Fats and oils, in particular vegetable oil sources, have been a topic of keen interest over the past 20 years. The role of dietary fats in human nutrition has created widespread interest in fats and oils among consumers, clinicians, researchers, health educators, food producers, and food processors and distributors. Of particular interest have been the health effects of level of intake and type of fats and oils. Much of the current interest stems from the implication of dietary fat in the etiology of chronic diseases such as coronary heart disease (CHD), cancer, diabetes, obesity, and hypertension.

The pressing of nuts and seeds to extract their precious health sustaining oils, dates back thousands of years. The Egyptian civilization...
