Pistachio nuts from Aegina are among the highest in nutrition and the lowest in calories in the wider category of nuts. They are pretty high in protein, dietary fibers and very rich in various vitamins. Furthermore, they are rich in antioxidants and their consumption can reduce cholesterol levels.
Prefer the raw kernel type when you want the highest level in nutrition terms (add them in your breakfast milk/yoghurt bowl or in your fruit salads), however you can try them also in every sweet recipe you can imagine.
