I'm concerned about milk because of the IGF-1 and other growth factors that might be in it. And also, because it feels unnatural for humans (or any adults) to drink it?
yup, the human digestive system is not designed to digest other animals' milks
With meat, I'm concerned about the arachidonic acid (long-chain polyunsaturated omega-6). And also, other things that make meat be widely regarded as unhealthy.
I think the most widely publicized problem among people is the saturated fat, which has proven itself to be very beneficial at 10-20% of the diet
But saturated fat isn't that bad in comparsion to the other things in these foods, or is it? If so, why?
there are many things that can be wrong w/ beef and milk, such as growth hormone etc...(as you pointed out) but preventive measures are hard and near impossible to take...I would say out of the two, beef is better IMO.
