With the development of social media, micro-blog and micro-message rumors, as the main carrier of information, have become more and more common, especially in the field of food security, and are becoming the "hard field" of rumors. Nutritional supplement rumors have long circulated in friendly circles, causing panic and causing many people to "avoid" supplements, but do they really mean anything to supplements?

First, let's find out what a nutritional supplement is. By definition, a food additive is added to a food containing chemical or natural substances. According to The Life Times, the use of dietary supplements usually has the following goals:

1. Maintain or enhance the nutritional value of your food, such as the high-calorie nutrients in iron sauce.

2. As an essential ingredient or ingredient in some special foods, such as the baby's potassium carbonate diet.

3. Improve the quality and stability of food, such as food antioxidants in edible oils.

4. Improve the sensory properties of foods to improve their taste in the mouth, such as emulsifiers in ice cream.

5. Convenient for the production, processing, packaging, transportation or storage of food such as preservatives in food and canned fruit.

In fact, for most processed foods, it is almost impossible to produce them without adding the right amount of food additives.The country has strict rules on the dosage, coverage and usage of various food additives based on a scientific and thorough toxicity assessment, so that even products produced by conventional manufacturers (even containing food additives) do not represent a risk to human health, according to The Sinyang Daily.

In addition, many people are very interested in the quality of food when they buy food, they believe that more reliable food is harmful to health.However, according to the Health Times, the warranty period on food packages is determined by companies based on a number of specific experiments, so the shelf life of different types of food can vary widely: usually, bread, vegetables and other foods have a short shelf life, but biscuits, drinking water and so on.In addition, even the same foods may differ from each other due to differences in processing methods. For example, some foods may have a shelf life of up to six months, but only a few days, but may not be harmful to human health.If they are manufactured by a certified manufacturer and inspected by the appropriate authorities.So when shopping for groceries, it's best to go to a larger supermarket to make sure you're buying fresh, regular food.
