Overview

David, a construction worker with a severe gambling problem, found himself in financial ruin and consuming a restricted, nutritionally inadequate diet. This hardship triggered an alarming health crisis marked by darkening skin, confusion, and bizarre behavior. Unbeknownst to him, he was experiencing severe niacin deficiency, also known as pellagra—a condition historically misunderstood as an infectious disease.

The video takes viewers through the fascinating history of pellagra, a disease once feared for its mysterious origins. We learn about how Dr. Joseph Goldberger's controversial experiments eventually dispelled the myth of pellagra being infectious and unveiled its true cause: a lack of niacin in the diet. These historical insights provide a rich backdrop to understanding the complexities of nutritional deficiencies today.

Amidst an era where fortification has largely eradicated such deficiencies in developed nations, David's plight serves as a stark reminder of the hidden dangers of poor diets. The video underscores the critical role of niacin and highlights societal challenges in accessing nutritious food, especially for those with dietary restrictions or financial hardships. David’s recovery story is a cautionary tale about how essential components in our diet are intricately linked to our well-being.

Chapters

• 00:00 - 01:00: David's Lifestyle and Initial Symptoms David, a 45-year-old construction worker, is experiencing financial difficulties due to his frequent losses in sports betting, which consumes most of his paycheck. His pride prevents him from seeking help from a food bank, and his gluten sensitivity limits his dietary options. As a result, he relies on a restricted diet of cheap, high-calorie foods that can be bought in bulk. David begins to notice troubling physical symptoms, including his skin turning dark brown and peeling, especially on his face and neck.
• 01:00 - 03:00: David's Disappearance and Hospital Admission David, a construction worker, initially dismisses damage on his arms as sun damage, unable to afford sunscreen. One day, he mysteriously disappears from the site and can't be reached by phone. His job is reassigned and his location unknown until a month later when he is spotted looking disheveled downtown by a former co-worker.
• 03:00 - 05:00: Initial Hospital Tests and Misdiagnosis The chapter "Initial Hospital Tests and Misdiagnosis" follows the story of David, who was found muttering and talking to himself, raising concerns about his safety. The police bring him to the emergency department for assessment. Despite his stable vitals and no fever, David appears emaciated with dark, peeling skin on his face, neck, and forearms. He had noticed this condition months earlier. Throughout the assessment, David remains confused and exhibits disorganized thoughts.
• 05:00 - 07:00: David's Deterioration and Continued Testing In this chapter, David is experiencing a significant decline in his mental state. During an assessment, he was very sluggish in responding to questions and displayed signs of hallucinations, reacting to non-existent stimuli. At one point, David covered his head with a sheet and laughed uncontrollably. These symptoms might suggest an issue like substance use or a mental health condition such as schizophrenia, but the narration points out the importance of considering a broad range of medical causes for such symptoms, including liver disease, brain infections, autoimmune diseases, and others.
• 07:00 - 10:00: Diagnosis of Pellagra and Explanation This chapter discusses the process of diagnosing David's condition which involved ruling out vitamin deficiencies and potential causes through various tests, as documented in a published case. The author mentions additional tests they would have considered if they were the attending physician, including a CT scan of the head, thyroid testing, and a urine drug test. Despite all tests returning normal results, the Emergency Physician suspected a primary mental health issue, leading to David's admission to the inpatient care.
• 10:00 - 13:00: Historical Context of Pellagra Research The chapter discusses the historical context of pellagra research, focusing on a case study involving a patient named David. Initially diagnosed with undetermined psychosis, David was treated with low-dose antipsychotic medication. However, his condition worsened considerably within days, manifesting severe diarrhea, vomiting, and dangerously low blood pressure, while his mental status did not improve. This case highlights the complexities and initial misdiagnoses often faced in understanding and treating pellagra.
• 13:00 - 15:00: Understanding Niacin in Diets and Treatments The chapter delves into the case study of a patient in a catatonic state characterized by lack of speech, poor appetite, and minimal movement, leading to an urgent transfer to an acute medical unit. Initial stabilizing treatments included fluids and electrolytes, and initial diagnostic tests such as blood work suggested dehydration but did not offer specific insights. A CT scan revealed abnormalities in the cerebral cortex and areas surrounding the cerebral ventricles, yet these findings remained inconclusive and did not lead to a clear diagnosis. Consequently, the internist reviewed the patient's chart thoroughly to piece together more information.
• 15:00 - 18:00: David's Recovery and Broader Implications In the chapter titled 'David's Recovery and Broader Implications,' the narrative unfolds around the discovery of diagnostic clues that eventually aid in piecing together David's medical mystery. The chapter details symptoms including dermatitis, skin darkening, altered mental status, and diarrhea. These symptoms lead the medical team to suspect a specific condition. They perform a crucial test—a 24-hour urine collection—which reveals a critically low level of n-methyl nicotinamide, confirming the diagnosis of pellagra. Pellagra is caused by a severe deficiency of niacin. This diagnosis is key to understanding David's condition and represents a significant breakthrough with wider implications.

