Iron and Protein for a Plant-Forward Cafeteria
A college dining hall wants to cut beef purchases by 40% and offer plant-forward entrées at every meal. The dietitian notes that many students are vegetarian or vegan, some are athletes in training, and a subset report fatigue. The current menu's plant options are pasta with marinara, a bean burrito, and a salad bar. Student feedback says the plant entrées are 'not filling.' The kitchen has one combi oven, one tilt skillet, and no ability to add staff hours.
1. Identify the nutrition principles that should guide the redesign, and explain why the current plant options may leave students unsatisfied.

Key principles:
- Protein adequacy and distribution. Plant entrées should deliver meaningful protein per serving and be spread across the day, especially for athletes.
- Iron bioavailability. Non-heme iron is absorbed less efficiently; pairing with vitamin C sources and avoiding tea/coffee at the meal improves absorption.
- Energy density and satiety. Pasta with marinara and a plain salad are low in protein and fat, so they are less satiating.
- Complementary proteins and variety. Legumes plus grains, tofu, tempeh, and dairy/fortified alternatives broaden the amino acid and micronutrient profile.
- B12, zinc, calcium, omega-3 deserve attention for vegan students.
Why students feel unsatisfied: the current options are grain- and vegetable-heavy with little protein or fat, and they are repetitive. 'Not filling' is a legitimate nutrition signal, not a preference complaint.
2. Using only the existing equipment and staff hours, propose three specific menu changes and explain the nutrition rationale for each.

- Tofu or tempeh burrito bowl in the combi oven - roast marinated tofu with peppers and onions; serve over rice with black beans and a lime-cilantro slaw. Rationale: raises protein per serving, adds vitamin C to aid non-heme iron absorption, and is batch-cookable.
- Lentil and chickpea stew in the tilt skillet - simmer with tomatoes and greens; serve with fortified grain. Rationale: legume-based protein, iron, and fiber; tomato vitamin C improves iron uptake; scales without added labor.
- Upgrade the salad bar with a protein station - roasted chickpeas, edamame, cubed firm tofu, sunflower seeds, and a fortified plant yogurt dressing. Rationale: turns a side into a meal, adds protein and fat for satiety, and requires no new equipment.
All three use existing equipment, batch production, and minimal added labor.
3. A student athlete who eats vegan reports fatigue. What should the dietitian assess and recommend, and what is out of scope?
Read the worked answer
Assess: total energy intake (fatigue often reflects undereating), protein quantity and timing, iron status (ferritin, hemoglobin via referral), B12 status, vitamin D, and whether training load recently increased. Screen for other causes and refer to a physician for labs.
Recommend: energy-dense meals and snacks around training; iron-rich plant foods paired with vitamin C; avoid tea/coffee with iron-containing meals; a fortified B12 source or supplement; consider a fortified plant milk with calcium and vitamin D.
Out of scope: diagnosing iron-deficiency anemia or prescribing therapeutic doses. The dietitian provides nutrition guidance and coordinates with the medical team.
