Nutritionists Laura Parada and María Casas Rank Dietary Fats From Butter to Olive Oil

Vogue recently shared a guide by nutritionist Laura Parada, author of *What Drives Us to Eat This Way*, and dietitian María Casas, who organized various fat sources using a traffic-light system. In the red zone, you'll find things like processed snacks, baked goods, fried foods, and meats such as bacon and sausages. Trans fats, often in certain margarines, are particularly worrisome for heart health, though their use is increasingly regulated. The orange category includes butter and coconut oil because of their saturated fats. Yellow items, like eggs and some cheeses, have mixed effects. The green category features healthy options such as extra-virgin olive oil, nuts, and fatty fish. Parada stresses that it's not just about individual foods, but how you consume them overall.
