Increasing the amount of omega-3 fats in our diet and decreasing the amount of omega-6 is beneficial in reducing your risk for heart disease. Most American’s consume a high omega-6 diet, with omega 3 being a common deficiency. Omega 3 deficiencies and the imbalance between omega 3 and omega 6 intakes have been linked with serious conditions, including heart attacks. Successfully maintaining a ratio of 4:1 to 1:1 omega 6 to omega 3 will help lower cholesterol levels and control high blood pressure.
Now, how much omega 3 do you need to add?
This is under debate and more research is being done. Right now the range experts recommend is from 500-2000 mg/day. Here are the current American Heart Association (AHA) recommendations.
The AHA recommends that individuals without heart disease eat a variety of fish twice a week, use heart healthy oils (flaxseed, canola, soybean oils), and consume flaxseed and walnuts.
For individuals with heart disease, the AHA recommends 1 g of EPA (eicosapentanoic acid) + DHA (docosahexaenoic acid) daily, preferably from fatty fish.
The AHA recommends 2 to 4 g of EPA + DHA daily, under physician’s care only, for individuals that need to lower triglycerides. High doses, > 3 grams/day, can result in excessive bleeding. (Do not self medicate! Talk to your doctor before supplementing greater than 2 grams.)
Omega 3 Content of Different Foods
Now, there’s a reason I included details on amounts of ALA, DHA and EPA for each omega 3 source. Right now, DHA and EPA have a greater link with lower cholesterol levels, lower triglycerides, and higher HDL levels than ALA. The body is able to convert ALA to EPA and DHA, but the conversion rate is low; therefore, it is best to include high DHA and EPA sources in your eating plan.
Eight steps to lower your cholesterol
My recommendation:
As a preventive measure and to promote lower cholesterol and blood pressure control, I recommend eating fish twice a week, select a supplement that will provide you at least 1000 mg of omega 3 fatty acids daily (choose a good source of DHA and EPA), and use ground flaxseed when appropriate in your meal preparation.
All the best,
