Too much oil is bad for one. The reason natural oils are good for us is that in nature, oils are found in whole vegan foods accompanied by fibre. Fibre provides a natural mechanism for slowing down the intake of oils so that we are not likely to get too much at once. We feel full quickly and stop eating the oil-containing food. On the other hand, refined oils come with no fibre; so it’s easy to consume too much. This excess oil is stored as fat in the body. For example, nuts, seeds and coconuts contain natural oils, but when one consumes these as whole foods, one also consumes fibre. You would have to eat a lot of nuts, for example, to get the equivalent of one tablespoon of oil, but only a few French fries to get the same amount. Excess fats contribute to diabetes, hypertension, obesity, and heart disease.
