Johnston BC, Zeraatkar D, Han MA, et al. Unprocessed Red Meat and Processed Meat Consumption: Dietary Guideline Recommendations From the Nutritional Recommendations (NutriRECS) Consortium. Ann Intern Med. [Epub ahead of print 1 October 2019] doi: 10.7326/M19-1621
This from the BBC News report of the research:
The researchers – led by Dalhousie University and McMaster University in Canada – reviewed the same evidence others have looked at before.
The findings suggest if 1,000 people cut out three portions of red or processed meat every week for:
- a lifetime, there would be seven fewer deaths from cancer
- 11 years, there would be four fewer deaths from heart disease
And if every week for 11 years, 1,000 people cut out three portions of:
- red meat, there would be six fewer cases of type 2 diabetes
- processed meat, there would be 12 fewer cases of type 2 diabetes
The risks reported are broadly similar to what has been suggested before – but the interpretation of what they mean is radically different.
The researchers say:
- the risks are not that big
- the evidence is so weak, they could not be sure the risks were real
