My annual Urban Crawl is coming up, my twelfth, on Friday, December 23rd in Winter Park.

My Urban Crawl is a free class. We meet in front of Panera’s at 10 a.m. We wander south to the college, stop at Starbucks, go east to the public library area, then back to Panera’s. It is wheelchair friendly.

BEGINNING POINT: Panera’s in Winter Park where we start and finish the Urban Crawl.

“A reasonable question is what about foraging in a city? There is some surprising research. Dan Brabaner is a geoscience professor at Wellesley College, Boston. With some undergraduate students they studied preserved food collected from fruit trees and the like in the urban Boston area. What they found was cherries, apples, peaches and herbs were relatively low in lead and arsenic. That is, a serving had less amounts of these toxins than the allowed daily amount for a child. The team also did not find a significant difference between peeled and unpeeled fruit. The fruit was low in toxic chemical because they are the furthest away from any toxins in the soil. This would apply to tree nuts as well. Leafy greens faired well, too, because they grow fast and 1) don’t have time to accumulate toxins and 2) most air pollution on them can be washed off. Brabander also analyzed foraged food from plants growing in the urban environment not growing on agricultural soil. These foods had higher micronutrients because they were not growing on worn-out agricultural soil. Calcium and iron were higher as were manganese, zinc, magnesium and potassium. Thus we know that not only do “weeds” pack more of a nutritional punch because they are wild but also because they can be growing in better soil.”
