The term grease it has several uses. For biochemistry, fats are organic substances that are formed when fatty acids combine with glycerin. Fatty acids, in turn, are elements that combine with bases to form salts and that, when in solution, increase the concentration of hydrogen ions.
Fats are present in numerous fabrics of plants and animals. The most frequent are triglycerides, which are made up of three fatty acids bound to a glycerin molecule. It is important to mention that fats are part of the diet of humans and most animals.
It is possible to differentiate between unsaturated fats (made up of unsaturated fatty acids), present in olive oil and olive oil sunflower, for instance; and the Saturated fats (formed from saturated fatty acids), which are found in peanut or peanut butter and bacon or bacon.

On the other hand, it is very important to understand the difference between accumulating fat in the body and consuming it: a diet in which they do not exceed 30 percent of the components is ideal to take advantage of these nutrients and avoid their storage.
Among the most suitable fats for our body is the olive oil, which belongs to the monounsaturated group and is a food that is as delicious as it is healthy. Although it is more expensive than other types of oil, we should not use much per plate. Extra virgin and raw olive oil is especially recommended.
