Caveat
In the results section it says "Men and women with higher intake of red meat were less likely to be physically active and were more likely to be current smokers, to drink alcohol, and to have a higher body mass index (Table 1). In addition, a higher red meat intake was associated with a higher intake of total energy but lower intakes of whole grains, fruits, and vegetables." So it's very much a lifestyle issue: The people who ate the most red meat had less healthy habits, in general.
It mentions that, during the study, average consumption of red meat declined. That's certainly true for me, as I opt for poultry or fish very often now as opposed to 25-30 years ago when hamburger was pretty much all I ate. (All we could afford back then!) But I don't fit the lifestyle profile, so I don't know what the study means for me.
