For those who don't know, oxytocin is a hormone released during those bonding moments in life - think sex, childbirth and breastfeeding.
The study revealed after a dose of oxytocin (via nasal spray, for example) participants with anorexia were less likely to focus on the negative images of food and fat parts of the body.
Treasure's colleague, Prof Youl-Ri Kim of Inje University in South Korea, told the BBC: "Our research shows that oxytocin reduces patients' unconscious tendencies to focus on food, body shape, and negative emotions such as disgust."
The eating disorder, anorexia nervosa, has no definitive cure - but any treatment seen to be making any kind of difference is a big deal.
