Many varieties of asparagus exist, but only 1 is readily available today: green asparagus. If you are lucky, you may occasionally spot a purple or white variety. Asparagus, a vibrant, spring vegetable, has some serious health benefits. With over 100 known potent compounds, asparagus may be just what the doctor ordered. Find out my journey to loving asparagus, the history of this cool plant, asparagus health benefits, and how to cook and prepare it.
Taste training for asparagus
“You need to eat at least one,” said my parents every time we sat down in the spring to eat asparagus. With reluctance, I would muster up the will to chew up that bite of the distinctly agonizing flavor of none other than asparagus.
Now I hear those same words coming out of my mouth with dictum of “you need to eat at least one spear.”
Mom and Dad got it right. Whether it was intentional or not, they were training our taste buds to have a broad palate for healthy things.
Learning to Love Asparagus
One day, I overcame the loathing of this speared vegetable, almost as if a flip switched.
By the time I was in high school, one of my best friends, Kathleen, decided I should have a band called Heidi Loves Asparagus. It was the 90’s when everyone came up with some kitschy name for a band that they dreamed of being in.
My taste buds had developed in my teens. Thank you, Mom and Dad. I never had the fortitude to start that band, but the inspiration of asparagus still holds my attention today.
Asparagus is really like no other when it comes to vegetables. And I mean that in a good way.
How To Buy Asparagus
Unlike most vegetables, where the smaller and thinner are the more tender, thick asparagus stalks have a more tender volume to the proportion of skin. Try to find compact tips that are not shriveled.
There are an estimated 432 species of Asparagus, or Asparagaceae, but only one readily available in stores today: Asparagus officinalis .
Purple asparagus was originally developed in Italy and was commercialized under the variety name “Violetto d’Albenga.” Purple asparagus is the same species of asparagus as the green asparagus, but is a slightly different variant of this species. It has a more mild and sweet flavor.
White asparagus is just green asparagus that is deprived of light during its growing period. Its harvest is very labor-intensive.
History of Asparagus
Asparagus is Greek term, but it may have been borrowed from the Persian word asparag, meaning sprout or shoot.
Asparagus has been eaten since antiquity. Asparagus appears in the oldest surviving cookbook as well, known as Apicius’s 3rd century CE De re coquinaria, Book III.
Asparagus Sexual Function and Sexual Habit
Male and female asparagus are different: the females produce little berries later in the season (they are not edible). The male plants have more prolific stalks.
Queen Nefertiti proclaimed asparagus to be the food of the Gods. It also has been proclaimed an aphrodisiac throughout history, with its spear-shape exemplifying this legend.
Legend has it that if asparagus is eaten for three consecutive days, it has more potent sexual effects.
Asparagus Taste and Potency
Asparagus is seriously nutritious.
But the “nutrients” in no way explain its out-of-this-world taste. How did it get this potent taste? Potency in nature in regards to taste usually translates to potency in health.
Asparagusic acid is a sulfur compound that is thought to be responsible for its pungent taste and also its pungent effect on the smell of your urine.
Don’t smell it? It’s likely because of your genes. Less than 10% of people are unable to smell the distinct asparagus smell when they urinate .
Asparagusic acid is unique to asparagus in nature. Pretty amazing.

Does Asparagus Have a Dark Side?
For all intents and purposes, no. But the headlines in February were setting off alarms about asparagus and breast cancer triple negative cells .
Why were these headlines problematic?
Asparagus has not one, but over 100 compounds in it, most are linked to reducing cancer risk. the compound they studied isolated asparagine. This compound is never seen isolated in real life. It isn’t even available as an isolated compound for public use.
Asparagus is one of many foods that contain this particular amino acid.
Keeping it in Perspective
