New research links isolated protein to exercise and good health

Tweet

New research from the Dana-Farber Cancer Institute reveals an isolated protein, called "irisin" by the scientists, which can trigger health benefits in those who exercise.

The protein, which serves as a chemical messenger and has been shown to improve glucose tolerance and increase calorie burn, has potential as a novel treatment for obesity, diabetes and other more serious disorders including cancer, the study finds.

"There has been a feeling in the field that exercise 'talks to' various tissues in the body," said Bruce Spiegelman, a cell biologist at Dana-Farber and senior author of the report. "But the question has been, how?"

Pontus Bostrom, first author of the study, added it is exciting to find a natural substance that is connected to the health benefits that can be gained from exercise.

Exercise is important for all individuals who are focused on longevity and living a fruitful life. However, even regular exercise cannot prevent all undesirable health outcomes. Those who are worried about the financial state of their family members and loved ones may want to be prepared for the unexpected with a life insurance policy.
