Condiments such as ketchup, mustard, soy sauce, salad dressings and prepared sauces are notoriously high in sodium

Even the health industry isn't immune to trends.

Lately, sodium seems to be the "new trans-fat." The problem is simple: We consume far too much sodium from salt and processed foods. A new study in the New England Journal of Medicine suggests that by cutting back on as little as ½ teaspoon of salt a day (1,200-1,500mg of sodium) thousands of lives could be saved by reducing the number of strokes and heart attacks.

Sodium is a mineral found naturally in the environment and therefore in our foods to some extent. We can't escape salt completely,but this isn't a bad thing; sodium is an essential mineral. Sodium regulates the total amount of water in the body and the transmission of sodium into and out of individual cells also plays a role in critical body functions.

Many processes in the body, especially in the brain, nervous system, and muscles, require electrical signals for communication. The movement of sodium is critical in generation of these electrical signals.

Throughout human history, getting too much sodium in our diets was never an issue. In fact, the kidneys, which regulate the levels of electrolytes, like sodium, potassium, chloride as well water, are well adapted to excrete excess potassium and hold on to sodium since our diets used to be much higher in potassium and lower in sodium.

Our actual physiological requirement for sodium is about 500 mg per day. It's estimated that primitive societies, in the absence of pizza and French fries, still managed to get about 1,600 mg of naturally occurring sodium. With the exception of traditional fermented foods like sauerkraut, kimchi, and tempeh, to name a few, foods are naturally very low in sodium and high-sodium foods were unheard of.

In fact, so rare was sodium that ancient cultures treated it as a valuable commodity and once traded it at a value twice that of gold. Part of a Roman soldier's pay used to be given in salt, hence the word 'salary' which is rooted in "salarium."

Whereas hypertension, or high blood pressure, has been called "the silent killer" (because it's virtually symptom-less) sodium should be referred to as "the quiet or silent food additive." Unlike other ingredients like vitamin C or potassium-based salt substitutes which are heavily regulated, the addition of sodium flows freely.

The problem lies in the fact that there is no standardization with respect to what the sodium content of a food should be and the sodium content of similar foods varies greatly across brands. Restaurant foods are exempt from mandatory labeling with respect to sodium content. At this time, any sodium reduction by manufacturers is completely voluntary.

The three main general sources of dietary sodium are:

1. Processed and prepared foods which use sodium-based additives such as sodium benzoate (a mold inhibitor) or salt to add flavoring. These include canned vegetables, soups, luncheon meats, frozen foods, cheese and fast food/take out.

2. Table salt and sea salts which are used in cooking and at the table. Seasoning salts like celery or garlic salt, as well as sodium-containing condiments. Condiments such as ketchup, mustard, soy sauce, salad dressings and prepared sauces are notoriously high in sodium.

3. Natural sources of sodium such as meat, poultry, dairy products and vegetables (sodium is in found in both animal and plant cells), although this is a much smaller contributor of our sodium intake.

Regarding our intake of sodium, the salt we add during cooking makes up about 5 percent of the total, salt added at the table accounts for about 6 percent, 12 percent comes from natural sources and over 77 percent is from processed and prepared foods. If we could cut down on the amount of added sodium we get from processed foods, there would be more than enough room in our 'sodium budget' to enjoy both the culinary and health benefits of gourmet and sea salts, both rich in minerals.

TIPS TO REDUCE YOUR SODIUM INTAKE:

Using fresh or dried herbs and spices, lemon juice, fresh garlic, and flavored vinegars to flavor foods.

Gradually decrease the amount of salt used in cooking and at the table.

Choose fresh, unprocessed foods more often.

Use condiments sparingly, and look for lower sodium versions.

Use oil rather than butter for cooking or choose salt-free butter.

Limit 'instant' foods such as noodles and cereals.

If using prepared of frozen foods, choose lower-sodium versions.

Watch out for hidden sources of sodium in the ingredient list.

Rinse canned foods like beans, tuna, or vegetables. Up to 80 percent of sodium can be reduced depending on the food type with a rinse under the tap for at least 60 seconds.

Look for unsalted snacks such as chips, pretzels, crackers, nuts, and seeds.

Read nutrition labels -- the percent DV (or daily value) for sodium is based on the Upper Limit of 2,400 mg, therefore try to choose products that offer 10 percent DV of sodium per serving.

Limit fast food and take-out meals -- use nutrition pamphlets to find lower-sodium options.

Every little bit helps and by adopting as many of the above suggestions, you can make a dent in daily sodium intake, which will greatly reduce your risk for heart disease, stroke and high blood pressure.
