Sodium
"What is a reduced sodium intake? According to Camille Brewer, a registered dietitian and nutritionist in FDA's Office of Food Labeling, therapeutic sodium-restricted diets can range from below 1,000 milligrams (mg) to 3,000 mg a day.
"American adults, on average, eat too much sodium--between 4 to 6 grams (4,000 mg to 6,000 mg) daily," she said. "Most people would benefit from moderately reducing their sodium intakes."
Brewer advises people who are considering a sodium-restricted diet to consult a physician, dietitian or nutritionist first.
Under FDA's food labeling rules, the Daily Value for sodium is 2,400 mg. (Daily Values are a new label reference tool. See Daily Values' Encourage Healthy Diet in the FDA Consumer Special Report "Focus on Food Labeling.") FDA established this value because it is consistent with recommendations and government reports that encourage reduced sodium intakes.
Salt and other sodium compounds used in food processing are the biggest contributors of sodium to most people's diets, Brewer pointed out. (One teaspoon of salt has about 2,000 mg of sodium.)
These substances are used in food processing for preserving, flavoring and stabilizing other ingredients, she said.
"That's why the ingredient lists of canned, frozen, and other processed foods often contain the names of so many sodium compounds," she said.
Also, kosher beef, lamb and chicken have salt added.
Sodium also is present naturally in some foods, such as milk, cheese, meat, fish, and some vegetables."
