Anti-smoking efforts have saved 8 million lives

Fifty years ago, Surgeon General Dr. Luther Terry made a bombshell announcement: "The strongest relationship between cigarette smoking and health is in the field of lung cancer. There is a very strong relationship, and probably a causal relationship, between heart disease and cigarette smoking."

It was the first time a surgeon general said that smokers had a 70% greater chance of death and that heavy smokers were 20 times more likely to develop lung cancer than non-smokers.

The landmark report launched one of the biggest public health campaigns in U.S. history, including warning labels on cigarettes, cigarette advertising banned on TV and radio, graphic public service announcements, and anti-smoking laws.

Now a new study in this week's Journal of the American Medical Association - which has devoted its entire issue to tobacco and smoking - estimates that tobacco control efforts since the first Surgeon General's report have added 20 years of life for 8 million Americans. Without tobacco control, half of those Americans would have died before the age of 65.

Red light, green light: Food choice made easier

Healthier items were also placed in prime locations throughout the cafeteria, while unhealthy items were pushed below eye level.

The "Green Light, Red Light, Eat Right" method is a favorite among experts fighting childhood obesity. But doctors at Massachusetts General wanted to know if the colors could really inspire healthier eating habits among adults long-term.

The results of their study were published Tuesday in the American Journal of Preventive Medicine.
