There is always a group of shipments around us. For the food, the happiest thing is to eat! However, the foodies, do you understand the "instructions" on the food packaging ? What is the significance of the "Year Manual" on the packaged foods?
1. How to read the ingredients list on the food packaging bag?
Expert Answer: The ingredient list on the food packaging bag is used to mark the main ingredients, auxiliary materials and various additive ingredients used in the production of this food, that is, to mark all the ingredients that make up this food. According to the relevant provisions of the Food Safety Law, the ingredient list on the food packaging bag is generally arranged in descending order of the proportion of the added amount, and the most content component is ranked first. This type of push. By reading the ingredient list, we can know whether this food is so-called “real priceâ€. For example, many consumers will mistakenly think that “sour sour milk drink†is also milk. In fact, comparing the ingredient list of “sour sour milk drink†with the “pure milk†ingredient list, it will be found in the “sour sour milk drink†ingredient list. In the first place is water, and the “pure milk†ingredient list is ranked first in raw milk. Therefore, the sour milk drink is not milk, so everyone remembers.
2. What should the nutrition list on the food packaging bag look like?
Experts answer: The common nutrient composition table is generally composed of nutrient items, content values ​​and percentage of nutrient reference value (NRV%). The Nutrient Project lists the names of the nutrients contained in the product, where energy, the three major nutrients (protein, fat, carbohydrates) and sodium are clearly marked parts, which is often referred to as “1+4†( “1†refers to energy, “4†refers to three major nutrients and sodium). Other nutrients can be freely labeled. For example, dairy products are often labeled with “calciumâ€, and high-fiber products are also labeled with “dietary fiberâ€.
Each serving refers to the amount of nutrients in the “this†base. Different products have different definitions for each part. The most common one is to calculate the content per 100g or 100ml, and some products are in one package. Please pay attention to distinguish when viewing. Nutrient Reference Value (NRV) is based on the recommended dietary intake (RNI) and appropriate intake (AI) of Chinese residents (each nutrient has its own RNI or AI) for comparing nutrient content in foods. How many reference standards are a nutritional reference scale when consumers choose food. In other words, it refers to the amount of each nutrient in each product, which is the recommended reference value (every day).
3. The higher the nutrient content in the food nutrition label, the better?
Experts answer: It depends on what kind of people, if it is for people with high blood pressure, then the lower the sodium content in the food nutrient table, the better, this kind of food can be purchased; if it is the people who are losing weight The lower the value of energy, protein, fat and carbohydrate in the table of nutrients in the food, the better. If it is the person who is going to build muscle in the fitness, then the food with high protein content will be more preferential. help.
Therefore, the evaluation of the level of nutrients can not be generalized, and it is partial and comprehensive, and it is necessary to analyze the specific population.
