Summary It’s important to make a distinction between different kinds of meat. For example, grass-fed and organic meat is nutritionally different than factory-farmed, processed meat.
Summary Red meat is very nutritious, especially if it comes from animals that have been naturally fed and raised. It's a great source of protein, iron, B12, zinc, creatine and various other nutrients.
Summary Some observational studies show a link between meat intake, diabetes, heart disease and death. Other studies suggest this only applies to processed meat, not unprocessed red meat.
Summary Several observational studies show that red meat eaters are at a greater risk of cancer, but larger reviews looking at the evidence as a whole show that the effect is weak and inconsistent.
Summary Observational studies cannot be used to determine cause and effect. There are many confounders in such studies, and higher-quality studies sometimes end up showing the exact opposite effect.
Summary Several randomized controlled trials indicate that the intake of unprocessed red meat does not have negative health effects. It may even have benefits.
Summary To prevent the formation of harmful substances when cooking meat, choose gentler cooking methods and avoid burning your meat.
