The iodine content of spinach and celery is high, which can reach 1.64 mg and 1.60 mg per kg. In addition, the iodine content of kelp is 0.0 mg/kg/kloc-0. Marine fish and laver are also good foods to supplement iodine in daily life.
Therefore, the only food with high iodine content in nature is seafood, so we should pay more attention to eating this kind of food. They are the best natural iodine supplement products.
Calculation of daily intake of iodized salt
Take the purchase of 500 grams of iodized salt as an example, write down the date of purchase of iodized salt, and then write down the date of eating 500 grams of iodized salt, and you can know how many days it has been eaten. Divide the number of days of eating salt by the amount of salt eaten, and then divide it by the number of people eating at home, and you can get an approximate per capita intake of iodized salt.
It is worth noting that when calculating the amount of salt, the amount of salt ingested through soy sauce should also be added, and the calculation method is the same as above. The salt content in soy sauce is about 18%. As long as the amount of soy sauce is multiplied by 18%, the per capita salt intake of soy sauce can be obtained. Add this amount to the amount of salt, which is the daily average salt amount of everyone in the family.
