To avoid losing too much of the precious flavonoids that give dark chocolate its healthy name, Righteously Raw takes the term “minimally processed” to heart. They produce a “raw” chocolate, assuring that the cacao is never heated above 118 degrees. The low-temperature preparation means you’ll get as much flavonoid activity as possible. That’s good news, because the benefits are significant: These antioxidant compounds relax blood vessels, lower blood pressure and have an overall positive effect on heart health. Righteously Raw’s line of dark chocolate bars also includes an 80 percent cacao content Acai bar and a 90 percent cacao content Goji bar — both “superfood” berries are praised for their own strong antioxidant power. Retails for $5.50 per bar.
