一个简单的Google：should we add salt to our food? 所有的医学专家的共识是：钠离子是人体必不可少的元素，但食品里自然含有足够的钠离子，无须额外加。对盐的限量，只有上限，没有下限。比如这里：
Once your child is eating the same foods as the rest of the family it is important to continue not adding any salt to their food. This will also benefit the rest of the family! It is at this point that children’s salt intake tends to increase dramatically due to eating higher salt foods.
Homemade meals cooked using fresh ingredients are naturally lower in salt than convenience meals and processed food. Limit foods that are high in salt, and always check nutritional information, even on products aimed at children, and choose those with less salt. A low salt diet throughout childhood will help prevent children developing a taste for salty foods and reduce the likelihood of them eating a diet high in salt during adulthood.
