The un-ultra-processed version of Twinkies are also going to contribute to obesity and heart disease. Sponge cake and cream is high in empty calories, very high in saturated fat, and all around bad for you.

I think people sort of miss the forest for the trees with this stuff. Making your own milkshakes, or ice cream, or fried chicken, or Twinkies, will not save you from obesity.

It's not the processing per-se. All these foods are ultra-palatable, readily available, and high in calories/saturated fat.
