1, adding zinc salt: it can promote the immune function and growth of the body, and is helpful for children, pregnant women, the elderly and vegetarians.
2. Adding calcium salt: it can prevent diseases caused by calcium deficiency, such as rickets in children and osteoporosis in middle-aged and elderly people. When eating calcium salt, you should eat more foods rich in phosphorus, such as eggs and beans, and get more sunshine to increase the absorption of calcium.
3. Adding selenium salt: it has the effects of antioxidation, delaying cell aging, and protecting cardiovascular and cardiac muscle, and is suitable for middle-aged and elderly people and patients with cardiovascular diseases.
4. Adding iron salt: it is suitable for the iron supplement needs of infants, women and middle-aged and elderly people. Iron is the most abundant essential trace element in human body, and it is also the most easily lacking element.
5, riboflavin salt: suitable for long-term vegetarians, because such people may lack vitamin B2 and need appropriate supplementation.
6, low sodium salt: can reduce the risk of hypertension and cardiovascular disease, suitable for middle-aged and elderly people and patients with hypertension and heart disease. However, low sodium salt and high potassium content are not suitable for people with kidney disease and renal insufficiency.
I suggest you eat mainly zinc salt, and occasionally calcium salt and iron salt.
