Meal Planning, Dietary Guidelines and Nutritional Needs Across the Life Cycle
What this domain tests
This domain tests balanced meal planning, food-based dietary guidelines, and how nutritional needs change from infancy to old age. Questions often ask you to justify a meal choice for a named person, such as a pregnant woman, schoolchild or elderly person.
Core rules and concepts
- A balanced meal supplies energy, protein, vitamins, minerals, fibre and water in appropriate proportions. Use variety, moderation and nutrient density, not just quantity.
- Cameroon food-based guidance promotes starchy staples, legumes and nuts, vegetables and fruits, moderate animal foods, and limited oil, salt and sugar. Safe water and physical activity are part of the message.
- Meal planning steps: identify family size and needs; check budget and season; choose a staple, protein food, vegetable/fruit and fat; plan leftovers; write a shopping list.
- Infancy: exclusive breastfeeding for the first 6 months, then safe complementary foods from 6 months while breastfeeding continues.
- Pregnancy and lactation: extra protein, iron, folate, calcium and iodine; not “eating for two”. Adolescents need iron, calcium and energy for growth. Older adults need adequate protein, calcium, vitamin D and fluids, with lower energy if less active.
Worked example
Plan a low-cost lunch for a pregnant woman in a rural Cameroonian setting. Choose boiled plantain, bean stew with palm oil in moderation, dark green leafy vegetables, and a fresh orange. Reasoning: plantain supplies carbohydrate; beans supply protein, iron and fibre; greens add folate, calcium and vitamin A precursors; orange supplies vitamin C, which improves non-haem iron absorption. Palm oil adds energy and vitamin A precursors but should be limited because it is high in saturated fat. The meal is seasonal, affordable and varied.
Traps that cost marks
- “Eat for two” is wrong; pregnancy needs extra nutrients, not double energy.
- Exclusive breastfeeding means no water, other fluids or foods before 6 months unless medically indicated.
- A meal with only a staple and oil is not balanced; it lacks protein and protective foods.
- Very young children need small, frequent, nutrient-dense meals, not adult portions.
- Dietary guidelines are food-based; do not reduce them to a single nutrient.
