The nation’s interest in flaxseed has exploded in recent years as flaxseed is thought to have many beneficial effects on the body. Flaxseed is the seed from the Linumusitatissimum plant - the seed and seed oil are used as food and can be found in many medications. Common food products that contain flaxseed include crackers and oatmeal. Flaxseed contains protein and offers many nutritional and health benefits. The main three nutritional benefits of flaxseed are:
- Omega-3 Fatty Acids. Flaxseed contains alpha-linoleic acid, an omega-3 fatty acid. These fatty acids are considered “healthy fats,” and can help improve heart health, lower triglyceride levels, and aid in the treatment of inflammatory bowel disease and arthritis. One tablespoon of ground flaxseed has around 1.8 grams of omega-3.
- Lignans Lignans can help lower blood cholesterol and improve atherosclerosis. Lignans in flaxseed have been shown to reduce total cholesterol levels and LDL (bad cholesterol) levels. However, flaxseed does not appear to improve HDL (good cholesterol) levels. Lignans also have antioxidant properties which help protect the body’s cells from harmful compounds called free radicals. Flaxseed may contain as much as 800 times more lignans than most other plant foods.
- Fiber Flaxseed contains both soluble and insoluble fiber. Fiber is an important part of digestive health, weight maintenance, and blood cholesterol control. Fiber from flaxseed may help manage constipation, diarrhea, irritable bowel syndrome (IBS) or irritable colon, diverticulitis (inflammation of the lining in the large intestine), ulcerative colitis (ulcers in the large intestine lining), gastritis (inflammation of the stomach lining), and enteritis (inflammation of the small intestine). Although flaxseed may help with the above conditions, it is not advised for all. If taken without sufficient water, flaxseed can cause constipation or even a bowel obstruction. Most of the fiber found in flaxseed is located in the seed coat, so consuming flaxseed oil will not provide a significant amount of fiber.
