For decades we have been told to avoid fat, that fat makes us fat. This is not true. Fat is one of the three essential macronutrients necessary for powering our bodies. The key is choosing the right fats for the right usage and avoiding harmful fats. The harmful fats to avoid are those oils found in plastic containers at the grocery store- namely canola oil, corn oil, vegetable oil, soybean oil, sunflower oil, safflower oil, as well as margarine and buttery spreads. These oils are highly processed and are already damaged (oxidized) by heat and solvents used in the processing before they are put in the container, rendering them rancid and stripped of nutrients. Then they are deodorized to mask the rancid smell. They are then packaged in transparent, plastic containers which allow them to be further oxidized via light and heat. These hydrogenated or partially hydrogenated industrial seed oils are also found in most processed foods, fast foods, and often in restaurant food.
Once you throw these out, what do you use? If you are cooking, use fats that are solid at room temperature, which means they don’t degrade the same way under heat. These fats include coconut oil, butter, ghee, lard (pork fat), tallow (beef fat), duck fat, chicken fat, or lamb fat (for animal fats, look for pastured, well-raised animals). Use unsaturated oils for non-heated purposes, like dressings. These include cold-pressed and extra virgin olive oil, avocado oil, sesame oil, macadamia nut oil, and walnut oil.
