How to carry out nutritional analysis
-
A nutritional analysis is used to find out the nutrient values of a recipe, meal or diet
-
Each ingredient has a nutrient value which can be sourced from food tables or nutritional analysis software
-
Nutritional analysis can be used to plan and modify recipes, meals and diets to reflect the nutritional guidelines for a healthy diet
-
In the UK, the Eatwell Plate (opens in a new tab) should be referred to when planning meals, thus recipes and diets should be modified to reflect this
-
Ingredients and cooking methods can be changed to ensure meals are nutritionally balanced, e.g.:
-
Salt and sugar can be replaced with a variety of herbs and spices, or natural sweeteners such as dates or honey
-
Wholegrain carbohydrates can be used instead of white rice and pasta which will increase fibre intake
-
Leaner cuts of meat can be used instead of high-fat choices such as sausages
-
-
Portion size can be controlled to follow recommended daily energy intakes
-
Overall diet can be modified to suit a person’s needs e.g.
-
Someone who is obese may need a diet with lower fat intake
-
A diabetic person will need to manage and modify the sugars and carbohydrates consumed
-
A vegan diet will need careful consideration to replace proteins found in meat and ensure daily requirements are met
-
-
Using food tables for nutritional analysis
-
Food tables list ingredients alphabetically or by group to show the amount of nutrients per 100 g of food
-
The nutrient value may need to be converted into the quantity required for a specific recipe (which may not be 100 g)

Worked Example
A recipe requires 85 g of lentils.
Calculate the amount of carbohydrate contained in the lentils for this recipe.
Step 1 Use a food table (above) to determine the amount of carbohydrate in 100 g of lentils
Lentils contain 20 g carbohydrate per 100 g
Step 2 Divide by 100 g to determine grams of carbohydrate per 1 g
20 / 100 = 0.2 g carbohydrate per 1 g
Step 3 Multiply by 85 g
0.2 x 85 = 17 g carbohydrate in 85 g of lentils
Using nutritional analysis software
-
Many online nutritional software are available to determine the nutritional analysis of food
-
The food ingredient is searched for
-
The mass or volume required for recipes or diets can be adjusted
-
Portions per person can also be calculated
-
The nutrients and energy for the specific portions and weights required will be shown
-
Some programs allow comparisons of nutritional values to recommended guidelines
-
Examiner Tips and Tricks
You can easily convert between millilitres and grams for different recipes or nutritional analysis data e.g. 100 g milk = 100 ml of milk
