STORY AT-A-GLANCE

  • Replacing dangerous vegetable oils such as corn oil, soybean oil and canola oil with healthy fats such as lard, butter or coconut oil is a simple way to boost your health and reduce your risk of chronic disease, including cancer
  • Vegetable oils are a concentrated source of omega-6 linoleic acid, which has led to a severe imbalance between the omega-6 to omega-3 ratio in most people’s diets. This imbalance appears to be why vegetable oils promote cancer
  • Consumption of saturated animal fats such as butter, lard and beef tallow fell by 27% between 1970 and 2014, while consumption of vegetable oils rose by 87%
  • Historically, mankind consumed omega-3 and omega-6 at a ratio of 1-to-1. Today, most get 25 times more omega-6 than omega-3, and this imbalance has been linked to heart disease, gastrointestinal diseases, inflammatory conditions and cancer, especially neuroblastoma, breast, prostate, colon and lung cancer
  • Your body metabolizes omega-3 and omega-6 PUFAs into eicosanoids (hormone-like substances), and as a general rule, omega-3 eicosanoids are anti-inflammatory while omega-6 eicosanoids have proinflammatory effects. Part of the benefits of omega-3 fats is that they block the proinflammatory effects of omega-6 eicosanoids

 

Dietary fats are a crucial component of a healthy diet, but the devil’s in the details, and the type of fats you choose can make a world of difference. Replacing dangerous oils with healthy fats is one simple way to boost your health and reduce your risk of chronic disease.

Sadly, the fats that promote ill health are the very ones we’ve been told are the healthiest, and vice versa. Among the absolute worst types of fat you can eat are vegetable oils, such as corn oil, soybean oil, sunflower and canola oil, found in most processed foods and restaurant meals.
