Innovative method to starve tumors

This release is available in French . Montreal, February 11th, 2009 - The development of cancerous tumours is highly dependent on the nutrients the tumours receive through the blood. The team of Dr. Janusz Rak, of the Research Institute of the McGill University Health Centre (MUHC) at the ...

Half The Girls In UK Starve To Stay Slim

As many as 50% of the teenaged girls in the UK are virtually starving themselves to stay slim, according to a research conducted by the Food Standards Agency and Sugar magazine. // Some of these girls are reported to be as young as 13 years. The findings showed that 50 per cent always skip breakfas...
