In a model, the relative risk of mortality associated with protein intake crossed over around age 65, suggesting higher protein diets became beneficial above this age.

“in their model the uh the the relative risk um crossed somewhere you know in the 60s right in other words you know your your total mortality benefit uh was lower eating a high protein diet i think it was starting somewhere in the 60s”

“we have clinical data yeah that suggests that when when when people over the age of 65 are protein deficient versus protein significant there's a there's a there's a huge difference in muscle mass which we know is going to be associated with frailty right right pour out yeah”

“the take-home message was that low protein is beneficial up to about 65 years of age and then once you get above 65 years of age it kind of flips and people who ate a higher protein diet have lower all-cause mortality”

“The benefits of higher protein were stronger for adults older than 75.”

“So once you got to a certain age like above...I don't remember exactly, 55 or something like that, the opposite was true. So protein became more important. Protein intake was inversely correlated with mortality. So the higher the protein intake, the lower the all-cause mortality. And I think that has a lot to do with frailty.”
