Fish

Vitamin D is produced by the body when it is exposed to sunlight and a deficiency of it over the winter months is thought to be one of the causes of SAD (seasonal affective disorder). Found in especially high levels in fish, vitamin D might help relieve mood disorders by increasing the amount of serotonin — one of the neurotransmitters responsible for the “feel good factor” — in the brain. 

Eggs

The omega-3 fatty acids found in eggs are natural mood lifters and may even help alleviate depression. Eggs are also full of phospholipids, which allow nutrients to pass into the brain more effectively, thus helping to keep your memory and brain function sharp. Oily fish are another great source of omega 3.

Water

Keeping your body and brain hydrated is probably one of the most important things that you can do for your health. Two thirds of the body is made up of water, so keeping a regular intake allows all bodily functions to occur correctly.

Chocolate

You probably don’t need us to tell you chocolate can make you feel better; it’s especially good for you if you stick to good quality dark chocolate with a high cocoa content and steer clear of sugar-rich, inferior products.

Oranges

Most people link oranges to vitamin C, but they are also high in folate. Folate is thought to be important to enhancing moods and, like vitamin B12, is believed to play a role in the creation of serotonin — the brain’s happy chemical!

Nuts and seeds

Most nuts contain selenium, which is thought to help prevent depression and be vital for good mental health.
