Fikk veldig raskt svar, ble postivt overrasket over det:

Ved Massachusetts Institute of Technology (http://web.mit.edu/) I USA er det gjort mye forskning på dette feltet, særlig av Judith og Richard Wurtman.
Her linker jeg opp er par artikler der forskningen er omtalt:

Her er en link til det meste av forskningen paret Wurtman og deres kolleger har gjort på humør og kosthold: http://wurtmanlab.mit.edu/publications.php#sero

Under finner du utdrag fra en artikkel som oppsummerer forskningen.
Low-carb dieters are susceptible to mood swings, according to MIT researchers. The issue involves serotonin, the "feel good" brain chemical that elevates mood, suppresses appetite and acts as a natural tranquilizer.
In news released earlier this year, the Massachusetts Institute of Technology Clinical Research Center reported that a lack of dietary carbohydrates causes the brain to stop regulating serotonin. Researchers discovered that serotonin is naturally produced only after consumption of carbohydrates in the form of sweets and starches.
In the 1970's, MIT professor Richard Wurtman and colleagues first showed that eating carbohydrates raises brain serotonin levels. Since then, additional studies at MIT, including those by Dr. Judith J. Wurtman, have explored the relationship between carbohydrates in the brain and their connection to mood and weight loss. Dr. Wurtman states in a February MIT press release that "When serotonin is made and becomes active in your brain, its effect on your appetite is to make you feel full before your stomach is stuffed and stretched." The researchers explain that people may still feel hungry after eating a large steak-their stomachs may be full but their brains may not be producing enough serotonin to shut off their appetites.
It's not unusual for people who are changing their eating patterns or embarking on any kind of diet to experience episodes of irritability. However, according to Psychology Today, many who are trying testing low-carbohydrate regimens are reporting unusually high feelings of anger, tension and depression. Dr. Wurtman claims that that it's a very well documented response-she calls it the "Atkins attitude". Dieters who have eliminated or reduced dietary carbohydrates may find that their low mood is combined with irritability if the diet is heavy on protein, and/or combined with a lack of energy if the diet is heavy on saturated fats.
Are certain people more susceptible to low mood? According to Wurtman, some people are "carbohydrate cravers" -- they tend to experience a change in their mood, usually in the late afternoon or early evening -- and they need to eat a certain amount of carbohydrates to keep their moods steady. And although both men and women can experience low mood when cutting carbs, women are more likely to feel the effects because they are known to have typically lower levels of serotonin in their brains than men.
Because of her research, Wurtman believes that low-carb diets may be dangerous for individuals who are already struggling with depression or bipolar disorder. In an Oxford study involving women, researchers did find that those who had a predisposition to mood disorders exhibited a measurable drop in mood when following a low-carb regimen, but reported that other subjects on the diet did not seem to be impacted.

Skal lese litt på dette etterpå, og håper på litt kommentarer fra dere som kan mer om dette enn meg
