We're all confused about Red Meat. Here's Why.

Why is red meat so controversial? Heart disease or heart-healthy? Grass-fed or grain-fed? Established or undetermined? Beef, lamb, bacon or ham?

A look at the scientific evidence on the health impact of red meat.

forget whether you love or hate red meat. what is the health effect of eating red meat on cvd

higher consumption of red meat associated with risk of CHD

increased risk of death due to different causes incl. HD associated with red meat intake

whats our level of certainty regarding effect of red meat on CVD? Very low.

red meat includes bacon, salami, beef jerky, etc as well as steaks. maybe processed red meat is a problem but steaks are fine

higher intake of total red meat or red meat excluding processed meat, both were significantly associated with risk of CHD. Both processed and unprocessed red meat associated with mortality incl. HD

higher consumption of unprocessed red meat associated with 9% higher risk of ischemic heart disease per 50g eaten daily, about a quarter of a 8oz steak

People who eat more red meat also tend to exercise less, smoke more, drink more alcohol, etc.

maybe those factors are the real problem and red meat is an innocent bystander?

associations with red meat were stronger after other risk factors removed from the equation. mortality associated with red meat was stronger in non/former smokers, in people with normal BMI, and non/mild alcohol drinkers

do ultraprocessed food and animal foods incl. red meat have independent health effects?

red meat associated with risk even after ultraprocessed food taken out of the equation. association btw red meat and disease can’t be simply pinned on junk food

if red meat is an innocent bystander we might expect red meat to be less harmful in the context of a healthy diet. But association between unprocessed red meat and CVD was stronger in participants who consumed a higher-quality diet

red meat without junk food showed if anything stronger associations

increased risks associated with red meat may be partly accounted for by heme iron and heme iron is very high in red meat

a candidate mechanism for the effect of red meat
