes the name, content and percentage of nutrient reference value (NRV).

How to choose food based on the nutritional content list? Sun Yan introduced in detail that the first column of the nutritional ingredients table is the name of the nutritional ingredients, that is, the "1+4" mentioned above - energy, protein, fat, carbohydrates, and sodium; the second column is the content. Try to choose foods with high protein content and low fat, carbohydrates and sodium content among similar foods, which are more conducive to health. For example, yogurt, you can choose high protein , low fat, and low sugar. Many carbohydrates in the nutritional ingredients table refer to adding sugar, so when choosing dairy products for your children, try to choose low carbohydrates; the NRV% in the third column refers to the percentage of the nutrient content provided by unit foods to the reference value of nutrients required daily, that is, when choosing snacks, try to choose foods with low energy, fat, and sodium. For example, a dessert contains 31.6 grams of fat per 100 grams, accounting for 53% of the recommended reference value for intake of quantitative nutrients. That is to say, eating 200 grams of the food is enough for an adult's daily fat needs. If you intake other fats (including fat for three meals a day), the amount of demand will exceed the standard, and in the long run, it will easily cause obesity. Generally speaking, NRV%≤5% is low, 10%≤NRV%≤19% is high, and NRV%≥20% is very high. When choosing snacks, try to choose the highest nutrients that are beneficial to health (such as protein, vitamins , minerals, dietary fiber , etc.), and try to choose the lowest nutrients that are not conducive to health (such as energy, fat, carbohydrates, sodium).

"In addition, we should also pay attention to the ingredient list." Sun Yan said that the ingredient list has an order. Generally speaking, the higher the ingredient list, the more added the amount, the larger the proportion. When choosing food, choose the fewer ingredients, the better. The shorter the food's ingredients list, the better. The fewer ingredients you don't recognize, the better. Sun Yan emphasized: The more additives in food, the more complex they are, the greater the safety hazards and the lower the nutritional quality. So, don't buy foods with a list of ingredients that are too long.

"Finally, check the production date and shelf life, and try to choose foods close to the production date. Foods with short shelf life are relatively safer and have fewer additives." Sun Yan explained.
