Dieticheskiy kokteyl dlya sna i stressa: chto govorit nauka
Dieticheskiy kokteyl chasto prodvigayetsya kak sredstvo dlya upravleniya vesom, no vsyo bolshe lyudey tyanutsya k nemu vecherom nadeyas, chto on takzhe uspokoyt nervnuyu sistemu i podderzhit son. Ideya imeet nauchnoe obosnovanie - to, chto vy yedite za neskolko chasov do sna, zametno vliyayet na arkhitekturu sna i stressovyy gormon kortizol. Eto rukovodstvo rasskazyvaet o mekhanizmakh, rassmatrivayet klinicheskiye dokazatelstva i dayot realistichnoye predstavleniye o tom, chto dieticheskiy kokteyl dlya sna i stressa mozhet i ne mozhet sdelat.
Pochemu makronutriyenty i son svyazany
Kachestvo sna chastichno reguliruyetsya neytrotransmitterami - prezhde vsego serotoninom i melatoninom. Oba sinteziruryutsya iz aminokisloty triptofan, kotoruyu neobkhodimo poluchat iz pishchi. Soderzhashchiye belok dieticheskiye kokteyli dostavlyayut triptofan, no kolichestvo, dostigayushcheye mozga, zavisit ot konkuriruyushchikh krupnykh neytralnych aminokislot i sootnosheniया prisutstvuyushchikh uglevodov.
Sovmestnoye pogloshcheniye uglevodov vyzyvayet insulin, kotoryy ochishchayet krov ot konkuriruyushchikh aminokislot, effektivno povyshaya transport triptofana v mozg (Markus et al., 2005). Etot biokhimicheskiy put - odna iz prichin, pochemu sbalansirovannyy dieticheskiy kokteyl - soderzhashchiy kak belok, tak i uglevody - mozhet byt bolee podderzhivayushchim rasslableniye, chem chistyy belkovyy izolyat prinyatyy odnostoronniy.
Stress svyazan s kortizolom, kotoryy dostigayet pika rannim utrom i dolzhen snizhat'sya v techenie dnya. Vechernee pogloshcheniye belka mozhet smyagchit reaktivnost kortisoola stressa, stabilizuruya uroven glyukozy v krovi noch'yu, umenshenya metabolicheskiy stress, kotoryy inache vyzyvayet vybrosy kortizola (Maki et al., 2012).
Chto na samom dele pokazyvayut RCT-dokazatelstva
Pryamykh RCT, testiruyushchikh dieticheskiye kokteyli na pokazateli sna, malo. Bolshaya chast dokazatelstv proiskhodit iz issledovaniy otdelnykh ingrediyentov, obychno vstrechayushchikhsya v kokteylakh - syvorotochny belok, kazein ili spetsificheskiye uglevodnyye smesi.
Randomizirovannoe perekrestnoye issledovaniye obnaruzhilo, chto gidralizat syvorotochnogo belka, obogashchennyy alfa-laktalbuminom (fraktsiya s vysokim soderzhaniem triptofana), uluchshil subyektivnoye kachestvo sna po sravneniyu s kontrolem kazeina u zdorovykh vzroslykh v usloviyakh legkogo stressa (Markus et al., 2005). Effekt byl svyazan s povyshennym sootnosheniem triptofana plazmy k krupnym neytralnym aminokislotam.
Kazeinovy belok, poskol'ku on perevarivayetsya medlenno v techenie neskolkikh chasov, pokazal podderzhku nochnogo sinteza mышechnogo belka i mozhet sposobstvovat bolee stabilnomu urovnyu glyukozy v krovi, kotoryy svyazan s men'shim kolichestvom nochnykh probuzhdeny (Res et al., 2012). Produkty kak OstroVit Vegan Meal Shake 1000g Cappuccino i OstroVit Beauty Blend for Shape 360g Kreemjas maasikas obespechivayut smeshanny makroprofile, kotoryy mozhet podderzhivat etot effekt.
Otnositelno stressa issledovaniya u zdorovykh vzroslykh predpolagayut, chto dobavki syvorotochnogo belka svyazany s bolee nizkimi otsenkami subektivnogo stressa v techenie neskol'kikh nedel (Markus et al., 2005). Mekhanizm, veroyatno, svyazan s tem zhe putem triptofana, a ne s kakim-libo pryamym snizhayushchim kortizol farmakologicheskim deystviyem.
Effektivnaya doza i vremya priyema
Klyuchevye prakticheskie soobrazheniya:
- Doza: V bolshinstve polozhitelnykh issledovaniy ispolzovalos 20-30 g belka na porsyu. Porsii po etikete produkta SELF Whey Shake 1kg Vanill i SELF Whey Shake 1kg Sokolaad popadayut tochno v etot diapazon.
- Vremya priyema: Za 30-60 minut do sna kazhetsya optimalnym dlya oblegcheniya transporta triptofana i dlya nachala deystviya medlenno perevarivayushchikhsya belkov v techenie nochi.
- Sovmestnoye pogloshcheniye uglevodov: Nebolshoye kolichestvo uglevodov (10-20 g) vmeste s belkom uluchshayet pogloshcheniye triptofana. Mnogie zameniteli pitaniya uzhe vklyuchayut eto sootnosheniye.
- Kontekst kalorey: Kokteyl pered snom dobavlyayet kaloriy. Yesli vasha tsel - upravleniye vesom, uchityvay eti kaloriy v dnevnykh znacheniyakh, a ne rassmatrivay vecherniy kokteyl kak dobavku.
Kto, vsego veroyatnee, vyigrayet
Dokazatelstva naibolee ubeditelny dlya:
- Lyudey, kotorye nedoyedayut belok v techenie dnya i ispytyvayut ploye kachestvo sna kak sledstviye.
- Lyudey, nakhodnyashchikhsya pod legkoy ili umerennoy psikhologicheskoy nagruzkoy, u kotorykh mozhet byt narushen dostup k triptofanu.
- Sportsmenov ili aktivnykh lyudey, u kotorykh povyshenny potrebnosti v myshechnom belke i kotorye vygodayut ot nochnoy dostavki belka.
Dokazatelstva slabee ili otsutstvuyut dlya tekh, u kogo est klinicheskaya bessontsa, diagnostirovannyye trevozhnye rasstroystva ili znachitelno povyshennyy kortizol ot khronicheskogo stressa. V tekh sluchayakh dieticheskiye kokteyli ne zamenyayut nadlezhashchuyu meditsinskuyu pomoshch.
Chestnyy vyvod
Dieticheskiy kokteyl - ne snotvornoe. Polza dlya sna i stressa umerennaya, kosvennaya i luchshe vsego ponimaetsya kak optimizatsiya pitaniya, a ne farmakologiya. Yesli vash ratsion uzhe dostatochno bogat belkom, a stress preimushshestvenno psikhologicheskiy, vy ne uvidite sushchestvennykh izmeneniy ot dobavleniya kokteylya pered snom.
Vmeste s tem, dlya lyudey, kotorye privychno propuskayut vecherniy belok, khorosho sformulirovannyy dieticheskiy kokteyl so smeshannym makroprofilem - razumnyy instrument, obosnovannyy dokazatelstvami.
