Ottawa, October 23, 2016: Even if you are up to 20 per cent less fit than your population average, it is sufficient to prevent risk factors like diabetes, hypertension, obesity that affect people with heart disease, finds a study.

Physical inactivity along with risk factors like depression, diabetes, dyslipidemia, hypertension, obesity, excess weight, and smoking may lead to heart disease, which is one of the leading causes of death in the world, representing 31 per cent of global mortality, the study says.

To measure the impact of physical fitness on heart disease risk factors, the researchers selected 205 men and 44 women with heart disease, including coronary artery disease, stroke, congestive heart failure, and heart valve disease, and had them undergo a cycle ergometer (stationary bike) stress test to determine their fitness level.

The results showed that normal physical fitness, even up to 20 per cent below the population average, is sufficient to have a preventive effect on five of the eight risk factors affecting people with cardiovascular disease–abdominal circumference, diabetes, hypertension, obesity, and excess weight.

“It is common to meet people entering a cardiac rehab centre who are totally out of shape and whose exercise is irregular or non-existent, which has a harmful effect on general and cardiovascular health,” said Daniel Curnier, a professor at the University of Montreal, Canada, said in a statement.

The easiest way to achieve normal physical fitness is to follow the recommendations of the World Health Organization — 150 minutes per week of moderate exercise or 75 minutes of vigorous exercise, the study suggested.

The results have also demonstrated the importance of a good fitness level, before and after a heart attack, to produce the preventive effect on depression.

The study sheds new light on the overall role of physical fitness in the development of cardiovascular risk factors in patients with cardiovascular disease. (IANS)

  • Regularly consuming whole grain foods such as barley, brown rice, millet, oatmeal and rye may help lose weight
  • It also decreases the risk of heart disease and diabetes, a study has claimed.

Why should you eat more whole grains? Here is all you need to know

The findings showed that study participants who ate whole grains had less inflammation, particularly in overweight people, which increases the risk of developing Type 2 diabetes.

Further, participants were also found to eat less when whole grain products were on the menu because whole grain consumption causes satiety.

Importantly, having a whole grain diet helps lose weight, as compared to refined grains — rich in starch, gluten and devoid of natural fiber.

“Our analysis confirmed that there is a sound scientific basis for the dietary recommendation to eat whole grains. This may particularly apply to people who are at increased risk of developing cardiovascular disease or Type 2 diabetes,” said Tine Rask Licht, professor at the Technical University of Denmark.

Additionally, the researchers used DNA sequencing to analyze stool samples from the participants in order to examine whether the different diet types affected the participants’ gut bacteria composition.

Overall, the analysis did not show major effects of the dietary grain products on the composition of the lose weight.

“However, even though the analysis did not reveal significant changes in the average gut microbiota after whole grain consumption, it may well be that the individual components of our gut microbes has an impact on the individual reaction of our body to dietary whole grains,” Licht explained.

For the study, described in the journal Gut, the team included adults at risk of developing cardiovascular disease or Type 2 diabetes. The participants were divided randomly into two groups, with whole grain diet and refined varieties for eight weeks.(IANS)
