Gıdalardaki Karotenoidler ve İnsan Sağlığına Etkileri

Gıdalardaki kırmızı, turuncu ve sarı renklerden sorumlu olan karotenoidler, meyvelerde ve sebzelerde doğal olarak bulunan renk pigment ailesinin bir kısmını oluşturmaktadır. Diyetlerle alınan ve insan kanı serumunda bulunan temel 6 karotenoid şunlardır; β- ve α-karoten, likopen, lutein, zeaksantin ve β-kriptoksantin. Birçok çalışmada karotenoidlerin belirli kanser tipleri, kalp-damar, göz hastalıkları; özellikle de makula dejenerasyonu ve katarakt gibi hastalıklar üzerine olumlu etkilerinin olduğu ileri sürülmektedir. Karotenoidlerin antioksidan özelliklerinin de insan sağlığı üzerine yararlı etki sağladığı düşünülmektedir. İnsan organizması karotenoidleri sentezleyememekte, bu nedenle diyetlerle birlikte alınması gerekmektedir. Ana karotenoid kaynakları havuç, yeşil yapraklı sebzeler, domates, tatlı patates, yumurta ve mısırdır

Carotenoids in Foods and their Effects on Human Health

Carotenoids, responsible for the red, orange and yellow color in foods, consist a part of the pigment family that naturally present in vegetables and fruits. Six main carotenoids found in human blood serum and taken with the diet are β- and α-carotenes, lycopene, lutein, zeaxanthin, and β–cryptoxanthin. Many studies suggest that carotenoids have a positive effect on several diseases such as certain type of cancers, cardiovascular and ocular diseases, especially age related macular degeneration and cataract. The antioxidant properties of carotenoids may be responsible for their beneficial influence on human health. Human organisms are unable to synthesize carotenoids, therefore these compounds have to be supplied with the diet. Main carotenoid sources include carrots, green leafy vegetables, tomatoes, sweet potatoes, egg yolk and corn. In this study, carotenoids in foods and their effects on human health are reviewed
