Re: Cutting back salt may be worse for heart health: Study

[Guest guest]

What has more impact in health a reduction of 3.5% of mm of Hg in a man that has

systolic blood pressure of 150 that means a reduction to 145 (rounded up) or an

increase of 5 mg (the 2.5%) of cholesterol in a person that has 200mg/dL to

205mg/dL?

When they reduced the salt what food replacements did these patients chose?

I don't have access to the full paper,if anyone has please send me. I would like

to review the methodology used and which studies were included.

cardiovascular disease and stroke. To find out for sure, researchers reviewed

167 salt studies, but looked at other factors related to heart health besides

blood pressure.

pressure as expected, but it caused a 2.5 percent increase in cholesterol and a

7 percent increase triglycerides. The researchers also found dietary salt

reduction caused kidneys to produce more enzymes and hormones that regulate the

body's salt levels, which in turn cause the body to retain more salt. All these

increases were considered significant, and could be harmful for cardiovascular

health, the researchers said.

might then raise your cholesterol, " Dr. Tara Narula, a cardiologist at Lenox

cardiologists who would say that based on this study that they would not

recommend low-sodium diets to people, especially those that have hypertension

and heart failure. "

sodium intake for Americans of 2,300 mg a day and also recommends that certain

groups consume 1,500 mg or less each day, including Americans over 51 years old,

African-Americans, and people with hypertension, diabetes, or chronic kidney

disease.
