The risk-benefit relationship between air pollution and physical activity is an important public concern because more than 91 percent of people worldwide live in areas where air quality does not meet World Health Organization (WHO) guidelines.
Researchers studied more than 140,000 non-hypertensive adults in Taiwan and followed them for an average of 5 years.
Researchers classified the weekly physical activity levels of each adult as inactive, moderately active, or highly active.
Researchers also classified level of exposure to fine particulate matter (PM2.5) as low, moderate and high.
PM2.5 is the most commonly used indicator of air pollution.
High blood pressure was defined as 140/90 mm Hg.
Overall, people who are highly active and exposed to low levels of pollution had a lower risk of developing high blood pressure.
People who were inactive and exposed to highly polluted air had a higher high blood pressure risk.
Each increase in PM2.5 level was associated with a 38 percent increase in risk of incident hypertension, whereas each increase in physical activity level lead to a 6 percent lower risk of hypertension.
This suggests that reducing air pollution is more effective in preventing high blood pressure.
The benefits of regular physical activity held up regardless of pollution level.
People who exercised moderately had a 4 percent lower risk of high blood pressure than those who didn't exercise.
Following a study on hypercholesterolemia, researchers have suggested that people with the condition should eliminate carbohydrates from their diet instead of fats. Familial hypercholesterolemia is a genetic disorder that causes people to have cholesterol levels 2-4 times higher than the average person. Organisations, including the American Heart Association, have suggested they avoid eating food from animal sources, such as meat, eggs, and cheese, and to avoid coconut oil. An international team of experts on heart disease and diet, including five cardiologists, reviewed dietary guidelines for people with familial hypercholesterolemia. They say they couldn't find any justification for health experts to recommend a low saturated fat diet. Diamond and his co-authors say following a low-carb diet is most effective for people at increased risk of heart disease, such as those who are overweight, hypertensive and diabetic. Their findings are consistent with another paper recently published in the "Journal of the American College of Cardiology," which provided strong evidence that food that raises blood sugar, such as bread, potatoes and sweets, should be minimized, rather than tropical oils and animal-based food.
