  1. Happy Eating Basel seminar December 2016 Andrew Oswald (Warwick) Joint work with Redzo Mujcic (Vienna)

  2. STEP 1

  3. Max Planck (1897/1903): “it is impossible to construct an engine which will … produce energy… from nothing.”

  4. “A new scientific truth does not triumph by convincing its opponents …

  5. “A new scientific truth does not triumph by convincing its opponents … but rather because its opponents eventually die…”

  6. A now-large literature

  7. Say we approach the topic in a different way than is usual.

  8. Let’s think about biological fundamentals, and the first law of thermodynamics.

  9. As humans, we run on a kind of fuel:

  10. As humans, we run on a kind of fuel: food

  11. STEP 2

  12. STEP 2

  13. Now consider the quality of the fuel

  14. Now consider the quality of the fuel

  15. Here’s the system that keeps us going.

  16. The gastro-intestinal tract (GI Tract)

  17. If you want to know more http://www.gutfoundation.com.au//GITract

  18. And forget the AER...........

  19. And forget the AER...why not publish in GUT(Impact Factor = 14.9)

  20. And forget the AER...why not publish in GUT(Impact Factor = 14.9)

  21. Why would a social scientist care?

  22. The GI Tract system stores 90% of something important to us.

  23. The GI Tract system stores 90% of something important to us. 5-hydroxytryptamine

  24. The GI Tract system stores 90% of something important to us. 5-hydroxytryptamine...which is

  25. The neurotransmitter serotonin

  26. Your GI Tract stores 90% of your serotonin.

  27. There is a large literature on links between serotonin and mental well-being (or ill-being).

  28. FOLATE-DEFICIENCY AND DECREASED BRAIN 5-HYDROXYTRYPTAMINE SYNTHESIS IN MAN AND RAT By: BOTEZ, MI; YOUNG, SN; BACHEVALIER, J; et al. NATURE  Volume: 278   Issue: 5700   Pages: 182-183   Published: 1979

  29. Moreover

  30. Moreover A whole class of antidepressants works by promoting higher levels of serotonin. Selective serotonin reuptake inhibitors (SSRIs)

  31. There are lots of interesting papers to read on this topic.

  32. How to increase serotonin in the human brain without drugs By: Young, Simon N. JOURNAL OF PSYCHIATRY & NEUROSCIENCE  Volume: 32   Issue: 6   Pages: 394-399   Published: NOV 2007

  33. Influence of clinical factors, diet, and drugs on the human upper gastrointestinal glutathione system By: Hoensch, H; Morgenstern, I; Petereit, G; et al. GUT  Volume: 50   Issue: 2   Pages: 235-240   Published: FEB 2002

  34. There is known to be a cross-sectional link between folate and mental health

  35. There is known to be a cross-sectional link between folate and mental health Serum Folate, Vitamin B-12, and Homocysteine and Their Association With Depressive Symptoms Among U.S. Adults By: Beydoun, May A.; Shroff, Monal R.; Beydoun, Hind A.; et al. PSYCHOSOMATIC MEDICINE  Volume: 72   Issue: 9   Pages: 862-873   Published: NOV-DEC 2010

  36. However, nearly all RCTs giving people folate in pills (compared to a placebo) have failed to find an effect.

  37. B vitamins in RCTs have been somewhat more successful Effects of Vitamin and Mineral Supplementation on Stress, Mild Psychiatric Symptoms, and Mood in Nonclinical Samples: A Meta-Analysis By: Long, Sara-Jayne; Benton, David PSYCHOSOMATIC MEDICINE  Volume: 75   Issue: 2   Pages: 144-153   Published: FEB-MAR 2013

  38. The main idea in this paper

  39. The main idea in this paper There may be an important link between food types and later happiness and mental well-being.

  40. The main idea in this paper There may be an important link between food types and later happiness and mental well-being.

  41. There is a prior cross-sectional literature on the wellbeing pattern with Fruit+Veg portions. Plus a tiny number of RCTs.

  42. Also a recent diary study Many apples a day keep the blues away - Daily experiences of negative and positive affect and food consumption in young adults By: White, Bonnie A.; Horwath, Caroline C.; Conner, Tamlin S. BRITISH JOURNAL OF HEALTH PSYCHOLOGY  Volume: 18   Issue: 4   Pages: 782-798   Published: NOV 2013

  43. Plus I hugely recommend: Rooney C, McKinley MC, Woodside JV (2013). The potential role of fruit and vegetables in aspects of psychological well-being: A review of the literature and future directions. Proceedings of the Nutrition Society 72, 420-432.

  44. Our paper uses Australian data:

  45. The initial data in our study come from Waves 7 and 9 (years 2007 and 2009) of the Household, Income and Labour Dynamics in Australia (HILDA) Survey. Sample size = 12,000 people approx.

  46. We then replicated it on recent 2013 data.
