So often when I am the local grocery store I question whether or not to purchase the “conventional” or “organic” vegetables. The price tag steers me toward the conventional ones; however, I am well informed about “the dirty dozen” (those vegetables and fruits we want chemical-free which include apples, celery, strawberries, peaches, spinach, nectarines, gapes, sweet bell peppers, potatoes, blueberries, lettuce and kale), and do try to steer clear of those, unless they are organic.
This little video about a 4th grader’s science experiment called “the potato project” caught my attention. Elise goes to the store with her grandma and they purchase 3 sweet potatoes, all from different sources. One comes from the grocery store, one actually comes from the same store and is labeled “organic” and one is from a certified organic food market called Roots.
Elise places each of them in a glass of water and begins to see what vine growth and sprouts occur. After 3 weeks the one from the grocery store does not have any, the second one (which was labeled organic from the grocery) has a sorry little vine which has taken over a month to produce. The third sweet potato (bless its little heart) ~ the certified organic one from Roots, begins to produce beautiful healthy vines just after one week.
Elise then learned from the grocer that the first potato had been sprayed with “bud nip.” and that explained why there was no vine growth. What is bud nip? A commonly used chemical herbicide and one ingredient in it is chlorpropham. 75% of Potatoes contain chlorpropham which prevents sprouting, and has been known to be slightly toxic for aquatic animals and honeybees. The U.S. Environmental Protection Agency classifies chlorpropham as “slightly toxic,“ meaning it can cause mild skin and eye irritation.
I am not sure why Sweet Potato 2 did so poorly other than it was not “certified organic” ~ just labeled as that. Obviously, the certified organic sweet potato won the race for cascading, healthy sweet potato vines! I will say I go along with the “dirty dozen” advice so do always buy my potatoes organic. I also am aware that even organic produce needs to be washed thoroughly before eating!
Here is the video ~ enjoy!
