Healthiest Cooking Oils To Use: Why Vegetable Oil Is Bad For Your Health?

Whether you’re sauteing onions or dressing a salad, there are lots of cooking oil options out there. But, it’s important to note that not all oils are made the same. Some oils, such as certain vegetable oils, are highly processed and may actually wreak havoc on your health. Read below to learn why certain vegetable oils are terrible for your health and which alternatives you can use instead.

Vegetable Oils: Not All The Same

Vegetable oil refers to any oil that is derived from a vegetable. Canola and olive oil are both technically vegetable oils. The difference, however, lies in how these two oils are made.

Extra virgin olive oil is extracted through the natural process of cold-pressing. It’s as simple as it sounds. Olives are pressed under high pressure without the use of heat to extract their oil. That’s it. End of process.1,2

Cold-pressed oils like extra virgin olive oil don’t receive any sort of chemical treatment that may modify the vitamins and nutrients in the oil. This natural process keeps all the healthy fats and nutrients intact for your body and benefit.3,4

Unhealthy Oil Options

The vegetables and ingredients undergo chemical procedures such as bleaching, deodorizing, and degumming. Through these chemical processes, many of the nutrients are stripped away. The basic rule is this: the more processing an oil has undergone, the fewer nutrients it has.5

For many years, canola oil was used as an industrial lubricant. Scientists and plant breeders had to modify the rapeseed used to make the oil to reduce the erucic acid, a non-essential fatty acid, to a point below 5% before it became a common food oil.6 Additionally, almost 90% of the crops used for canola oil are now genetically modified.7 This speaks to how much chemistry and science play a role in making these oils.

Why Is Vegetable Oil Bad For You?

Refining vegetable oil actually changes the molecular make-up of the natural fats in the oil. A process known as hydroginization transforms normal saturated fats into trans fatty acids. Your body doesn’t even recognize these kinds of saturated fats and can’t absorb them correctly. The FDA determined that these types of saturated fats are not a safe food. That’s largely because trans fats from hydrogenated oil may increase bad cholesterol and lower good cholesterol.8

What To Look For In An Oil: Good Fats Vs Bad Fats

Not all fat is bad for you. Recent studies suggest what matters more is the type of fats you eat, rather than how high or low the fat content is. Unsaturated fats, like polyunsaturated fats, are actually good for you and may support heart health.9

This scientific process actually turns unsaturated fats into trans fats. These fats occur rarely in nature and are supposedly responsible for increasing bad cholesterol (LDL) which can damage arteries and lead to heart-related issues.10

That’s why you want an oil that contains polyunsaturated fats or monounsaturated fats, instead of trans fats. These fats contain healthy linoleic and oleic acid which can support healthy cholesterol levels and heart health. Oils that are high in polyunsaturated fats and monounsaturated fats include extra virgin olive oil, avocado oil, and coconut oil.11,12

Note: Lots of processed foods have canola oil and other hydrogenated vegetable oils in them. The oils and shortenings present in processed foods like cookies, crackers, and cakes contribute a large percentage of trans fats in many diets.13

MCT oil | Nucific

If weight loss is your goal, then adding MCT oil into your diet might be a good idea. The name stands for “medium-chain triacylglycerols”, which means that the chains of fatty acids in this oil are shorter than the long-chains found in most oils. As such, the body absorbs and burns these fats differently.23

It’s believed that these shorter chain fatty acids can help reduce appetite which may keep weight gain under control.24 And, MCT oils are shown to provide more fat-burning energy than other oils.25
