It all started in the 1950s, when a cooking oil company advertised how their cooking oils make fried foods lighter and are better than the traditional butter. This got people talking and if you look at the cooking oil preferences people have today, it is all about vegetable oils.

ARE VEGETABLE OILS AS HEALTHY AS THEY ARE DEEMED TO BE? Studies have established that these "heart-healthy" oils, such as sunflower, canola and cottonseed, are in fact the leading causes of chronic illnesses in America. To make matters ironic, they even cause heart disease, besides various types of cancers.

COTTONSEED OIL WAS ORIGINALLY A WASTE: The critically acclaimed book, The Happiness Diet, mentioned how the leading cooking oil global producer duped its consumers. First of all, they sold their commercially produced oils as better replacements for animal fat, which they clearly are not. Secondly, their oil production generated waste in the form of cottonseed oil. The book mentions how that waste product was sold off as a 'nutritious' oil option, despite it having no nutritional value at all!

EVEN VEGETABLE OILS WERE "NOXIOUS WASTE": An article published in the Science Monthly mentioned how not just cottonseed oil but also vegetable oils at large were noxious waste at first. It is only marketing that made these turn into “healthy” oils.

VEGETABLE OILS OFTEN TURN INTO TRANS FATS: In order to get a desirable consistency, often these vegetable oils undergo hydrogenation. This leads to formation of trans fats. Trans fats are really unhealthy and contribute to disorders such as that of the liver, diabetes, obesity, gastrointestinal disease and even cancer.

THEY CAUSE CANCERS OF BREAST, COLON AND OTHERS: Trans fats have been seen to double a women's risk of breast cancer, and increase the risk of colon and many other types of cancers as well.

THESE OILS ARE OFTEN RANCID: The process of extraction of these oils leads to their oxidation and hence, makes them rancid. This leads them to become toxic and inflammation-inducing.

WHAT TO USE INSTEAD? The best would be retorting back to the usage of animal fats, such as butter and lard. Prefer butter that is grass-fed and lard that is pastured without hormones. If you don’t want to use animal fats and want to go for a plant-based option, the best choices would be coconut and palm oil.
