Why all calories are not created equal?

In a recent study from the journal: Advanced Nutrition, https://www.sciencedirect.com/science/article/pii/S2161831323002752?via%3Dihub, the degree of processing of a specific food can increase available energy, hence, more calories are available for absorption than initially thought from foods that are more processed.

For example raw nuts are the least absorbed, then roasted, then chopped and lastly nutbutters, which have the most absorbable calories.

Eating raw and roasted nuts, if trying to lose weight, have less absorbable calories than nut butters, for example.  If in a weight loss program, choose more raw or roasted, and limit or skip the nut butters.

The tinier the surface area, the greater the absorption.  Whole nuts = larger surface area = less absorption.  Nut butters = smaller surface area = more absorption.

Also, by eating whole unprocessed foods, we provide some fuel for the good bacteria in our large intestine.

Take home?  Choose whole, unprocessed foods, including nuts/seeds, if striving to lose weight!

Have a healthy day!
