Eating a low-salt food buck is better than pills

Australia University of Queensland researchers in 12 aged 55 years, mean to take 3.4 pills in patients with essential hypertension were studied. The researchers that these patients have a high salt diet, rest for two weeks to make the body cleared completely, then have a low salt diet.

Their average body mass index ( BMI ) near 33, are considered to be obese. At the beginning of the study, while taking the drug, but the average blood pressure is 146/84 ( ideal blood pressure below 120/80, if blood pressure is more than 140/90, is believed to have hypertension ). When participants have a high salt diet, their daily intake of about 7000 mg of sodium; when participants low salt diet, daily intake of about 2000 to 3000 milligrams of sodium, which is lower than the United States of America dietary guidelines for the average person the recommended amount, i.e. less than 2300 milligrams a day or about a teaspoon of salt. According to the American Heart Association said, hypertensive patients suggested that the uptake of 1500 milligrams of sodium, the average American daily intake of 3436 mg.

The results showed, compared with the high salt diet, low salt diet a week later, participants in the systolic blood pressure decreased by an average of 22.7mmHG ( higher numbers), diastolic blood pressure decrease of 9.1mmHG ( lower numbers ). In another study, British researchers have found that, a modest reduction in salt intake can reduce the Asians, blacks and whites blood pressure.

This study tested the decrease in salinity on 30 years old to 75 years old, have mild hypertension but without taking blood pressure drugs in 169 men and women of influence. Their salt intake from a daily average of 9.7 grams to 6.5 grams. This quantity is converted to about 3800 mg to 2400 mg of sodium intake ( salt and sodium salt, Rio contains 40% sodium chloride, the rest is ). Research results show that, at the beginning of the study, the participants of the average blood pressure of 147/91, having low salt diet, blood pressure dropped to an average of about 141/88.

The researchers say, reduce the addition of salt to reduce blood pressure, and other benefits. For example: in the low salt diet, calcium in urine is less, from long-term in light of, reduce the loss of calcium in urine are expected to reduce the risk of developing osteoporosis. And albumin in the urine albumin is also less, high representative of kidney damage, showed a higher risk of cvd. The researchers point out, reducing salt intake is good for everyone, even if your blood pressure is very low, also do not predispose to osteoporosis. Although only 12 of patients attending this confrontation hypertension study, but on the blood pressure lowering effect is obvious. While the fall of blood pressure level and increase of two blood pressure medications effect is the same. Not only the different population can benefit from lower salinity, reduce salt not only on blood pressure effectively, such as the protection of kidney and heart also has potential.
