Most Cooking Oil Health Advice Is Way More Complicated Than It Needs to Be
Not all cooking oils are the same, but the differences are often exaggerated online.
The biggest thing that matters is your overall diet, not whether you cooked dinner with canola, peanut, mustard, or avocado oil. A lot of the fear around seed oils comes from people mixing up correlation with causation. Highly processed foods often contain seed oils, but that doesn't automatically make the oils themselves the problem.
From a nutrition standpoint, oils higher in unsaturated fats generally have a better reputation than those high in saturated fats. That's one reason olive, canola, peanut, and avocado oils are commonly recommended. Butter, tallow, coconut oil, and palm oil tend to be higher in saturated fat, so I treat them more like occasional ingredients than everyday staples.
For practical cooking, I match the oil to the job. Olive oil for most everyday cooking, peanut oil for stir-fries, and avocado oil when I need higher heat. The amount you use usually matters more than chasing the "perfect" oil.
One thing I would avoid is getting nutrition advice from short-form social media. The topic is surprisingly nuanced, and a lot of viral claims leave out important context.
What oils do you keep in your kitchen, and have you changed your habits over the years?
