Have you heard the news? Fat isn’t bad for you! We’ve known that all along, of course—our great-grandparents ate butter and lard, not low-fat margarine and zero-calorie mayo—but now even mainstream health experts are saying that a low-fat/no-fat diet is not a good idea. Mary Flynn, a professor of medicine at Brown University, recently told an NPR reporter this: “There have been a number of studies done, and there’s been no benefit for low-fat diets to lead to better weight loss, and there’s no benefit for low-fat diets to lead to less disease.” She added that avoiding fat is not the key to a healthy diet. Common sense is finally becoming more common! For the full story, click here: http://www.npr.org/blogs/thesalt/2014/03/28/295332576/why-we-got-fatter-during-the-fat-free-food-boom.
That said, remember that there’s a big difference between refined, rancid fats and fresh, unprocessed fats—you still want to avoid rancid fats. That means opting for unrefined oils (extra-virgin olive oil, not vegetable oil) and products from grass-fed animals whenever possible (grass-fed beef, not 99-cent-per-pound ground chuck). Here’s a quick rundown of what to look for and what to avoid when it comes to fats. Print out these lists and take them to the store with you!
GOOD FATS
- Unrefined oils (look for the words “extra-virgin,” “cold-pressed,” and “unrefined” on the label)
- Whole-milk dairy products (cheese, milk, butter, yogurt, etc.) from grass-fed animals whenever possible
- Free-range eggs (also called pastured eggs)
- Grass-fed or wild meats (including deli meats and cured meats like bacon and sausage but without the nitrates/nitrates)
- Wild and/or sustainably farmed seafood
BAD AND UGLY FATS
- Anything containing trans fat (look for the words “hydrogenated,” “partially hydrogenated,” and “interesterified” on the label)
- Refined oils (these include corn, soy, grapeseed, canola, vegetable, and cottonseed oils; peanut oil is also often refined)
- Olive oil that is not labeled extra-virgin
- Reduced-fat dairy products
- Conventional eggs
- Conventional meats
- Factory-farmed seafood

Sheryl,
In your statement above, good fat extra virgin olive oil, then below it you say extra-virgin is bad. Not sure what you mean.
In the bad section it is olive oil if it is not labeled as extra-virgin. In that case you should avoid it.
What is your opinion on avocado oil?
I think its great if its cold pressed or expeller pressed and used for salads, dips or spreads. For cooking I suggest butter, ghee or coconut oil!
