Eating throughout the day is extremely important, because missing meals leads to low blood sugar, and this lowers our mood, makes us irritable and fatigued.

Selecting less high sugar foods is also important because these foods produce energy which dies off quickly, leaving you fatigued. Try more whole grains, fruits and vegetables, which will reduce mood swings. Also, these foods contain thiamin, a vitamin associated with mood control.

In addition, include a protein at each meal. Tryptophan is an amino acid found in proteins that effects mood. To make sure your brain receives a constant flow, eat one portion of protein at each meal.

A wide variety of foods is important to make sure you get all nutrients. Include red meat and fish, because they contain high levels of Vitamin B12, which is associated with mood, however, if you are a vegetarian, try fortified soy mince or yeast extract.

Studies show that omega 3 oils reduce symptoms of depression. Omega 3 oils can be found in oily fishes, but if you are a vegetarian, try a purified omega 3 supplement.

Drink enough water, because dehydration leads to irritability, loss of concentration and reduced efficiency in mental tasks. Also, avoid too much caffeine, because in large amounts it increases anxiety, depression, and sleep problems.

Lastly, it is vital to exercise. Take 30 minutes at least three days a week to walk outside. Exercise boosts endorphins which produce feelings of euphoria, and being outside in the sunshine has also been shown to enhance mood.
