What about frozen yogurt or can I freeze my store-bought yogurt?
No on the first part of the question and yes on the second!
Frozen yogurt purchased at local stores or at frozen yogurt shops generally are very high in added sugars. Added sugars are part of what we are told to eliminate.
Now, freezing your store-bought yogurt? That you definitely can do!
While freezing it destroys some of the probiotics, those probiotics continue growing once you eat them and they warm back up in your intestines and digestive tract.
So go ahead -- treat yourself to a frozen yogurt, but make it one you freeze at home yourself!
