Abstract

Promjena načina prehrane treba se temeljiti na smanjenju unosa masti, posebno zasićenih masnih kiselina i kolesterola, uz relativno povećanje unosa nezasićenih masnih kiselina. Ulja, ovisno o podrijetlu i načinu priprave, imaju različite učinke na serumske lipoproteine. Ispitivanja su pokazala da utjecaj pojedinog ulja na koncentraciju LDL i HDL-kolesterola ovisi o postotku sadržaja pojedinih masnih kiselina. Sastav masnih kiselina u ulju avokada i brojnost antioksidansa, sugerira korištenje ovog ulja u preventivne svrhe protiv nekih patoloških stanja kao što su kardiovaskularne bolesti. U ovom radu je uspoređen utjecaj prehrane sa povećanim udjelom mononezasićenih masnih kiselina (ulje avokada) na faktor rizika za razvoj kardiovaskularnih bolesti. Prehrana sa povećanim udjelom mononezasićenih masnih kiselina snizila je aterogeni indeks za 65,6%, u odnosu na kontrolnu grupu. Na osnovu rezultata prikazanih u ovom radu može se zaključiti da je dodatak ispitivanog ulja u prehrani bolji nego prehrana bazirana na niskom sadržaju masnoća u prehrani zbog povoljnijeg utjecaja na profil lipida u krvi i faktore rizika za razvoj kardiovaskularnih bolesti.

Abstract (english)

The dietary changes should be based on reducing total fat, especially saturated fat and cholesterol, and with relative increase of intaking unsaturated fats. Oils, depending on the origin and methods of preparation, have different effects on serum lipoproteins. Trials have shown that the effects of a particular oil LDL and HDL-cholesterol depends on the percentage of the content of individual fatty acids. Virgin avocado oil is of a great interest regarding the research on cardiovascular risk prevention due to its fat composition and antioxidant compounds.In the present study, it has been shown that a high-MUFA diet (with avocado oil) has a significant influence on decreasing the CVD risk. So,the most significant difference between the two groups compared in this study, was that the atherogenic index in groups in which avocado oil was added, was significantly lower (for approximately 65.6%) than atherogenic index recorded in the control group. Collectively, these findings point to the fact that a high MUFA diet may be preferable to a low-fat diet due to its more favorable effects on the CVD risk profile.
