We are used to hearing that fat is bad for us and we should reduce it as much as possible. What perhaps few people know is that there are two types of fat: good fats and bad fats.
Bad fats, or saturated fats, are found for example in sausages, lard, butter, fried foods, fatty meats, drinks and industrial fruit juices. They are difficult to metabolise and therefore tend to accumulate in the blood, causing an increase in total cholesterol and LDL (bad) cholesterol.
Good fats, or unsaturated fats, on the other hand, are essential for maintaining good health and general well-being. They are mainly found in plant-based products such as olives, olive oil and nuts, as well as in oily fish, salmon and mackerel.
Like proteins and carbohydrates, they act as fuel for the body's vital activities. They are the nutrient with the highest caloric and energy density, providing 9 calories per gram. They are key players in various processes such as the transport of fat-soluble vitamins (A, D, E and K), structural support of the body and involvement in the body's biological processes such as muscular growth and development.
