Ngokweminyaka yobudala, umphumela wasebekhulile ngokuvamile ungcono kunentsha; Kusukela endaweni yezempilo, abantu abagulayo badla umphumela we-peptide. Umuntu onempilo. Mayelana nokukhathala, abantu abakhathele benza kangcono kunabanye; Abantu abahlinzwe benza kangcono ngama-peptide kunabantu abangazange bahlinzwe... Ngoba ama-peptide anenani eliphezulu lokudla okunomsoco, kulula ukumunca, anciphisa umthwalo womgudu wokugaya ukudla, akhuthaze ukuphulukiswa kwesilonda kanye nezici zokulwa nokukhathala, ngakho-ke kuwumphumela wokuphulukisa amanxeba. okufanayo nomuthi ofanele, lapho abantu besesimweni sokuphila, badinga ama-peptide anemisebenzi ehlukene ukuze agcwalise.
