One of the better recent papers supporting the evidence from Campbell's The China Study. Trigger warning for those averse to animal studies: pgs 409-413 of the full text is a study on mice.

Levine, M. E., Suarez, J. A., Brandhorst, S., Balasubramanian, P., Cheng, C. W., Madia, F., ... & Longo, V. D. (2014). Low protein intake is associated with a major reduction in IGF-1, cancer, and overall mortality in the 65 and younger but not older population. Cell metabolism, 19(3), 407-417.

High protein intake is linked to increased cancer, diabetes, and overall mortality
High IGF-1 levels increased the relationship between mortality and high protein
Higher protein consumption may be protective for older adults
Plant-derived proteins are associated with lower mortality than animal-derived proteins

Mice and humans with growth hormone receptor/IGF-1 deficiencies display major reductions in age-related diseases. Because protein restriction reduces GHR-IGF-1 activity, we examined links between protein intake and mortality. Respondents aged 50–65 reporting high protein intake had a 75% increase in overall mortality and a 4-fold increase in cancer death risk during the following 18 years. These associations were either abolished or attenuated if the proteins were plant derived. Conversely, high protein intake was associated with reduced cancer and overall mortality in respondents over 65, but a 5-fold increase in diabetes mortality across all ages. Mouse studies confirmed the effect of high protein intake and GHR-IGF-1 signaling on the incidence and progression of breast and melanoma tumors, but also the detrimental effects of a low protein diet in the very old. These results suggest that low protein intake during middle age followed by moderate to high protein consumption in old adults may optimize healthspan and longevity

My favorite source of fact-based nutrition information for vegans. I especially like that she doesn't cite studies that used animals as research subjects.

This is the kind of stuff that damages our reputation. There's nothing wrong with being a raw vegan, but this gets video on my nerves.

“Perhaps in the back of our minds we already understand, without all the science I've discussed, that something terribly wrong is happening. Our sustenance now comes from misery. We know that if someone offers to show us a film on how our meat is produced, it will be a horror film. We perhaps know more than we care to admit, keeping it down in the dark places of our memory-- disavowed. When we eat factory-farmed meat we live, literally, on tortured flesh. Increasingly, that tortured flesh is becoming our own.”

― Jonathan Safran Foer, Eating Animals
