Sorry, But I Told You Vegetable Oils Are Bad

This week’s edition of the British Medical Journal (April 12, 2016) published an article explaining how vegetable oils (unsaturated fats) lower blood cholesterol levels when they replace animal fats (saturated fats), however, based on extensive research and a reanalysis of an older study, they do not reduce the risk of heart disease, and this substitution also increases the risk of sickness and death.

So called “good fats,” the isolated vegetable oils (canola, corn, flaxseed, olive, safflower, etc.), are at best medications, and at worst serious toxins. They make you gain weight; “the fat you eat is the fat you wear.” Various forms promote cancer, gallbladder disease, suppress the immune system, and/or cause bleeding. This current report finds corn oil, sunflower oil, safflower oil, cottonseed oil, and soybean oils damage the arteries and increase the risk of death from heart disease and of overall death.

The authors of the research paper and the editorial seem perplexed about these findings and do not know what to recommend. According to these publications replacing some of the butter with corn oil actually makes sick people even sicker. This leads some experts to argue that this research shows saturated fat is not harmful: a wrong conclusion. Saturated fat is synonymous with animal foods (meat, poultry, eggs, and dairy) and these foods are well recognized as “disease producers.” Vegetable oils make a bad diet worse. Physicians, scientists, and consumers now think, “There is nothing left to eat.” But, that’s not so.

To make sense of this apparent dilemma and to understand what is proper for humans to eat is to recognize the human diet is based on starches (beans, corn, potatoes, rice, etc.). These carbohydrate-filled foods have nourished all large populations of people throughout all of verifiable human history. Filling in this common knowledge settles all of the confusion – and provides a healthful diet, while at the same time minimizing the intake of animal foods, and equally toxic, vegetable oils.
