Preventing Nutritional Deficiency: Pellagra (B3)

Pellagra was a common nutritional deficiency in the US South as recently as the early 20th century. Because corn can be grown in much of the US, niacin (B3) is available, but not bioavailable unless it is treated with lime (calcium hydroxide). The First People found that mixing lime made from burnt crushed shellfish shells or bird shells resulted in their maize (corn) mixing better for tortillas or flatbreads, and as a result prevented pellagra by accident. You'll do the same by creating your own lime in the same manner.

Niacin is also found in many meats as well as peanuts and tomatoes.
