How to eat it
Eat raw or lightly roasted; the high heat and processing used to make conventional chocolate destroys much of the flavonoid content nibs retain.
Pairs well with
Vitamin C foods, supports absorption of cacao's plant-based iron
A small amount of fat (nut butter), pairs well and helps absorb fat-soluble compounds
Storage
Store in an airtight container in a cool, dark place; keeps for up to a year.

Evidence
C
Flavanol cardiovascular evidence is reasonable, but the contaminant picture is the more actionable finding for this food.
Study dose vs. serving
Median concentrations sit below Prop 65 limits, so outlier products drive risk. A Tulane 155-sample study concluded one ounce/day poses no adult health risk.
Frontiers in Nutrition 2024 (PMC11321977): 72 US products 2014-2022; 43% exceeded California Prop 65 for lead, 35% for cadmium, 0% for arsenic.
Use caution if
You're sensitive to caffeine or theobromine, cacao contains both stimulants
You take MAOI medications, cacao contains trace tyramine-like compounds worth discussing with a doctor

Watch
CADMIUM AND LEAD. Consumer Reports 2022 found 23 of 28 dark chocolate bars exceeded Prop 65 levels; the 2023 follow-up found 71% of 48 products above concern levels. Cadmium comes from soil (higher cocoa % = more), lead from post-harvest drying. Risk concentrates in high-intake consumers and small children.
