Fonksiyonel bir gıda: Ceviz

Ceviz, yüksek oranda yağ ve protein içerdiğinden besleyici değeri oldukça yüksektir. Ceviz yağının en önemli özelliği ise doymamış yağ asitlerince oldukça zengin olmasıdır. Ceviz yağında linoleik asidin fazla olması cevizi eşi bulunmaz bir gıda yapmaktadır. Ayrıca bileşiminde yer alan biyolojik kalitesi yüksek protein, vitamin ve mineraller besleyici değerini arttırmaktadır. Son epidemiolojik çalışmalar, ceviz tüketiminin kardiyovasküler ölümleri azatlığını göstermektedir. Cevizin bu özelliğinin içerdiği polifenollerin antioksidan özelliğinden kaynaklandığı ifade edilmektedir.

Functional food: Walnut

Due to high protein and fat content walnut is very nutritive. The most important characteristic of walnut oil is the abundance of unsaturated fatty acids, which makes it a unique food because of high amount of linoleic acid. In addition, the protein, vitamins and minerals present enhance the biological and nourishing value. Recent epidemiological studies have associated walnut consumption with a reduced incidence of cardiovascular mortality, considering as the antioxidant properties of polyphenols.
