What will the nutrition label indicate?
It is divided into two parts: compulsory identification content and selective identification content. According to 20 1 3,65438+10,1General Rules for Nutrition Labeling in prepackaged foods (GB 28050-20 1 1), prepackaged foods should indicate the contents of four nutrients and energy ("4+ 1). Among them, "4" refers to core nutrients, namely protein, fat, carbohydrate and sodium, and "1" refers to energy. If nutrition claims and fortifications are involved, the corresponding nutritional components and (NRV) should also be indicated. If hydrogenated oil is used, the content of trans fatty acids needs to be marked. As for other nutrients, they are marked selectively.
How to understand the numbers on the nutrition label?
Nutrition label mainly includes three parts: nutrition composition list, nutrition claim and nutrition function claim.
Nutrient composition table: very important, there are often three columns of data: the first column of data shows the types of nutrients mainly contained in this food; The second column of data reflects the contents of various nutrients in each 100 g/100 ml food or each food. The data in the third column, the percentage of NRV, reflects the ratio of nutrients in this food 100g to the daily requirement of human body. For example, in protein, if the NRV is 65,438+04%, it means that eating 65,438+000 grams of this kind of food can meet 65,438+04% of protein's daily needs. Among the types of nutrients, the current standards must indicate that energy, protein, fat, carbohydrate, sodium, calcium and iron are voluntary labels for enterprises.
Nutrition claim: that is, the claim of high and low nutritional components. For example, why can "high calcium biscuits" claim "high calcium"? Because of its high calcium content, it can meet the daily demand of 35%. So, it made a claim of high calcium. Of course, different foods can make various claims according to the characteristics of nutritional components, such as high protein, low fat, no fat, low sodium, no sodium, low sugar or no sugar, and the corresponding claims have strict standards.
The function of nutrients claims: for example, high-calcium biscuits can use the function of "calcium" to claim that it helps bones and teeth to be stronger. In the nutrition labeling standard, every claim of nutritional function has strict standard terms, and not a word can be changed.
By reading the nutritional characteristics of food marked on the label, we can choose food reasonably according to our health needs. For example, patients with hypertension pay more attention to the sodium content in the label, and they can choose low-sodium and sodium-free foods; Diabetic patients pay more attention to the identification of sugar. If you want to lose weight, you can pay attention to the energy standard in the label and choose low-energy and non-energy foods. This is the role of nutrition labels.
