According to " How Products Are Made" , there are two types of ingredients that go into making marshmallows, and they are emulsifying agents and sweeteners.
This high fat food stimulates the gallbladder to squeeze out some bile into the small intestine, that bile emulsifies the fat, or basically mixes the fat up, and makes it easier to absorb.
This new set of rules framed unhealthy food less in terms of the nutrients it contains (fats, carbohydrates etc) and more by the degree to which it is processed (preserved, emulsified, sweetened etc).
This little gem, is a recent addition, it's called MUTHA, you can see I used it up, it goes fast, and so it's Shea butter based, and, you just kinda emulsify it.
That bile emulsifies the fat, essentially making fat organize into small " micelles" , which are tiny bubbles of mixed lipids and bile acids, rather than clumping together, and making them easier to absorb.
