This fact sheet offers generic advice on depression but everyone is different. It is therefore beneficial to have a personal health and nutrition assessment to get specific advice that takes account of al your health issues. Include:

snapper contain the highest levels tryptophan which wil help lift your mood.

Exclude:

• sugary foods, including honey and syrup

levels of these in your body can cause (or add to) stress and anxiety.
• wheat products - wheat contains gluten which has been linked to depression and anxiety

• Omega-3 (There are 2 sub-types of omega-3; DHA (docosahexaenoic acid) and EPA
(eicosapentaenoic acid). Choose a brand that provides at least 600 mg of each)

The science bit!
Serotonin (the feel good brain chemical) is produced and absorbed in the gut. If your digestive system is impaired and you have too many toxins in your system, you wil not be absorbing the right levels of serotonin (or any other nutrients). It is therefore crucial to stop smoking and eating junk food to reduce the number of toxins in your system.
Our bodies only produce half of the amino acids we require. The rest, cal ed essential amino acids, come from food or supplements. One of the essential amino acids is methionine, which breaks down in the liver to produce a sub-amino acid cal ed S-adenosylmethionine (SAM-e (pronounced sammy) for short!). SAM-e is known to raise levels of the brain chemicals dopamine, norepinephrine and serotonin. Low levels of these chemicals are associated with depression. Natural food sources of methionine include fish, meat, milk, nuts and eggs.
