Those phytochemicals ? natural plant-based compounds that give fruits and vegetables a reputation as healthy food ? could be unhealthy if consumed in high doses in dietary supplements, teas or other preparations, scientists in New Jersey have concluded after a review of studies on the topic.
Scientific evidence increasingly links arterial calcification to the presence of nanosized particles ?o so small that some scientists question whether a nanoparticle can live and, if so, play a viable role in causing disease.

Being obese increases the risk of breast cancer in post-menopausal women, shortens the time between return of the disease and lowers overall survival rates. Italian researchers speaking at Experimental Biology 2007 in Washington, DC, now report evidence on how leptin, a hormone found in fat cells, significantly influences breast cancer development and progression in mice.
