What does the review cover?
The purpose of the review was to synthesise and summarise data on walking and cardiovascular risk.
In its review, Harvard Medical School said: “Done correctly, it can be the key to losing weight, lowering blood pressure and cholesterol, boosting your memory, as well as reducing your risk for heart disease, diabetes, cancer, and more.”
It is likely for this reason that Tom Friedman described it as a “wonder drug” in his statement.
