Šálka čaju...(II.)

Napísal femme 20. február 2019

Viaceré vedecké tímy sa už dlhší čas snažia dokázať, že čaj prospieva ľudskému organizmu. Čierne a zelené čaje majú podľa vedcov preventívne zdravotné účinky.

Podľa čínskych análov ľudia začali piť čaj okolo roku 2000 pred. n.l.; a keďže prvé písomné záznamy o čaji pochádzajú z lekárskej knihy (1. až 2. storočie n.l.), dá sa predpokladať, že čaj bol spočiatku považovaný za liek. Až v 14. storočí sa stal z čaju všeobecne rozšírený, obľúbený nápoj.

Zelené lístky čaju sa získavajú z kríka pomerne malého vzrastu, ktorého domovinou sú subtropické a tropické oblasti - niekedy značnej nadmorskej výšky (jeden z vynikajúcich čajov pochádza napríklad z chladných oblastí indických Himalájí). 
Čajové lístky sa zberajú 4-5 rokov po výsadbe čajových kríkov, a to niekoľkokrát za rok. Pozbierané čajové lístky sa najskôr nechajú zvädnúť a následne sa spracujú tak, aby z nich vytiekla šťava; potom dochádza k procesu fermentácie, výsledkom ktorého je čierna farba čaju a jeho charakteristická chuť a vôňa. Pri príprave zeleného čaju sa čajové lístky najskôr sparia, čím sa zničia enzýmy a zabráni sa tak fermentácii. V prípade, že proces fermentácie čajových lístkov nastane a je predčasne zastavený, vzniká tretí druh čaju (čiastočne fermentovaný), ktorý nesie názov oolong.

Pozitívne účinky čaju:

- Dlhodobé štúdie čierneho čaju potvrdili jeho antioxidačné možnosti a vplyv na zníženie zrážanlivosti krvi. Celkom jednoznačne sa preukázali priaznivé účinky čierneho čaju na mozog a cievy. Austrálski vedci tiež zistili, že čierny čaj zvyšuje obranyschopnosť pokožky, na ktorú útočia slnečné lúče. 

- Pitie zeleného čaju chráni pred oxidantami obsiahnutými v cigaretovom dyme, pred poškodením kože vplyvom UV-lúčov, ako aj pred ochorením na rakovinu žalúdka a pažeráka. (Platí, čím viac skonzumovaných šálok čaju, tým lepšie.)

- Pri oolong čaji sa zistilo, že má schopnosť pôsobiť zhubne na nebezpečné baktérie ústnej dutiny podnecujúce vznik zubného kazu (tlmí schopnosť baktérií priľnúť k zubnému povrchu, čím bráni produkcii kyseliny, ktorá poškodzuje zubnú sklovinu).

    Related to testosterone restoration, we must additionally look to drive down estrogen levels on the conclusion of our prohormone cycle.
    I am now on my post-cycle remedy and I even have already seen some benefits
    of Tamoxifen First, my vitality levels have increased
    and I am sleeping higher at evening. I have also noticed that my muscles are
    beginning to feel stronger and my restoration time after
    exercises has decreased. The antagonistic impact of
    Nolvadex impact I have skilled so far is delicate nausea, but that has only been an issue on days once I
    take it on an empty abdomen. There’s a vast variety of medication available that bodybuilders have discovered to be useful at sustaining
    and restoring hormone ranges after steroid use.

    PCT entails taking medication that stimulate your pure
    testosterone manufacturing or block the results of estrogen.
    These medication are usually taken for a number of weeks after a cycle, relying on the kind and
    period of the steroids used. High ranges of estrogen can result in points, similar to gynecomastia and water retention.
    If your plan is to solely take a month off earlier than your subsequent cycle, don’t PCT.

    Until you're taking a minimum of the same length as your cycle off (preferably longer), then don’t PCT.
    Before you do a PCT (and earlier than you even cycle) you should be operating
    blood checks. These all play very important roles
    in your well being, and to see how and when to cycle next, you should
    know these three things. Yup, you could find yourself
    with undesirable muscle mommy issues when you don’t manage your hormonal levels.

    Clomid is taken into account very robust, while Nolvadex
    is weaker, so some individuals think about using both.
    However this does not take away the chance of unwanted effects;
    it’s likely to improve them. SERMs, however, goal specific
    estrogen receptors and are used to deal with critical conditions like breast most cancers, as well as menopause, osteoporosis,
    and infertility. Bodybuilders use SERMs in post-cycle
    therapy to fight the looks of gyno that comes about from elevated
    levels of estrogen following a cycle of steroids. [newline]A PCT cycle can final
    anyplace from three to six weeks, relying on the steroid
    cycle you had been on and the PCT medicine you will be utilizing.

