Our Longevity is mainly determined by genetic factors as well as the environment we live in,with the genetic factor only representing 30% the environment factors are the main factor.
the studies made about these environmental factors contained a study about calories, it found a correlation between lower calories and longevity but only in small creatures such as mice.
However a 5 year study on 100 000 Americans showed that those who ate less meat had lower risks of dying whatever the reason during that period compared to meat-eaters
But all studies do not support this idea, they argue that the differences between the meat-eaters and the vegans are too small to make a judgement.
When will we be able then to make a clear judgement, people live longer than most animals which makes it hard for studies to cover the entire lifespan of a person which makes scientists rely on dead people’s records, these studies’s credibility depends on the participants’s honesty which is sometimes pretty uncertain, also there is no direct link between death and meat consumption or the other way around (in other words an alcoholic vegan who dies of alcoholism doesn’t mean veganism is bad for you) .
What’s the secret to longevity then ? the recipe for a healthy autumn of life according to available proofs is a healthy diet low in meat which allows us to avoid certain diseases growing up but also avoiding clear harmful habits such as smoking and alcoholism.
