Do you know of anybody who is easily agitated, hostile, or most of the time angry?
Have you been around someone who is on a diet, especially those following fad diets or people who are on crash diets? Or maybe you’ve been with friends and family who missed eating meals …
If you answered yes to these questions, read on as you’ll be surprised. If you answered no on the other hand, try to be with someone who has missed breakfast, lunch or dinner, surely it’ll not take long before you finally say “now I understand”.
Now here’s interesting information for you.
According to a recent study, people who are hostile, people who are easily angered are most likely people with very low serotonin levels, and there is a big chance that they are like this because they missed eating a good full meal.
According to the study, people who do not eat are more prone to violence or aggression. This is because when serotonin levels are low, and this happens when a person has not eaten, controlling emotional responses to anger becomes more difficult.
So this explains why people who are on crash diets are most of the time irritable and are almost always “grumpy”; it’s the low serotonin in their system that’s causing it.
The study was done by the Cambridge University of Britain and was published in the journal Biological Psychiatry.
In the study, the diets of the volunteers were changed. Two appointed days were chosen and were given the names Serotonin Depletion Day and Placebo Day.
On the Serotonin Depletion Day, the volunteers were given a combination of amino acids which lacked tryptophan, the building block for serotonin. This had an effect similar to what happens when a person does not eat.
On the placebo day, the volunteers were given the same mixture but with a standard amount of tryptophan. This had an effect similar to what happens when a person eats.
The volunteers were then made to view images depicting facial expressions such as anger, sadness, and neutral expressions. While this was going on, the brains of the volunteers were scanned using functional magnetic resonance imaging or fMRI. Through this exercise the researchers were able to measure how different brain regions responded to and communicated with each other.
The results showed that for volunteers with low brain serotonin, which happens when a person has not eaten, communication between the amygdala and the frontal lobes were weak. The opposite holds true when the volunteers’ serotonin levels were normal.
So to be able to control your emotional response to anger, eat regularly and healthily. Eating regularly and eating healthily will ensure a good level of serotonin, the key to controlling emotional responses to anger.
