Our bodies get Vitamin D from the sun, but as dermatologist Richard Weller suggests,sunlight may confer another surprising benefit too.
New research by his team shows thatnitric oxide, a chemical transmitter stored in huge reserves in the skin, can be released by UV light, to great benefit for blood pressure and the cardiovascular system. What does itmean? Well, it might begin to explain why Scots get sick more than Australians ...
Child trafficking can be likened to modern-day slavery. Trafficking is not just an issue that happens to people in other countries. Cases of human trafficking have been reported in all 50 U.S. States.
Three independent experts help explain how breakfast may be involved in
shape management. They gathered as part of a satellite symposium held at
the Queen’s University of Belfast. We invite you to watch the video
recap below and review their findings.
The observational evidence:
Dr. Margaret Ashwell, Ashwell Associates
There is consistent scientific evidence of an association between
breakfast cereal consumption and a healthy weight in adults and in
children. But, to date, there is limited evidence for any plausible
biological mechanisms that would point to it being a causal
relationship.
There is however new research that indicates there is something
worth investigating in the effect of the breakfast meal and what we can
be sure of is that, although it is important to follow a healthy,
balanced diet along with plenty of exercise, breakfast really is the
most important meal of the day.
The physiological reasons:
Dr. Jonathan Johnston, University of Surrey
Diet, metabolism and circadian rhythms are closely linked. It
appears that we may be 'when we eat' as well as 'what we eat'. Circadian
clocks are now known to be present throughout the body, including in
key metabolic tissues. Recent studies have begun to decipher the
physiological role of these clocks and thus physiological mechanisms
that underlie daily rhythms in metabolism and postprandial response.
A second line of research is investigating how appropriately timed
food intake can actually reset the timing of circadian rhythms. Data
from this work suggest that the use of timed dietary interventions may
confer many benefits; from improving the health of society to minimising
the adverse effects associated with shift work and jet lag.
The plausible mechanisms:
Dr. Sue Reeves, University of Roehampton
Since the evidence available is unable to clarify the mechanisms
that link BMI with regular breakfast consumption a recent study at the
University of Roehampton aimed to explain this association with an
experimental trial to establish underlying differences between breakfast
eaters and breakfast skippers that were normal weight and overweight.
Measures of resting metabolic rate (RMR), dietary induced
thermogenesis (DIT), blood glucose, hunger, physical activity and
‘morningness’ (an indicator of personal circadian rhythm) were
repeatedly made in the laboratory. Results thus far have indicated
differences in morningness, hunger levels and caffeine consumption
between breakfast skippers and non-breakfast skippers.
Overweight breakfast skippers also appeared to have lower RMR and
blunted DIT following breakfast whilst exhibiting greater levels of
physical activity. Physiological and behavioural predispositions that
determine breakfasting habits and responses to breakfast will be
explored.
Our medical systems are broken. Doctors are capable of extraordinary (and expensive) treatments, but they are losing their core focus: actually treating people.
Doctor and writer Atul Gawande suggests we take a step back and look at new ways to do medicine -- with fewer cowboys and more pit crews.
When you're getting medical treatment, or taking part in medical testing, privacy is important; strict laws limit what researchers can see and know about you.
But what if your medical data could be used -- anonymously -- by anyone seeking to test a hypothesis? John Wilbanks wonders if the desire to protect our privacy is slowing research, and if opening up medical data could lead to a wave of health care innovation.
