I’d be more worried about the coffee than a 1/4 tsp of cacao powder. I fast to maintain metabolic flexibility, a little fat burning, autophagy, stem cell promotion, and mTor suppression. This probably is not an issue at 1/4 tsp of powder, but I recently learned a few tidbits about cacao. First, it is a good source of PQQ, which promotes mitochondrial biogenesis and weight loss as a result. However, cacao powders from Latin America, especially Peru, can be somewhat high in cadmium, and sometimes lead, while cacao powders from W. Africa tend to be lower in these heavy metals. The Volupta brand at Costco is sourced from Peru and Equador according to the bag, and has been independently tested as one of the brands higher in cadmium, and low average in desirable polyphenols. Surprisingly, Target’s Good and Gather brand of cocao powder tested well in both catefories, so I have switched… JFYI.
