 A study on healthy and sustainable eating habits

Eating habits impact both our health and the environment. A diet high in sugar, salt, and animal fats but low in whole grains, vegetables, and fish can increase the risk of diseases such as cardiovascular disease and type 2 diabetes while also negatively affecting the climate.

SWITCH is a research study investigating how different types of support can help people adopt healthier and more sustainable eating habits. The study is part of a larger EU-funded project and is conducted by Chalmers University of Technology, the University of Gothenburg, and Sahlgrenska University Hospital.

How does the study work?

The study lasts 12 weeks and includes 300 participants from different areas in Gothenburg. Participants are randomly assigned to one of three groups, each receiving a different level of support:

  • Full support: Dietary counseling, behavioral support, and access to certain foods.
  • Moderate support: Dietary counseling and behavioral support, but no food provided.
  • Basic support: Only dietary counseling.

The goal is to increase the consumption of healthy and sustainable foods, such as whole grains, legumes, fruits, and sustainable seafood products.

What does the study measure?

The study examines how diet affects health and the environment by measuring:

  • Blood pressure, blood sugar, and blood lipids.
  • Nutritional status (vitamins, minerals, fatty acids).
  • Inflammation in the body.
  • Environmental impact of dietary changes.

Data collection and analysis

All participants attend three clinical visits: before the study starts, at week 7, and at week 13. At these visits, blood samples and other health measurements are taken. Participants also record their diet and complete questionnaires about their eating habits, physical activity, and lifestyle.

Who is conducting the study?

The study is conducted by Chalmers University of Technology, the University of Gothenburg, and Sahlgrenska University Hospital. The clinical visits take place at the Center for Lifestyle Intervention at Sahlgrenska University Hospital/Östra Hospital in Gothenburg.
The study is approved by the Swedish Ethical Review Authority.
