Ingredients to watch

Watch out

Milk Chocolate

A combination of sugar, cocoa butter, chocolate, nonfat milk, milk fat, lactose, soy lecithin, and PGPR. It provides the signature creamy exterior shell and adds significant sugar and saturated fat content.

Good

Peanuts

Roasted peanuts ground into a paste to create the filling. They provide protein and healthy fats, though they are often processed with added salt and sugar in this product.

Watch out

Sugar

Used as the primary sweetener in both the chocolate shell and the peanut butter filling. High intake of added sugars is linked to metabolic health issues and energy crashes.

Watch out

Dextrose

A simple sugar used to sweeten the peanut butter center. It is absorbed very quickly into the bloodstream, leading to rapid spikes in blood glucose.

Neutral

Salt

Added to balance the sweetness of the sugar and enhance the flavor profile of the peanuts. Excess sodium intake can contribute to high blood pressure in sensitive individuals.

Neutral

TBHQ and Citric Acid

Preservatives used to maintain freshness and prevent the fats in the peanuts from going rancid. These are synthetic additives generally recognized as safe in small quantities, but some prefer to avoid them.
