Adverse effects

very low meat intake associated decreased mortality^[1]
2 decades of adherence to very low meat diet associated with a 3-6 year increase in life expectancy
protective effect of very low meat diet attenuated after 80 years of age^[1]
high animal protein diet associated with increased mortality
high plant protein intake associated with decreased mortality, especially when other lifestyle risk factors are favorable^[2]
nitrate-cured meat products associated with mania in humans^[3]

FDA has approved human food made from cultured animal cells^[5]
- cells obtained from livestock, poultry, seafood, or other animals may be used in the production of human food^[5]
