What was Dr Goldberger hypothesis about the cause of pellagra?
Goldberger believed that an infectious disease was unlikely to distinguish between inmates and employees or so systematically between rich and poor, and he favoured the hypothesis that a superior diet protected people from pellagra.
What is the relationship between pellagra and nutrition?
Pellagra is a nutritional disease due to deficiency of the vitamin niacin and the essential amino acid tryptophan. The clinical features of pellagra are dermatitis, diarrhea, and dementia; it is commonly known as the ‘disease of the four Ds,’ since it is also fatal – the fourth ‘D’ is death.
What did Dr Goldberger first do when he began trying to find the cure for pellagra?
The first was a prospective treatment study in a Mississippi orphanage where almost 50 percent of the orphans had pellagra. Goldberger started an enriched feeding program that included milk, meat, eggs, and fresh vegetables on one ward, keeping another ward as a control group.
What molecules or lack thereof did Dr Goldberger and the work of others identify as the cause of pellagra what was the underlying cause for the lack of these molecules?
Medical students learn pellagra as “the disease of four D’s”—dermatitis, diarrhea, dementia, and death—caused by deficiency of niacin (vitamin B3). Its protean manifestations reflect in part the requirement for nicotinamide in the coenzyme pair NAD+/NADH (Figure 1).
How was pellagra cured?
Though he identified that a missing nutritional element was responsible for pellagra, he did not discover the specific vitamin responsible. In 1937, Conrad Elvehjem, a biochemistry professor at the University of Wisconsin-Madison, showed that the vitamin niacin cured pellagra (manifested as black tongue) in dogs.
Where is pellagra most commonly found?
Pellagra is common in poor parts of the world, such as Africa and India, where corn (or maize) is a staple food. This is because corn is a poor source of tryptophan and niacin. In the United States, pellagra was prevalent in the early 1900’s in the South where corn played a large role in the diet.
Can pellagra be prevented?
The primary prevention of pellagra involves an adequate diet. Food sources of niacin and/or tryptophan include nutritional yeast, eggs, bran, peanuts, meat, poultry, fish with red meat, cereals (especially fortified cereals), legumes, and seeds.
What food causes pellagra?
Primary pellagra is caused by diets low in niacin or tryptophan. Tryptophan can be converted to niacin in the body, so not getting enough can cause niacin deficiency. Primary pellagra is most common in developing countries that depend on corn as a staple food.
Who found a cure for pellagra?
In 1937, researcher Conrad Elvehjem found that nicotinic acid, or niacin, prevented and cured pellagra in dogs. It works as well in humans. Niacin is one of the B vitamins. During the 1930s, great strides were made in understanding the way vitamins work in the chemistry of our bodies.
How can pellagra be prevented?
- The primary prevention of pellagra involves an adequate diet.
- Food sources of niacin and/or tryptophan include nutritional yeast, eggs, bran, peanuts, meat, poultry, fish with red meat, cereals (especially fortified cereals), legumes, and seeds.
Who is most at risk for pellagra?
Niacin is also known as nicotinic acid, or vitamin B3. In the United States, individuals most at risk for developing pellagra are alcoholics, as a result of malnutrition. Both alcoholism and not consuming enough green vegetables, seafood, meat, and eggs commonly cause primary pellagra.
How was pellagra stopped?
What did dr.joseph Goldberger discover about pellagra?
Dr. Joseph Goldberger discovered the cause of pellagra, a disease resulting from a diet deficient in vitamin B. Pellagra killed many poor Southerners in the early part of the 20th century.
Where can I find Joseph Goldberger’s research?

What did Abraham Goldberger discover about Shamberg’s disease?
Goldberger made several important epidemiological discoveries during this period of his career. In 1909, he published his research on Shamberg’s disease, an ailment characterized by continuous itching and elaborate skin eruptions similar to those of smallpox.
Can a person with pellagra recover from a COM based diet?
Results were dramatic; those fed a diet of fresh meat, milk and vegetables instead of a com-based diet recovered from pellagra. Those without the disease who ate the new diet did not contract pellagra. Critics, many unable to part from the germ theory of pellagra, raised doubts.
