Depression seems to have increased continuously since the beginning of the last century and is now one of the most commonly diagnosed conditions in the world.
Part of the blame lies with Western eating habits in which the anti-inflammatory and beneficial omega 3 fats found in oily fish have been replaced by harmful omega 6 fatty acids in cereal grain oils like sunflower and canola.
A recent review of many studies on depression revealed that either a significant decrease of polyunsaturated omega 3 fats or an increase in omega 6 fats was the common factor.
A healthy ratio of omega 6 to 3 is around 1:1 or even 3:1 but today, many people have a ratio of 25:1 or even much higher.
One of the omega 3 studies regarding depression discovered that severely depressed patients had very low levels of a serotonin metabolite called 5-HIAA. It is now known that omega fatty acid levels in your body predict that 5-HIAA levels and in turn, help to increase your serotonin levels too.
A large study was carried out in Finland which found that people with depression who took 2g of fish oil a day for 6 months experienced a significant easing in the symptoms and further, were less prone to having suicidal tendencies.
Other studies have found a correlation between high incidences of depression in those countries with low fish consumption.
Their secret is the potent omega 3 fatty acids known as EPA and DHA. Recent studies have revealed that the DHA fats are responsible for many health benefits and especially for your brain.
Over 97% of the omega 3 fats in your brain are DHA and they account for around half of the total fats. These need constant replenishing and this needs to come from your diet as your body cannot make them.
You need oils rich in DHA to get the maximum from them and they also need to be as pure as possible. Molecularly distilled oils have all the toxins removed to leave them safe and pure.
The only thing with fish oil is that it takes time to work but offers many other wonderful health benefits, unlike the addictive and potentially harmful pharmaceutical meds.
You should notice significant mood improvements within 1-2 months and around 6 months is needed for the full effects to be realized.
Taking fish oil for depression allows you to gradually and naturally lift your mood while experiencing many other health benefits too.
