Tomatoes are 'stroke preventers'
13 October BBC
A diet rich in tomatoes may reduce the risk of having a stroke,
according to researchers in Finland. They were investigating the impact
of lycopene - a bright red chemical found in tomatoes, peppers and
water-melons.
A study of 1,031 men, published in the journal Neurology, showed
those with the most lycopene in their bloodstream were the least likely
to have a stroke.
The Stroke Association called for more research into why lycopene
seemed to have this effect.The levels of lycopene in the blood were
assessed at the beginning of the study, which then followed the men for
the next 12 years.They were split into four groups based on the amount
of lycopene in their blood. There were 25 strokes in the 258 men in the
low lycopene group and 11 strokes out of the 259 men in the high
lycopene group.
The study said the risk of stroke was cut by 55% by having a diet
rich in lycopene.Dr Jouni Karppi, from the University of Eastern Finland
in Kuopio, said: "This study adds to the evidence that a diet high in
fruits and vegetables is associated with a lower risk of stroke.
"The results support the recommendation that people get more than
five servings of fruits and vegetables a day, which would likely lead to
a major reduction in the number of strokes worldwide, according to
previous research."He said lycopene acted as an antioxidant, reduced
inflammation and prevented blood clotting.Dr Clare Walton, from the
Stroke Association, said:
"This study suggests that an antioxidant which is found in foods such
as tomatoes, red peppers and water-melons could help to lower our stroke
risk."However, this research should not deter people from eating other
types of fruit and vegetables as they all have health benefits and
remain an important part of a staple diet."More research is needed to
help us understand why the particular antioxidant found in vegetables
such as tomatoes could help keep our stroke risk down."
