The incidence of breast cancer has increased at an alarming rate. In 1950, one in twenty women got breast cancer. In 1960, one in fifteen women got breast cancer. Now, it's one in eight! There is a strong connection between toxic chemicals and breast cancer. A breast cancer study in Israel showed the concentration of toxic chemicals was higher in the malignant breast compared to the normal breast. After release of this study, Israel banned some of the chemicals found in highest concentrations including DDT and PCB. As a result, the breast cancer rates decreased. And the rate of breast cancer decreased even in women that had an increase in other risk factors, such as high alcohol and fat consumption, and low fruit and vegetable consumption.

It is a common misconception that margarine is a superior choice to butter because margarine is made from vegetable oil and vegetable oil is lower in cholesterol than animal fat such as butter. This is only half the story. Natural vegetable oil may be lower in cholesterol than butter but margarine is toxic to the body and can cause high cholesterol.

Margarine is a hydrogenated vegetable oil. This means that vegetable oil, which is normally liquid at room temperature, has undergone an artificial process to make it solid at room temperature. Going from liquid to solid may seem like an innocuous change. However, chemists and researchers are increasingly understanding the chemistry of this change and how it creates a false fat that (1) cannot be absorbed by the body and (2) causes internal damage.
