Sustainable nutrition

Defining healthy and sustainable diets

The world’s food system faces a great balancing act. By 2050 it must feed around 10 billion people more sustainably without increasing the agricultural land area, using fewer natural resources, and emitting fewer greenhouse gases. In addition, diets should be healthier and meet human nutritional needs. Diets should prevent malnutrition and non-communicable diseases like obesity and cardiovascular disease.

The research area of sustainable nutrition attempts to provide answers on how to meet these challenges.

Healthy and sustainable diets

Businesses, governments, and civil society organizations are all looking for ways to make our food healthier and more sustainable. Blonk can help your organization identify the available options to achieve this. The answer ultimately lies in finding the right balance between food sustainability and health value. We use optimization techniques to help understand how to improve diets with minimum changes to eating habits.

Optimeal 

Grasp the complete picture of healthy and sustainable diets


Defining healthy and sustainable food patterns is complex and should be based on a systematic investigation and sound data. We developed our Optimeal tool to help you understand the complete picture of healthy and sustainable nutrition. Optimeal facilitates the exploration of many options, identifies new opportunities, and helps elevate the level of discussions regarding the optimization of diets for health value and sustainability.

Optimeal for companies producing foods and beverages

The main challenge for companies producing foods and beverages is to become 'future-proof' regarding health, environmental, and other sustainability concerns. Future-proof foods and beverages properly balance their nutritional value and environmental impact. This concept is called the Sustainability Nutrition Balance (SNB), which identifies whether a product or product group fits into a healthy and sustainable diet. The SNB-score can be determined in several steps, offering directions toward developing products that meet nutritional and sustainability requirements. With the help of Optimeal, we can assign SNB-scores to products or product portfolios.

A dietary pattern that is healthy for both Belgians and the planet

WWF launched the European Eat4Change project to make young Europeans aware of ways to develop and adopt a healthier and more sustainable diet. Our current food system has a substantial environmental impact. With Eat4Change, WWF wants to make food production more sustainable, combat biodiversity loss and tackle the climate crisis. As part of this European project, on behalf of WWF Belgium, we analyzed which products fit into a sustainable and healthy diet for a family of four. We did so using our Optimeal software tool. The results also show that a sustainable and healthy diet is cheaper than the average Belgian's current dietary pattern.
