Have you ever had such a doubt: Why, when looking at the nutrition facts table of cookies, do you find that the combined proportion of various nutrients is not 100%? For example, the standard percentage values of nutritional elements in a certain type of biscuit are as follows: energy 24%, protein 10%, fat 32%, sugar 23%, dietary fiber 13%, sodium 23%, calcium 18%... Could it be that it shouldn't be the sum of these percentages equivalent to 100%? Why did it exceed 100%? What does it mean?

The percentage at the end of the nutrition facts table cannot be added. It means the content of that trace element as a percentage of the daily requirement. For instance, for every 100 grams of coconut juice consumed, it contains 2% of the daily energy requirement, 1% of the daily protein requirement, 2% of the daily fat requirement, 2% of the daily sugar requirement, and 1% of the daily sodium requirement. The nutritional content of this drink is not very high, but drinking it can cause abdominal distension. Therefore, if you give it to children, do not do it before meals. Besides, it's a pack of fries. The energy accounts for 8% of the daily requirement, the protein accounts for 3%, the fat accounts for 17%, among which the saturated fatty acids account for 25%, and so on...
