then took saliva and tongue coating samples to measure bacteria

lower among yoghurt eaters.
Dr Nigel Carter, chief executive of the British Dental Health
Foundation, said: "The foundation has long been drawing
people's attention to sugar-free yoghurts as a healthy snack,
so it is pleasing to hear that it may have oral health benefits
we were previously unaware of.
consumption of sugary snacks is the principal cause of tooth
decay, which can cause a great deal of pain and discomfort.
this research is still in the early stages there is no doubt
that sugar-free yoghurts provide a much healthier alternative
to sweets and chocolate, and we would encourage snackers to
incorporate them into their diet."
four people suffer from bad breath regularly, while 19 in
20 are affected by gum disease at some point in their lives.
Dr Carter stressed that the best way to beat bad breath was
by adopting a good oral health routine.
brushing twice-a-day with fluoride toothpaste, cutting down
on the frequency of sugary snacks and drinks, flossing daily
and visiting a dentist regularly.
breath' clue to lung disease
People with lung diseases have bad breath, according to scientists
in the United States. Researchers at the University of Virginia
say people with conditions like asthma and cystic fibrosis
have highly acidic breath.
more, the acidity of their breath rises depending on how severe
their condition is.
in the European Respiratory Journal, they said a simple breath
test could help doctors spot these diseases.
They said doctors should be able to distinguish between healthy
patients and those with lung diseases quite easily.
because healthy people have breath which is slightly alkaline.
said the acidic breath associated with people with lung diseases
may be caused by the
overproduction of acids in the lung.
this overproduction may even cause some of the symptoms associated
with these diseases.
Hunt and colleagues said breath tests were a simple and reliable
way of detecting lung diseases.
100 healthy patients to breathe into a disposable breathalyser.
provided four samples a day for seven consecutive days.
the researchers could measure the pH levels or acidity of
over 900 breath samples.
that their pH levels remained relatively stable and slightly
in contrast to people with lung diseases whose readings fluctuate
but remain acidic.
found that the breath test was more reliable than alternative
approaches, such as taking saliva samples from patients' mouths.
found that breath tests were as accurate as taking samples
from the back of patients' throats.
in the European Respiratory Journal, they said the procedure
was "extremely simple to perform, inexpensive and robust".
they have shown that pH levels rise if patients receive proper
test which reliably measures pH levels could transform the
way these patients are diagnosed and monitored.
moment, UK doctors use spirometers to diagnose lung diseases.
These machines measure the capacity and efficiency of the
lungs by getting patients to exhale into them.
a recent study found that just 60% of NHS GPs have access
to this equipment.
