Being Fit in Middle-age May Not Offer You Protection From The Risk of CVD

Moreover, it is also important to practice moderation when it comes to exercise, Morrison noted

While a lot of middle-aged adults have begun exercising, after realising its potential health benefits, new research claims that even the fittest among them are not immune to cardiovascular disease (CVD)– and they often do not have any symptoms.

The study, from the University of British Columbia (UBC) in Canada, highlights how important it is for middle-aged adults to have their doctor check their CVD risk factors, especially if they have high blood pressure, high cholesterol or a family history of CVD.

CVD refers to conditions that involve narrowed or blocked blood vessels that can lead to a heart attack, chest pain (angina) or stroke.

“We all know that exercise is good for us–it can help prevent a range of health problems and diseases, from cancer to depression,” said lead author Barbara Morrison, doctoral student at the UBC.

“However, even if you are really active, our findings suggest that you still can’t outrun your risk factors,” she added.

For the study, published in the journal BMJ Open Sport and Exercise Medicine, the team followed 798 “masters athletes” — adults aged 35 and older who engage in moderate to vigorous physical activity — running to cycling, rowing and hockey — at least three days a week.

Of the 798 athletes, 94 (11 per cent) were found to have significant CVD. Ten participants were found to have severe coronary artery disease — a blockage in their artery of 70 per cent or greater — despite not having any symptoms.

While the results may seem alarming, Morrison emphasised that it does not mean middle-aged adults should stop exercising.

Moreover, it is also important to practice moderation when it comes to exercise, Morrison noted.

“There is no evidence that pushing exercise to the limit will make you live longer or your heart stronger, but when taken to the extreme, it may have the potential to do harm,” said Morrison. (IANS)

Meal Rich in Calories Increases Risk of Diabetes

The results will be presented at the American Heart Association's Scientific Sessions 2018 in Chicago

The researchers found that women with diabetes were 27 per cent more likely to develop cancer than women without diabetes but for men the risk was 19 per cent higher.

Eating a meal rich in calories for dinner can increase the risk of diabetes as well as lead to poorer cardiovascular health, researchers have warned.

The findings showed that eating the majority of a person’s daily calories in the evening, post 6 p.m. may lead to an increased risk of developing pre-diabetes and high blood pressure, which can lead to diabetes and affect the heart.

Every one per cent increase in the number of calories eaten after 6 p.m. — about 20 calories in a 2,000-calorie daily diet — was associated with higher fasting glucose, insulin and insulin resistance, all of which are associated with an increased risk of diabetes.

Eating 30 per cent or more of a day’s calories after 6 p.m. was associated with a 23 per cent higher risk of developing high blood pressure and a 19 per cent higher risk of becoming pre-diabetic.

“There is increasing evidence that when we eat is important, in addition to what we eat and how much we eat,” said lead author Nour Makarem, a postdoctoral student at the Columbia University in New York.

“In our study we show that if you eat most of your calories before 6 p.m., you may have better cardiovascular health.

“Your meal timing matters and eating earlier in the day may be an important strategy to help lower the risk for heart disease,” Makarem said.

However, night-time eating was not associated with being overweight and obese or having central adiposity (fat).

For the study, the team analysed the meal timing of 12,708 participants, aged 18 to 76, from the Hispanic Community Health Study/Study of Latinos.
