20.500.12556/RUL-174488 Naravno prisotni hormoni v mleku in vpliv na potrošnike diplomsko delo Naturally occurring hormones in milk and impact on consumers B. Sc. thesis Biološki pomen mleka je zagotavljanje hranil in energije za novorojence, zato vsebuje številne snovi nujne za rast, razvoj in zaščito mladiča, vključno z majhnimi količinami različnih hormonov. Sestava kravjega mleka se zelo razlikuje med različnimi pasmami in tudi med različnimi stadiji laktacije. Sveže mleko sesalcev vsebuje maščobe, ogljikove hidrate, vitamine, beljakovine, rudninske snovi in vodo, pa tudi hormone. Najpomembnejši hormoni, ki jih lahko diagnosticiramo v mleku in drugih mlečnih izdelkih, so prolaktin in steroidni hormoni vključno z estrogeni, progesteronom, androgeni in kortikosteroidi. Poleg tega je prisotnost različnih hormonov, na primer insulinu podobnega rastnega faktorja-1 (IGF-1) in sorodnih hormonov ter prostaglandina (PG) potrjena tudi v mlečnih izdelkih. Ocenjuje se, da 60 do 80 % celotne zaužite količine hormonov s hrano pri ljudeh izvira iz mleka in mlečnih izdelkov. Prisotnost hormonov v mleku in mlečnih izdelkih pri potrošnikih vzbuja veliko zaskrbljenost in dvome zaradi morebitnih zdravstvenih posledic. Raziskave sicer kažejo, da imajo hormoni zanemarljiv biološki izkoristek in fiziološki učinek na ljudi, saj se v telesu večinoma razgradijo ali inaktivirajo. Po drugi strani pa nekatere objave nakazujejo, da bi ti hormoni lahko predstavljali zdravstveno tveganje za potrošnika. Namen tega diplomskega dela je, da s pomočjo znanstvene literature in kritične analize pridobljenih informacij preučimo najnovejša znanstvena dognanja o varnosti mleka in mlečnih izdelkov za zdravje ljudi, s poudarkom na vlogi hormonov. The biological significance of milk is to provide nutrients and energy for newborns, containing numerous substances essential for the growth, development, and protection of the young, including small amounts of various hormones. The composition of cow's milk varies greatly between different breeds and also between different stages of lactation. Fresh milk from mammals contains fats, carbohydrates, vitamins, proteins, minerals, and water, as well as hormones. The most important hormones that can be detected in milk and other dairy products are prolactin, steroid hormones including estrogens, progesterone, androgens, and corticosteroids. Additionally, the presence of various hormones such as insulin-like growth factor-1 (IGF-1) and related hormones, as well as prostaglandins (PG), has also been confirmed in dairy products. It is estimated that 60 to 80% of the total intake of hormones through food in humans comes from milk and dairy products. The presence of hormones in milk and dairy products raises significant concern and doubts among consumers due to potential health consequences. Research indicates that hormones have negligible bioavailability and physiological effects on humans, as they are mostly broken down or inactivated in the body. On the other hand, some publications suggest that these hormones could pose a health risk to consumers. The aim of this thesis is to examine the latest scientific findings on the safety of milk and dairy products for human health, with a focus on the role of hormones, through scientific literature and critical analysis of the obtained information. mleko hormoni potrošniki zdravstveno tveganje milk hormones consumers health risk true false false A.
