Long-term physical activity has an anti-aging effect

Intensive exercise prevented shortening of telomeres, a protective effect against aging of the cardiovascular system, according to research reported in Circulation: Journal of the American Heart Association.

Researchers measured the length of telomeres — the DNA that bookends the chromosomes and protects the ends from damage — in blood samples from two groups of professional athletes and two groups who were healthy nonsmokers, but not regular exercisers.

The telomere shortening mechanism limits cells to a fixed number of divisions and can be regarded as a “biological clock.” Gradual shortening of telomeres through cell divisions leads to aging on the cellular level and may limit lifetimes.

Vegetables can protect unborn child against diabetes

New evidence is emerging for how important it is for pregnant women to eat good, nutritious food. Expecting mothers who eat vegetables every day seem to have children who are less likely to develop type 1 diabetes, a new study from the Sahlgrenska Academy has revealed.

The study was performed in collaboration with Linköping University, which is conducting a population study called ABIS (All Babies in Southeast Sweden).
