Most European countries have developed food-based dietary guidelines (FBDGs), or, simply, healthy food recommendations, for their populations. They provide “advice on foods, food groups and dietary patterns to provide the required nutrients to the general public to promote overall health and prevent chronic diseases”. Some countries provide a graphic representation, such as a food pyramid or a plate, to illustrate and sum-up the advice. As the food pyramid is one of the most common and hence most familiar graphic representations, it is used as an example throughout this article. To make it simpler, healthy food guides are used as an umbrella term for FBDGs. 

Old and new food pyramids

The original food pyramid was created in Sweden in 1974. Other food advice had been presented earlier to the public, both in Sweden and elsewhere, but often as text or as a food circle. This first pyramid, which both grouped different types of food and showed the relative proportions in which they should be consumed, gained national and international attention. It was praised as easily understandable by everyone, including people with a low literacy.

Today, 90 countries worldwide have developed food-based dietary guidelines, or healthy food guides, for their populations. Some messages are nearly universal, such as consuming a variety of foods (including ample amounts of fruits and vegetables and water as the beverage of choice) and limiting intake of sugar, fat and salt. There are, however, some variations from country to country, as the guidelines are adapted to local situations. For example, in the Middle Eastern countries, legumes (like chickpeas and lentils) are commonly given in a food group of their own as they are a culturally important part of the diet in this region. Some Mediterranean countries, such as Croatia, Cyprus, Greece and Spain, highlight the importance of choosing olive oil in the diet. 

Building a balanced diet

Food pyramids are developed to help people build a balanced and varied diet by following the food groups (levels of the pyramid) and consuming them in the right proportions (the size of the levels, from bottom to top). In practice, a balanced diet means that we should eat a variety of foods, in different proportions, and in general avoid leaving out entire food groups, as each food group provides fuel and nutrients required for optimal health. There are some differences in how foods are grouped from country to country.

The main food groups

Most dietary guidelines group foods into different categories, such as fruits and vegetables, grains and starches, protein rich foods, dairy foods, fats and oils, and foods to be limited. Each food group will provide different proportions of carbohydrates, fats and proteins. These so-called macronutrients are the main building blocks of our diet. Macronutrients provide energy and allow for normal growth and development. Different food groups contain varying amounts of macronutrients, but usually one or two dominate. For example, potatoes contain mostly carbohydrates, meat contains both proteins and fat, and beans contain carbohydrates and proteins. This composition also determines which food group food will belong to. In addition to the macronutrients, each food group will provide different proportions of vitamins and minerals, also called micronutrients, which are required in much smaller amounts and which support the proper functioning of our bodies. By consuming foods from all levels in the pyramid, we get all the important nutrients our bodies need. For example, dairy products can help provide calcium to support bone health, and consuming enough fruits and vegetables will supply vitamin C to support a healthy immune system. Excluding certain food groups from the diet increases the risk of getting too little or too much of some macronutrients, but also too little of the wide range of vitamins and minerals essential for healthy living. Additionally, it is crucial to think about portion sizes to avoid over- or undereating.

Some people have allergies or intolerances that necessitate exclusion of some products from the diet, whilst others (like vegans and vegetarians) choose to leave out certain products. In these cases, people should seek out alternatives that provide the same nutrients. Examples include fortified soya or nut drinks in place of dairy milk.

Examples of balanced meals

So, where to start? Look up the dietary guidelines of your country and have them in mind when planning your meals and grocery shopping... portion sizes and nutrient needs will vary depending on age, gender, activity level, pregnancy or breastfeeding, and health status.

Food pyramid for kids

Existing food pyramids represent healthy diets for populations in general, sometimes with adjustments for people in specific conditions, life-stages or circumstances (e.g. pregnant and breast-feeding women, or elderly). Children have slightly different nutritional needs to adults, but healthy food guides usually apply for children from 2 years of age and older. Still, portion sizes need to be adjusted for children, but always keeping in mind their activity level and growth. Generally, children are advised to be more physically active than adults.

Food pyramid for vegetarians and vegans

Similarly to healthy food guides for children, there are no official guides specifically for people who choose to eat vegetarian or vegan. However, more plant-based diets are gaining popularity, and balanced diets can be adjusted accordingly. Careful planning might be required to ensure the diet provides the right nutrition. For example, vegans and some vegetarians need to think carefully about getting enough vitamin D, vitamin B12, calcium, iron, zinc and omega-3 fatty acids, in addition to high quality protein. It is also important to know that iron from plant-based foods is not as well absorbed as (haem) iron from animal-based foods. While many plant-based foods such as tofu, lentils and chickpeas can be rich in iron, this iron is not as well absorbed as iron from animal-based foods. One way to improve the absorption of iron from these foods is to consume them with foods rich in vitamin C, such as orange juice, which can help improve iron absorption from plant-based sources.

For those on a vegan diet, it can be very difficult to get enough vitamin B12 from dietary sources as this vitamin is only naturally present in animal-based foods. It can also be found in fortified foods and yeast extracts, but these sources may not always be available. For this reason, it may be necessary to take vitamin B12 supplements to ensure an adequate intake.

Healthy food guides for people with diabetes

In general, people with type 1 and type 2 diabetes are also advised to follow the dietary guidelines for a healthy and balanced diet. As for the rest of the population, this means that starchy vegetables, wholegrain products and fruit should be the main sources of carbohydrates, and the consumption of added sugar, saturated fat and salt should be limited. In addition to medication, spreading carbohydrate intakes across the day and staying active may help keep blood sugar stable. 16,17 For people with diabetes it is recommended to consult a registered dietitian or general practitioner before making significant dietary changes.


Food pyramids and healthy eating guidelines are made to represent a healthy diet for the population in general. We should adjust them by choosing the right amounts of preferred foods within each food group to fit our individual health, lifestyle, life-stage and preferences. Aiming for balanced meals and a variation of foods within each level of the pyramid is beneficial for optimal health. Physical activity is equally important for living a balanced and healthy life.
