Calorías Oscuras: Cómo los aceites vegetales destruyen nuestra salud y cómo podemos recuperarla

What are vegetable oils and why are they harmful?

Vegetable oils, such as soybean, corn, sunflower, and canola oils, are found in most processed foods. Although they were promoted as healthy, modern science suggests that their high content of omega-6 polyunsaturated fatty acids and the toxic compounds generated during their refining can promote chronic inflammation. Dr. Catherine Shanahan explains how these oils, which she calls 'dark calories,' interfere with mitochondrial function and contribute to oxidative stress, a key factor in diseases such as type 2 diabetes.

The connection between vegetable oils and type 2 diabetes

Type 2 diabetes is characterized by insulin resistance and metabolic dysfunction. Emerging research indicates that excessive consumption of processed vegetable oils can exacerbate these problems. By altering the composition of cell membranes and promoting systemic inflammation, these oils can hinder the body's ability to regulate glucose. The book 'Dark Calories' delves into these mechanisms, offering a perspective that goes beyond conventional dietary recommendations.

What makes 'Dark Calories' unique?

Unlike other nutrition books, 'Dark Calories' combines rigorous biochemical research with an accessible narrative. The author not only identifies the problem but also provides a practical plan to eliminate these oils from the diet and replace them with healthy fats. Readers especially value her ability to translate complex concepts into actionable advice. As a prominent review notes, Dr. Shanahan addresses questions that many health professionals avoid, offering evidence-based answers.
