Will plants make you bulletproof? No. Will basing your diet on eating a great variety of whole plants still help your longevity and improve the quality of those years? Yes.
"Researchers in Norway used computer models to compare a typical Western diet -- heavy on animal-based proteins dairy and sugar – with a more ideal plant-based diet that's heavy on fruits, vegetables, beans and grains and light on animal-based proteins.
According to the models, a 20-year-old who went all-in on the plant-based diet could add 10 years to their life. Even just making a partial change could add six years of life expectancy.
An 80-year-old who started a plant-based diet could add three years to their life expectancy, according to the study, published Tuesday in PLOS Medicine."
