Recent research shows that eating less salt and more frequent exercise can keep the brain smart. Although it did not investigate the influence of salt process intelligence, the researchers found a strong correlation between lifestyle, high sodium intake and decreased cognitive function.
The study analyzed data from a longitudinal study of nutrition and aging. Result, there is a strong relationship between sodium intake, low physical activity and decreased brain function with age. This has accounted for other factors such as level of education and overall diet.
The researchers do not claim to scrape salt gray cells in the brain causes cognitive decline, but see it as a decrease in the level of overall health. That sodium-related increase in blood pressure, impact on bone health and overall heart.
However, the influence of salt can be reduced by physical activity, especially exercise. Lead study author Carol Greenwood, a nutrition scientist and interim director of applied research at Baycrest Kunin-Lunenfeld Toronto stated, "People who are physically active are protected from adverse effects of salt, regardless of how much their sodium intake. The important thing is to keep the cardiovascular system. And the benefits of exercise will be greater than the negative effects of salt, "he said as quoted from Shine.
Dr. David Katz, director of medical studies public health at Yale University, adds, "It is reasonable that people who are active, fit and healthy as a whole, better in the 'hold' the potential dangers that are less sodium than sports."
But he cautioned, dietary sodium will directly affect cognitive function in older people. Thus, salt intake should be restricted to recommended levels antaralain reducing processed foods and better mengasup food prepared from fresh ingredients.
