Sources of sodium
Most of the sodium consumed is from processed and restaurant foods. Only a small amount is added during cooking while eating. People trying to eat less sodium tend to consume more than they mean to because it's in the food they buy. The National Salt Reduction Initiative is a national voluntary effort to reduce the salt in packaged and prepared foods.

Ways to consume less sodium
For tips on cutting back on sodium, you can read:
Read the nutrition facts label to learn how much sodium is in the food products you eat:
- Check the number of servings. Know how much is one serving and how many servings you will be eating if you eat it all.
- Check the amount of sodium. There are 470 mg of sodium in one serving.
- If the entire container is eaten that is 940 mg of sodium.
- Look for foods with less than 200 mg of sodium in one serving.
Some food labels state that they are "low sodium" or "sodium free". Here is what they mean:
- Sodium-free or salt free- Each serving in this product contains less than 5 mg of sodium.
- Very low sodium- Each serving contains 35 mg of sodium or less.
- Low sodium-Each serving contains 140 mg of sodium or less.
- Reduced or less sodium-The product contains at least 25% less sodium than the regular version
- Lite or light in sodium- The sodium content has been reduced by at least 50% from the regular version.
- Unsalted or no salt added-No salt is added during processing of a food that normally contains salt. However, some foods with these labels may still be high in sodium.
The Minnesota Department of Health along with it's partners, are working to increase the nutritional value of foods purchased for school lunches, focusing on reduced sodium and saturated fat, and increased whole grains, fruits and vegetables.
Minnesota, along with it's partners, will support implementation strategies of the Institute of Medicine Report on Sodium Reduction and the Minnesota Obesity Plan.
Minnesota, along with many other states, is participating in the National Salt Reduction Initiative led by the New York City Department of Health and Mental Hygiene.
