In other words this study used zero direct observational studies.
No one has ever fed one person a meat diet and another person meat free diet and shown there to be a increase or decreased risk of heart disease.
Daily reminder that Hong Kong has one of the highest meat consumption per person in the world And one of the highest life expectancies.
India has some of the lowest meat consumptions in the world and one of the lowest life expectancies.
So clearly meat is not the demon some of these biased studies make it out to be.
