Wondering why added oils are bad for our bodies? Here’s a round up of the science behind why you should go oil-free in 2020.

About PCRM

The Physicians Committee for Responsible Medicine is a non-profit research and advocacy organization based in Washington, D.C., which promotes a plant-based diet, preventive medicine, and alternatives to animal research, and encourages what it describes as “higher standards of ethics and effectiveness in research.”

Founded in 1985 by Neal Barnard, PCRM says that it “combines the clout and expertise of more than 12,000 physicians with the dedicated actions of 150,000 members across the United States and around the world.”

Here’s the science behind why added oils are bad for our bodies

Impairs endothelial function

According to NutritionFacts.org, “Fatty meals may impair artery function so much that a single high-fat meal can trigger angina chest pain. But whole food sources of fat, such as nuts, appear to be the exception.” Here’s their video about olive oil and artery function:

Oil is packed with calories

Here’s an image from PCRM which demonstrates how empty the stomach looks after consuming 500 calories of oil, meat, or dairy compared to the same amount of calories from fruits and vegetables.

Coconut oil is as bad as animal fat

A review published in the Journal of the American College of Cardiology analyzed the evidence behind recent food trends and myths. PCRM summarizes these findings: “Research also shows that consumption of animal protein and saturated fats (found in meat, eggs, and some oils) increases heart disease risk. Diets focused on green leafy vegetables and plant-based and antioxidant-rich foods, including berries, eggplants, and red cabbage, promote healthful weight and blood pressure levels, reduce inflammation, and lower type 2 diabetes and cardiovascular disease risk factors.”

Increased risk for early death

A study published online in JAMA Internal Medicine found that diets high in saturated fats were linked to early death. PCRM summarizes the findings of this study by stating: “Those who consumed more saturated and trans fats increased their mortality risk from heart disease, cancer, and cognitive diseases when compared to those who consumed more unsaturated fats. These findings support recommendations to limit foods high in saturated fat, including animal products and vegetable oils, in favor of low-fat, plant-based foods.”

Diabetes

According to the PCRM “Since all oils are high in fat (one gram of fat has nine calories), they can be a problem for those trying to lose weight and maintain their overall health. Research also shows oil poses a significant risk to those with diabetes, as it interferes with insulin’s ability to move glucose into the cells.”
