Why the fuss over omega-3 fatty acids?

They are often called "essential" fatty acids (EFAs) since researchers have found that children need these nutrients in their diet to maintain health and normal growth patterns.

For adults, the most substantial health benefits provided by omega-3 fatty acids are related to the heart and circulation. In numerous studies, researchers have found that omega-3 fatty acids lower the risk of heart attack, improve circulation, reduce high blood pressure, and help to break down fibrin, which is a compound that contributes to the formation of scars and clots.

Found in certain foods and supplements, omega-3 fatty acids have been linked to a wide-range of other health benefits, including reduced risk of heart disease, arthritis, rheumatoid arthritis, lupus, and asthma.

Several studies have demonstrated that omega-3 fatty acids have a neuroprotective effect, meaning they help protect the brain and nervous system. This effect is particularly important for those who have either Parkinson's disease or Alzheimer's disease. Both of these diseases cause the breakdown of nerve cells, and omega-3 fatty acids protect against this degenerative effect.

For the same reason, there is also evidence to suggest that omega-3 fatty acids may be beneficial to those suffering from depression and anxiety.

In related studies, omega-3 fatty acids also show benefits for child development and in improving cognition. In one study, children who had been selected specifically for their poor learning in school were given large doses of omega-3 fatty acids daily. The researchers then asked parents to rate their children's performance 15 weeks and 30 weeks after the study started. The result was that the children taking omega-3 fatty acids did significantly better on a whole range of measures of learning and cognitive ability.

There is also limited evidence to suggest that omega-3 fatty acids may be beneficial to cancer patients. Results have been quite mixed, but there are many studies that show omega-3 fatty acids do help combat cancer. Specifically, there have been studies that show clear health benefits to those suffering from colon cancer, prostate cancer, and breast cancer.

The vast majority of people do not get nearly enough omega-3 fatty acids in their diet, and so supplements are certainly a good idea.

By eating a diet rich in fish, nuts, eggs, meat and dairy products, most people can get enough of the combination of alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA) that add up to what are known as omega-3 fatty acids. You may also find them referred to as polyunsaturated fatty acids (PUFAs) because they are made up of chains of polyunsaturated fat molecules.

Organic eggs, milk and cheeses have a much higher amount of essential fatty acids. Moreover, grain fed cows tend to produce milk with less of these essential nutrients than cows allowed to graze on grass.

The American Heart Association recommends a variety of fish (preferably oily such as shrimp, canned light tuna, salmon, pollock, and catfish) at least twice per week. They also suggest that you include oils and foods rich in alpha-linolenic acid (flaxseed, canola, and soybean oils; flaxseeds and walnuts) in your diet.
