Dr Oz: Dark Side of Kale
Dr Oz loves Kale, and he has featured it on the show many times. But he said that sometimes there can be too much of a good thing. Learn how Goitrin can cause Hypothyroidism and whether to worry about Kidney Stones.
Kale has more iron than beef and more calcium than milk. It is also loaded with antioxidants and lowers cholesterol while reducing your risk of heart disease and cancer. Kale has grown 150% in popularity over the past five years.
Dr Oz: Too Much Kale?
However, now experts are worried that too much Kale can be bad for you. Audience member Christy said she loves making Kale Chips with her son, five-year-old Tyler. The family also uses Kale in salad or smoothies. There are plenty of great ways to prepare the veggie.
Christy said she has occasionally noticed gas or bloating when she overdoes it. Kale is in the same cruciferous family as broccoli and cauliflower, but Dr Oz said there are some health side effects we should know about.
Kale could be linked to Hypothyroidism, which means it could be slowing the Thyroid down. Christy investigated a Thyroid, which was small, rubbery, and butterfly-shaped. This small gland can grow when a substance in Kale sometimes blocks hormone release. Symptoms can include weight gain, fatigue, and hair loss.
Dr Oz: Kale Goitrin Vs Seaweed Iodine
Dr Oz said that the best solution to protect your Thyroid is to make sure Kale is cooked. It only needs to be done for a couple minutes to reduce the amount of Goitrin present in the vegetable, which is what can interfere with the Thyroid.
Another option, if you prefer eating raw Kale, is to combine it with Seaweed, which is high in Iodine, which can balance the effects of Kale on the Thyroid.
Dr Oz: Kidney Stones from Kale?
The kidneys are an amazing organ located behind your ribs. Dr Oz said another concern about Kale can be Kidney Stones, which can camp out in the ureter that drains the Kidneys. Those who have had Kidney Stones know they are very painful.
Oxalates are a mineral that come from foods, including Kale. These minerals can form those unwanted stones. Alternate servings of Kale with greens that have lower oxalate levels, such as Bok Choy, Mustard Greens, Collard Greens, and Arugula. (If you don’t have a family history of Kidney Stones, you may not have to worry at all.)
Dr Oz: Kale Vs Antibiotics & Blood Thinners
Finally, Dr Oz warned that Kale could interfere with antibiotics or blood thinner medications. The Vitamin K content of the vegetable can disrupt the way the medicine works. Here again, you can alternate with vegetables that contain lower levels of Vitamin K, including Asparagus, Green Beans, Cabbage, Peas, and Romaine Lettuce.
