Marelice – vir kalija za zdravo srce in možgane

Marelice, rumeno-oranžni plodovi, ki dozorijo poleti so bogati z vitamini, minerali antioksidanti in vlakninami. Med minerali je še posebej izpostavljen kalij, ta tako pomemben mineral, ki ga telo nujno potrebuje za normalno delovanje.

Marelice izvirajo iz Kitajske, kjer so jo po nekaterih podatkih gojili že pred 4000 leti, v Sredozemlje so prišle pred približno 2000 leti. Danes sta Turčija in Iran največji svetovni proizvajalki marelic, rastejo pa tudi na slovenskih vrtovih.

Sveže marelice vsebujejo:

  • Vitamin A
  • Vitamin C
  • Pantotenska kislina (B5)
  • Vitamin E
  • Beta-karoten
  • Kalij
  • Lutein
  • Zeaksantin
  • Likopen
  • Cink
  • Baker
  • Železo
  • Fosfor
  • Mangan
  • Magnezij

Vse suho sadje vsebuje enake hranilne lastnosti kot originalno sveže sadje. Dejansko po masi posušena oblika vsebuje več antioksidantov, mineralov in vlaknin kot surovi sadež.

Visoka vsebnost kalija

Marelice vsebujejo veliko kalija, ki v telesu nadzoruje pravilno delovanje srca in možganov. Odgovoren je tudi za pošiljanje živčnih signalov in nadziranje krčenja mišic.

Dve marelici (70 gramov) zagotavljata 181 mg omenjenega minerala, kar je 4 % dnevnega vnosa (3.500 mg).

Ker kalij tesno sodeluje z natrijem pri vzdrževanju ravnovesja tekočin v telesu, lahko ustrezen vnos kalija prepreči tudi napihnjenost in vzdržuje zdrav krvni tlak.

Še druge koristi marelic za zdravje

Marelice so odličen vir vlaknin za boljšo prebavo. Netopne vlaknine povezujejo z zmanjšanjem tveganja za nastanek raka na črevesju. Topne vlaknine se združijo s holesterolom, preprečujejo njegovo absorpcijo in ga odnesejo iz telesa. Tri cele suhe marelice vsebujejo 5 g vlaken, kar je približno 20 odstotkov dnevne potrebe po vlakninah.

Marelice, bogate z vitaminom A, beta-karotenom in drugimi karotenoidi, odlično spodbujajo zdravje oči. Lutein pomaga pri ohranjanju zdravja mrežnice in leče, karotenoidi in vitamin E pa podpirajo splošno zdravje oči.

Marelice so dober vir flavonoidov in antioksidantov, ki ščitijo pred vnetji in vnetnimi boleznimi, hkrati pa zmanjšujejo tveganje za debelost, sladkorno bolezen in bolezni srca.

Antioksidanti (predvsem vitamin E in C), so znani po svojih lastnostih za zaščito kožnih celic pred UV sevanjem, zmanjšajo znake zgodnjih gub in izboljšajo elastičnost kože. Beta-karoten pa pomaga zaščititi kožo pred sončnimi opeklinami in dodatnimi UV-poškodbami. Ker imajo marelice visoko vsebnost vode, kožo tudi vlažijo.

This cookie is set once a visitor submits their information in the Recruit User Testers widget. It is used to ensure that the same form does not re-appear if it has already been filled in. 365 days _hjIncludedInSample Hotjar cookie. This session cookie is set to let Hotjar know whether that visitor is included in the sample which is used to generate funnels. 365 days _hjShownFeedbackMessage This cookie is set when a visitor minimizes or completes Incoming Feedback. This is done so that the Incoming Feedback will load as minimized immediately if they navigate to another page where it is set to show. 365 days _hjid Hotjar cookie. This cookie is set when the customer first lands on a page with the Hotjar script. It is used to persist the Hotjar User ID, unique to that site on the browser. This ensures that behavior in subsequent visits to the same site will be attributed to the same user ID. 365 days _hjRecordingLastActivity This should be found in sessionStorage (as opposed to cookies). This gets updated when a visitor recording starts and when data is sent through the WebSocket (the visitor performs an action that Hotjar records). Session hjTLDTest When the Hotjar script executes we try to determine the most generic cookie path we should use, instead of the page hostname. This is done so that cookies can be shared across subdomains (where applicable). To determine this, we try to store the _hjTLDTest cookie for different URL substring alternatives until it fails. After this check, the cookie is removed. Session _hjUserAttributesHash User Attributes sent through the Hotjar Identify API are cached for the duration of the session in order to know when an attribute has changed and needs to be updated. Session _hjCachedUserAttributes This cookie stores User Attributes which are sent through the Hotjar Identify API, whenever the user is not in the sample. These attributes will only be saved if the user interacts with a Hotjar Feedback tool. Session _hjLocalStorageTest This cookie is used to check if the Hotjar Tracking Script can use local storage. If it can, a value of 1 is set in this cookie. The data stored in_hjLocalStorageTest has no expiration time, but it is deleted immediately after creating it so the expected storage time is under 100ms.

Session _hjAbsoluteSessionInProgress The cookie is set so Hotjar can track the beginning of the user's journey for a total session count. It does not contain any identifiable information. 30 minutes
