If you really want to live a longer life eat every other day. There is no reason to eat food everyday. Our bodies are not designed to eat massive amounts everyday, thats why we have a huge problem with diabetes. We store fat for a reason. We are meant to go long periods of time without food.
Every animal on earth will have their lifespan increased significantly by calorie restriction.
To put it simply eating = aging.
Good idea, but I do not think food is the only cause of aging. Because there are many environmental factors and special habits that affect the age.
Such as smoking and exercise.
