Abinci mai nauyi

Abinci mai nauyi shine amfani da abubuwan gina jiki wanda aka maye gurbin wasu atoms tare da isotopes masu nauyi marasa rediyo, kamar  (2H) ko (13C). Biomolecules waɗanda suka haɗa da isotopes masu nauyi suna haifar da tsarin kwayoyin da ya fi tsayayya a wasu yanayi, wanda aka yi la'akari da ƙara juriya ga lalacewar da ke da alaƙa da tsufa  ko cututtuka. 

Magunguna tare da wasu ƙwayoyin hydrogen da aka maye gurbin da deuterium ana kiransu magungunan deuterated, yayin da abubuwa masu mahimmanci za a iya amfani da su azaman kayan abinci, suna sa wannan abinci "isotopic". Idan aka ci tare da abinci, waɗannan abubuwan gina jiki sun zama kayan gini ga jiki. Misalan sune deuterated polyunsaturated fatty acids, aminoacids masu mahimmanci,  tushen DNA kamar cytosine,  ko Ruwa mai nauyi da glucose.
