Salt: Need to Re-write the Book again?
It seems that we might be able to throw out all the rule books and think again. Sp far we have found out that potatoes may not be fattening if cooked correctly, vitamin D is much more important then we thought and now we discover that salt may not be the killer we thought it was either. An article posted on September 2, 2011 at fox News explains that there may just be a pinch of doubt about salt.
We all know that High salt intake is linked to high blood pressure, or hypertension, a key risk factor for strokes, heart attacks and other cardiovascular diseases.
"Blood pressure is the biggest cause of death in the world ... and salt is the most important thing that puts it up," says Graham MacGregor, a professor of cardiovascular medicine at the London-based Wolfson Institute of Preventive Medicine and chairman of the influential World Action on Salt and Health lobby group (WASH). "Cutting back on salt gives a direct beneficial effect on the biggest cause of death in the world. That's why it's so important."
Or is it? According to two studies done in 2011 it seems that reducing salt intake may actually be harmful.
A study done in July by Rod Taylor, a professor of health services research at Exeter University analyzed 7 random trials with more then 6500 test subjects and found that although cutting back on salt did lead to slightly lower blood pressure and in one group of people with preexisting heart conditions reducing salt was associated with an increase in the likelihood of premature death.
Another study published in the Journal of the American Medical Association (JAMA) studied 3700 people whose salt intake was measured through urine samples and found that those with the lowest salt intake had the highest rate of death from heart disease, at 4 percent. People who ate the most salt had the lowest death rate from heart disease, at less than 1 percent.
More research is needed however to decide if salt is a killer or a life saver.
