May reduce risk of heart diseases

One of many kale superpowers is the ability to bind bile acids in the digestive system. Now you probably wonder what bile acids are. So, here’s the explanation. Cholesterol makes bile acids and they help your body to digest fats. 

More precisely, your liver turns cholesterol into bile acids. Then, when your body has finished with fat absorption, those little bile acids get reabsorbed into the bloodstream and then used all over again. 

But, there are also substances known as bile acid sequestrants and they prevent bile acids to be reabsorbed. And here kale comes in.

It contains those sequestrants and that’s why kale can lower cholesterol in your body. All of that can potentially lead to a lower risk of heart diseases. 

One study shows that if a person drinks kale juice every day for 12 weeks can increase their body’s HDL or the “good” cholesterol by 27%. The study also found that LDL levels were lowered by 10%.

There is also one more awesome thing. One study showed that steamed kale increases the bile acid-binding effect greatly. Therefore, it turned out kale has similar potency as a cholesterol-lowering drug.
