Two cups of tea per day can keep
risk of ovarian cancer away
London: There's some good news for
ladies! A new study has shown that women, who drink two cups of tea a day, face
one-third less risk of developing ovarian cancer.
Researchers at the University of East
Anglia (UEA), studied the dietary habits of 171,940 women aged between 25 and
55 for more than three decades, and found that both tea, and citrus fruits and
their juices had the capacity to significantly lower the risk of developing the
disease, the Daily Express reported.
Lead researcher, Prof Aedin Cassidy
said they discovered that the women who consumed foods high in flavonoids had a
significantly lower risk of developing ovarian cancer, which is also known as
the "silent killer" as its symptoms emerge after the disease has
advanced notably.
They found that compounds like tea and
citrus fruits and juices contained flavonoids, powerful compounds with strong
disease-fighting properties, and that a couple of cups of tea, particularly
black tea, per day, could reduce the risk by 31 percent.
The research was the first to broadly
examine the six major flavonoid subclasses present in the normal diet with
ovarian cancer risk, and the first to investigate the impact of polymers and
anthocyanins.
Earlier in 2012, researchers from the
Curtin University in Perth, Australia, had found that drinking tea from an
earlier age could slash the risk of ovarian cancer in old age.
The study is published in the American Journal of Clinical
Nutrition.

Hair disorder could signal dental
decay
Washington: If you are experiencing
hair fall problems, your teeth may require extra care as researchers have found
that hair disorder could increase risk of dental decay.
Keratins, proteins associated with
strong hair, are important for tooth enamel, the findings showed.
Individuals with mutations in hair
keratin genes are prone to cavities, the findings showed.
The researchers found that tooth enamel
from individuals with keratin mutations had abnormal structure that resulted in
weakness.
"Our results identify a genetic locus that influences
enamel structure and establishes a connection between hair disorders and
susceptibility to dental caries," said Maria Morasso from National
Institutes of Health in the US.
Tooth enamel is the
hardest substance in the human body and has a unique combination of hardness
and fracture toughness that protects teeth from dental caries, the most common
chronic disease worldwide.
"Epithelial hair keratins, which are crucial for
maintaining the integrity of the sheaths that support the hair shaft, are
expressed in the enamel organ and are essential organic components of mature
enamel," the researchers said.
The study involved genetic and intra-oral examination data
from 386 children and 706 adults.
The researchers found that individuals harbouring known hair
disorder-associated polymorphisms in the gene encoding keratin 75 (KRT75),
KRT75A161T and KRT75E337K, are prone to increased dental caries.
A functional keratin network is required for the mechanical
stability of tooth enamel, the findings showed.
The study appeared in the Journal of Clinical Investigation.