• 00:00 - 00:30 meet David a 45-year-old construction worker who was struggling financially week after week he spent most of his paycheck on sports betting and he kept losing money too proud to go to a food bank and limited by his gluten sensitivity he ended up eating a very restricted diet focusing on cheap calorie-dense foods that he could buy in bulk one day when he was getting ready for work he noticed that his skin was turning a dark brown color and starting to peel particularly on his face neck
• 00:30 - 01:00 and forearms he figured it was just sun damage from working outside and since he couldn't afford sunscreen he just ignored it a few months went by and then something unusual happened in the middle of a workday David wandered off the construction site without a word to anyone and just disappeared he never answered his phone when his supervisor called to check in so his job was given to someone else and David's whereabouts remained a mystery about a month later one of its co-workers was walking downtown and noticed a disheveled man
• 01:00 - 01:30 muttering and talking to himself could that be David they called the police and when they arrived David was clearly agitated and Confused concerned for his safety the police brought him into the emergency department to be assessed in triage his vitals were stable with no fever but he looked emaciated and the Emergency Physician noted dark peeling skin on his face neck and forearms the same thing David had noticed a few months ago David was confused his thoughts were disorganized organized and
• 01:30 - 02:00 he was very slow to answer questions it was also clear that he was hallucinating reacting to things that he was hearing and seeing that weren't actually there at one point in the assessment he covered his head with a sheet and started laughing uncontrollably in a situation like this you might assume that it's related to substance use or a mental health condition like schizophrenia and while that can often be the case there's also a long list of possible medical causes that need to be considered from liver disease to brain infections autoimmune diseases and even
• 02:00 - 02:30 some vitamin deficiencies so to check for some of these causes David's doctor ordered these tests now this list of Investigations is taken directly from the published case I will say that if I were the one looking after David at this point I also would have ordered a CT scan of the head thyroid testing and a urine drug test in any case all these tests came back normal and the Emergency Physician suspected that the primary issue was a mental health condition so David was admitted to the inpatient
• 02:30 - 03:00 psychiatric unit with a diagnosis of psychosis nyd not yet diagnosed and the psychiatrist started him on a low-d do antis pycho medication but just 3 days later the psychiatrist urgently paged the internist on call David's condition had seriously deteriorated he had developed severe diarrhea and vomiting and his blood pressure was dangerously low and to make matters worse his mental status hadn't improved at all it had just changed DAV David was in a nearly
• 03:00 - 03:30 catatonic State not speaking not eating and barely moving so he was urgently transferred to the acute medical unit where he was stabilized with fluids and electrolytes urgent blood work was ordered which showed some signs of dehydration but no other Clues finally they ordered a CT scan of his head which showed abnormalities of the cerebral cortex and diffus spots around the cerebral ventricles definitely abnormal but also not pointing to a specific diagnosis so the internist combed through David's chart looking for
• 03:30 - 04:00 Diagnostic Clues and that's when the pieces of the puzzle started coming together dermatitis that darkening of his skin altered mental status and now diarrhea could it be they ordered one last test that they hoped would confirm the diagnosis a few days later a 24-hour urine collection showed an undetectably low level of n methyl nanomite which confirmed their suspicion David had pellagra which is caused by severe nasin
• 04:00 - 04:30 deficiency you've probably heard of nasin by its other name vitamin B3 although it's not a vitamin we think about often because it's found in so many things like meat fish nuts nutritional yeast whole grains and fortified foods and yet n deficiency or pelra used to be a global Health crisis with serious outbreaks all around the world including in the United States but more on that later so what exactly makes
• 04:30 - 05:00 nasin so important well after it gets absorbed in the small intestine nasin gets converted to NAD which I like to think of as the body's energy helper it's involved in more than 400 enzyme reactions to turn food into energy fueling everything from your muscle movements to thought processing NAD is also needed to repair damaged DNA and to maintain the health of our cells in short nyin is vital for our survival and you know it's important when our body has a backup plan in case there's a
• 05:00 - 05:30 nasin deficiency your body can convert the amino acid tryptophan into nin with the help of vitamin B6 B2 and iron unfortunately this conversion is really inefficient it takes about 60 Mig of tryptophan to make just 1 milligram of niin and David's Ultra lowcost gluten-free diet was also deficient in tryptophan which is what led him down this dangerous path when nyson is missing the consequences are severe and you can recognize the four DS of pgra just like we saw with David the first
• 05:30 - 06:00 symptom to usually show up is dermatitis this is because the skin has really high energy demands without enough NAD skin cells can't generate enough energy to repair themselves this leaves the skin vulnerable to things like UV damage so it usually starts with a rash on sun-exposed areas like the face or on the arms and it may actually look like a sunburn at first but over time it'll become dark rough and scaly and this is actually where the condition got its name pgra comes from the Italian term
• 06:00 - 06:30 for rough skin and one classic skin finding is called kazal necklace which is a dark hyperpigmented band around the neck but pagora doesn't stop at the skin the cells lining our intestines also replicate really quickly and have high energy demands so they're really sensitive when there's not enough NAD and when those cells don't function properly you also don't absorb nutrients as efficiently this leads to abdominal pain nausea and severe diarrhea which then makes nutritional deficiencies even worse
• 06:30 - 07:00 which puts you in this really vicious cycle and it just keeps getting worse the lack of energy for important neural Pathways in our brain leads to dementia with confusion memory loss and even psychosis as we saw in this case and if it's left untreated It ultimately leads to the last D death okay now I've got to tell you about the drama in the scientific Community when pel's true cause was uncovered I'll warn you that some of the experiments in this story had questionable ethics but the results

