Salt has been use to flavor and preserve foods for thousands of years and even had a great effect on the economy of empires. Today, you probably have a shaker of salt on your table and maybe some sea salt in the kitchen cabinet.
The problem with salt is that it contains sodium and eating too much sodium may contribute to increased blood pressure, which is a risk factor for cardiovascular disease. Decreasing the amount of sodium in your diet may help to keep your blood pressure at a healthy level. Eating lots of sodium may also lead to fluid retention and bloating.
While salt is a major source of sodium, many processed foods are high in sodium too. Canned foods, frozen meals, cured meats and many snack foods contain outrageous amounts of sodium. So to keep your sodium levels in check, you need to put down your salt shaker and read Nutrition Facts labels when you shop.
The recommendation for a healthy person is to keep sodium intake below 2,400 milligrams (2.4 grams) per day. People with high blood pressure may need to stay below 1,500 milligrams (1.5 grams). One teaspoon of salt has about 2,300 milligrams sodium. Just one-quarter teaspoon has 580 milligrams and a dash of salt has around 150 milligrams.
You'll find sodium in most butter or margarine, milk, bread and other staple foods. Heavily processed foods and cured meats often have even higher amounts of sodium. Look for these ingredients on the label:
