Frequently Asked Questions
What are Costa Rican Purple Yams?
Costa Rican Purple Yams are a cultivar of Dioscorea alata grown in Costa Rica's volcanic soils. Their deep purple color comes from anthocyanin antioxidants, and they are a nutrient-dense staple food rich in complex carbohydrates, fiber, potassium, and vitamins A and C.
How much should I eat and are they safe?
A serving of 100–150 grams (about 1/2 to 1 cup cooked) daily is a reasonable intake for health benefits. They are safe as a whole food when properly cooked. Those with kidney disease should monitor potassium intake, and raw yam should always be cooked to reduce oxalate content.
How do Costa Rican Purple Yams compare to regular yams or sweet potatoes?
Costa Rican Purple Yams contain significantly higher levels of anthocyanin antioxidants than white or yellow yams, giving them stronger antioxidant and anti-inflammatory potential. Their nutritional profile is comparable to purple sweet potatoes, though they belong to a different botanical family (Dioscoreaceae vs. Convolvulaceae).
