Omega 3 Fatty acids
Importance & Benefits -1
  • Omega 3 food
  • Omega-3 fatty acids are considered essential fatty acids: They are necessary for human health but the body can' t make them -- you have to get them through food.
    Also known as polyunsaturated fatty acids (PUFAs), omega-3 fatty acids play a crucial role in brain function as well as normal growth and development. They have also become popular because they may reduce the risk of heart disease. The American Heart Association recommends eating fish (particularly fatty fish such as mackerel, lake trout, herring, sardines, albacore tuna, and salmon) at least 2 times a week.. The short chain n−3 fatty acids are converted to long chain forms (EPA, DHA) with an efficiency of approximately 5% in men, and at a greater percentage in women.

Where is the omega-3?
Omega-3 fatty acids can be found in fish, such as salmon, tuna, and halibut, other seafood including algae and krill, some plants, and nut oils.
The Mediterranean diet has a healthier balance between omega-3 and omega-6 fatty acids.
Many studies have shown that people who follow this diet are less likely to develop heart disease.
The Mediterranean diet does not include much meat (which is high in omega-6 fatty acids) and emphasizes foods rich in omega-3 fatty acids, including whole grains, fresh fruits and vegetables, fish, olive oil, garlic.

What is the importance of omega-3 for the human body?

Omega-3 and the Brain:
  • Research has found clinical and laboratory importance of omega-3 fatty acids in protecting brain cells and thus its functioning to the fullest, they are at the core of the walls of these cells and thus providing them the flexibility necessary to receive the signals from other cells and send them unlike saturated fatty acids that make the cell membranes allow the passage of harsh vector and nerve signals through with ease.
  • Omega-3 fats benefit in the prevention of blood clots and raised a lot of strokes, as it affects the coagulation mechanisms (such as aspirin), and even in the event of a stroke, the harm resulting therefrom shall be less if the levels of omega-3 fatty acids at high .
  • As Investigations have shown that mental performance in older people be better dealt with approximately 75 grams of fish per day.
  • British researchers found in another study that patients with Baltlosm improved their condition after eating for 480 mg of omega-3 daily for a month.
  • There is also evidence that omega-3 may help to raise the rates of mental activity in adults as measured by the rate of transmission of brain waves known as the P300 and its relationship to learning and memory and cognition.

Studies have found mixed results as to whether taking omega-3 fatty acids can help depression symptoms. Several studies have found that people who took omega-3 fatty acids in addition to prescription antidepressants had a greater improvement in symptoms than those who took antidepressants alone. However, other studies have found no benefit.
Studies are also mixed on whether omega-3 fatty acids alone have any effect on depression. Depression is a serious illness and you should not try to treat it on your own. See a doctor for help.

Bipolar disorder
In a clinical study of 30 people with bipolar disorder, those who took fish oil in addition to standard prescription treatments for bipolar disorder for 4 months experienced fewer mood swings and relapse than those who received placebo. But another 4-month long clinical study treating people with bipolar depression and rapid cycling bipolar disorder did not find that EPA helped reduce symptoms.

Preliminary clinical evidence suggests that people with schizophrenia may have an improvement in symptoms when given omega-3 fatty acids. However, a recent well-designed study concluded that EPA supplements are no better than placebo in improving symptoms of this condition.

Attention deficit/hyperactivity disorder (ADHD)
Children with attention deficit/hyperactivity disorder (ADHD) may have low levels of certain essential fatty acids (including EPA and DHA). In a clinical study of nearly 100 boys, those with lower levels of omega-3 fatty acids had more learning and behavioral problems (such as temper tantrums and sleep disturbances) than boys with normal omega-3 fatty acid levels.
However, studies examining whether omega-3 fatty acids help improve symptoms of ADHD have found mixed results. A few studies have found that omega-3 fatty acids helped improve behavioral symptoms, but most were not well designed. One study that looked at DHA in addition to stimulant therapy (standard therapy for ADHD) found no effect. More research is needed, but eating foods that are high in omega-3 fatty acids is a reasonable approach for someone with ADHD.

Omega-3 and bowel disease:
Duodenal Ulcer:
A number of studies have proven that omega-3 may help in reducing the symptoms of different types of ulcers that affect the digestive system, such as duodenal ulcers and Crohn's disease. In a study of 78 patients with Crohn's disease.
The symptoms of the disease was decreased by 33% to 78% after using them for 3 grams of fish oil/day. In a further study on patients with duodenal ulcer , 72% of patients who have used the fish oil had grown rich or totally underestimated dose of drugs used sedatives for the disease.

Inflammatory bowel disease (IBD)
Results are mixed as to whether omega-3 fatty acids can help reduce symptoms of Crohn' s disease and ulcerative colitis, the two types of IBD. Some studies suggest that omega-3 fatty acids may help when added to medication, such as sulfasalazine (a standard medication for IBD). Others find no effect. More studies are needed. Fish oil supplements can cause side effects that are similar to symptoms of IBD (such as flatulence, belching, bloating, and diarrhea).

Colon cancer
Eating foods rich in omega-3 fatty acids seems to reduce the risk of colorectal cancer. For example, Eskimos, who tend to have a high-fat diet but eat significant amounts of fish rich in omega-3 fatty acids, have a low rate of colorectal cancer. Animal studies and laboratory studies have found that omega-3 fatty acids prevent worsening of colon cancer. Preliminary studies suggest that taking fish oil daily may help slow the progression of colon cancer in people with early stages of the disease. If you have colorectal cancer, ask your doctor before taking any supplements.
