I think it is still best to err on the side of caution for a number of reasons. One is that not all red meat is equal in quality. For example, beef from cafo's where they heavily does with antibiotics and mostly feed them corn and soy is not the same as grass fed and finished. But another reason is simply your individual health profile. Most people know that the Inuit and other northern people's have adaptations to allow them to handle much higher levels of meat and fat. Maybe you can't handle as much as other people can. I only read the abstract but I saw nothing about the risk of obesity and diabetes there, but clearly in rich countries, we eat too much meat. Lastly there is the environmental reasons. We can't feed everyone the same amount of meat that we in the rich countries eat. So sooner or later we will have to get used to less.
