Consumption of salt iodized and not iodized are both better, which needs to be analyzed according to the individual's situation.

For normal people can eat some iodized salt, can achieve the effect of supplementing the body of iodine, but also to avoid the emergence of iodine deficiency caused by the thyroid gland insufficiency and big neck disease. But for people suffering from hyperthyroidism, you generally need to use non-iodized salt, otherwise it will lead to excessive production of thyroid hormones in the body, which will also have an impact on the disease.

Selection of edible salt:

1, look at the quality grade of edible salt, give preference to superior or first-class edible salt.

Eating salt and rice flour and grain oil, is also divided into grades, with reference to China's "National Standard for Edible Salt", *** divided into three grades, respectively, superior, first and second level, the second level of edible salt white cleanliness is low, the particles are not uniform, and there will even be the presence of dust, so try to choose the superior and first level of edible salt in the purchase.

2, look at the ingredients list, the less additives in the salt, the better.

Most of today's table salt is refined salt with fine particles, the reason is that there is an anti-coagulant substance added to the table salt called: potassium ferrocyanide, this salt additive inhibits the table salt from clumping. Although the salt additives are within the range of national standards, but when buying many people are still willing to choose less additives salt.
