It has been well established that high sodium intake can trigger sodium retention, which can result in increased fluid volume and high blood pressure. As we know, high blood pressure is directly related to the risk of heart disease and stroke.
The following list represent 6 negative health consequences of excessive sodium intake:
1) atheroerosis/ arteriosclerosis
2) kidney damage
3) Increased risk of dementia
4) Increased incidence of gastric cancer
5) Increased calcium excretion
6) Left ventricular enlargement
The dietary guidelines for Americans 2010 recommend that sodium intake be less than 1,500 mg/day. This is a decrease from the 2,300 mg/day 2005 dietary guidelines.
Keep this mind: Just 1 fast food biscuit/sandwich with egg and sausage has 1,210 mg of sodium.
What we eat has consequences...rather those are positive or negative is simply a matter of consuming nutrient dense foods.
