Eating foods that contain common preservative food additives may increase the risks of high blood pressure and cardiovascular disease, according to research published in the European Heart Journal.

The research was led by Dr. Mathilde Touvier, a research director at INSERM (the French National Institute for Health and Medical Research), and Anaïs Hasenböhler, Ph.D. student, both from the Nutritional Epidemiology Research Team at the Université Sorbonne Paris Nord and Université Paris Cité, France.

Ms. Hasenböhler said, “Food preservatives are used in hundreds of thousands of industrially processed foods...

For real heart protection, the weekly exercise number climbs far beyond current advice

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 ...

Longevity-linked APOE2 gene variant helps neurons repair DNA and resist aging

Longevity-linked APOE2 gene variant helps neurons repair DNA and resist aging
This image is an artistic representation of how APOE2 promotes resilience to cellular senescence maintaining the integrity of DNA and the nuclear envelope. We show a neuron protected by APOE2 represented as orange dots across the cell, with a blue mesh representing the resistance to senescence. We highlight in golden the integrity of the nucleus and the protected genome. Credit: Ella Maru for the Buck Institute

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...

Popular workout supplement may blunt heart benefits of exercise in women

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...
