We all love some kale. I'm a serious fan of kale chips, myself. It is full of so many wonderful vitamins and nutrients but might it be full of something else too? Recent studies by molecular biologist Ernie Hubbard, found that kale also contains heavy metals! Kale, a well as cabbage, broccoli, cauliflower, and collard greens, were found to be hyper accumulators of heavy metals like thallium and cesium. They also found traces of nickel, lead, cadmium, aluminum, and arsenic were common in greens both organic and non. How is this happening? It's the soil. "If it's left in the ground, the leafy greens are going to take it up," Hubbard told Craftsmanship Magazine. Thallium is a common ingredient in rat poison. The people who tested positive for the metal hadn't consumed enough for it to be poisonous but it did cause them fatigue, heart arrhythmia, nausea, digestive trouble, neurological problems, and hair loss. The worst part is that even after a detox, the metal still appeared in their system. Yes, there are toxins everywhere in our lives but there is reason to be concerned here. We now know that heavy metals are additive and synergistic," says David Quid, the lead scientist at Doctors Data, who has an PhD in nutritional biochemistry. "If you get a little thallium, and a little lead, and a little cadmium in your system, you've got one plus one plus one equals five or six, not just three." Basically, they are worse when combined. "This stuff bioaccumulates," he added. "Down the road, it's going to kick you in the ass one way or another." Okay, so no point freaking out just yet but definitely time to take it easy on those greens... Does is this news make you nervous?
