While nutrition, budget and time are commonly cited factors, meal planning is shaped by several other practical considerations as well. Three such factors are discussed below.
1. Age and composition of the family: A household with young children, elderly members, or someone managing a health condition like diabetes needs meals adjusted to each person's specific requirements, whether that means softer textures for a toddler, lower sugar for a diabetic, or higher protein for a growing teenager. Meal planning has to account for these different needs within the same household.
2. Availability and seasonality of food items: What can realistically be planned depends on what is locally and seasonally available. Planning meals around fruits and vegetables that are in season is usually cheaper and fresher than relying on items that must be brought in from far away or stored for long periods, so seasonal availability directly shapes the week's menu.
3. Food habits, preferences and cultural or religious practices: A family's customary diet, whether vegetarian, particular religious food restrictions, or simply strong likes and dislikes among family members, has to be respected for the meal plan to actually be followed. A nutritionally ideal meal that nobody wants to eat achieves little in practice.
Therefore, besides nutrition, budget and time, meal planning is also shaped by the age and composition of the family, the seasonal availability of food, and the household's food habits and cultural preferences.
