Neccssary Nutrients and Disease Fighters in Oils

1) High-quality vegetable oils are the best way to meet your body's daily requirement for fat and fulfill many of the body's nutritional requirements.

Though excess consumption of saturated fat, and the cholesterol found in animal fats, has been associated with heart and arterial disease, some fat is necessary in a daily diet to ensure good health. Current studies suggest that an ideal diet might provide 25 percent of calories from oils and fat.

Fat is needed by the body for absorption of the fat-soluble vitamins A, D and E. Vegetable oils arc one of the few sources of the essential fatty acids (EFA), linoleic and linolenic acid. Vegetable oils, especially wheat germ oil, arc good sources of vitamin E.

Some oils also contain omega-3 fatty acids that have been shown to protect the body from heart disease and some types of cancer. Flax seed, canola, walnut, and soy oils are good sources of omega-3 fatty acids.

Monounsaturated oils, like olive, peanut, canola, and high-oleic oils also protect the body from heart disease by raising the blood level of HDL, the good cholesterol. Higher levels of HDL prevent plague build-up on arterial walls. Consumption of polyunsaturated oils, like sunflower and soybean oils, lowers levels of the bad cholesterol, LDL, but also of the good, HDL.

2) Oil can be extracted from many raw materials and has many uses but, for small-scale processing, edible oils for domestic cooking are the most important. Oils are also an important ingredient for making soap. The residue of the raw material, after the oil has been extracted, may have a value even higher than the oil itself - for making groundnut cookies for example or other baked products. The by-product of the oil extraction process, known as oil-cake, is also used as animal feed or if there is a substantial surplus, as fertilizer in home gardens. The major edible oils and their uses are:
