Asparagus Nutrition
and Medicinal Information

Asparagus History | Asparagus Recipes | Growing Asparagus

Asparagus is Low in calories (only 25 per serving!) and sodium,
Asparagus has no fat or cholesterol.

Asparagus is one of the most nutritionally well-balanced vegetables in existence . Has almost as much of all the nutrients as any vegetable you can think of.

Asparagus is the leading supplier among vegetables of folic acid .

A 5.3 ounce serving provides 60% of the recommended daily allowance for folacin which is necessary for blood cell formation, growth, and prevention of liver disease. Folacin has been shown to play a significant role in the prevention of neural tube defects, such as spina bifida, that cause paralysis and death in 2,500 babies each year.
Its wealth of nutrients, fiber and very low sodium and calorie content make asparagus a nutritionally wise choice for today's health-conscious consumer.

Health Benefits
Anti-Inflammatory and Anti-Oxidant Benefits

It's not surprising to see asparagus being heralded as an anti-inflammatory food because it provides a truly unique combination of anti-inflammatory nutrients. Among these anti-inflammatory nutrients are asparagus saponins, including asparanin A, sarsasapogenin, protodioscin, and diosgenin. One of these saponins (sarsasapogenin) has been of special interest in relationship to amyotrophic lateral sclerosis (ALS), also known as "Lou Gehrig's Disease." Even though ALS is classified as a chronic, neurodegenerative disease and is not currently accepted as an autoimmune disorder, excessive, unwanted inflammation may play an important role in the death of certain nerve cells (motor neurons) in ALS. Other anti-inflammatory nutrients in asparagus include the flavonoids quercetin, rutin, kaempferol and isorhamnetin.

Alongside of these anti-inflammatory phytonutrients, asparagus provides a wide variety of antioxidant nutrients, including vitamin C, beta-carotene, and the minerals zinc, manganese, and selenium. (Asparagus also contains a small amount of vitamin Eâ€"about 1.0-1.5 mg per cup).

In addition to the antioxidant nutrients above, this much-loved vegetable may also contain a valuable amount of the antioxidant glutathione (GSH). GSH is one of the body's best-studied antioxidants; it consists of three amino acidsâ€"glutamic acid, glycine, and cysteineâ€"combined into one molecule. At least one published study has estimated the amount of GSH in fresh asparagus to average 28 milligrams per 3.5 ounces. Several studies have compared the overall antioxidant capacity of asparagus to the antioxidant capacity of other vegetables, and the results for asparagus have been impressive. Asparagus compares favorably with many of the cruciferous vegetables like cabbage and cauliflower, and while it ranks lower than some of the green leafy vegetables like spinach, it is still very high on the list of antioxidant foods.

Anti-inflammatory and antioxidant nutrients are some of the best risk reducers we know for common chronic health problems including type 2 diabetes and heart disease. These nutrients are also special risk reducers in the case of certain cancerâ€"a special area of asparagus health benefits that is covered in the following section.

Digestive Support

As described earlier in our "What's New and Beneficial about Asparagus" section, asparagus is unusual as a digestive support food. One key factor in this regard is its inulin content. Like chicory root and Jerusalem artichoke, asparagus contains significant amounts of the nutrient inulin. Inulin is a unique type of carbohydrate called a polyfructan, and in practical terms, healthcare practitioners often refer to it as a "prebiotic." Unlike most other carbs, inulin doesn't get broken down in the first segments of our digestive tract. It passes undigested all the way to our large intestine. Once it arrives at our large intestine, it becomes an ideal food source for certain types of bacteria (like Bifidobacteria and Lactobacilli) that are associated with better nutrient absorption, lower risk of allergy, and lower risk of colon cancer. While approximately 5% lower in inulin than chicory root and Jerusalem artichoke, asparagus is a food that contains a valuable amount of this unique carb and can help support our digestive health in this unique way.

Alongside of its unusual inulin content, asparagus is rich in fiber (about 3 grams per cup, including about 2 grams of insoluble fiber and 1 gram of soluble fiber) and also contains a noteworthy amount of protein (about 4-5 grams per cup). Both fiber and protein help stabilize our digestion and keep food moving through us at the desirable rate. (By contrast, too much fat can slow down our digestion rate more than desired, and too much sugar or simple starch can speed it up more than desired. We're not surprised to see species of asparagus like Asparagus racemosus (commonly known as Shatavari) having a long history of use in treatment of digestive problems in certain healthcare traditions (like ayurvedic medicine), and it makes sense to us that asparagus be considered as a great food for improving digestive support in most diets.

