Case Study 10A: Fatigue with a Vitamin-Poor Diet

Samuel is a 63-year-old single man who works full time in a food processing plant. He has a history of esophageal cancer, which was treated successfully with anti-cancer drugs and surgery four years ago. His weight had been stable at 135 pounds until the past 6 months, in which he has experienced an involuntary weight loss of 10 pounds. He is 67 inches tall and his current BMI is 19.5. He complains of a poor appetite and being overly weak and tired. He also complains of cracks at the corners of his mouth and a chronic sore throat which concerns him, given his cancer history. His usual diet is fairly consistent. He states that he rarely eats breakfast because he starts work at 6 a.m. He eats two deli meat sandwiches, "usually pastrami or salami," and a soda at 10 a.m., and may eat a candy bar in the afternoon when he gets off work. He often prepares frozen dinners or pizza at home in the evening and routinely drinks "about 4 or 5 beers" before going to bed. Occasionally he will cook a roast and mashed potatoes. He occasionally will have milk with cereal but rarely eats vegetables or fruit. He would like to know which vitamin supplement will give him energy.

1)Based on Samuel's alcohol consumption, which B vitamin, severe deficiencies of which are called Wernicke-Korsakoff syndrome, is he lacking?                           

 

2. Given his history of cancer, Samuel might be interesting in knowing that research suggests that

3. Both Samuel's alcohol intake and his poor diet may contribute to a B6 deficiency. Which of the following foods is the best source of B6?

 

 

4. In addition to fatigue,            deficiencies are associated with anemia (large-cell type); degeneration of peripheral nerves progressing to paralysis; sore tongue; loss of appetite; and constipation.    

 

5. Given his diet and his complaints of a chronic sore throat and cracks at the corners of his mouth, Samuel may have riboflavin deficiency. Which of the following foods is the best source of riboflavin?

 

 

6. Samuel also reports small red spots on his skin, indications of spontaneous internal bleeding. This may indicate a          deficiency.

7. Samuel is interested in taking a vitamin supplement. About what percentage of U.S. adults regularly take a vitamin-mineral supplement?
