Menu Planning for a Vegetarian Teenager
A 15-year-old girl in your food and nutrition class has recently become a vegetarian for ethical reasons. She lives with her family who eat meat, and her mother is concerned about her getting enough protein and iron. The girl is active in sports and needs about 2,200 calories per day. She dislikes lentils and beans but likes tofu, eggs, and dairy. The family has a moderate income and shops weekly at a local supermarket. You need to help her plan a week's evening meals that are nutritionally balanced, practical for the family (who will eat the same base meal with meat added), and culturally familiar (Caribbean cuisine). She also needs to ensure she gets enough vitamin B12 and omega-3 fatty acids.
1. Design a sample evening meal plan for one week that meets the girl's nutritional needs, considers her food preferences, and is practical for her family. Explain how each meal contributes to protein, iron, vitamin B12, and omega-3 intake.

Monday: Tofu and vegetable stir-fry with brown rice. Protein from tofu; iron from tofu and vegetables; add fortified nutritional yeast for B12. Tuesday: Egg curry with roti and spinach. Eggs provide protein and B12; spinach adds iron. Wednesday: Cheese and vegetable quiche with salad. Dairy provides protein, B12, and calcium. Thursday: Bean-free option: chickpea and potato curry (if she dislikes beans, chickpeas may be acceptable; otherwise use tofu). Include fortified plant milk for B12. Friday: Fish-free? She is vegetarian, so include omega-3 from flaxseed oil in salad dressing or walnuts. Meal: pasta with tomato sauce and walnuts, plus a side of broccoli. Saturday: Vegetarian lasagna with lentils? She dislikes lentils, so use soy mince (fortified with B12) and cheese. Sunday: Rice and peas (using red kidney beans may be disliked; substitute with tofu cubes) with callaloo. To ensure B12: include fortified foods like nutritional yeast, fortified plant milk, or eggs/dairy daily. Omega-3: flaxseed, walnuts, chia seeds. Iron: pair with vitamin C (e.g., citrus, tomatoes) to enhance absorption. Practical for family: base meal is vegetarian; family can add grilled chicken or fish on the side. Portion sizes: include energy-dense foods for sports. This plan meets protein needs by including tofu, eggs, dairy, and soy products at each meal.
2. Discuss how you would address the mother's concerns about protein and iron, and provide advice on how the girl can maintain her vegetarian diet while eating with her family. Include specific strategies to increase iron absorption and ensure B12 intake.

Address concerns by explaining that plant proteins can meet needs if varied. Provide examples: tofu, eggs, dairy, soy mince. For iron: plant sources like spinach, fortified cereals, and tofu; pair with vitamin C-rich foods (e.g., orange juice, tomatoes, peppers) to enhance absorption; avoid tea/coffee with meals as tannins inhibit iron. For B12: include fortified foods (plant milk, nutritional yeast, some cereals) or eggs/dairy; consider a supplement if needed. Family meals: cook a base vegetarian dish and add meat separately for others; or choose dishes that are naturally vegetarian like macaroni pie, rice and vegetables. Encourage the girl to help plan and cook. Suggest keeping a food diary to monitor intake. Recommend consulting a doctor or dietitian. Emphasise that a well-planned vegetarian diet can be healthy and adequate for sports.
