Nuts

There's no doubt that the number of nut butters appearing on grocery shelves is ballooning. But more important than the type of nut butter you choose is what appears on the ingredients list. 

"Choose products that have only one ingredient—your nut of choice—and skip butters that contain excess salt and sugar as well as partially hydrogenated or hydrogenated oils," Andrea says.

"If the product says, 'no stir,' it's likely the manufacturer added rapeseed oil or palm oil for easy spreading. It's those hydrogenated oils that aren't good for us and can increase bad cholesterol levels." 

The bottom line: Eat the butter you like, as long as you choose a natural butter that requires stirring.
