London: Strawberries,
the traditional summer treat, could offer unexpected health
benefits of preventing development of heart disease and diabetes,
says a study.
University of Warwick scientists have been studying the beneficial
effects of strawberries on cardiovascular health, particularly
around how they prevent the development of heart disease and
diabetes.
Paul Thornalley, professor at the Warwick Medical School, heads
the team that discovered extracts from strawberries positively
activate a protein in our bodies called 'Nrf2', which is shown to
increase antioxidant and other protective activities.
This protein works to decrease blood lipids and cholesterol, the
very things which can lead to cardiovascular problems, said a
university statement.
Eating strawberries has previously been found to counter post-meal
blood glucose and low density lipoprotein, or 'bad' cholesterol
and therefore decrease risk of diabetes and heart disease, but
this is the first time that strawberry extracts have been proved
to actively stimulate proteins that offer us protection against
disease.
Thornalley explained: " We've discovered the science behind how
strawberries work to increase our in-built defences to keep cells,
organs and blood vessels healthy and which can reduce the risk of
developing cardiovascular problems such as heart disease and
diabetes."
Screening and math modelling techniques developed at Warwick can
now take this research further to help identify the best varieties
of strawberries, how they are served or processed and how many
strawberries should be eaten for optimum health benefit.
Thornalley will be presenting these findings at the 16th biennial
meeting for the Society for Free Radical Research International (SFRRI),
Imperial College London.
