Kwayoyin Halitta, epigenetics, da kuma "gado" na haɗarin kiba
Ɗaya daga cikin manyan gudummawar da aka bayar wajen maganin halittu shine gano rawar da kwayoyin halitta ke takawa. Nazarin haɗin gwiwar kwayoyin halitta (GWAS) ya gano bambance-bambancen kwayoyin halitta da yawa da ke da alaƙa da ma'aunin yawan kitse a jiki (BMI) da kuma rarraba kitse.

Matsayin ƙwayoyin cuta na hanji a cikin metabolism
Kwayoyin halittar hanji—tarin ƙwayoyin halitta da ke rayuwa a cikin hanyar narkewar abinci—yana ɗaya daga cikin batutuwa mafi ban sha'awa a cikin binciken kiba na biomedical. Tsarin ƙwayoyin halittar hanji yana da alaƙa da ingancin shan kuzari daga abinci, samar da metabolites kamar gajerun kitse mai (SCFAs), da kuma daidaita tsarin garkuwar jiki.
