It probably won’t come as a surprise, but walking more and eating more fiber are probably good for your heart. That’s the conclusion of two new studies, but because the studies relied on observational data it should be emphasized that they are incapable of demonstrating cause and effect. And it’s by no means clear that most people are willing to undertake the effort needed to achieve effective lifestyle changes like these.
In the first study, published in the Lancet, researchers analyzed data from 9,300 people with impaired glucose tolerance (and therefore at high risk for developing diabetes) and with existing cardiovascular disease or at high risk for CV disease.
In the second paper, published in BMJ, investigators performed a systematic review of studies examining the effect of dietary fiber on cardiovascular and coronary heart disease.
