Major benefits derived from asparagus are listed below.

Heart Care : Asparagus provides about 3 gm of dietary fiber per cup which helps in reducing risk of heart related diseases. The rich source of multivitamins in asparagus regulates homocysteine and hence is critical in heart care. Both heart disease and type 2 diabetes are the result of excessive inflammation and oxidative stress. The excellent antioxidant and anti-inflammatory properties of asparagus reduces the risk of both the diseases.

Blood Sugar Regulation : Asparagus is a rich source of vitamins B1, B2, B3, B2 and folic acid along with B vitamins choline, pantothenic and biotin. These vitamins help in blood sugar metabolism, hence asparagus is considered competent in blood sugar management.

Anti Inflammatory Benefits : Asparagus provides saponins which include; asparnin A, sarsasapogenin, protodioscin and diosgenin which are considered as anti inflammatory nutrients. Flavonoids, quercetin, rutin, isorhamnetin and kaempferol are other anti inflammatory nutrients found in asparagus.

Anti-Oxidant Benefits : Asparagus is rich in antioxidant nutrients. These include vitamin C, vitamin E, beta-carotene and glutathione; minerals zinc, selenium and manganese. Glutathione consists three amino acids- glycine, cysteine and glutamic acid-combined in to one molecule. A study has shown that the fresh asparagus contains about 28 mg per 3.5 ounces of glutathione. Asparagus benefits

Anti Cancer Benefits : Chronic oxidative stress and chronic inflammation are considered as risk factors for many types of cancer. These are again connected to insufficient intake of anti inflammatory and anti oxidant nutrients. Asparagus help overcome this due to its rich content of these nutrients.

Benefits for digestion : Another health benefit of asparagus is that it is considered as a digestive support food because it contains considerable amounts of nutrient inulin. Healthcare experts consider this inulin as prebiotic because it contains a type of carbohydrate called as polyfructon. Inulin helps certain types of bacteria to grow in the large intestine. These bacteria are known to reduce the risk of colon cancer. Asparagus is rich in fiber content (about 2 gm of insoluble fiber and 1 gm of soluble fiber in a cup) along with about 5 gm of protein per cup. Both these ingredients; fiber and protein help in stabilizing digestion.

Anti-aging benefits : Asparagus has proved to prolong the process of aging by keeping muscle tissues healthy. Being rich in folate, potassium, glutathione and vitamin A, asparagus acts as an anti-aging food. It keeps the body free of free radicals. It also fights cognitive decline in the brain.

Benefits for the skeletal system : High vitamin K content present in asparagus helps in keeping bone density high and preventing problems such as osteoporosis and osteoarthritis. The vitamin helps in formation of bones and in repairing damages due to wear and tear. Asparagus is the biggest source of vitamin K.

Benefits for pregnant women and fetus : High folate content present in asparagus helps in promoting fetal health in the womb, thus preventing birth defects in the baby. It is also good for women who are trying to conceive. Deficiency of folate can lead to damages in the spinal cord of the baby and to a condition called anencephly, which is a defect of the neural tube. Asparagus helps in good formation of nerve cells in the fetus and is also known to prevent premature births.

When not to use Asparagus

Leukaemia cells responsible for blood cancer depend on asparagines, a particular type of amino acid, for survival. Even though there is no conclusive study to prove the relationship, amino acid "asparagines" present in asparagus may aggravate the condition of blood cancer. Purines contained in asparagus may be broken down in to uric acid. Excessive intake of purine can result in gout and formation of kidney stones.
