There are a lot of misconceptions when it comes to cooking oils-and we mean a lot! Separate fact from fiction when it comes to the heated debate over fats.

I've spent a large portion of my career fighting the wrongful demonization of dietary fat, trying to set the record straight, and to reclaim respectability for fat in general, saturated fat in particular, and-most importantly-cholesterol. Now it's time to take on the whole area of cooking oils.

The subjects of dietary fat and cooking oils overlap-but they're not the same thing. While all cooking oils are made from fat, they have specific properties of their own-how they stand up to heat, for openers. And there's a lot of misinformation about the best way to use cooking oils to get maximum benefits from them.
And there are a lot of myths. Two of the most common: Extra virgin olive oil is the best stuff ever ... you should use it for everything! Coconut oil is a fantastic cooking oil-its saturated fat stands up to high heat beautifully!

Well, if you're an informed health consumer, you've probably heard those statements, and you may even agree with them. I don't blame you. Those ideas are deeply embedded in what's now called "the health space," meaning places where people talk about, read about, tweet about, discuss, and debate what's healthy and what's not.

The problem is that they're not true. Or at least they're not completely true. Because with cooking oils, the devil is truly in the details. And you simply can't have a serious discussion about healthy cooking oils without including one absolutely critical detail that no one seems to ever talk about-temperature.

Take extra virgin olive oil, for example, everybody's poster child for the best oil ever. Extra virgin olive oil is made by simply crushing olives and extracting the juice. It's made without a hint of chemicals or industrial refinement, and under temperature that won't degrade the oil (i.e., less than 86°F). People pay a lot more money for extra virgin olive oil, and then proceed to use it for all their cooking needs.

Big mistake. Think about it. Why did you pay such a high premium for extra virgin in the first place? It was to get all those spectacularly healthy olive polyphenols, in virgin condition, undamaged by heat or chemicals. So why in the world would you pay a lot of money for a delicate, carefully prepared oil that's dripping with delicate compounds, and then heat it to a high temperature, which is basically guaranteed to destroy most of the wholesome compounds that you paid for? Doesn't make much sense, does it?

Cooks and chefs have a term for the temperature at which oils begin to be damaged-it's called a smoke point. If an oil is heated until it smokes, the valuable nutrients will be damaged. Worse, the oil itself becomes harmful to ingest. If you take a healthy fat-such as extra virgin olive oil or unrefined coconut oil-and cook it past its appropriate temperature tolerance, you've just taken a smart fat and made it into a dumb one.

So pay attention to the temperature guide at right, and never use an oil at a temperature that causes it to smoke. (If you happen to accidentally burn an oil from time to time, just take the pan off the heat, wipe the pan with a paper towel, and start over.)

I suggest you choose 1-2 oils you can use for high-heat cooking-such as avocado, pecan, extra-light olive oil, or ghee-and let these be your staples for high-heat cooking. Medium-high-heat oils are the ones you'll probably cook with most of the time. They're great for browning meat or poultry, or for cooking vegetables. Good choices include virgin olive oil (not extra virgin), almond oil, hazelnut oil, and macadamia nut oil.

You should probably also choose 1-2 medium-heat oils-such as nutrient-rich, unrefined coconut oil and sesame seed oil-for when you don't heat a pan past medium heat.

More nutrient-rich oils, such as extra virgin olive oil, are wonderful for drizzling on foods or for salad dressings. High-lignan flaxseed oil can be used for drizzling or for salad dressings (but never for cooking). Other oils that work well for this purpose-oils that can be used for dressings or sprinkled on dishes for extra flavor after they have been cooked-include sesame, pistachio, and walnut oils.

The bottom line: Use the right oil, and use it at the right temperature! That's just smart cooking.
