Effect of sub chronic tryptophan supplementation on stress-induced cortisol and appetite in subjects differing in 5-HTTLPR genotype and trait neuroticism.

Psychoneuroendocrinology - 1 Jul 2014

Capello Aimée E M, Markus C Rob

Abstract excerpt

Stress or negative effect often increases preference for, and intake of, palatable snack foods and this may be influenced by cognitive and genetic factors related to stress and 5-HT vulnerability. The short (S) compared to the long (L) allele of the 5-HT transporter linked polymorphic region (5-HTTLPR) has been associated (i) with decreased 5-HT transporter function and availability and hence, with 5-HT...
