Your body needs omega-3 fatty acids in order to properly function. It doesn’t produce them, however, you need to eat foods that contain them.
Studies show that omega-3 fatty acids can help a host of health conditions. Here’s a sampling of the benefits that you might realize if you eat a diet high in omega-3 fatty acids. In some instances, more studies need to be done to confirm results.
- It may increase your HDL or good cholesterol levels and decrease triglycerides (fats in blood).
- It may lower high blood pressure.
- It may prevent heart disease and stroke.
- It may help people with diabetes, because it can help to lower triglycerides and apoproteins (markers of diabetes).
- It may help to reduce symptoms of rheumatoid arthritis, such as joint pain and morning stiffness. It might also increase the effectiveness of anti-inflammatory drugs.
- It may lower inflammation associated with asthma.
- It may prevent symptoms of systemic lupus, such as fatigue and joint pain.
- It may increase calcium levels, improve bone strength, and decrease bone loss associated with osteoporosis.
- It may reduce your chances of getting macular degeneration.
- It may lower your risk for colon cancer, or slow the progression of it in the early stages.
- It may prevent men from getting prostate cancer.
- It may lower your level of depression while boosting the effect of anti-depressants. It may also lower depressive symptoms of bipolar disorder.
- It may decrease your risk for cognitive decline or dementia, such as Alzheimer’s disease, and slow its progression. Some researchers believe omega-3s protect against these conditions.
If a pregnant woman doesn’t consume enough omega-3 fatty acids, her unborn baby is at greater risk for having nerve and vision problems.
If you do not eat enough omega-3s, you may experience fatigue, memory problems, heart issues, poor circulation, dry skin, mood swings, or depression.
Food sources
