Fatty foods are okay as long as they contain the good kind of fats. An example of these is oleic acid. Oleic acid is a monounsaturated fatty acid found naturally in many plant and animal sources.
As a substitute for animal fats sources that are packed with saturated fat, oleic acid can reduce total cholesterol level, increase the levels of high-density lipoproteins (HDLs) and reduce low-density lipoproteins (LDLs) or "bad cholesterol." Other health benefits of oleic acids include stalling the development of heart disease and boost the production of antioxidants. In the movie Lorenzo’s Oil, oleic acid was used as in ingredient in the ‘oil’ – the medication crated to prevent the start of adrenoleukodystrophy (ALD), a condition which attacks the nyelin sheaths of the body, causing symptoms similar to those in multiple sclerosis. ALD affects only young boys.
Oleic acid not only provides health benefits, it can also help those who on a diet. Oleic acid triggers the body to produce the hormone oleoylethanolamide. This hormone, according to researchers from the University of California, Irvine, can calm hunger pangs.
The best sources of oleic acid include green olives, avocados, canola, grapeseed oil and almonds.
