San Diego, CA—Lovers of spicy jalapenos, habaneros and other chili peppers are in luck because a recent study found that they are heart-healthy foods. This report was part of the 243rd National Meeting and Exposition of the American Chemical Society. The focus was on capsaicin and capsaicinoids from peppers, which are common in joint- and pain-support creams. Now, Zhen-Yu Chen, Ph.D., and his team from the Chinese University of Hong Kong found that capsaicin and a chemical relative improve heart health in two different ways. First, they lower cholesterol levels by reducing cholesterol accumulation, followed by an increase in its breakdown and excretion. Second, they block the action of a gene that causes arteries to contract, which restricts blood flow to the heart. Chen’s team gave hamsters a high-cholesterol diet and divided them into groups, some receiving just food while others also received capsaicinoids. Overall, capsaicinoids reduced total cholesterol blood levels, lessened LDL cholesterol and kept HDL cholesterol the same. They found that capsaicinoids may reduce the size of deposits that have already formed in blood vessels, which can lead to heart attack or stroke. Published in WholeFoods Magazine, June 2012

Ljuta hrana je ključ za zdravo srce Aktivni sastojak u čiliju, feferonima te ostalim ljutim papričicama štiti srce smanjujući kolesterol i visoki krvni tlak Svi ljudi koji uživaju u dobro začinjenoj, odnosno ljutoj hrani čine sebi i svojem zdravlju ogromnu uslugu, a da toga nisu ni svjesni. Naime, znanstvenici su dokazali da kapsaicin, kemijski spoj koji daje ljutinu feferonima, čiliju i drugim ljutim papričicama, smanjuje razinu kolesterola u krvi te snižava visoki tlak. Kineska studija provedena je na način da su laboratorijski miševi podijeljeni u dvije skupine, kontrolnu i eksperimentalnu. Iako su obje grupe konzumirale hranu punu kolesterola, samo je eksperimentalna skupina glodavaca dobivala kapsaicin. Rezultati su pokazali da ljuta supstanca smanjuje razinu "lošeg" kolesterola tako što sprječava njegovu akumulaciju, ubrzava proces razgradnje izlučivanja iz organizma. Kapsaicin, također, blokira gen koji uzrokuje kontrakciju krvnih žila i na taj način one postaju prohodnije što automatski rezultira boljom cirkulacijom. "Ovo je prva studija koja dokazuje da kapsaicin pozitivno djeluje na niz faktora koji su krucijalni za zdravlje srca i krvnih žila", rekao je dr. Zhen-Yu Chen, profesor na Kineskom Sveučilištu u Hong Kongu i autor studije. Stoga, ako volite ljutu hranu i navikli ste na nju slobodno navalite, no ako ste "osjetljiviji" tip znanstvenici preporučaju umjereno doziranje koje odgovara vašem ukusu.
