The downsides of frozen yogurt is that it's high in added sugar, which is often a result of added corn syrup and sweeteners, which potentially less probiotics than regular yogurt contains.
Frozen yogurt might even cause digestive issues for some people due to the lactose and additives and hidden calories from the toppings, which make it more of a treat than a health food if it's not carefully chosen.
Frozen yogurt also often contains artificial ingredients and stabilizers like carrageenan, and it can also have a high glycemic impact.
Many brands of frozen yogurt contain significant added sugar, which counteracts the tartness, which is also often disguised with other names like maltodextrin or corn syrup, which contributes to excess sugar intake.
The freezing process for frozen yogurt also can kill or even inactivate the beneficial live cultures in yogurt, which reduces the probiotic benefits when compared to non frozen yogurts.
Frozen yogurts often also contain chemical additives, artificial sweeteners, like sucralose and thickeners like carrageenan, which can cause inflammation or gut issues.
And also with toppings as well as portion sizes and added sweeteners, the frozen yogurt can also become a high calorie, high carb dessert, which is also similar to that of ice cream.
For people that are lactose intolerance, the dairy content in the frozen yogurt may also cause gas, bloating and pain, especially if the live cultures are not active.
And some artificial sweeteners used in frozen yogurt like carrageenan and maltodextrin, can also negatively affect gut bacteria and cause digestive distress.
And the high sugar and certain sweeteners in frozen yogurt like maltodextrin can also cause rapid blood sugar spikes, which can be problematic for people that are diabetic.
Frozen yogurt is healthy although too much could be bad.
Fresh non frozen yogurt is even healthier due to the good live cultures in the yogurt that are good for gut health.
