Menej m\u00e4sa, viac rastlinn\u00fdch potrav\u00edn a mal\u00e9 mno\u017estvo jednej konkr\u00e9tnej aminokyseliny.

Vedci sa nezamerali iba na mno\u017estvo bielkov\u00edn, no v\u00e4\u010d\u0161iu pozornos\u0165 venovali ich zlo\u017eeniu. Hlavn\u00fa \u00falohu zohrala aminokyselina metion\u00edn, ktor\u00fa n\u00e1jde\u0161 najm\u00e4 vo vajciach, m\u00e4se a mlie\u010dnych v\u00fdrobkoch. Organizmus ju potrebuje, no pod\u013ea autorov v\u00fdskumu zohralo ve\u013ek\u00fa \u00falohu pr\u00e1ve spr\u00e1vne mno\u017estvo.<\/p>\n

Ved\u00faci v\u00fdskumu Valter Longo sa tejto t\u00e9me venoval u\u017e dlh\u00e9 roky. In\u0161piroval sa tradi\u010dnou stredomorskou stravou, ktor\u00e1 pomohla obyvate\u013eom niektor\u00fdch oblast\u00ed ju\u017enej Eur\u00f3py dosiahnu\u0165 vysok\u00fd vek.

Preto vytvoril upraven\u00fa verziu takzvanej dlhovekostnej di\u00e9ty. T\u00e1 stavila najm\u00e4 na rastlinn\u00e9 potraviny, doplnila ryby a obsahovala ni\u017e\u0161\u00ed podiel bielkov\u00edn. Vedci k nej pridali mal\u00e9 mno\u017estvo metion\u00ednu, aby organizmus netrpel jeho nedostatkom. N\u00e1sledne rozdelili star\u0161ie my\u0161i do \u0161tyroch skup\u00edn. Jedna prij\u00edmala be\u017en\u00fa stravu, druh\u00e1 z\u00e1padn\u00fd jed\u00e1lni\u010dek s vysok\u00fdm obsahom cukru a tukov, tretia ketog\u00e9nnu di\u00e9tu s n\u00edzkym obsahom sacharidov a posledn\u00e1 nov\u00fa dlhovekostn\u00fa di\u00e9tu.<\/p>\n

Pr\u00e1ve posledn\u00e1 skupina dosiahla najlep\u0161ie v\u00fdsledky. My\u0161i \u017eili dlh\u0161ie v dobrom zdravotnom stave, stratili \u010das\u0165 telesn\u00e9ho tuku a vyk\u00e1zali ni\u017e\u0161iu mieru krehkosti. Z\u00e1rove\u0148 si zachovali svalov\u00fa hmotu.<\/p>\n

\u201eO\u010dak\u00e1vali sme rozdiely medzi jednotliv\u00fdmi di\u00e9tami, no najviac n\u00e1s prekvapilo, \u017ee \u00faprava jedinej aminokyseliny, metion\u00ednu, vyvolala tak\u00e9 v\u00fdrazn\u00e9 metabolick\u00e9 zmeny,\u201c vysvetlila autorka \u0161t\u00fadie, Maura Fanti.<\/p>\n

Vedci z\u00e1rove\u0148 sledovali viacero biologick\u00fdch ukazovate\u013eov. U my\u0161\u00ed na novej di\u00e9te namerali vy\u0161\u0161ie hladiny horm\u00f3nov, ktor\u00e9 s\u00faviseli s metabolizmom a procesmi starnutia<\/a>. Medzi nimi sa objavil aj horm\u00f3n GLP-1, ktor\u00fd zohr\u00e1va d\u00f4le\u017eit\u00fa \u00falohu pri regul\u00e1cii hladiny cukru v krvi a stal sa z\u00e1kladom viacer\u00fdch modern\u00fdch liekov na cukrovku<\/a> \u010di chudnutie.<\/p>\n

Autori v\u0161ak upozornili, \u017ee v\u00fdsledky z my\u0161\u00ed nemo\u017eno automaticky prenies\u0165 na \u010dloveka. \u013dudsk\u00fd organizmus funguje zlo\u017eitej\u0161ie a klinick\u00e9 sk\u00fa\u0161ky e\u0161te len pr\u00eddu.<\/p>\n

Zauj\u00edmav\u00e9 poznatky priniesla aj anal\u00fdza \u00fadajov od viac ako 200-tis\u00edc \u013eud\u00ed. Vedci porovnali ich stravovanie so zdravotn\u00fdm stavom. Uk\u00e1zalo sa, \u017ee \u00fa\u010dastn\u00edci s najvy\u0161\u0161\u00edm pr\u00edjmom \u017eivo\u010d\u00ed\u0161nych bielkov\u00edn \u010dastej\u0161ie trpeli obezitou a cukrovkou 2. typu. Riziko cukrovky dosiahlo pribli\u017ene dvojn\u00e1sobok oproti \u013eu\u010fom, ktor\u00ed prij\u00edmali len mal\u00e9 mno\u017estvo \u017eivo\u010d\u00ed\u0161nych potrav\u00edn alebo sa im \u00faplne vyhli.<\/p>\n

Prekvapenie priniesol e\u0161te jeden detail. Skupina s vy\u0161\u0161\u00edm pr\u00edjmom m\u00e4sa prij\u00edmala menej kal\u00f3ri\u00ed a celkovo dodr\u017eiavala zdrav\u0161\u00ed jed\u00e1lni\u010dek. Napriek tomu nedosiahla lep\u0161ie v\u00fdsledky. Valter Longo, preto upozornil, \u017ee samotn\u00e9 po\u010d\u00edtanie kal\u00f3ri\u00ed nemus\u00ed rozhodn\u00fa\u0165 o \u00faspechu<\/p>\n

\u201eTieto v\u00fdsledky spochybnili predstavu, \u017ee na chudnutie sta\u010d\u00ed iba obmedzi\u0165 kal\u00f3rie. Nazna\u010dili tie\u017e, \u017ee mus\u00edme lep\u0161ie pochopi\u0165 mechanizmy, ktor\u00e9 za t\u00fdm stoja,\u201c povedal.<\/p>\n

Vedci z\u00e1rove\u0148 objavili ve\u013emi d\u00f4le\u017eit\u00fa hranicu. Pr\u00edli\u0161 n\u00edzky pr\u00edjem metion\u00ednu organizmu neprospel. My\u0161i za\u010dali vykazova\u0165 zn\u00e1mky krehkosti, naopak, pr\u00edli\u0161 vysok\u00fd pr\u00edjem v\u00fdhody celej di\u00e9ty prakticky zru\u0161il. Zd\u00e1 sa teda, \u017ee rozhodla spr\u00e1vna rovnov\u00e1ha.<\/p>\n

Pr\u00e1ve tento poznatok m\u00f4\u017ee vysvetli\u0165, pre\u010do nesta\u010d\u00ed sledova\u0165 iba celkov\u00e9 mno\u017estvo bielkov\u00edn. Ove\u013ea v\u00e4\u010d\u0161iu \u00falohu m\u00f4\u017ee zohr\u00e1va\u0165 ich konkr\u00e9tne zlo\u017eenie.<\/p>\n
