I overheard someone talking to her friends about an article in a health magazine that said Kale was toxic. They were concerned because they had all been juicing kale daily to improve their health.
Ever since kale became the faddish superfood, people have been eating high amounts of it assuming it would make them extra healthy. More is better….right? The answer is “NO”.
The most recent study that’s gone viral is a report of people who eat kale taking in toxic levels of heavy metals, the worst of which is called thallium. They even threw out lead and arsenic as a concern. Heavy metal thallium toxicity, according to the study, causes fatigue, digestive issues, neurological issues, and skin and hair problems. Metals like this are found naturally in the soil just like all the minerals we like to take supplements for, including iron of which are necessary nutrients for the human body.
Keep in mind this was one study and there is not a lot of supporting documentation to justify such broad claims. This should, however, make you think about how much kale you are actually eating.
Besides the heavy metal issue, past studies found eating too many cruciferous vegetables can result in Hypothyroidism. Kale is part of the cruciferous family along with broccoli, cauliflower, cabbage and brussel sprouts. Goitrin seems to be culprit but there are others that also have the same effect.
Vitamins and minerals are essential to a healthy body. They are found in the soil and are taken up by the plants that you eat. You can’t live without them. Different plants draw up different compounds and you take those in when you eat them. The key is to eat everything in moderation and have a wide variety of foods. This will minimize your risk of toxic buildup of any one item.
If you enjoy your kale and aren’t diagnosed with toxicity, don’t stop eating it. Watch how much kale you are you taking in and maybe expand your horizons. There are many other healthy greens you can buy that are not only good for you, they may bring another mineral to the table that aren’t getting in and will improve your health even more!
