Over the last few years, a great deal of information has been shared about the sustainability of our food. We are often encouraged to consume more plant-based products and eat less animal-based products. Such a rule is too general and simplistic. In the case of plant-based products, differences in nutritional value and environmental impact can be significant. The same goes for animal-based products.

More insights into sustainable diets

The Optimeal® calculations provide more and better insights into a sustainable diet. By entering a change in your diet, the Optimeal® Tool can provide healthy alternatives and show what effect this will have on CO2 emissions and the price of your groceries.

This video explains how the Optimeal® Tool works and how dietary changes can affect CO2 emissions and your grocery bill. Watch it here:

Dairy as part of a sustainable diet

For any change in your diet, the Optimeal® Tool will provide an alternative diet that contains the same amount of nutrients. What does the Optimeal® Tool tell us about dairy? If you use less dairy Optimeal® will provide an alternative diet that contains the same amount of nutrients. The Optimeal® Tool then calculates the effect on CO2 emissions and how expensive the alternative diet is. If you take dairy out of your diet, you will need to eat considerably more vegetables, fish, beans and pulses to get the same amount of nutrients. This is why consuming less dairy has only a limited impact on CO2 emissions. Conclusion: dairy is part of a healthy and sustainable diet because it’s an environmentally-efficient source of nutrients.
