Salt and Sodium
Salt is present in all our body fluids though there is more in the blood and fluid outside the cells than inside. The function of salt is to maintain all body fluids at an optimum level. The body loses salt in the urine and sweat, which is why. Sodium is present in most everything we eat. Fruits, herbs and flour contain the lowest amount. Some of them, such as apples, are so low that we don't count their sodium content. Sodium is high in baking powder, baking soda, soy sauce, cheeses and other food and cooking additives.
The Difference Between Salt and SodiumSalt is not sodium, but it does have a lot of sodium in it. Table salt is made up of 40% sodium and 60% chloride. Commercially produced table salt has 2,350 mg sodium per teaspoon. Sea salt's sodium count is nearly as high with 2,132mg per teaspoon. Salt is not always necessary in cooking. It is most often used as a preservative. The average salt intake in the UK is between 9 and 12 g per day. Current recommendations are to reduce salt intake to 6 g per day or less.
Is Sodium Essential For Your Health?Although some sodium is essential for your health, inadequate sodium intake is rare. We need less than 500 milligrams a day to stay healthy. A more common problem is a dietary intake of excessive amounts of sodium. Excessive sodium intake can cause fluid to be retained in the body tissues which can lead to high blood pressure, and can aggravate congestive heart disorders, certain forms of kidney disease and premenstrual syndrome. The best way to reduce sodium levels is to avoid or limit salt when you are cooking or dining and avoid processed food products, which often contains excessive amounts of sodium.
