We are certainly all aware of the health consequences associated with consumption of ultra processed foods. And this discussion always moves to the role of the sugars and refined carbohydrates in these foods in terms of threatening our metabolic health - and rightfully so.

But there’s another threat associated with these and other foods that is equally important. And that’s the type of oils they contain. In this episode of The Empowering Neurologist, I’m thrilled to welcome Dr. Cate Shanahan, a groundbreaking physician and the author of the eye-opening book Dark Calories. Dr. Shanahan dives deep into a topic that is often overlooked in conversations about nutrition: the dangers of seed oils and their pervasive presence in our diets.

In Dark Calories, Dr. Shanahan reveals how seed oils—despite being marketed as healthy alternatives—can have detrimental effects on our brain and overall health. We explore the science behind these oils, explaining how they can lead to inflammation, oxidative stress, and toxicity, and how these mechanisms threaten our health. By bringing awareness to the hidden dangers of these ubiquitous ingredients, Dr. Shanahan encourages us to reconsider what we think we know about healthy eating.

What makes this episode truly valuable is not just the scientific insights Dr. Shanahan shares but also the wealth of actionable material she provides. Throughout our conversation, we discuss practical steps listeners can take to reduce seed oil consumption and make healthier food choices. From understanding food labels to selecting healthier cooking fats, Dr. Shanahan equips us with the tools we need to nourish our bodies and brains effectively.

She emphasizes the importance of whole, nutrient-dense foods, urging us to prioritize traditional fats over industrial seed oils that can contribute to chronic inflammation and cognitive decline. Whether you’re a health enthusiast or simply looking to improve your diet, this episode is packed with invaluable tips, like what to order when you go out to eat, that you can implement immediately.
