Mr. John Davis is a 68-year-old retired engineer who is concerned about his immune health and maintaining strong bones as he ages. He has recently experienced more frequent colds and has noticed some discomfort in his joints. His healthcare provider suggested that he pay closer attention to his nutrition, especially certain vitamins and minerals known to support immune function and bone health. John is physically active and tries to eat a balanced diet, but he wonders if he is getting enough of the nutrients his body needs. Below is what John usually eats in a day: Breakfast: oatmeal, slice of white toast with butter, and black coffee Midmorning snack: apple and a handful of crackers Lunch: turkey sandwich (white bread, deli turkey, American cheese, mayonnaise, lettuce, and tomato), small handful of potato chips, and diet soda Afternoon snack: granola bar Dinner: spaghetti with jarred marinara sauce, garlic bread, and 1 glass of red wine Evening snack: small handful of pretzels and a cup of herbal tea
