I’m actually not surprised at all by the result of this study.

We know from several studies that fish 🐟 , eggs🥚, nuts 🌰 and chicken 🐔 are much healthier sources of protein than red meat 🥩.

From Cornell University:

Unprocessed red meat and processed meat consumption leads to a slightly higher risk of heart disease and premature death, according to a new study from researchers at Cornell and Northwestern University

From Harvard University:

People who eat just two servings of red meat per week may have an increased risk of developing type 2 diabetes compared to people who eat fewer servings, and the risk increases with greater consumption, according to a new study led by researchers from Harvard T.H. Chan School of Public Health.

“Given our findings and previous work by others, a limit of about one serving per week of red meat would be reasonable for people wishing to optimize their health and wellbeing” said senior author Walter Willett, professor of epidemiology and nutrition.

From Oxford University:

Red and processed meat linked to increased risk of heart disease, Oxford study shows.

Overall, the evidence from the analysis indicated that each 50 g/day higher intake of processed meat (e.g. bacon, ham, and sausages) increased the risk of coronary heart disease by 18%.

Each 50 g/day higher intake of unprocessed red meat (such as beef, lamb and pork) increased the risk of coronary heart disease by 9%.

There was no clear link between eating poultry (such as chicken and turkey) and an increased risk of coronary heart disease.
