Not So Healthy Vegetable Oils

First of all, I can’t help but admire the advertising prowess of vegetable oil companies. It takes a lot, to sell poison as the good stuff. When I was very little and my mom switched from the local groundnut oil to vegetable oil because we are trying to live healthily and then the message was (and still is) how healthy vegetable oils are.

When I became much older I started questioning vegetable oil because when I squeeze vegetables like carrots or ugu (pumpkin leaves) I won’t find oil. Unlike coconut, when eating it you will know it has oil or when peeling orange you will see traces of oil.

However, I felt there must be a way they extract the vegetable oil from the vegetable. My interest in vegetable oil resurfaced when I decided to start making healthy food choices. I became curious about the extraction process. If they were really extracting anything and if they were, how safe for the body.

After attending NITC 14, where we talked industry-funded research and our dear vegetable oil. Vegetable oils cannot be extracted just by pressing or separating naturally. They must be chemically removed, deodorized, hydrogenated and altered. These are some of the most chemically altered foods in our diets, yet they get promoted as healthy and people fall for the “vegetable” part in the name. Then you begin to wonder how exactly it is healthy when heart disease and cancer continue to rise at an alarming rate despite avoiding the “bad fat”.

Most of these “heart healthy vegetable oils” are non-traditional and factory-made oils that started coming up at the beginning of the nineteenth century when the world was basically in love with industrialization. The dangers of these oils are as follows

  • They contain very high levels of polyunsaturated fats. Polyunsaturated fats are highly unstable. They oxidize easily. These oxidized fats cause inflammation and mutation in cells.
  • They are loaded with massive amounts of trans fats. Trans fats are unsaturated fats that are toxic and associated with an increased risk of various diseases, like heart disease, cancer, diabetes and obesity. They are so bad that even the governments around the world have started taking action, setting laws that command food manufacturers to reduce the trans fat content of their food
  • Many vegetable oils contain BHA and BHT (Butylated Hydroxyanisole and Butylated Hydroxytoluene). These artificial antioxidants keep the food from spoiling too quickly, but they have also been shown to produce potential cancer compounds in the body. And they have been linked to things like immune system issues, infertility, behavioural problems, and liver and kidney damage.
  • Vegetable oil contains very large amounts of biologically active fats called Omega-6 which are harmful in excess as it creates unbalanced levels that lead to health problems.

Which oils to use then?

The best oils to use are natural unprocessed oils used that our great-grandparents used for cooking. Some are as follows

  • Palm oil
  • Groundnut oil
  • Coconut oil
  • Palm kernel oil
  • Shea butter (although it is not common in Nigeria, some parts of West Africa use it to cook)
  • Natural butter
  • Olive oil

Note that palm oil and coconut contain saturated fat, so use in moderation.
