Everyday nutrition: five things to help you understand food

Short answer: Food provides both energy and nutrients. To understand everyday nutrition, look at the whole picture: energy, protein, fat, carbohydrates and fibre, as well as vitamins and minerals. A high value for one substance does not describe the entire diet.

1. Energy and nutrition are two different questions

Energy describes what food provides in kilocalories or kilojoules. Nutrients describe its composition in more detail. Two products can provide the same energy but contain different amounts of protein, fat, fibre and other substances. Both quantity and composition therefore matter.

The body's energy needs vary. They are affected by factors including basic bodily functions and physical activity. A reference value on packaging is therefore not a measured requirement for you. The NNR 2023 chapter on energy describes that distinction.

In everyday life: when comparing two lunch options, start with the amount you actually use and everything included alongside it. Drinks and extras do not disappear just because the main product has a clear nutritional declaration.

2. Protein is one part of food's composition

Protein consists of amino acids and has several functions in the body. It is found in both animal and plant foods. Beans, lentils, tofu, eggs, fish and dairy products are examples of foods that can provide protein. The content varies between products and quantities.

A protein figure alone cannot determine what a meal contains. A protein shake and a meal can have similar amounts of protein but serve different purposes and have different compositions. The NNR 2023 chapter on protein provides background on the subject; it does not endorse a particular brand.

In everyday life: identify what contributes protein in the food you plan. To compare Sport with a protein supplement, see the separate guide to their different purposes.

3. Fat is more than a total figure

Fat provides energy and fatty acids. The type of fat in food also matters. Saturated and unsaturated fatty acids are therefore described separately in dietary advice and nutritional evidence. The words low-fat or high-fat do not describe a food in its entirety.

The NNR 2023 chapter on fat and fatty acids explains why fat quality is part of assessing a diet. Our article gives no individual fat recommendation and does not calculate an optimal balance for you.

In everyday life: read both the ingredients and declaration to understand a product. An oil in the list and a saturated fat figure answer different parts of the question. Compare the same quantity and unit.

4. Carbohydrates, fibre and whole grains need to be distinguished

Carbohydrates is an umbrella term, and different foods contain different types. Fibre is listed separately in the declaration. Whole grain describes how the grain's parts remain in the ingredient; it is not another word for all carbohydrates or for the amount of fibre.

The source and overall composition of the food matter here. Porridge, pulses, fruit and a sweet snack have different compositions even though several provide carbohydrates. Read more in the NNR chapters on carbohydrates and fibre.

In everyday life: look at what the planned food actually consists of. To understand the words in an ingredient list, read it alongside the nutritional declaration, without assuming that a single figure proves the quality of the whole product.

5. Vitamins and minerals make variety relevant

Vitamins and minerals have different functions and occur in different amounts in different foods. A varied diet helps provide several types of nutrients. A percentage for a vitamin describes that vitamin's reference value, not a share of all the body's needs.

1177's general advice on healthy eating habits concerns the overall dietary pattern. A product with added vitamins does not make other foods irrelevant. Specific needs require individual assessment.

In everyday life: make sure the question covers more than one powder, bar or meal. Taste, the ability to eat, access to food and variety over time are also practical considerations.

Where does ComFoo fit in?

ComFoo can be an option for a planned meal. Read the selected flavour's ingredients and mixing instructions, and consider it alongside the rest of your everyday food. Original and Sport have different declarations, and each flavour needs to be checked separately.

This article explains nutritional concepts. It does not assess whether your diet is adequate, recommend a number of ComFoo servings per day or promise effects on illness, weight, immunity or mood. For an actual product comparison, follow the examples in the nutritional declaration guide.

Common questions about everyday nutrition

Do more calories mean more vitamins?

Not automatically. Energy and the amount of a particular nutrient are different information. Compare the content of the actual quantity of food you use.

Do I need to count everything to understand food?

You can start by understanding the terms and looking at how meals work in your everyday life. This guide requires neither calorie logging nor body weight.

Can a general article show what I personally need?

No. It explains concepts and general evidence. Individual questions, special diets or medical needs require tailored advice from healthcare professionals.
