In China, the "4+ 1" model is mainly used to label nutrients. "4" refers to core nutrients, namely protein, fat, carbohydrate and sodium, and "1" refers to energy. These five items are closely related to the nutrition-related problems and chronic diseases of China residents. In addition, food manufacturers can also choose whether to label other nutrients, such as vitamins, minerals, dietary fiber and other categories.

The first two columns of the nutrient composition table are easy to understand. It should be noted that the units marked in the second column are different, generally divided into per100g (ml) or per serving, and the former is more common.

The third column of the nutrient composition table is the nutrient reference value %(NRV%), which represents the percentage of nutrient composition in 1 00g or100ml or1serving of food. For consumers, NRV% is the most important item in the nutrition label. Just look at this percentage, and you will know how much energy and nutrition you can bring by eating 1 00g or100ml or1serving.

Extended data

In the daily diet, try to choose foods with high protein, low fat and low sodium. If you pay more attention, sometimes you will see that some products are marked with trans fat under the fat. Due to the adverse effects of trans fats on human health, according to the General Principles of Nutrition Labeling in prepackaged foods, if hydrogenated vegetable oil is used in food raw materials, the content of trans fatty acids must be marked in the nutrition composition table.

The fact that the column of "trans fatty acids" in many packaged foods is marked as 0 does not actually mean that there are no trans fatty acids, because if the trans fatty acid content in each 100g solid food or 100g liquid food does not exceed 0.3g, it can be marked as "0". At this time, you need to check the ingredient list.
