Rhubarb is also a good source of lutein, a compound that has many health benefits. Include plenty of lutein in your diet is a healthy way to take care of your skin and eyes.
Lutein helps neutralize free radicals, which are dangerous compounds that can lead to cancer. It has been suggested that 1-cup serving of rhubarb contains 207 mcg of lutein.
