For many years, omega-3s have been reported to be heart healthy. And thanks to the Mayo Clinic’s groundbreaking comprehensive analysis of the role of omega-3 dosage on cardiovascular prevention completed this year, those benefits have been quantified.
The study reviewed 40 separate clinical trials involving the consumption of the omega-3s eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). The result is that both EPA and DHA omega-3 intake reduced the risk of myocardial infarction (heart attacks) and coronary artery disease.
But in the United States, cardiovascular disease continues to be the leading cause of death. In 2018 there were 30.3 million adults diagnosed with heart disease which include several types of heart conditions.
So, obviously, we’re not doing enough as far as prevention, even though omega-3s seem to offer us a pretty solid route.
What if you or someone you love has a heart attack? Well, my best friend did two years ago and survived this life-changing event. She was one of the lucky ones because on average someone dies of cardiovascular disease every 37 seconds in the U.S.
New research involving omega-3s shows that even in the event of a heart attack, they can help you come out better…
Vitamin D blood levels during a heart attack
A research team from the Germans Trias, Research Institute (IGTP), and the Hospital del Mar Medical Research Institute (IMIM), recently found that a diet full of foods rich in omega-3 fatty acids, strengthens heart membranes and the prognosis in the event of a heart attack.
How do they know?
They saw firsthand that having high omega-3 blood levels in patients who were admitted to the hospital at the time of a heart attack was associated with a lower risk of complications.
In other words, blood work taken during hospitalization accurately indicated how much omega-3 fats the patients had eaten in the weeks before their heart attack — and the higher the level, the more protection it seemed to afford them.
Yes, they suffered a heart attack, but their complications were much less — and the researchers followed them for three years!
But something even more exciting happened during this study. They learned that both plant and animal sources make for a complementary heart-protective combination…
It turns out that high levels of EPA (derived from fish), are associated with a lower risk of hospital readmission from cardiovascular causes — and that higher levels of the omega-3 alpha-linolenic acid (ALA), derived from plant sources like walnuts, are associated with a reduced risk of death.
The clinical director Antoni Bayes concludes, “marine and vegetable-based omega-3s is an integrative strategy for improving both their quality of life and prognosis if they suffer a heart attack.”
How to get Omega-3s
Omega-3 fatty acids are a type of polyunsaturated fatty acid the body is unable to synthesize on its own and must be obtained through diet. The main dietary source of EPA is from oily fish and includes salmon, mackerel, sardines and herrings. When we eat oily fish regularly it forms a protective barrier of the myocardial membranes and limits the damage caused by a heart attack.
There are also plant sources of omega-3s in nuts and seeds such as flaxseed, chia seeds and walnuts, plant oils such as flaxseeds, soybean oil and canola oils.
Dietary guidelines suggest adults eat at least 8 ounces of seafood per week. But most Americans don’t get that.
Most people look to fish oil to get adequate omega-3s, but many do not know about krill oil supplements. Krill oil is derived from tiny crustaceans called Antarctic krill that are rich in omega-3 fatty acids EPA and DHA. The chemical structure of the fatty acids and red color are the unique differences from fish oil.
Clinical research studies indicate your body absorbs fatty acids in krill oil more easily than from fish oil. One component that is present in krill oil but absent in fish oil is a very powerful antioxidant called astaxanthin. Astaxanthin is the red pigment that gives salmon its red color and helps prevent krill oil from oxidizing. Antioxidants protect your cells from damage from free radicals.
Heart attack prevention
A healthy lifestyle can help keep your arteries strong and plaque-free. Here are tips to improve your heart health:
- Stay physically active
- Stop smoking
- Eat a low-fat, low salt balanced diet
- Maintain a healthy weight
- Control high blood pressure, high cholesterol and glucose levels
- Reduce and manage stress
- Establish a regular sleep routine
Editor’s Note: The results of a $100 million dollar study were recently presented to the American Heart Association. The verdict? Heart procedures don’t seem to help people with stable heart disease avoid heart attacks more than drugs and lifestyle changes do. So before you submit to any heart treatment, discover the truth you won’t find at your doctor’s office: Read this FREE report…
