There is no scientific evidence that asparagus is useful for the treatment of cancer, according to Dana-Farber Cancer Institute. During the 1950s, a theoretical link was made between cancer and asparagus, but as of 2015, research has not supported this proposal.
The February 1974 issue of Prevention magazine contained an article highlighting the benefits of asparagus in the fight against cancer, relates About.com. However, no peer-reviewed medical journals have reported this link.
Like many plant-based foods, asparagus contains phytonutrients, which help prevent cancer, Dana-Farber Cancer Institute states. Along with other vegetables, fruits and grains, asparagus is a healthy dietary choice for people with cancer, but it does not seem to contain any special curative qualities.
Asparagus has many nutritional benefits. It has no fat or cholesterol and little sodium, says the Michigan Asparagus Advisory Board. The vegetable contains significant amounts of vitamin B6, thiamine, fiber, potassium and vitamin C. Asparagus is an excellent source of rutin, which helps strengthen capillary walls.
One serving of asparagus contains 60 percent of the recommended daily allowance of folic acid, which helps form blood cells and ward off liver disease, MAAB notes. The nutrient is also crucial for preventing neural tube birth defects such as spina bifida.
Asparagus has been proposed as beneficial for many conditions, but no proof of these benefits has yet been discovered, warns WebMD. These conditions include urinary tract infections, AIDS, kidney stones, anemia and female hormone imbalance.
