So put down that low fat salad dressing. Go for the full fat kind. Add some REAL butter to those roasted veggies. It's the only way to make sure you get all your nutrients absorbed.
That goes double, triple even, for my WLS buddies. We have enough trouble with malabsorption to risk not getting all we can.
One more bit of advice about all of this -- if you're thinking that you should start eating your salads with full fat salad dressing because of this new research, be sure to double-check the kind of fat that is in your salad dressing. Most of the cheaper salad dressings are made with soybean oil.
It's best to make your own.
Here's a good ranch dressing recipe. Just remember commercial mayo is also loaded with soybean oil. Make your own. There's a good recipe for mayo on this post about coconut oil uses .
