The sunflower kernel which is the edible heart of the sunflower seed, is
a good source of phytochemicals (non-nutrient plant chemicals) that can be
protective against disease.
In comparison to other nuts and foods sunflower
kernels contain high levels of vitamin E, betaine, phenolic acids, and choline.
In addition, the kernels are a good source of arginine and lignans compared
to other nuts. All these compounds are very important and have many health
benefits. Check out more information from the websites below.
