Among their many health benefits flax seeds help reduce risk of cardiovascular disease, lower cholesterol, protect against type II diabetes, fight cancer, and prevent chronic kidney disease.

Most of these benefits come from the omega 3 fatty acids (alpha-linolenic acids) found in flax seeds. Flax also contains a lot of lignans which contribute to all its health benefits.

Flax Seeds Health Benefits

1. Flax Seeds Reduce Risk of Cardiovascular Disease

Flax seeds are a great source of Omega 3 fatty acids and lignans, both of which are theorized to have a protective effect on the heart and cardiovascular system (1,2). This is due to Omega 3s and lignans ability to reduce blood pressure, lower cholesterol, lower blood glucose, and even combat the damaging effects of mental stress (3).

4. Flax fights against tumors and cancer

Research, primarily on rats, has shown that flax seeds can prevent the growth of colon, breast, skin, and lung tumors (6). Similar to reducing the risk of diabetes, this might be in part to flax's ability to lower blood sugar, insulin, and insulin-like growth factor (IGF1). Flax further fights breast cancer since contains compounds which mimic estrogen, thus blocking estrogen absorption in the body (7).
