This led to headlines suggesting the danger was essentially linked. Ham sandwich. It seems to have come from him. Press releasewhich used ham for example to correlate processed meat intake with a 15% increased risk of developing type 2 diabetes over ten years.
The study found that this risk was linked to eating an additional 50 grams of processed meat per day, which is the equivalent of two slices of ham. Thus a useful example is picked up by the media because the foremost reason, perhaps ignoring a number of the necessary messages coming from the study.
