When overwhelmed by nutrition headlines that offer contradictory advice and dire warnings, Prof. Richard Feinman recommends going directly to the scientific literature. “Those of us trained in the physical sciences are astounded at the confusion and poor scientific logic that are rampant,” he writes. Using common sense and intuition, he suggests, can go a long way when determining whether the findings conveyed in a headline or paper are true or bogus. Here, he offers a guide for understanding the data in scientific literature. He then provides an example in which he uses the guide to evaluate the famous study by Rashmi Sinha, et al., which claimed higher consumption of red meat is associated with higher cancer risk.
