Researchers from Australia revealed that a diet full of salt will quickly stop the dilation of blood vessels, even though the person has normal blood pressure. Damage to blood vessels can occur in just 30 minutes from the time he ate.
Kacie M Dickinson and colleagues from the Commonwealth Scientific and Industrial Research Organitation in Adelaide involving 16 healthy subjects in this study. Participants were divided into two groups, of which the first group given tomato soup with low salt levels while the second group was given the same tomato soup with salt levels 10 times as much.
After that, the researchers measured the arteries (blood vessels) participants using ultrasound. Obtained arterial participants who ate more salt will damage that makes the blood flow is limited. This effect will begin to decrease within about two hours. These results have been published in the American Journal of Clinical Nutrition.
"The most important of these studies add to evidence that sodium is able to provide direct chronic effects on blood vessels," said Dr. Sahil Parikh, a cardiologist at University Hospitals Case Medical Center.
When the heart pumps blood through the arteries to produce nitric oxide gas that causes artery walls to relax and allow it to narrow or widen, according to circumstances.
Scientists believe that excess salt can inhibit the release of nitric oxide that makes the artery walls to harden in a short time. Therefore people potentially or have risk factors for hypertension and heart must go on a diet of salt or sodium.
Parikh advise people to follow the guidelines recommended in the consumption of salt per day. While the people who work hard and exercise levels may require a slightly higher salt in his diet pattern.
Recommended intake of salt given health experts every day based on age is
0-6 months 1 gram
7-12 months 1 gram
1-3 years 2 grams
4-6 years 3 grams
7-10 years 5 grams
11-14 years 6 grams
Adult 6 grams.
