Dementia and Omega-3’s
A host of studies have looked at the relationship between omega-3 fats and brain function and found that Omega 3’s provide lots of benefits for brain health.
One of the crucial ways to ward off dementia, is balancing the ratio of omega-6 and omega-3 fats in your daily diet. Both are essential fatty acids (EFAs), meaning that we must obtain them from our diet (our bodies can’t manufacture them), however, the typical North American consumes far too many omega-6 fats and not enough omega-3 fats.
The ideal ratio of omega-6 to omega-3 fats should be about 1:1. Most people’s intake ratio of omega-6 to omega-3 averages from 20:1 to 50:1! The primary sources of omega-6’s are corn, soy, canola, safflower and sunflower oil and meat from animals fed these products. Try to reduce or limit your intake of these oils and aim for more naturally raised, grass fed meat.
Your best way to increase omega-3’s in your diet is fish oil or krill oil. Eating sustainable, low pollutant fish 2-3 times per week (www.kidsafeseafood.org is a good resource for this) and/or taking fish/krill oil can help restore the natural balance of omega 3:omega 6.
