Flaxseed oil is derived from pressing flaxseeds and is rich in omega-3 fatty acids (primarily alpha-linolenic acid) and lignans. Historically, flaxseed has been used for its laxative properties, in baking, and even in making linen from its fibers.
Flaxseed oil stands out as one of the best plant-based sources of omega-3 fatty acids. It may contribute to improving heart, digestive, skin, and brain health, although more research is needed. Let’s explore the potential benefits of flaxseed oil and the supporting evidence.
Health Benefits of Flaxseed Oil
1. Cancer Prevention
Flaxseed oil contains omega-3 fatty acids and lignans, which may help protect against cancer. The alpha-linolenic acid (ALA) in flaxseed oil has been shown to inhibit tumor growth. Lignans, a type of phytoestrogen, may help prevent hormone-related cancers such as breast and prostate cancer by blocking enzymes involved in hormone metabolism. These phytoestrogens bind to cell receptors, reducing the body’s ability to bind hormones, thus interfering with tumor cell growth and spread.
2. Reduces Inflammation
Research suggests that flaxseed oil may help reduce inflammation, potentially benefiting those who suffer from chronic pain. Due to its omega-3 content, flaxseed oil may be as effective as olive oil in reducing inflammation, particularly in individuals with obesity, according to one study.
3. Supports Heart Health
Studies indicate that flaxseed oil supplements can increase levels of omega-3 fatty acids, including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which are essential for heart health and may help prevent heart disease. The body converts ALA from flaxseed oil into EPA and DHA, making it a natural source of these heart-healthy compounds.
4. Diabetes Prevention
Flaxseed may help improve insulin sensitivity in people with glucose intolerance, possibly due to its antioxidant properties. This could lead to modest improvements in blood sugar levels.
5. Enhances Skin Health
Many users of flaxseed oil, whether applied topically or taken internally, report significant improvements in skin quality within a short period. Several studies support these claims.
6. Promotes Gut Health
Flaxseed oil has natural laxative properties. A study involving 50 hemodialysis patients found that daily flaxseed oil supplementation reduced constipation. Additionally, a small 2012 study on individuals with Irritable Bowel Syndrome (IBS) found that flaxseeds helped reduce inflammation and alleviate IBS symptoms such as constipation and diarrhea.
7. Stroke Prevention
Reducing inflammation in the body can lower the risk of stroke. However, there are also indications that flaxseed oil could potentially increase the risk of stroke, so it’s important to consult with a healthcare provider before starting supplementation.
8. Aids in Weight Loss
Flaxseed oil may support weight loss by promoting digestive health and detoxification. A 2012 study published in the journal Appetite found that flaxseed oil can help suppress appetite, leading to reduced food intake and weight loss.
9. Prevents Dry Eye Syndrome
According to research, a diet high in unhealthy fats may contribute to dry eye syndrome by preventing the oil in the eye glands from flowing properly. The omega-3 fatty acids in flaxseed oil may help thin glandular secretions, allowing for better flow.
10. Eases Menopause Symptoms
Evidence suggests that flaxseed oil may help reduce symptoms of menopause. A 2015 study involving 140 menopausal women found that flaxseed oil supplementation reduced hot flashes and improved overall quality of life.
11. Alleviates Depression
Flaxseed oil, rich in omega-3 fatty acids, contains docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), which are often found at low levels in individuals suffering from major depression. These compounds are also present in walnuts and fish.
12. Regulates Cholesterol Levels
Flaxseed oil, rich in omega-3 and omega-6 fatty acids, can help regulate cholesterol levels, making it a crucial factor in reducing the amount of bad cholesterol in the body.
These are some of the proven health benefits of flaxseed oil. For more insights, consider exploring the benefits of flax oil supplements and drinking flaxseed oil.
