Eat vegetables live longer speech
Answers
Answer:
From 16 observational studies, spanning from 4 to 26 years and involving over 800,000 people, researchers from China and the United States looked at the link between fruit and vegetable consumption and mortality from a range of diseases. The findings were impressive.
For every additional serving per day of fruits and vegetables, a person’s overall mortality risk fell by about 5 percent, with a lower rate of death from cardiovascular disease being the standout link. So going from 1 serving per day to 5 servings cut a person’s mortality risk by around 20 percent compared to a similarly aged person who was struggling to get through even a banana.
Once a person was eating around 5 servings of fruits and vegetables per day, they reached the limit of benefit where eating more servings didn’t show any further health advantages. Far from a negative, this shows that such a goal of 5 servings is more achievable and lowers the hurdle to get over in the face of public health recommendations of 6 or even 7 servings of fruits and vegetables per day.
Because the research was all based on observational studies, there is still inherent bias present from the methods used to estimate fruit and vegetable consumption. Other lifestyle factors that go hand-in-hand with eating lots of these food could also explain some of the benefit. The size of the study populations used, the detailed statistical analysis done and the consistency of the findings make the conclusions strong
