SOURCES AND IMPORTANTS OF OMEGA-3 FATTY ACIDS

The major source of polyunsaturated fats is omega-3 fatty acids.  Sources of omega 3 are fish and dietary supplements made from fish or algae. Researches have shown that fish oil can dramatically help reduce the risk of heart disease. The effect of these oils is so powerful that in 2002, the American Heart association summarized research and recommended that healthy people include omega-3 fatty acids from fish and plant sources to protect their hearts.
For diabetic patients, the value of  fish also comes from the omega-3 fatty acids it contains.

Omega-3 fatty acid

can raise high density lipoprotein cholesterol slightly, which have little or no effect on Low density lipoprotein cholesterol,  and can significantly help to lower triglycerides. In fact, a meta-analysis in 1998 of 26 different studies showed that fish oil supplements, which are nothing but omega-3 fatty acids, lower triglycerides by almost 30 percent. Omega-3 supplements also help in decreasing inflammatory responses which, as you know, is beneficial in the treatment of cardiovascular disease, diabetes, and the metabolic syndrome.
Eating cold-water fatty fish, such as tuna, salmon, mackerel, anchovies, sardines, herring, or eel, is one way to get the benefits of omega-3 fatty acids, as is taking fish oil supplements and we know it works because most studies are based on people consuming fish or fish oil.
A few studies of omega-3 fatty acids have suggested that taking them in supplement form could raise blood sugar; a few other studies have suggested that omega-3 supplements actually improve insulin sensitivity.
To find out for sure, in 1995, researchers conducted a randomized, double-blind,placebo-controlled trial using 4 grams of fish oil a day for some diabetic patients and 4 grams of corn oil for others. After 16 weeks, the fish oil had no effect on the blood sugar of the people who took it. It did, however, slightly lower their blood pressure; it also modestly lowered their triglycerides.
You can get omega-3s from plant sources such as algae and flaxseed oil. Like fish oil, flaxseed oil and other plant sources can help control blood lipids and prevent heart attacks.
