Q&A

• Can you provide an example of the impact of niacin deficiency?

  A case study illustrates the impact of severe niacin deficiency, highlighting the importance of a nutritious diet and the challenges of prioritizing nutritious food, especially for individuals with food allergies or financial constraints.

• How rare is niacin deficiency, and what are the recommended daily intakes?

  Niacin deficiency is rare in developed countries but can occur in cases of malnutrition. The recommended daily intake is 16mg for men and 14mg for women.

• What did Dr. Goldberger do to prove that pellagra was caused by a nutritional deficiency?

  Dr. Goldberger conducted controversial experiments to prove that pellagra was caused by a nutritional deficiency, leading to the discovery of niacin and the importance of nixtamalization in processing corn, which helped prevent widespread pellagra epidemics.

• What did Dr. Joseph Goldberger discover about pellagra, and how did he prove his theory?

  Dr. Joseph Goldberger observed a connection between nutrition and pellagra, suspecting a dietary cause. He tested his theory by improving the diets of those with pellagra, resulting in remarkable recoveries, indicating a link between nutrition and the disease.

• What is the role of NAD in the body, and what are the consequences of its deficiency?

  NAD is essential for the body, involved in enzyme reactions, DNA repair, and cell health. Its deficiency leads to severe consequences such as dermatitis, intestinal issues, and neurological problems.

• What was the confirmed diagnosis for David's condition?

  Further tests revealed undetectably low levels of n-methyl-nicotinamide, confirming a diagnosis of pellagra caused by severe niacin deficiency.

• What led to the deterioration of David's condition?

  David's condition deteriorated, leading to severe diarrhea, vomiting, and dangerously low blood pressure despite the low-dose antipsychotic medication.

• How was David initially diagnosed, and what treatment did he receive?

  David was initially diagnosed with psychosis nyd and treated with low-dose antipsychotic medication due to his symptoms.

• What were David's initial symptoms?

  David initially experienced dark peeling skin, disorganized thoughts, and hallucinations, along with other concerning physical and mental symptoms.

• 00:02 Meet David, a struggling construction worker who developed concerning physical and mental symptoms. His condition leads to a series of medical tests to identify the underlying cause.
• 02:16 David was initially diagnosed with psychosis nyd and treated with low-dose antipsychotic medication. However, his condition deteriorated, leading to severe diarrhea, vomiting, and dangerously low blood pressure. A CT scan showed abnormalities, and further tests revealed undetectably low levels of n-methyl-nicotinamide, confirming a diagnosis of pellagra caused by severe niacin deficiency.
• 04:38 NAD is essential for the body, involved in enzyme reactions, DNA repair, and cell health. Deficiency leads to severe consequences such as dermatitis, intestinal issues, and neurological problems.
• 06:43 In the early 1900s, pellagra was initially thought to be an infectious disease with a high mortality rate. Dr. Joseph Goldberger observed that the caregivers in orphanages and asylums with rampant pellagra weren't getting sick, leading him to suspect a dietary cause. He tested his theory by improving their diets, resulting in remarkable recoveries, but faced resistance from the medical establishment.
• 08:53 Dr. Goldberger conducted controversial experiments to prove that pellagra was caused by a nutritional deficiency. The discovery of niacin and the importance of nixtamalization in processing corn prevented widespread pellagra epidemics.
• 11:08 Niacin deficiency can have severe consequences; it's rare in developed countries but can occur in cases of malnutrition; recommended daily intake is 16mg for men and 14mg for women; a case study illustrates the impact of niacin deficiency and the importance of a nutritious diet.
