Mussels 'helped arthritic dogs'
Dogs' arthritis was eased, claim researchers !
The symptoms of a group of dogs crippled by arthritis were eased by a diet
enriched with extracts from the green-lipped mussel. But arthritis experts in
the UK say there is little scientific evidence to show that it works in humans,
despite its years in favour as a complementary therapy for the condition.
Arthritis is a common problem in older dogs, and the study involved feeding 32
mongrels either a "dummy" placebo or a powder made from the mussels.
This was added to their normal food.
Green-lipped mussels are a rare commodity !
After
six weeks, the dogs were examined for visible signs of lameness, and levels of
joint inflammation. This "total arthritic score" had improved in four
out of five dogs given the mussel extract. Half of the dogs given the treatment
had improved by at least half. In those not given the supplement, the scores had
deteriorated slightly. Dr Linh Bui, who conducted the trial, said: "We've
been feeding this diet to dogs with arthritic symptoms and they improved
amazingly." Sadly, once the dogs stopped eating the supplement, their
symptoms worsened once more. However, arthritis experts stressed that even
though the extract appeared to work in a tiny study involving dogs, it was less
certain whether it would work for their owners.
The mussel extract is already marketed in the UK
Even
Dr Bui conceded that the varying diet of humans could interfere with its
working. A spokesman for the Arthritis Research Campaign said: "There have
been studies which suggest a benefit, and an equal number which suggest no
benefit. "Although people do take green-lipped mussel we don't think there
is any evidence to show that it works - it could all be in the mind." The
active ingredient of the mussels remains unclear even to its proponents,
although a fatty acid called icosatetranoic acid is one candidate. Extracts of
the mussel are already marketed in the UK as a complementary therapy for
arthritis. Other research suggested that they might have cancer-fighting
properties.
