Given widely-held suspicions concerning food manufacturing processes, I think most would agree that un-processed foods are of higher nutritional quality and health safety than are ultra-processed foods.
But what ever happened to that classic alarm insisting that processed meats cause cancer and heart disease? Well, don’t they?
Not according to the fine print reflected in a recently released study in the BMJ which reports that an epidemiological association (based on food questionnaires taken over 30 yrs) has been found between ultra-processed meats and overall mortality. But here are two key conclusions buried in the study (direct quotes) …
“A higher intake of ultra-processed foods was associated with slightly higher all cause mortality, driven by causes other than cancer and cardiovascular diseases.”
“Dietary quality was observed to have a more predominant influence on mortality outcomes than ultra-processed food consumption.”
So, one might expect to see a blazing headling:
"ULTRA-PROCESSED MEAT NOT ASSOCIATED WITH EITHER CANCER OR HEART DISEASE AFTER ALL!"
Yeah, right. Of course, you wouldn’t get any such impression from CNN’s reporting on the study…
And of course the “higher risks” cited in the study are hazard ratios without making it clear what, say, an x% increase in relative risk translates into in terms of absolute risks (e.g., if a 98% of not getting a disease falls to a 97% chance of not getting that disease, this equates to a 50% increase in hazard - since the original 2% risk of getting the disease increased to a 3% chance, 1.5x times higher risk .)
If interested, here’s the study on which CNN was reporting…
Go at it, you statistics geeks.
