Meat diet harmful as smoking

A new study has revealed that smoking, diets rich in animal products, and alcohol have the strongest correlations with cancer incidence rates.

This study is an ecological study in which incidence rates for the various types of cancer for males and females from 87 countries with high quality cancer incidence rate data as well as all 157 countries with cancer incidence rate data were compared statistically with indices for various risk modifying factors.

Dietary supply data were obtained from the Food and Agriculture Organization of the United Nations. Data for various periods back to 1980 were included since there is generally a lag of up to 20 years between dietary changes and peak cancer rates.
