Kale is famous for being one of the world's healthiest foods. Kale is a crucial part of almost every green smoothie, either as a main or additional ingredient. Experts recommend that people should consume kale on at least a weekly basis. They vouch that kale can fit into any diet and that it will make a major improvement in one's health. This makes people wonder, is kale really that good? Is a food this healthy a hoax or the real thing?


1. Vision Improvement

The macula is a small part of the retina that allows us to have three-dimensional vision. Every second, this minuscule organ takes oxidative damage by simply touching oxygen. There are also the high-energy blue light photons that scientists claim can make our eyes more vulnerable. Eye pigmentation, macula improvement, and overall vision enhancement are all directly related to the intake of lutein, which kale contains more than any other food. Scientists theorize that lutein can also allow us to detect polarized light, which is a phenomenon of the human eye.
