Ninety percent of Americans eat way too much salt. The average American consumes approximately 3,400 milligrams of sodium per day. That is the equivalent of about 1 1/2 teaspoons.
The FDA’s Dietary Guidelines for Americans 2020-2025 recommends that individuals 14 and over consume no more then 2,300 milligrams of sodium per day. The American Heart Association is even more conservative and recommends no more than 1,500 milligrams per day “ideally” for most adults especially those with heart disease.
A healthy active body needs only 200 to 500 milligrams of sodium per day to maintain proper fluid and electrolyte balance, conduct nerve impulses and contract and relax muscles. This computes to only 0.216 to 0.540 teaspoon per day.
Did you know that whole foods contain salt naturally? That’s right. A stalk of celery may not taste salty but it contains just over 30 milligrams of sodium. One cup of artichokes contain about 160 milligrams. One half cup of cooked carrots contain 45 milligrams. One cup of tap water contains 9 milligrams of sodium. Sodium is found in the earth naturally so it makes sense that it exists in foods that get nutrients from the soil. Even if you never add another speck of salt to your food you will not be sodium deficient by eating a balanced plant based diet.
High blood pressure is the most common consequence of diets high in sodium. When we eat too much salt, the body holds on to extra water to balance things out. This extra fluid increases blood volume which then increases blood pressure. Increased blood pressure over time narrows and damages the delicate inner lining of the arteries. A low sodium diet centered around plant based eating seems to be the best way to bring down blood pressure.
But hypertension is not the only consequence. Researchers from Weill Cornell Medicine found a connection between high salt diets and decreased nitric oxide levels. Nitric oxide is an essential molecule necessary for cerebrovascular health. Low levels of nitric oxide cause protein plaque deposits in the brain associated with Alzheimer’s disease. So reducing our intake of sodium may be all it takes to prevent dementia.
If dementia wasn’t enough to convince you to shake the salt habit maybe cancer will. Excess sodium intake has been linked to stomach cancer. In fact, it seems that the risk is on the same level as heavy alcohol use. How is this possible? Well it appears that excess sodium damages the delicate lining of the stomach causing lesions which, over time, can turn cancerous.
There’s more bad news. Eating too much salt can cause calcium to be leached out of the bones leading to low bone density and osteoporosis. High blood pressure can also lead to osteoporosis by increasing the rate that calcium is lost from the bones. For every 100 milligrams of sodium you consume above and beyond the recommended, you urinate out 1 milligram extra of calcium.
In addition to adopting a diet that is centered around plant based eating pay attention to nutrition facts on food labels. A general rule of thumb is to choose foods that have no more then 1 milligram of sodium per calorie.
