Today’s menu spotlight is asparagus, which is why I want to address the stinky elephant in the room right off the bat. Yes, most people experience some unpleasant odors when they visit the restroom after eating asparagus. The reason why is a chemical contained exclusively in asparagus known as asparagusic acid.
Clever name right?
When digested, this chemical produces foul-smelling sulfur-containing compounds. As unpleasant as this olfactory side effect may be, it pales in comparison to the health benefits eating asparagus can provide (source).
Asparagus is full of healthy micronutrients but the one that is most prominent is vitamin K. One cup of asparagus contains over 100% of our daily value (DV) for vitamin K. This vitamin is essentially necessary for blood clotting. Studies have also found that the vitamin K in asparagus could help increase bone density, while decrease fracture rates among individuals with osteoporosis (source). The health benefits of vitamin K are extremely important, but asparagus contains a large amount of a another nutrient that I’m much more interested in, especially at this point in my life.
The day this blog is posted, my wife Shannon will be 27 weeks pregnant. Anyone that has gone through this process knows that proper nutrition is a HUGE part of a healthy pregnancy. One component of pregnancy nutrition is making sure the woman receives an adequate amount of certain nutrients. Folate happens to be one of those nutrients and asparagus contains over 60% of our DV per cup. Folate aids in several functions critical to a developing fetus like preventing neural-tube defects, red blood cell formation and DNA construction (source).
Which is why it’s safe to assume that I’ve been essentially force feeding Shannon anything high in folate over the last six months. We’ll have to cross asparagus off that list soon because its peak growing season has nearly ended and freshness definitely affects the plant’s nutrient density.
Asparagus is a spring time crop. Yes you can buy canned and frozen asparagus year round, but the plant’s biology drastically reduces its available nutrients once it’s harvested. You may not know this but plants don’t instantly “die” once they’re picked. Metabolic functions continue to occur and in asparagus, these functions occur at a very rapid rate. In fact, asparagus’ post harvest “metabolism” is approximately 5 times greater than onions and potatoes stored at room temperature. This fact is why the George Mateljan Foundation recommends eating asparagus within 48 hours of purchasing (source).
Hopefully this post inspires you to grab some fresh asparagus if you see it at the grocery store or farmer’s market this weekend. It may be your last opportunity! If you do grab an asparagus bunch during your next shopping trip, please let us know. Feel free to snap a pic and tweet it to us or post it on our Facebook page (Facebook, Instagram or Twitter). We want to know if you were able to enjoy fresh asparagus before the season ends this year.
