@Mauritio said in Random, interesting studies:
It seems to come down to age as well.
Here it gets interesting: if you're under 65 and eating a high protein diet, that is strongly associated with death, cancer and diabetes . Over 65 it seems to be protective !"...aged 50–65 reporting high protein intake had a 75% increase in overall mortality and a 4-fold increase in cancer and diabetes mortality..."
https://pmc.ncbi.nlm.nih.gov/articles/PMC3988Another pointer in this direction.
Young mice experienced a 17% decrease in life span when methionine was increased, for old mice it didn't change anything.
So maybe there is an age related effect of protein on the body.
If that's true (and that's still a big if), then im starting to wonder how good Rays low protein phase was shortly before his death, given his advanced age."The lifespan of old mice was unchanged by feeding 0.05M methionine. Young mice, however, experienced a 16.9% decrease in their average lifespan and a decreased maximum lifespan when given supplemental methionine. "
https://www.sciencedirect.com/science/article/abs/pii/0531556584900494I have previously speculated that the mechanism might have to do with the immune system, since a low protein diet can lower thymus weight and that is possibly worse than additional protein in old age .
It could also have to do with heavy metals since amino acids have heavy metal cheating properties and heavy metals tend to accumulate in old age.
