1. Reducing the amount of salt used should be the first principle for consumers to add salt. On the basis of reducing salt, consider whether to choose low-sodium salt. Normal people who have salty taste preferences and cannot control the amount should choose low-sodium salt.

2. Don’t look at the price blindly. Not all high-priced salts are better than low-priced salts. The test results of some high-priced salts such as moisture, particle size, whiteness, water-insoluble matter, purity (sodium chloride content), total mercury, nitrite and other indicators are not as good as those of low-priced salts, so don’t blindly think that higher prices are better. .

3. It is not practical to supplement mineral elements through table salt. Don't believe in advertising slogans such as "the healthiest salt", "richer and more comprehensive in mineral nutrients", etc. There is no need to specifically choose micronutrient-fortified salts to supplement mineral elements. If you are not picky about your daily diet, you will generally not lack trace elements.

4. Choose salt according to your actual needs. For example, patients with thyroid disease should choose non-iodized salt or iodized salt under the guidance of a doctor, and residents living in high-iodine areas should choose non-iodized salt (citizens can go to the Chongqing Salt Industry Information Network to check the sales address of non-iodized salt); The elderly, pregnant women and patients with high blood pressure should consume more low-sodium salt.

5. When purchasing, choose small-package brand salt sold through regular channels to ensure safety. The second is to choose products with fewer additives. For iodized salt, consider giving priority to salt with seaweed iodine.

6. When purchasing table salt, you should pay attention to the production date. When purchasing, be sure to pay attention to the production date and shelf life of the product. The closer the production date, the more guaranteed the product quality.

7. Pay attention to check the packaging when purchasing. It is best not to buy those with loose seals or cracks. You can also pinch the bag when purchasing. If there are obvious lumps in the bag, do not buy it.