Heart Health and Blood Sugar Regulation

While we have yet to see large-scale dietary studies that examine chronic diseases in humans and asparagus intake, we would expect asparagus intake to show reduced chronic disease risk in two particular areas, namely, heart disease and type 2 diabetes. While there is some preliminary research in both areas, both areas need more attention from asparagus researchers. Our desire to see more research in these areas is based on several factors.

First is the amazing B-vitamin content of asparagus. In our food rating system, asparagus emerges as an excellent source of folic acid and a very good source of vitamins B1, B2, B3 and B6. Asparagus also contains the B vitamins choline, biotin, and pantothenic acid. Because B vitamins play a key role in the metabolism of sugars and starches, they are critical for healthy blood sugar management. And because they play a key role in regulation of homocysteine, they are critical in heart health has well. (Homocysteine is an amino acid, and when it reaches excessive levels in our blood, it is a strong risk factor for heart disease.)

Second, along with its impressive list of B vitamins, asparagus provides us with about 3 grams of dietary fiber per cup, including more than 1 gram of soluble fiber. Intake of soluble fiber has repeatedly been shown to lower our risk of heart disease, and our risk of type 2 diabetes can be significantly lowered as our intake of dietary fiber increases.

Finally, there is the anti-inflammatory/antioxidant factor. Heart disease and type 2 diabetes are both considered chronic diseases that evolve in relationship to chronic, excessive inflammation and oxidative stress. The outstanding antioxidant and anti-inflammatory nutrient composition of asparagus would seem to make it a no-brainer for inclusion as a risk reducer in both of these chronic disease areas. We expect future studies to establish asparagus as a standout for lowering our risk of cardiovascular and blood sugar problems.

Anti-Cancer Benefits

As a result of its very strong anti-inflammatory and antioxidant nutrient composition, we would definitely expect to see a food like asparagus showing up as a risk reducer for certain cancers. Chronic, excessive inflammation and chronic oxidative stress are risk factors for a variety of cancer types, and both unwanted phenomena are related to deficient dietary intake of anti-inflammatory and antioxidant nutrientsâ€"exactly the kind of nutrients that are especially plentiful in asparagus. Most of the studies we've seen on the anti-cancer benefits of asparagus have been studies on rats and mice, or studies on specific types of cancer cells. For this reason, we would describe asparagus cancer research as preliminary, and not yet validated by large-scale studies involving humans and dietary intake. But the trends in animal studies and cell studies are clear - asparagus and asparagus extracts can change the metabolic activity of cancer cell types, and these changes are protective in nature and related to better regulation of inflammation and oxidative stress. Cancer cells from the liver are best-studied in this regard.

One confusing area of research on asparagus and cancer involves leukemia. And while this arena has focused upon enzymes related to an amino acid in asparagus, rather than asparagus itself, we thought to include information on it here to clarify this arena for you in case you had come across information on this topic.

Leukemia is a type of cancer involving the bone marrow and its production of white blood cells. In leukemia, white blood cells are not produced in a normal way and do not behave in a normal way, and for these reasons are called leukemia cells. One unusual aspect of leukemia cells is their need to obtain a specific amino acid called asparagine from other cells or from the fluid portion of the blood. If leukemia cells can be prevented from obtaining asparagine, they can sometimes have difficulty surviving. In the mid-1950's and 1960's, researchers discovered that the injection of an enzyme called asparaginase into persons diagnosed with leukemia could sometimes result in decreased levels of blood asparagine in the blood and selective destruction of leukemia cells through asparagine deprivation. Prescription injection of asparaginase enzymes is still used in treatment of acute lymphoblastic leukemia (ALL). Asparagus has become entangled in this fascinating set of events involving leukemia because the name of the amino acid "asparagine" and the name of the enzyme "asparaginase" clearly imply a connection with asparagus. Both the amino acid and the enzyme are present in asparagus, just as their names imply. However, we are not aware of any research showing a treatment connection between leukemia and dietary intake of asparagus. The only research we've seen involves injection of the purified, prescription enzyme medication. In addition, we know that pharmaceutical companies do not use asparagus as a source of the asparaginase enzyme, but rather, rely on bacteria as their enzyme production source.
