In life, except for bulk food, other foods usually indicate the nutritional components of the food on the packaging. The nutrient composition table mainly tells consumers how many main nutrients and calories there are in a certain amount of this food. For example, a standard nutrient composition table will tell you the total calories, protein, fat, carbohydrate, added sugar, sodium and so on in this food 100g. ?

There is another column in the nutrient composition table of some foods called? NRV%？ Many people think that this indicator represents the proportion of this nutrient in food, but it is not. This percentage represents the ratio of this nutrient to the recommended daily intake (or requirement). For people who lose weight, the data in this column is meaningless, so don't worry.

So how should people who lose weight look at the nutrient composition table? People who lose weight need to pay more attention to the calorie and fat content of this food. When we lose weight, we are used to using kilocalories as the unit of calories. In the nutrient composition table, sometimes the calorie of food is written as energy, and the unit is kilojoule. We often don't know how many calories a food has, so we need to convert kilojoules into kilocalories.

How to convert kilojoules into kilocalories? 1 calories =4. 184 calories. Therefore, when kilojoules are converted into kilocalories, we can roughly divide by 4. For example, the energy of a certain food is 2000 kilojoules per100g, then its approximate heat is 500 kilocalories per100g, which is more than four times that of rice, because the heat of rice is about110kcal.

If you are losing weight, what are the calories of snacks that are not recommended? Generally speaking, if the calorie of a snack exceeds 80 kcal per100g, it is not recommended to eat it. Snacks are eaten very little unless the intake can be controlled accurately.

The nutritional components of snacks are basically marked with the fat content per 100g. For example, the fat content of most cakes is about 35g per 100g, and usually a small cake is about 100g, which means that more than one third of a cake is fat. Eating a small piece is equivalent to drinking a few spoonfuls of oil, so be sure to avoid these seemingly insignificant snacks.

We may think that cakes are not greasy, because fat, flour and sugar are mixed together when making cakes, and the taste is in line with most people's preferences.

A snack, if its fat content exceeds 3 grams per 100 grams, don't eat it when you lose weight. Therefore, when buying snacks, you must look at the nutrient composition table, and be cautious about snacks with high fat and high calorie.
