Asparagus: Cancer cure?

As much as I dislike facebook, I must admit, it sometimes comes in handy for blog fodder. For instance, the post about asparagus that someone in my timeline recently shared. Now, I don’t want to discourage anyone from eating asparagus. Asparagus is both amazingly delicious and extremely nutritious. However, I feel compelled to refute some of the erroneous information in the post.

The post begins:

Subject: Asparagus DO NOT FAIL TO READ THIS AND SEND TO YOUR FAMILY &FRIENDS When I was in the USN, I was stationed in Key West, FL. I worked at the clin…ic at Naval Air Station on Big Coppitt Key just a few miles north of Key West.

Ever notice how the ridiculous posts on FB claiming to provide miracle cures and medical information always include extraneous details about the poster? I mean, who cares if you were in the navy and where you were stationed? This somehow lends credibility to your claims to have knowledge about nutrition and science? Apparently some people must think so, as I can think of no other reason why people continue to share these posts. Anyway…

The author claimed that some old man (a retired biochemist) told him that the reason why asparagus makes your pee smell is because it “is detoxifying your body of harmful chemicals!!!”. Sure glad that biochemist is retired! The real reason that your pee smells is because your body is breaking down sulfurous amino acids in the asparagus and excreting them in your urine. No food has the power to rid your body of harmful chemicals. Sorry.

The post then goes on to provide “evidence”, via four “cases”, that asparagus can cure cancer. The reason why asparagus can do this is alleged to be the presence of “histones“. These are alkaline proteins. Some histones may, in fact, be promising in the development of a cure for cancer. Regardless, while asparagus does contain histones, so do other foods such as all cruciferous vegetables, nuts, seeds, wheat, egg yolks, milk, garlic, etc.

Asparagus is undoubtedly a healthy food choice. Consumption of it, and other vegetables, and other whole foods, may reduce your risk of developing cancer. However, it’s giving false hope to people to tell them that they can cure their existing cancer by drinking two tablespoons of asparagus puree daily. Eat lots of vegetables, eat a variety of them. Don’t look to anyone food to save your life.
