Kale joins the "Dirty-Dozen' list: and How to Grow Your Own Kale

Kale - a generous plant!
Every year, the Environmental Working Group publishes the findings of their analysis of concentrations of farm-chemicals in popular produce. This CNN article goes into more detail about this year's study. Unfortunately, kale and collards - two of the most nutrient-dense foods available, have made it onto the list again.
 
Below is a  a re-post of an article we published back in 2019 with other useful links on the topic of farm chemicals in food and some tips on growing your own garden-greens. If you're local and have some garden-space to add some kale, chard or collards, let us know soon so we can start some "starts" for you.

The re-post:
In recent weeks (April 2019) we've seen several headlines announcing that kale has made it onto the "Dirty Dozen" list for the first time in ten years.  The "Dirty Dozen" list is compiled each year by testing thousands of samples of fruits and vegetables from different sources to see which have highest concentrations of herbicides and pesticides LINK. And the farm chemicals are not just showing up on the vegetables themselves, studies have shown that, people being tested have increasingly been found to have these chemicals show up in fluid samples such as blood and urine (see links below). 
 
It is unfortunate that kale has returned to the "Dirty Dozen" list as, in the past few years, it has shown a surge in popularity. Its recent following is not surprising as it tastes similar to broccoli and it is at the top of another list - The Aggregate Nutrient Density Index (ANDI), that rates foods by their nutrient density. Kale (and collards) have the densest concentration of nutrients, per calorie, of a wide range of foods tested. (PDF of 72 tested foods) (explanation of chart). On the positive side of things, people who have switched to an all-organic diet have been able to reduce these chemical residues by as much as 90% in as little as two weeks (see links below).

So, if you'd like to incorporate more organically grown kale into your diet  and you're on a budget (we've noticed that prices for organic kale have really risen in the past few years...) perhaps you'd like to try and grow your own!

Kale is very easy to grow! Here's our POST on growing kale.
Grow your own kale: Kale is super-easy to grow and 2-4 plants will easily keep a family fed over the course of the summer. If your climate isn't too harsh you can grow a second crop that will produce food through the fall and winter too (though at a much slower rate). Here's our POST on growing kale.
Home grown veggies, freshest and best!

How we grow our food at the Sharing Gardens: Because we are not a commercial farm, all our labor is provided by volunteers and we are under no pressure to produce food on a forced timeline to get it to market ahead of the other farmers in our area, our food is slow-grown, with less water-weight and hence more nutrient-dense. We fertilize primarily with compost derived from leaves, grass, weeds and food scraps, wood-ash from our wood-burning stove and with worm castings we harvest from the paths of our greenhouses LINK. We do not use commercial fertilizers. The wood-ash and the composted tree-leaves both provide re-mineralization of our soils because the tree-roots pull up minerals from deep within the soil. Without forcing our plants to grow fast with high-nitrogen fertilizers, or animal manures, they are more resistant to diseases and insect infestations that are caused, in part, by the thinner cell-walls of plants forced to grow unnaturally quickly.
