Regarding the recently published study on red meat and mortality, you write:
[. . .]
they say "Red meat consumption is associated with", but their results talk about "1-serving-per-day". is the conclusion not to concern those who eat meat once or twice a week? is there a reason they didn't look at a lower frequency like this . . .
This probably isn't the forum to discuss this in depth, but what they found was that mortality increased by a factor of 1.12 per
serving of red meat per day. In principle, this factor applies to every level of red meat intake consumed by members of the study population. The risk for n
servings per day compared with intake of no red meat is 1.12n
. So, for instance, consuming red meat at every meal—ie, 3 servings per day—raises your risk of death to 1.123
=1.4 times what your risk would be if you ate no red meat at all.
The same formula works—in theory anyway—for fractional servings of red meat. For instance, the risk for 1/2 a serving per day (say, eating 1 serving every other day) would be 1.12½
=1.06 times what your risk would be if you ate no red meat at all.
