Need another reason to build exercise into your week, month and so on? Here comes one, with a new analysis of the research suggesting that those who are the most aerobically fit for better heart health have almost half the risk of dying from cancer compared to those least fit. The study was published in the Annals of Oncology.
With heart disease and cancer the top two causes of death in the US, the analysis adds to a growing body of evidence that people can protect against top diseases with similar healthy lifestyles.
This study focused on a physical fitness indicator often used for heart health called cardiorespiratory or aerobic fitness. In order to produce energy, our exercising muscle cells need to pull oxygen from the blood. Cardiorespiratory fitness measures how well muscles get oxygen when exercising at a high intensity by looking at the maximal volume of oxygen used (called the VO2 max).
Cardio or aerobic exercises that get your heart rate up and your blood moving – jogging, biking and dancing — help improve your cardiorespiratory fitness. Continue reading →
Eating high amounts of red meat increase risk of colorectal cancer while fiber-filled food reduces the risk, AICR research shows. Now comes a study that offers one possible explanation for both links, finding that diets high in red meat and a type of non-digestable fiber have opposite effects on a group of genetic molecules.
Study researchers focused on a type of fiber called resistant starch. Our bodies don’t digest resistant starch in the small intestine. Then in the gut, bacteria convert resistant starch into the compound butyrate. In lab studies, this compound protects against colon cancer.
For the study, 23 participants, ages 50 to 75, switched between two types of diets. In one diet each person was given 300 grams — about 10 ounces — of raw lean red meat a day. That’s about the equivalent of a cooked 8 ounce burger. The other diet had the same red-meat content plus a butyrate resistant starch formulation. Each person was on one diet for four weeks then after a four-week washout period, switched to the second diet for four weeks. Continue reading →
Last week, yet another independent scientific study added to the robust evidence that following AICR’s 10 Recommendations for Cancer Prevention is powerfully protective against a great many diseases and conditions, not simply cancer alone.
Previous independent studies have shown that our Recommendations protect against breast cancer and prostate cancer, reduce risk for cancer death, help people live longer, and improve cancer survivors’ physical and mental health. This latest study is a welcome addition to the ever-growing evidence that our advice maximizes your chances for leading a long and healthy life.
