What does history teach us about the controversy over cholesterol? Plus: we look at the zombie myth that soccer players are dying from the COVID-19 vaccine, and we dissect a new clinical trial of colonoscopies that reports disappointing results and compare it to Ryan Reynolds and Rob McElhenney’s enthusiasm for the procedure itself!
Block 1:
(1:50) Cholesterol: conflicting animal studies at the beginning of the 1900s
Block 2:
(9:28) Cholesterol: observational studies of high-fat diets in humans, randomized trials on low-animal-fat diets, drug trials
Block 3:
(27:19) Soccer players kicking the bucket? Not so much
Block 4:
(37:47) Colonoscopies: screening recommendations, alternatives to colonoscopies, latest trial