    My best post-cycle therapy protocol above lasts between 4 and six weeks for
    the standard person.
    This is all thanks to its capability to promote collagen synthesis for strengthening joints
    and connective tissue. Most Deca-Durabolin users will notice this impact greater than with other
    steroids, together with a notable reduction in joint
    pain and basic aches and pains. Whereas bodybuilders and athletes have used Deca-Durabolin for nicely over 50 years,
    no anabolic steroid can ever be proclaimed as secure when used for
    performance enhancement purposes. The Nandrolone hormone comes with fairly highly effective testosterone suppression activity,
    and this will be the best concern for many (male) customers.

    Different steroids usually stacked with Deca are Equipoise,
    Anadrol, and Masteron, depending in your objectives.
    Both pharmaceutical and underground lab merchandise can be found for Deca-Durabolin and,
    extra rarely, NPP. If you’re in the US, where there are
    heavy restrictions on anabolic steroids and where Nandrolone is now not manufactured within the nation, then the one pharmaceutical
    Nandrolone you can buy are imported merchandise. This will nearly solely be Deca-Durabolin, with NPP being tougher to
    find in the US in pharma grade.
    It additionally means constantly being vigilant about possessing and
    using Trenbolone as a outcome of the penalties can be extreme.

    In the US alone, potential massive fines and jail time are a real possibility
    for anyone getting caught with Trenbolone or other steroids.

    Positive Trenbolone reviews concentrate on how a lot muscle has been gained and how quickly (expect it to be quite fast), energy features, and fats loss or physique recomposition. Nonetheless,
    if Trenbolone Enanthate is all you possibly can access, there’s actually no slouch in the chopping division, notably
    as we don’t have to fret about water retention. We can by no means say that any steroid is secure for bodybuilding or
    efficiency. While a quantity of other steroids have medical approval for use
    in humans at low doses, Trenbolone isn’t certainly
    one of them.
    So, you get to maintain your positive aspects, with the
    added bonus of having clean and healthy skin. If you bear in mind
    what happened when you went via puberty, the sudden enhance in testosterone brought on you to develop
    spots and pimples. When men use steroids, they do so because they want to look higher
    and feel better about themselves. Gynecomastia is caused
    when androgens in the physique aromatize because of aromatase
    enzymes, causing a man to undergo from female characteristics.
    It is rumored that The Rock himself had gynecomastia surgical procedure throughout his WWF days in the late 90s.

    As it's an AI, it really works by disabling aromatase enzymes which trigger androgens
    corresponding to testosterone, to aromatize and convert to Estrogen.
    However, as soon as a cycle ends, the body’s pure testosterone manufacturing
    is suppressed, leading to potential side effects like muscle loss, fatigue, and hormonal imbalance.
    A well-structured PCT helps restore pure testosterone levels, minimizing the dangers of estrogen dominance and sustaining muscle positive aspects.
    Tamoxifen (Nolvadex), a selective estrogen receptor modulator
    (SERM), plays a crucial role in post-cycle remedy (PCT) within the bodybuilding community, notably in the prevention of estrogen-related side effects.
    When anabolic steroid cycles are discontinued,
    the body’s natural manufacturing of testosterone is suppressed,
    leading to an imbalance within the estrogen-to-testosterone ratio.

    The conclusion right here is that using Arimidex or Letrozole with Nolvadex
    collectively is a very unhealthy concept and may work counterproductively if used together in a
    PCT protocol. In one research, Aromasin displayed no such reduced
    effectiveness or any lowered blood plasma ranges when utilized with Nolvadex[6].
    This detection and adjustment, generally recognized as the adverse suggestions loop, is controlled
    by the hypothalamus, which is actually considered the ‘master’ gland for all endocrine and hormonal capabilities
    within the physique. All endocrine glands operate
    by means of the negative suggestions loop in a method or one other, and to various degrees.

    Most of the side effects that come about when utilizing Testosterone
    Enanthate will be short-term. As Soon As you stop using the steroid and permit a quantity of weeks for it to clear your system, virtually all unwanted aspect effects will
    subside. Testosterone Enanthate must be utilized in planned cycles with suitable time between cycles to permit
    restoration.
    This may cause a huge hormonal imbalance in your physique and that hormonal balance is going to
    continue until testosterone manufacturing is ramped up once more.
    Another important operate of using HCG is that it additionally cures testes shrinkage – testicular atrophy.
    The use of steroids can result in low or even non-existent levels of natural testosterone that cause testicular atrophy.
