Per capita production is greatest in countries where sweet potatoes are a staple of human consumption, led by Papua New Guinea at about 500 kg (1,100 lb) per person per year, the Solomon Islands at 160 kg (350 lb), Burundi and Rwanda at 130 kg (290 lb) and Uganda at 100 kg (220 lb).
About 20,000 tonnes of sweet potatoes are produced annually in New Zealand, where sweet potato is known by its Māori name, kūmara. It was a staple food for Māori before European contact.
My note: Epidemiologically, we could study impact of eating sweet potato on health. Sweet potato has extremely high Vitamin A and beta-carotene. We could study impact of such high levels these nutrients on health by studying health in the above countries and other south American countries which eat high levels of sweet potato and other Vitamin A and beta-carotene rich foods like squash.
