In the book Digestive Health with Real Food (page 45), it writes …

“People with fructose malabsorption don’t have enough tryptophan, even though they eat enough of it, and therefore can’t produce enough serotonin to feel good … in their study, reducing dietary fructose resulted in a 65-percent improvement in depression score in only four weeks.”
