A cautionary, fascinating tale of how so-called 'heart-healthy' seed oils can make us sick

On this episode of The Big Middle, the compelling case against seed and vegetable oils still being touted as ‘heart-healthy’. Those bottles of chemically-extracted fat that take up entire aisles of grocery stores are increasingly seen as hazardous to our health – key drivers of autoimmunity, macular degeneration and the modern plague of lifestyle diseases known as metabolic syndrome.

Even the major makers of soybean, sunflower, corn and other seed and vegetable oils are quietly backing away from them, well aware of the biological damage they can do.

Tucker Goodrich has been sounding the alarm over the health risks of seed oils for more than a decade. He suffered 20 years of gastrointestinal torment and much – scary – more that mystified his doctors. So he dug into the medical science himself, eventually pinpointing industrial seed oils as a villain in his sickness puzzle.

Tucker’s become a recognised world authority on the subject and I guarantee his Patient Heal Thyself story will blow your mind.



“The problem with seed oils is they ultimately break down to some highly toxic substances [oxidative stress process] – both when you’re cooking with them – and in the body.”

On debunking of key studies promoting the ‘heart healthy’ aspect of seed oils: “Is there another explanation for why we get heart disease other than this pathway that starts with seed oils and leads to oxidation of  Omega 6 fats and consequent damage? There isn’t. This is the predominant hypothesis in cardiovascular disease for why this is happening. But they don’t say it. They just say take this statin and you’ll have less LDL [cholesterol].”

On how ditching gluten and seed oils, decades after he quit sugar to prevent more cavities, caused him to “forget” to eat carbs: “All my extra weight just fell off…my pants fell to the floor…What happened when I stopped eating seed oils is that I lost my desire to eat carbohydrates. I forgot to eat carbs for a week…Subsequently, I discovered I can bring back the stroke-like symptoms if I eat whole wheat.”

On how he’d been prone to breaking bones doing “stupid things” mountain biking and skiing, but broke none after ditching seed oils and gluten: “I’m like a rubber ball now…My healing capacity is up enormously…slipped and fell down the stairs of my ski condo.. later, I noticed a huge bruise ..but I just never felt it. It got weird enough that I was starting to look into whether I had leprosy. One of the symptoms of leprosy is that you can’t feel your periphery.”

“It turns out there’s literature on this. These metabolic products of seed oils break down into things that can induce pain. There’s actually a fellow by the name of Christopher Ramsden who did a study into reducing the use of seed oils to reduce headaches.” 

On taking over-the-counter Omega 3, 6, 9 supplements: “It’s roughly equivalent to giving a drowning man a glass of water. We eat too much Omega 6 fats. Nobody needs to have more. Just as with age-related macular degeneration, cutting Omega 6 fats will make it easier for your body to access the more beneficial Omega 3 fats.”
