Find out how much sodium you really need, what high-sodium foods to avoid, and ways to prepare and serve foods without adding sodium.
If you're like many people, you're getting far more sodium than is recommended, and that could lead to serious health problems.
You probably aren't even aware of just how much sodium is in your diet. Consider that a single teaspoon of table salt, which is a combination of sodium and chloride, has 2,325 milligrams (mg) of sodium. And it's not just table salt you have to worry about. Many processed and prepared foods contain sodium.
See how sodium sneaks into your diet and ways you can shake the habit.
Sodium: Essential in small amounts
Your body needs some sodium to function properly because it:
Your kidneys naturally balance the amount of sodium stored in your body for optimal health. When your body sodium is low, your kidneys essentially hold on to the sodium. When body sodium is high, your kidneys excrete the excess in urine.
But if for some reason your kidneys can't eliminate enough sodium, the sodium starts to build up in your blood. Because sodium attracts and holds water, your blood volume increases, which makes your heart work harder and increases pressure in your arteries. Such diseases as congestive heart failure, cirrhosis and chronic kidney disease can make it hard for your kidneys to keep sodium levels balanced.
Some people's bodies are more sensitive to the effects of sodium than are others. If you're sodium sensitive, you retain sodium more easily, leading to fluid retention and increased blood pressure. If this becomes chronic, it can lead to heart disease, stroke, kidney disease and congestive heart failure.
Sodium: How much do you need?
The Dietary Guidelines for Americans recommend limiting sodium to less than 2,300 mg a day — or 1,500 mg if you're age 51 or older, or if you are black, or if you have high blood pressure, diabetes or chronic kidney disease.
Keep in mind that these are upper limits, and less is usually best, especially if you're sensitive to the effects of sodium. If you aren't sure how much sodium your diet should include, talk to your doctor or dietitian.
Sodium: What are the major dietary sources?
The average American gets about 3,400 mg of sodium a day — much more than recommended. Here are the main sources of sodium in a typical diet:
Tips for cutting back on sodium
Virtually all Americans can benefit from reducing the sodium in their diet. Here are more ways you can cut back on sodium:
Sodium: Be a savvy shopper
Taste alone may not tell you which foods are high in sodium. For example, you may not think a bagel tastes salty, but a typical 4-inch (10-centimeter) oat-bran bagel has about 600 mg of sodium, and even a slice of whole-wheat bread contains about 100 mg of sodium.
So how can you tell which foods are high in sodium? Read food labels. The Nutrition Facts label found on most packaged and processed foods lists the amount of sodium in each serving. It also lists whether the ingredients include salt or sodium-containing compounds, such as:
Try to avoid products with more than 200 mg of sodium per serving. And be sure you know how many servings are in a package — that information is also on the Nutrition Facts label.
Sodium: More tips to cut back
The supermarket is full of foods labeled "reduced sodium" or "light in sodium." But don't assume that means they're low in sodium. For example, a can of chicken noodle soup that claims to have 25 percent less sodium still has a whopping 524 mg in 1 cup. It's only lower in salt compared with regular chicken noodle soup that has more than 790 mg of sodium in a cup.
Here's a rundown on common sodium claims and what they really mean:
Go low and take it slow
Your taste for salt is acquired, so you can learn to enjoy less. Decrease your use of salt gradually and your taste buds will adjust.
After a few weeks of cutting back on salt, you probably won't miss it, and some foods may even taste too salty. Start by using no more than 1/4 teaspoon of salt daily — at the table and in cooking. Then throw away the salt shaker. As you use less salt, your preference for it diminishes, allowing you to enjoy the taste of the food itself, with heart-healthy benefits.comments powered by Disqus
