Starchy root tuber with brown, hairy skin and white-to-purple flesh. Cooks to a creamy, slightly sweet, potato-like texture. Single cup provides 187 calories, 7g fiber, and significant manganese, vitamin E, vitamin B6, and copper. Contains substantial resistant starch when cooked and cooled — a fiber type that feeds gut bacteria.
Available at Caribbean, West African, Latin (as malanga), and Asian groceries. Increasingly at mainstream markets in diverse cities. Affordable per pound — cheaper than potatoes per calorie. Frozen pre-cubed dasheen available at some Caribbean markets.
Cooked-and-cooled dasheen develops type-3 resistant starch — a fermentable fiber that feeds beneficial gut bacteria (Bifidobacteria and Akkermansia), producing butyrate. Butyrate is the primary fuel for colonocytes, reduces colonic inflammation, lowers postprandial glucose, and supports the gut-brain axis. For Black Americans facing colorectal cancer at higher rates than any other group, the resistant starch from cooked-cooled dasheen is an underappreciated dietary intervention. The dasheen leaves also provide calcium, iron, vitamin C, and fiber — eating both root and leaf is whole-plant nutrition the way ancestors practiced it.
Peel and chop into 1-inch chunks. Boil 25-35 minutes until fork-tender. Use in soups (Caribbean callaloo soup, Louisiana gumbo), mash like potatoes, fry as chips. To maximize resistant starch: cook, cool in fridge overnight, then reheat gently. The cooling forms the resistant starch crystals that survive reheating.
