Sodium plays a key role in balancing the levels of fluid in our bodies by signaling to the kidneys when to retain water and when to get rid of it. A high-sodium diet can interfere with this delicate process and reduce kidney function. Less water removed, may lead to higher blood pressure. Excess strain on the kidneys can lead to kidney disease or exacerbate kidney problems.
This will lead to many serious conditions, such as stroke and heart failure. Although blood pressure increases naturally with age, according to the American Heart Association, reducing your salt intake can help prevent your blood pressure from increasing too much.
About 75 percent of the sodium we consume comes not from the salt shaker, but rather in processed and restaurant food.
A 2011 Australian study found that the brain responds to sodium similar to how it does for substances such as heroin, cocaine, and nicotine.
Canadian study on 1,200 older sedentary adults with normal brain function found that over the course of three years, high-sodium diets were linked to increased risk of cognitive decline. This result was “independent of hypertension and global diet quality”
Excessive salt in the diet can cause swelling in the hands, arms, ankles, legs, and feet, caused by fluid retention.
Look for the labels of any product and steer away of the high salt content. Just a thought.
