<p>New study examines link between brain cortex and food buying habits</p>
<p>MONTREAL: Will that be a pizza for you or will you go for a salad? Choosing what you eat is not simply a matter of taste, conclude scientists in a new study at the Montreal Neurological Institute and Hospital of McGill University and the McGill University Health Centre. As you glance over a menu or peruse the shelves in a supermarket, your brain is making decisions based more on a food’s caloric content. </p>
Obesity rates continue to skyrocket around the world. The Lancet medical journal recently reported that the number of overweight and obese people doubled over the past 30 years, reaching 2.1 billion worldwide in 2013, despite public health campaigns and other measures that promote healthy eating and exercise.
Rare genetic mutation linked to psychiatric illnesses, obesity
B Charlie Fidelman, GAZETTE Health Reporter October 8, 2012
MONTREAL — Grounding chronic illnesses and mental disorders in human DNA is like trying to tease out a giant riddle that’s complicated by the intricate relationship between biology and behaviour.
McGill researchers have identified a small region in the genome that conclusively plays a role in the development of psychiatric disease and obesity. The key lies in the genomic deletion of brain-derived neurotrophic factor, or BDNF, a nervous system growth factor that plays a critical role in brain development.
