Killer Carbs: Scientist Finds Key To Overeating As We Age
ScienceDaily (Aug. 22, 2008) =97 A Monash University scientist has
discovered key appetite control cells in the human brain degenerate
over time, causing increased hunger and potentially weight-gain as we
grow older. The research by Dr Zane Andrews, a neuroendocrinologist
with Monash University's Department of Physiology, has been published
in Nature.
Dr Andrews found that appetite-suppressing cells are attacked by free
radicals after eating and said the degeneration is more significant
following meals rich in carbohydrates and sugars.
