Adults should aim to do between 560 and 610 minutes a week of moderate to vigorous physical activity to achieve a substantial reduction in the risk of heart attacks and stroke, suggest the findings of an observational study published in the British Journal of Sports Medicine.

This is between three to four times higher than the current public health recommendation that adults do at least 150 minutes a week of moderate to vigorous physical exercise such as brisk walking, running, or cycling.

People who are less fit need to do slightly more exercise than those who are very fit to get the same cardiovascular benefits, the study suggests.

The researchers say that the current one-size-fits-all advice on exercise may need to be changed and replaced ...

People who carry the APOE2 version of the apolipoprotein E gene are more likely to live to advanced age and are partly protected against Alzheimer’s disease, but scientists have struggled to explain why...

A supplement widely promoted for athletic performance may interfere with some of the heart’s beneficial adaptations to exercise, according to new Dalhousie University research published in Scientific Reports.

While these supplements are often promoted to support exercise performance and cardiovascular function, researchers found the combination of sodium nitrate and running prevented several beneficial cardiac improvements normally associated with exercise in females.

Those benefits included changes linked to heart structure, ventricular function and calcium handling in heart cells, which helps regulate contraction and relaxation...

A research project led by the Institute for Research in Nutrition and Food Safety (INSA) and the Faculty of Pharmacy and Food Sciences at the University of Barcelona, together with the Molecular Biology Institute of Barcelona (IBMB) of the CSIC (which stands for Consejo Superior de Investigaciones Científicas), has successfully designed and tested a gluten-degrading molecule that is a promising ally in the management of celiac disease, an autoimmune disease whose symptoms are triggered by the consumption of gluten and other prolamins found in cereals.

At present, there is a complete lack of treatment options beyond a diet free from gluten, which is difficult to maintain in Western societies where diets rely h...
