Top Health Promoting Components
The top health promoting components in blueberries include:

Anthocyanidins - is an antioxidant that neutralizes free radical damage to the collagen matrix of cells and tissues that can lead to cataracts, glaucoma, varicose veins, hemorrhoids, peptic ulcers, heart disease and cancer.

Pterostilben - is an antioxidant that is shown to help fight cancer, heart disease, and lower LDL cholesterol.

Ellagic acid - is an antioxidant compound than blocks metabolic pathways that can lead to cancer.

Soluable fiber - forms a gel in the digestive tract that binds onto the bile, eliminating it with the bowel movement. Since bile contains cholesterol, and the bile is removed, the body must make more. To do so, it takes cholesterol out of the bloodstream.

Insoluable fiber - is not absorbed by the body. Its health benefits include aiding digestion and promoting regularity by adding bulk. The "bulk" keeps other foods moving through the digestive tract.

Tannins - act as astringents in the digestive system to reduce inflammation.
