What Are Omega-3 Fatty Acids?
Omega-3 fatty acids are essential to health but are not made by the body. They must be obtained through food. Omega-3 has antioxidant properties and is essential to normal human growth and development, as well as brain functions. Omega-3 fatty acids, also known as polyunsaturated fatty acids, are divided into three categories: Alpha-linolenic acid (ALA), docosahexaenoic acid (DHA), and eicosapentaenoic acid (EPA). EPA and DHA are the fatty acids used the most by the body.
Symptoms of Omega-3 fatty acid deficiency include depression, dry skin, fatigue, hair loss, heart disease, poor circulation and poor memory. Those who feel their symptoms may be caused by a deficiency of Omega-3 should consult their physician.
Benefits of Omega-3 Fatty Acids
Studies show that omega-3 may lower high cholesterol levels and blood pressure in those who suffer from hypertension. Eating a low-fat diet that includes omega-3 may reduce the risk of heart disease and prevent blood clots from developing. Those who take omega-3 fatty acid supplements have a decreased risk of death and stroke.
Omega-3 supplements decrease inflammation and may ease the suffering of those with joint problems, like arthritis, by reducing stiffness and pain. Omega-3 may also increase calcium levels in the body, thus lowering the risk of osteoporosis and increasing bone density, particularly among women.
Fatty acids may help to protect the skin from UV rays. Evidence suggests that it may also heal wounds and burns. Those who take omega-3 also have a lower risk of developing macular degeneration, an eye disease related to aging.
When taken with medication, omega-3 may reduce the symptoms of some bowel disorders like Colitis and Crohn's disease. There is evidence that it may also reduce the risk of colon cancer and stop the growth of tumors. Women whose diet is rich in omega-3 have a lower risk of developing breast cancer. It may also inhibit the growth of prostate cancer.
People with a deficiency of omega-3 may experience depression. Eating a diet rich in omega-3 may reduce instances of depression. It may also lessen mood swings and reduce manic episodes in those who suffer from Bipolar disorder.
Cold water fish are the best source of omega-3 fatty acids. The American Heart Association recommends that people without heart disease consume fish at least twice a week, along with foods that contain ALA, like walnuts, tofu, soybeans and canola oil. Flaxseed, broccoli, cabbage, kidney beans, and spinach are other good source of omega-3.
A recent study conducted by Harvard School of Public Health researchers found that 96,000 preventable deaths occur a year due to omega-3 deficiency, and is the 6th highest killer of Americans. For this reason, it is important to get the necessary daily requirements of omega-3 to prevent serious life threatening illnesses.
