Abstract

Veganstvo je alternativna oblika prehranjevanja, za katerega je značilno, da se iz prehrane izključijo vsa živila živalskega izvora. Med posamezniki, ki so se, zaradi različnih motivov, odločili za veganski način prehranjevanja, so tudi rekreativni športniki. V raziskovalnem delu magistrske naloge smo po metodi tridnevnega prehranskega dnevnika ovrednotili kakovost jedilnikov veganov in vegank, ki se rekreativno ukvarjajo s športom in spadajo v starostno skupino 25-35 let. Pri tem nas je zanimalo, ali z veganskim načinom prehranjevanja zadostijo potrebam po beljakovinah in esencialnih aminokislinah. Jedilnike veganov in vegank, ki se rekreativno ukvarjajo s športom (skupina veganov), smo primerjali z jedilniki vsejedcev in vsejedk, ki se rekreativno ukvarjajo s športom (kontrolna skupina). Ugotovili smo, da je skupina veganov, z veganskim načinom prehranjevanja zaužila 1,30 g beljakovin/(kg TM·dan) in s tem ni zadostila priporočilom za vnos beljakovin za športnike vegane in športnice veganke (1,4-2,0 g beljakovin/(kg TM·dan)). Ob primerjavi jedilnikov skupine veganov, z jedilniki kontrolne skupine, smo ugotovili, da so vsi preiskovanci iz kontrolne skupine (N = 5) zadostili priporočilom za vnos beljakovin, pri veganih pa sta priporočilom zadostila samo dva vegana (N = 2) od petih (N = 5). Glede vnosa esencialnih aminokislin smo prišli do ugotovitev, da skupina veganov ni zadostila priporočilom za vsebnost lizina (45 mg/g beljakovin) in metionina (16 mg/g beljakovin) v gramu zaužitih beljakovin, saj so povprečno zaužili 44 mg lizina/g beljakovin in 14,1 mg metionina/g beljakovin. Kontrolna skupina je v primerjavi s skupino veganov, zaužila več histidina (p = 0,030), izolevcina (p = 0,037), levcina (p = 0,047), lizina (p = 0,00002), metinona + cisteina (p = 0,005), metionina (p = 0,00008) in treonina (p = 0,015) od svojega skupnega dnevnega vnosa beljakovin.

Secondary title: Protein intake by vegan diet in recreational athletes
Secondary abstract: Veganism is an alternative dietary practice where person is abstaining from the use of animal products, particularly in diet. Reasons for that differ. Among individuals, who practice vegan diet, we can also find recreational athletes. In the exploratory part of the master's thesis, vegans completed a three-day nutritional diary, with which we aimed to evaluate diets' quality. The experimental group included recreational athletes, aged between 25 and 35. The main question we wanted to answer was, if they fulfil their daily protein and essential amino acid needs. We compared food intake of recreational athletes (vegan group) with that of omnivores, who were also recreational athletes (control group). Vegan group consumed 1,30 g of protein/(kg BM·day), which did not satisfy daily requirements for protein consumption for recreational vegan athletes (1,4-2,0 g protein/(kg BM·day)). When we compared diets of both groups, we could see that all subjects of the control group (N = 5) met the recommendations for protein intake, in contrast to only two vegans (N = 2) out of five (N = 5) in the vegan group. With regards to essential amino acids, we came to the conclusion that vegan group did not satisfy recommended daily intake values for lysine (45 mg/g protein) and methionine (16 mg/g protein). In fact, they consumed 44 mg of lysine/g of protein and 14,1 mg of methionine/g of protein. Compared to vegan group, the control group consumed more histidine (p = 0,030), isoleucine (p = 0,037), leucine (p = 0,047), lysine (p = 0,00002), methionine + cysteine (p = 0,005), methionine (p = 0,00008), and threonine (p = 0,015) from their total daily protein intake.
