Green leafy
vegetables reduce diabetes risk
Research: Fruit and vegetable intake and incidence of
type 2 diabetes mellitus: Systematic review and
meta-analysis
Eating more green leafy vegetables can significantly reduce
the risk of developing type 2 diabetes, finds research
published by BMJ - British Medical Journal.
The authors, led by Patrice Carter at the University of
Leicester, say there is a need for further investigation
into the potential benefits of green leafy vegetables.
In the last two decades there has been a dramatic increase
in the number of individuals developing type 2 diabetes
worldwide.
Diets high in fruit and vegetables are known to help
reduce both cancer and heart disease, but the
relationship between fruit and vegetable intake and diabetes
remains unclear, say the authors.
The researchers also note that previous research found that
in 2002, 86% of UK adults consumed less than the recommended
five portions of fruit and vegetables per day, with 62%
consuming less than three portions. The study says that "it
was estimated that inadequate consumption of fruit and
vegetables could have accounted for 2.6 million deaths
worldwide in the year 2000."
Patrice Carter and colleagues reviewed six studies involving
over 220,000 participants that focused on the links between
fruit and vegetable consumption and type 2 diabetes.
The results reveal that eating one and a half extra
servings of green leafy vegetables a day reduces the risk
of type 2 diabetes by 14%. However, eating more fruit
and vegetables combined does not significantly affect this
risk. Only a small number of studies were included in the
meta-analysis and the benefit of fruit and vegetables as a
whole for prevention of type 2 diabetes may have been
obscured.
The authors believe that fruit and vegetables can prevent
chronic diseases because of their antioxidant content. Green
leafy vegetables such as spinach may also act to
reduce type 2 diabetes risk due to their high magnesium
content.
The authors argue that "our results support the evidence
that 'foods' rather than isolated components such as
antioxidants are beneficial for health … results from
several supplement trials have produced disappointing
results for prevention of disease."
In conclusion, they believe that offering tailored advice to
encourage individuals to eat more green leafy vegetables
should be investigated further.
