Omega -3: What’s all the hype about?

Omega-3: What’s all the hype about?
by Danielle Van Schaick, R.D.

What are Omega-3 fatty acids and why do we need them in our diet?

• Omega-3 fatty acids are polyunsaturated fat, considered vital for good health.
• They are found in 3 main forms, LNA, EPA & DHA.
• Although LNA can be converted in our bodies to EPA and DHA, that conversion is not very efficient (only about 4% to 10%).

Therefore, we want to be getting more EPA and DHA in our diets.

Health Benefits:

Heart disease
Extensive research suggests that higher intakes of EPA and DHA offers considerable protection against heart disease and reduce the risk of death from a heart attack.

Cancer
Population studies have shown that higher intakes of fish (rich in EPA and DHA) are associated with lower rates of some types of cancer.

Mental health
DHA is the most abundant fatty acid in the grey matter of the brain. Research suggests that increasing daily omega-3 intakes, specifically DHA, may help protect against Alzheimer’s disease and other forms of dementia and mental disorders.

Pregnancy & Lactation
Omega-3 fatty acids, specifically DHA, are vital for the early development of the brain, nerves and visual acuity. It’s very important that pregnant women receive sufficient DHA before and during pregnancy.

Inflammatory disorders
Many studies have found that increasing EPA and DHA intakes improved symptoms in patients with inflammatory conditions like arthritis, psoriasis, asthma, gingivitis, ulcerative colitis and Crohn’s disease.

How much Omega 3’s (EPA/DHA) do we need each day?

Male : 25-49 yrs = 1500; 50-74 yrs = 1300; 50-74 yrs = 1100
Female 25-49 yrs = 1100; 50-74 yrs = 1100; 50-74 yrs = 1100

What foods contain EPA and DHA omega-3?

• EPA and DHA are primarily found in fatty fish such as salmon, tuna, swordfish, mackerel, and sardines.

• Fish oil supplements, Omega-3 enhanced eggs are good alternatives to fish.

• Common plant sources of omega-3 fatty acids provide no EPA or DHA, only LNA.

Fish/Seafood (100g = 3-4oz) : Mackerel 3000mg; Herring 2100mg; Salmon 1600mg; Halibut 400mg
