Kufufuza kwa kafukufuku waposachedwapa asanu, kuphatikizapo milandu yoposa 76000, kunasonyeza kuti imfa ya matenda a mtima wamtima inali 31% yotsika pakati pa amuna osadya zamasamba poyerekeza ndi osadya zamasamba, ndipo 20% yotsika pakati pa akazi. Pakafukufuku wokhawo pankhaniyi, yemwe adachitika pakati paodya nyama zakutchire, chiwopsezo chotenga matendawa chinali chochepa kwambiri pakati pa amuna osadya nyama kuposa amuna omwe amadya zamasamba.
Chiŵerengero cha imfa chinalinso chocheperapo pakati pa odya zamasamba, amuna ndi akazi, poyerekeza ndi osadya zamasamba; amene amadya nsomba zokha, kapena amene amadya nyama zosaposa kamodzi pa sabata.
Kuchepa kwa matenda amtima pakati pa omwe amadya masamba ndi chifukwa cha kuchepa kwa cholesterol m'magazi awo. Kuwunikanso kwa kafukufuku 9 kunapeza kuti odya zamasamba ndi ma vegans a lacto-ovo anali ndi 14% ndi 35% kutsitsa cholesterol m'magazi kuposa osadya zamasamba amsinkhu womwewo, motsatana. Ikhozanso kufotokoza za mlozera wapansi wa thupi pakati pa osadya.
Pulofesa Sacks ndi anzake adapeza kuti pamene mutu wa zamasamba unali wolemera kuposa wosadya zamasamba, mu plasma yake munali ma lipoprotein ochepa kwambiri. Kafukufuku wina, koma osati onse, akuwonetsa kuchepa kwa magazi a high molecular density lipoprotein (HDL) pakati pa osadya masamba. Kutsika kwa HDL kungayambitsidwe ndi kuchepa kwamafuta m'zakudya komanso kumwa mowa. Izi zingathandize kufotokoza kusiyana kochepa kwa chiwerengero cha matenda a mtima pakati pa amayi omwe ali ndi zamasamba komanso osadya zamasamba, monga High-density lipoprotein (HDL) m'magazi angakhale chiopsezo chachikulu cha matenda kusiyana ndi otsika-molecular-density lipoprotein (LDL). milingo.

Zinthu zingapo zokhudzana ndi zakudya zamasamba zimatha kukhudza kuchuluka kwa cholesterol m'magazi. Ngakhale kuti kafukufuku amasonyeza kuti anthu ambiri odyetsera zamasamba satsatira zakudya zamafuta ochepa, mafuta okhuta kwambiri pakati pa anthu osadya zamasamba ndi ochepa kwambiri kuposa omwe sadya zamasamba, ndipo chiŵerengero cha mafuta osakhutitsidwa ndi mafuta okhuta chimakhalanso chokwera kwambiri pazamasamba.
Odya zamasamba amakhalanso ndi cholesterol yocheperako kuposa osadya zamasamba, ngakhale kuti chiwerengerochi chimasiyana m'magulu omwe maphunziro adachitika.
Odya zamasamba amadya 50% kapena ulusi wambiri kuposa osadya masamba, ndipo zamasamba zimakhala ndi fiber zambiri kuposa ovo-lacto vegetarian. Ma soluble biofibers amatha kuchepetsa chiwopsezo cha matenda amtima pochepetsa kuchuluka kwa cholesterol m'magazi.
Kafukufuku wina akuwonetsa kuti mapuloteni a nyama amalumikizidwa mwachindunji ndi kuchuluka kwa cholesterol m'magazi.ngakhale zinthu zina zonse zopatsa thanzi zimayendetsedwa bwino. Odya zamasamba a Lacto-ovo amadya zomanga thupi zochepa kuposa omwe sadya zamasamba, ndipo zamasamba sizidya mapuloteni anyama konse.
