Omega 3’s are immportant to the development of the brain and visual functions in infants and are also associated with retaining these functions through life.
In one study men who ate atleast 2 portions of fish a week were 45% less likely to have MACULAR DEGENERATION which is the biggest cause of blindness in older people.
Omega 3’s are also ANTI-INFLAMATORY, thus helping to balance the OMEGA 3’S with the OMEGA 6’S a balance of 1 to 2 is considered a good balance another study followed 80,000 healthy women for 14years and found that those with the highest levels of healthy D.H.A and E.P.A had a significantly lower risk of heart and stroke disease.
The levels of D.H.A and E.P.A for men and women as follows:-
Men 610mg per day
Women 430mg per day
To give some idea of what food is needed to get this.
A 150g portion of salmon (try to buy Atlantic or Alaskan wild salmon) gives 4700mg of omega 3’s which is all that is required for 1 week.
However 2 portions of oily fish a week is recommended
D.H.A Docosahaenoic Acid, A 22 carbon atom (long chain) with 6 double bonds is an Omega 3 Essential Fatty Acid which helps with High Blood Pressure (by reducing fat in the blood), and inflamation in the body.
