Why avoid seed oils?

Why avoid seed oils? How?

Overview

Many seed oils are vegetable oils that are processed and heat-treated. The processing denatures them and renders them inflammatory for many people and their digestion. Some vegetable oils, such as olive oil, are not treated, but are adulterated in the market.

Saturated fats, such as coconut oil, and animal fats, such as butter, have been blamed in error for many years. The real distinction is between highly processed vegetable oils, such as cottonseed, canola, corn, or soybean oil, which tend to be unhealthy for many people, and natural oils and fats, such as coconut oil, butter, olive oil, or flaxseed oil, which tend to healthy for many people.

Vegetable oils are widely consumed, because they are cheap, not because they are healthy.

What are seed oils? Where are they found? How are they produced?

Seed oils are vegetable oils obtained from the seeds of plants, usually extracted under heavy pressure and processed with heat and other treatments. Seed oils include cottonseed oil, canola oil, corn oil, sunflower oil, peanut oil, soybean oil, and sesame seed oil. These oils are found in supermarkets. They are used by most restaurants for frying, for example for frying potatoes.

As Dr. Jason Fung MD points out, the production and consumption of cottonseed oil began with the waste product of cotton, which was harvested for fiber and fabrics to make clothes. For every hundred kilos of fiber, there are one hundred and sixty-two kilos of cotton seeds that are largely useless. In 1911, these seeds were processed and marketed as “Crisco”, which was promoted in free recipe books as a “healthy alternative” to lard.

Seventh Day Adventists and other gung-ho vegans promoted abstinence from eating animals, and Crisco took off. In 1955, President Dwight Eisenhower had a high-profile heart attack, which was attributed to eating too much fat by Ancel Keys, a prominent academic. Without proof of cause and effect, animal fat and cholesterol were eagerly blamed for gaining weight and susceptibility to heart attacks. There was little or no distinction between healthy, natural fats and processed fats in the form of hydrogenated, processed vegetable oils. Lately, there has been a public awareness that these processed vegetable oils contain “trans fats”. They have been modified chemically to try to keep them stable on store shelves, but the processing denatures them, rendering them inflammatory to many a digestive system.

By the 1950s, cottonseed oil itself was becoming expensive, and Crisco once again turned to a cheaper alternative, soybean oil. The Center for Science in the Public Interest (CSPI) declared the switch from lard and other saturated fats to trans-fat laden, partially hydrogenated oils to be “a great boon to Americans’ arteries”. Soybean oil is now the most heavily consumed vegetable oil in the USA. “Do not eat butter”, they said. Instead, replace it with the partially hydrogenated vegetable oil (read: trans-fats) known as margarine. That edible tub of plastic was much healthier than the butter that humans had been consuming for at least three thousand years, they said. 

Industrial seed oils, such as cottonseed are high in the omega-six fat linoleic acid, which is found in eggs, nuts, and seeds, but Crisco introduced an isolated and adulterated type of linoleic acid. These omega-six seed oils can now be found in nearly all processed foods and in grocery aisles in plastic bottles for cooking. These oils are highly susceptible to heat, light, and air, and are exposed to all three during their processing. They can inflame many a digestive system.

The truth is inside you. “Look for the truth, and your health will follow,” as Dr. Herbert Shelton, MD, said.

Fat does not make you fat.

Contrary to the popular belief, healthy fats do not make you fat. It is sugar and refined grains, such as wheat flour, that make you fat. If you cut the sugar and the refined grains, substituting stevia and either certain vegetables or even meat, then you can lose the fat. 

Why avoid seed oils?

They are removed from their natural state. They are heat-treated and processed in a way that denatures them and renders them unhealthy for many people. They contain mostly fats known as omega-six fatty acids, which inflame the digestion of many people.

What are healthy oils and fats?

Healthy oils and fats are not processed, not heat-treated, not bleached, and not deodorized. They include coconut oil (for frying and to resist high heat), olive oil, flax seed oil, and hemp seed oil, among others.  Coconut oil has other healthy uses than for high-heat cooking.

You can make a natural adhesive remover from coconut oil, baking soda, and essential oil of orange.

What if you do not digest any oils well?

The digestive enzyme known as alkaline phosphatase is required to break down oils, fats, nuts, and seeds. According to Dr. Peter D’Adamo, people with blood types A and AB tend to excrete less of this enzyme than those with blood types O and AB. 

This means that if you have blood type A or AB, you may be less able to digest oils, fats, nuts, and seeds. A few peanuts may be healthiest for your digestion. If you have blood type O or B, then you may be able to digest a handful or more of nuts at a time, at the end of a meal or between meals as a snack.

According to blood type eating, flax seeds, pumpkin seeds, and walnuts are healthy for both blood types O and A.
