Omega 3 Fatty Acids

What are omega 3 fatty acids?

Omega 3 fatty acids are a type of fat the body cannot make on its own. They are an essential nutrient, which means they are needed to survive. We get the omega 3 fatty acids we need from the foods we eat.

What are the best sources of omega 3 fatty acids?

Fish are the best food source of omega 3 fatty acids. Some plants also contain omega 3 fatty acids.

What do EPA, DHA and ALA mean?

There are two kinds of omega 3 fatty acids in fish ? eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). The form of omega 3 in plants is called alpha-linolenic (ALA).

How do omega 3 Fatty Acids help improve my health?

  • Reduced risk of cardiovascular disease.
  • Less risk of death if you have cardiovascular disease.
  • Reduced risk of sudden cardiac death caused by an abnormal heart rhythm.
  • Reduced risk of blood clots because omega 3 fatty acids help prevent blood platelets from clumping together.
  • Keeping the lining of the arteries smooth and free of damage that can lead to thick, hard arteries. This helps keep plaque from forming in the arteries.
  • Lowering triglyceride levels by slowing the rate they form in the liver. High levels of triglycerides in the blood increase the risk of heart disease.
  • Less inflammation. Atherosclerosis (hardening of the arteries) is thought to involve your body’s inflammatory response. Omega 3 fatty acids slow production of substances that are released during the inflammatory response.

Fatty Acids may also:

  • Raise levels of high-density lipoprotein (HDL/?good? cholesterol).
  • Lower blood pressure. People who eat fish tend to have lower blood pressure than those who don?t.

How much Omega 3 do I need?

It is recommend that patients who do not have a history of heart disease eat at least 2 servings of fish each week (a total of 6-8 ounces). This should include a variety of fish. Cold-water wild varieties of fish like mackerel, tuna, salmon, sardines and herring contain high amounts of omega 3 fatty acids. See the list above to help choose fish with high levels of omega 3 fatty acids.

Can you have too many omega 3 fatty acids?

Talk to your doctor if you have 3 grams or more of omega 3 fatty acids in your diet each day. High levels of these essential fatty acids can cause bleeding.

Should I be concerned about mercury in fish?

Mercury occurs naturally in the environment and as a result of industrial pollution. It falls from the air and can collect in streams and oceans, where it is converted into methylmercury. Too much methylmercury can be harmful. This is especially true for unborn and young children.

Some fish have higher levels of mercury than others. These include shark, swordfish, tilefish, and King mackerel. Everyone should limit the amounts of these fish in their diet. Women who are pregnant or nursing and young children should not eat these types of fish. Women who are pregnant or nursing can safely eat 12 ounces of other types of fish each week. These include shellfish, canned fish and smaller fish.

Albacore Tuna has more mercury than canned light tuna. Limit the amount of albacore tuna you eat to 6 ounces per week.

What if I?m allergic to fish or don?t want to eat fish?

Fish is the best food source of omega 3 fatty acids, but several plants contain ALA(alpha-linolenic acid). This is not as rich of a source of omega 3 fatty acids, but some studies show that ALA(alpha-linolenic acid) can reduce the risk of cardiovascular disease.

Good sources of ALA (alpha-linolenic acid)are ground or milled flaxseeds, flaxseed oil, chia seeds, walnuts, soy foods and canola oil. Another source of ALA is algae or algae oil, which is broken down to DHA. Many foods that are fortified with omega use algae oil. These are excellent options for vegetarians that do not eat fish.

There are currently no serving size recommendations for ALA-rich foods. But, adding these foods to your diet regularly may help your heart health.
