Menu Planning and Nutrition Calculation

A menu is a plan of the dishes for each meal. A good menu is balanced (all five food groups), enough in energy, fair in cost, and suits season, taste and time. To check it, use a food table: nutrient in a portion = grams ÷ 100 × value per 100 g, then add up the day and compare it with the body's need.

🎬 Step-by-step story

  1. A menu is a plan. Here are three plates: breakfast, lunch and dinner. We decide the dishes before we cook.
  2. Put all five food groups on the plate: grain, pulses or eggs, vegetables, fruit and milk. That makes the meal balanced.
  3. How much energy is on the plate? The table says 100 g of cooked rice gives 130 kcal. For 150 g, do 150 ÷ 100 × 130 = 195 kcal.
  4. Add all the meals of the day: 450 + 700 + 250 + 600 = 2000 kcal. Compare this with what the body needs. Equal means a good plan.
  5. Also check the shares of energy (about 55% carbohydrate, 30% fat, 15% protein), the cost, the time and the season.
  6. Your turn: move the sliders to change the grams of rice, dal, vegetables and milk. Watch the total and make a lunch of about 600 to 700 kcal.

🤔 Common doubts, cleared

Why divide by 100 in the calculation?

Because the table shows values for 100 g. If you eat 150 g, that is 1.5 times 100 g, so you multiply the value by 1.5.

Do I plan each meal or the whole day?

Plan the whole day. One meal may be a little low in something, and another meal can make up for it.

Is 2000 kcal right for everyone?

No. It is only a rough figure for a teenager or an adult. Children, older people and very active people need different amounts.

Why are the calculated values only estimates?

Tables give average values. Real foods differ in variety, ripeness and how they are cooked.

Which food group do I add first?

Start with the staple your family eats, then add pulses or eggs, vegetables, fruit and milk to complete the plate.

How do I fix a menu with too little protein?

Add a pulse, egg, curd, milk, sprouts or fish. Then calculate again.

Meaning of menu planning

A menu is a list of the dishes served at a meal. Menu planning means deciding these dishes in advance for a day, a week or an event.

Why plan? A plan gives balanced food, saves money and time, reduces food waste, and avoids eating the same thing every day.

What to think about when you plan

The five food groups and the plate

Put these on the plate: a staple (rice, roti, millet) for energy; pulses, eggs, fish or meat for building the body; vegetables and fruit for vitamins, minerals and fibre; and milk or curd for calcium. Use a little oil, ghee or nuts for fat. Plan so that every meal has at least three groups and the whole day has all five.

Nutrition calculation

A food composition table lists the energy and nutrients in 100 g of each food. To find the value in your portion:

Value in portion = grams eaten ÷ 100 × value per 100 g

Example: cooked dal gives about 110 kcal and 7 g protein per 100 g. For 200 g: energy = 200 ÷ 100 × 110 = 220 kcal; protein = 200 ÷ 100 × 7 = 14 g.

Steps

  1. Write each food and its grams.
  2. Find the value per 100 g in the table.
  3. Multiply and divide as above for each food.
  4. Add up for the meal, then for the day.
  5. Compare with the need of that person (about 2000 kcal for a teenager; it changes with age, size and activity).

Energy from nutrients

1 g carbohydrate gives 4 kcal, 1 g protein gives 4 kcal and 1 g fat gives 9 kcal. A healthy mix is about 55% of energy from carbohydrate, 30% from fat and 15% from protein. Values in tables are averages, so your answer is a good estimate, not an exact number.

Check, then improve the menu

After calculating, ask: is the energy near the need? Is protein enough? Is any group missing? Too costly? Too long to cook? If yes, change a portion or swap a food (for example, add a pulse if protein is low, add a fruit if vitamins are low). Then calculate again. Good menu planners repeat this loop until the plan fits.

Key formulas and definitions

Worked examples

1. Find the energy in 200 g of cooked rice (130 kcal per 100 g).

200 ÷ 100 × 130 = 2 × 130 = 260 kcal.

2. A lunch has 150 g rice (130 kcal/100 g), 100 g dal (110 kcal/100 g) and 100 g vegetables (50 kcal/100 g). Find the total energy.

Rice: 1.5 × 130 = 195. Dal: 1 × 110 = 110. Vegetables: 1 × 50 = 50. Total = 195 + 110 + 50 = 355 kcal.

3. Find the protein in 250 ml of milk (3.3 g per 100 ml).

250 ÷ 100 × 3.3 = 2.5 × 3.3 = 8.25 g.

4. A day has 450, 700, 250 and 600 kcal in four meals. The need is 2200 kcal. How far is the plan from the need?

Total = 450 + 700 + 250 + 600 = 2000 kcal. Need − plan = 2200 − 2000 = 200 kcal short. Add a snack of about 200 kcal.

5. A meal has 60 g carbohydrate, 20 g protein and 15 g fat. Find the energy and the % from fat.

Carbohydrate: 60 × 4 = 240. Protein: 20 × 4 = 80. Fat: 15 × 9 = 135. Total = 455 kcal. Fat share = 135 ÷ 455 × 100 ≈ 29.7%, about 30%.

6. A school feeds 120 children. Each gets 80 g cooked dal. How many kg of cooked dal are needed, with 10% extra?

120 × 80 = 9600 g = 9.6 kg. 10% extra = 0.96 kg. Total = 9.6 + 0.96 = 10.56 kg.

Frequently asked questions

What is menu planning?

It is deciding the dishes for meals in advance so that the food is balanced, affordable, tasty and not wasted.

For each food, multiply the grams eaten ÷ 100 by the value per 100 g in the food table, then add the results.

What factors affect menu planning?

Age, health, activity, budget, season, time, cooking tools, taste and culture.
