This large study of people following different healthy diets showed that most added around 2 years of life on average.
Most interesting was that when they broke down what part of the diets was having the biggest impact, fiber was the common denominator.
Fiber can be thought of as the scaffolding that holds fruits, vegetables, and whole grains together. In the body it is fuel for beneficial bacteria in the gut and it is also an important part of detoxification.
A recent study suggests that 5 healthy dietary patterns are associated with improved longevity, and close adherence to these eating plans could add up to 3 years life expectancy.
