Answer:
Pellagra is a disease characterized when an individual does not get enough niacin or tryptophan.
Step-by-step explanation:
The cause of pellagra is having little niacin or tryptophan in the diet. This disease can also occur if the body cannot absorb these nutrients. This disease can appear due to:
-Gastrointestinal diseases
-Anorexy
-Excessive alcohol consumption
-Some medications such as isoniazid, 5-flurouracil, 6-mercaptopurine
This disease is very common in certain countries in Africa, where individuals eat too much natural corn. Corn does not contain enough tryptophan. Niacin is released from corn if it is soaked overnight in lime water. This practice is used to make tortillas in Central America.
