Dr Andrew Reynolds is a research fellow interested in lifestyle risk factors such as what we eat and when we move, and health outcomes. Andrew has a particular interest in fibre-containing foods such as whole grains, vegetables, legumes, and whole fruit, or dietary fats and their sources. He conducts randomised controlled trials to generate new knowledge or systematic reviews and meta analyses to synthesise current knowledge. He is available to supervise keen students undertaking any degree type.

His current research includes:

  • Wholegrain intakes and the effects of food processing
  • Legume intakes for improved cardiometabolic risk management
  • Evidence-based guideline development
  • Cognition during carbohydrate digestion
  • Dietary fats and premature mortality
  • Dietary patterns which promote individual and planetary health
  • Barriers and enablers to undertaking regular physical activity
  • Physical activity guidelines for diabetes management
