to meat or not to meat?

Turns out that there may be a relationship between amounts of proteins eaten and cancer mortality rates!
But it is age dependent...

The study by Levine et al found if people 50-65 ate a diet of low protein, their rates of overall, cancer and diabetes mortality decreased. But a diet of low protein intake after 65 increased overall and cancer 
mortality!

So after 65 - eat your meat!
