Omega 3’s


Why They’re a Good Fat

Not all fats are unhealthy. Omega-3 fatty acids are one of the “good” types of fat. They may help lower the risk of heart disease, depression, dementia, and arthritis. Your body can’t make them. You have to eat them or take supplements

Know the 3 Types of Omega-3s

Omega-3 fatty acids come in more than one form.

The types found in fish, called DHA and EPA, seem to have the strongest health benefits.

Another form known as ALA is found in vegetable oils, flaxseed, walnuts, and dark leafy vegetables such as spinach.

The body is able to change a small amount of ALA into EPA and DHA.

How Omega-3s Fight Disease

Omega-3 fatty acids help your heart in several ways. They curb inflammation in the blood vessels (and the rest of your body). They may help to slow plaque buildup inside the blood vessels.  

If You Have Heart Disease

The American Heart Association recommends 1 gram a day of EPA plus DHA for people with heart disease.

Eating oily fish is best  (Salmon, mackerel, sardines, trout and herring) but your doctor might recommend a fish oil capsule.

Some studies show fewer heart attacks and fewer heart disease deaths among heart attack survivors who boosted their levels of omega-3.

Omega-3 foods and supplements may curb plaque buildup inside blood vessels, helping with blood flow.

So they may help prevent stroke caused by clots or a blocked artery.

********** But at high doses, omega-3 supplements might make bleeding-related stroke more likely; so check with your doctor.

Helping Your Heart’s Rhythm

Studies have shown that omega-3 fatty acids seem to have a stabilizing effect on the heart. They can lower heart rate and help prevent arrhythmias (abnormal heart rhythms).

Several common sources of omega-3 fatty acids are fish, walnuts, broccoli, and edamame (green soybeans that are often steamed and served in the pod).

Cutting Triglycerides

Omega-3s DHA and EPA can lower your triglycerides, a blood fat that’s linked to heart disease.

Be sure to talk with your doctor before taking omega-3 supplements, because some types can make your “bad” cholesterol worse.

Lowering High Blood Pressure

Omega-3s may help lower blood pressure. Avoid salty fish, such as smoked salmon. If you have high blood pressure, limiting salt is probably one of the things your doctor has recommended.

Depression and Brain Benefits?

Depression is rarer in countries where people eat a lot of omega-3s in their typical diet. But omega-3s aren’t a treatment for depression. If you’re depressed, talk with your doctor about what might help you feel better.
Try Tuna

Tuna can be a good source of omega-3. Albacore tuna (often labeled “white”) has more omega-3 than canned light tuna, but it also has a higher concentration of mercury contamination. The amount of omega-3 in a fresh tuna steak varies, depending on the species

Avoid Contaminated Fish

Due to its important nutrients for growth and development, and low intakes the FDA changed from limiting fish consumption to encouraging it. For most people, mercury in fish is not a health concern. But the FDA has this advice for young children and for women who plan on becoming pregnant, are pregnant, or are nursing:

  • Eat 8-12 ounces of fish per week, 2-3 times a week. Provide kids age-appropriate portion sizes. Limit albacore tuna to 6 ounces per week.
  • Choose fish lower in mercury, such as salmon, shrimp, pollock, tuna (light canned), tilapia, catfish, and cod.
  • Avoid shark, swordfish, king mackerel, and tilefish, and limit albacore tuna to no more than 6 ounces a week.

Omega-3 Supplements

If you don’t like fish, you can get omega-3 from supplements. One gram per day is recommended for people with heart disease, but ask your doctor before starting. High doses can interfere with some medicines or increase risk of bleeding.

You may notice a fishy taste and fish burps with some supplements.******* Try taking supplements at night- this worked for me!

Vegetarian Sources of Omega-3s

If you don’t eat fish or fish oil, you can get a dose of DHA from algae supplements. Algae that is commercially grown is generally considered safe, though blue-green algae in the wild can contain toxins. Vegetarians also can get the ALA version of omega-3 from foods such as canola oil, flaxseed, walnuts, broccoli, and spinach — or products fortified with omega-3s.

Avoid the Omega-3 Hype

Many food products now boast that they have added omega-3 to support various aspects of your health. But be aware that the amount of omega-3 they contain may be minimal. They may contain the ALA form of omega-3, which hasn’t yet shown the same health benefits as EPA and DHA. For a measured dose of omega-3, taking fish oil supplements may be more reliable.