• 07:30 - 08:00 an infectious disease like the plague and with a 40% mortality rate people were terrified of catching it part of the reason they thought it was infectious is because cases were geographically clustered in poor rural areas of the Southern United States this is Dr Joseph goldberger a physician and public health official who made a really important observation he noticed that in orphanages and asylums where pgra was rampant the caregivers weren't getting sick which is not what you would expect if the condition was contagious he also
• 08:00 - 08:30 noticed a significant difference in their diet the orphans and patients were typically surviving on calorie dense foods like cornmeal molasses and a bit of pork fat which was the typical diet for poor Southerners at the time in contrast the caregivers were eating a really well-rounded diet and he suspected this was the root of the issue so he tested his theory by improving their diets and adding fresh milk fresh meat and vegetables and the results were incredible people started recovering
• 08:30 - 09:00 from pelra and in some cases people's mental status improved so much that they were able to be discharged home from the Asylum which was a really rare thing in those days but despite these amazing findings nobody listened to him he couldn't convince the medical establishment that pagro was a nutritional deficiency and not an infection so his next study was a bit more dramatic and it definitely wouldn't get research ethics board approval today he enlisted prisoner volunteers to eat a nutrient poor diet and what do you know many of them developed pelra but people
• 09:00 - 09:30 were still skeptical so he devised the most outrageous experiment you could imagine he held what he called filth parties where he injected the blood of patients with pgra into the deltoid of healthy volunteers including himself and his wife and he took it even further than that he also mixed bodily fluids from patients with pellagra into their food and they ate it not once did they do a party like this but seven
• 09:30 - 10:00 times so gross but you know it was in the name of science unfortunately Dr goldberger didn't live long enough to see his theories confirmed and I understand that's not because of the parties 16 years after those Infamous filth parties researchers isolated n in the lab and they were finally able to prove without a shred of doubt that pagro was caused by a nutritional deficiency but here's the weird thing do you remember how I told you that the people who were getting pigra were eating a lot of of corn-based foods well
• 10:00 - 10:30 corn technically contains enough nasin to meet your nutritional needs so why are these people getting sick okay so here's some culinary science and the last piece of our puzzle unlike other grains niin in corn is bound tightly to compounds inside the corn making it nearly impossible for a body to absorb it for nasin to be released the corn needs to be soaked and cooked in a special alkaline solution a process called NYX talization this technique dates back to the Aztec and it remains an important part of Mexican Cuisine
• 10:30 - 11:00 dried corn kernels are boiled and then soaked in water mixed with lime a type of calcium which softens the kernels and makes the nutrients more accessible this is actually how the dough for tortillas and tamales is made and it's because of this practice that Mexico didn't suffer widespread epidemics of pgra unlike parts of Europe and the United States where people ate untreated corn and couldn't absorb the nasin but this all changed in the 1940s when the FDA mandated that certain vitamins and minerals get added to flour including
• 11:00 - 11:30 vitamin B1 B2 B3 and iron so if you're eating something or baking something that has enriched flour in it you can be reassured that you're getting nin and because of policies like this around the world these days it's exceedingly rare to see pgra in developed countries we typically only see it in cases where people are really malnourished like alcohol abuse post bariatric surgery anorexia or a malabsorptive condition so how much nasin do you actually need in general it's about 16 Mig per day for
• 11:30 - 12:00 men and 14 Mig per day for women that's about 3 to eight servings of plant-based foods like nuts and legumes or two to three servings of meat and fish or 10 slices of fortified Wonderbread so let's go back to David and consider his diet he primarily ate oatmeal white rice with margarine and sometimes some rice noodles and unlike wheat flour most gluten-free flowers aren't fortified with nin so David wasn't getting anywhere near the amount of nasin that he needed for fortunately his condition
• 12:00 - 12:30 was diagnosed before it was too late he was treated with niin supplements in addition to a bunch of other vitamins and minerals because he was so malnourished his recovery was a long process but a few weeks after the supplements were started David's mind started becoming more clear he was speaking again and the dark patches on his face and arms started to fade in the end it took six long months in the hospital overcoming physical and psychological challenges along the way before David had recovered enough that he could go home David's story is a
• 12:30 - 13:00 powerful reminder of how closely our health is linked to what we eat and for people facing Financial challenges it can be really difficult to prioritize nutritious food when less healthy options are often more affordable especially if you have food allergies or sensitivities so when we're talking about nutritional deficiencies we're not just talking about health and isolation we're talking about much bigger issues that we're facing in society and that's just as relevant today as it was in the 1920s now if you enjoyed this video check out this one next it's a real
