Proteínové mliečne výrobky a množstvo cukru v nich

Napísal Miroslava Boškovičová 02. február 2024

V posledných rokoch sa popri obvyklých jogurtoch alebo pudingoch objavujú podobné výrobky sľubujúce vysoký obsah proteínu, čiže bielkovín. Spotrebiteľská organizácia dTest poslala do laboratória 16 takýchto výrobkov z kategórie jogurtov, dezertov a skyrov, z ktorých väčšinu je možné kúpiť aj na Slovensku.

Každá z kategórií vyniká niečím iným a tak si každý môže vybrať, čo mu bude najviac vyhovovať. Správna voľba však nemusí byť jednoduchá. Nie všetky výrobky totiž obsahujú to, čo sľubujú.

Základom mliečnych proteínových výrobkov je obyčajný jogurt, puding alebo tvarohový dezert, do ktorého je pridaná bielkovina naviac. Výrobcovia najčastejšie používajú bežné mliečne bielkoviny, ktoré sú základom tvarohu a syrov, pri niektorých testovaných produktoch sa laboratórium stretlo aj so srvátkovými. „Do nášho výberu sme zaradili aj skyr. Tento špeciálny kvasený mliečny výrobok z Islandu sa výrobou aj vlastnosťami pohybuje na hranici medzi tvarohom a jogurtom, preto je na bielkoviny bohatý prirodzene,“ vysvetľuje šéfredaktorka časopisu dTest Hana Hoffmannová.

Kľúčom pre výber 16 testovaných vzoriek bol jasný odkaz na bielkoviny v názve. Do laboratória sa tak dostalo sedem vanilkových a ovocných dezertov, štyri prevažne jahodové jogurty a pätica skyrov. „Iba skyry sme nakupovali podľa ich mena, nie podľa zmienky o bielkovine,“ upresňuje Hana Hoffmannová voľbu výrobkov.

Množstvo bielkovín bolo logicky tým prvým, čo sa v laboratóriu zisťovalo. Mliečna vyhláška kategóriu proteínových výrobkov nepozná, takže na ne nekladie žiadne špeciálne požiadavky. Vzorky sa tak predovšetkým porovnávali medzi sebou: „Najvyššiu porciu bielkovín ponúkli dezerty, v priemere 9,7 g/100 g výrobku, druhé miesto potom patrilo jogurtom s 8,6 g/100 g a posledné miesto obsadili skyry – v priemere s 7,6 g/100 g,“ vymenováva šéfredaktorka Hoffmannová. Vôbec najväčšiu nálož bielkovín v balení ponúkol dezert Lidl/Pilos High Protein Quark Strawberry, a to 23,7 g. Naopak, najmenej bielkovín nameralo laboratórium vo výrobku z Bohušovickej mliekarne Skyr islandská tradícia jahoda – celkovo 9,6 gramov v 130 gramovom balení.

Spomínaný bohušovický skyr sa spolu s výrobkami Lidl/Pilos Skyr Jahoda a Bohušovická mliekareň Protein Jahoda nezmestili ani do tolerovanej 20 % odchýlky údajov uvedených na obale. Všetky tieto výrobky tak získali nedostatočnú známku, pretože pri nich prišlo ku klamaniu spotrebiteľa.

Nepríjemné prekvapenie čakalo aj pri nameraných hodnotách obsahu cukru. „Ukázalo sa, že niektoré výrobky obsahujú viac cukru ako bielkovín. Dezert Bohušovickej mliekarne Protein Jahoda obsahoval v celom balení len 10,8 g bielkovín, ale 19,3 gramov cukru,“ upozorňuje Hana Hoffmannová z dTestu a pokračuje: „Menší podiel cukru bol potom pri niekoľkých testovaných výrobkoch kompenzovaný umelými sladidlami. Podľa nás je však lepšou cestou k zníženiu príjmu cukru privykanie na menej sladkú chuť, náhradné sladidlá za ideálny prostriedok nepovažujeme. Dobrý dojem na nás urobili výrobky Lidl/Pilos Skyr Jahoda a Bohušovická mliekareň Protein Vanilka. Pri týchto sa aj bez pomoci náhradných sladidiel podarilo nastaviť receptúru tak, aby obsahovali viac bielkovín ako cukru.“

Po senzorickom hodnotení, ktoré vo všeobecnosti dopadlo dobre, sa laboratórium zameralo ešte samostatne na jogurty a skyry. „Keďže ide o fermentované mliečne výrobky, nechali sme špecialistov spočítať, koľko ukrývajú mikroorganizmov. Podľa vyhlášky má byť v grame jogurtu aspoň desať miliónov baktérií streptokokov a laktobacilov. Pri výrobku Zott Protein Yogurt Product Strawberry sa našli len desiatky tisíc. K porušeniu vyhlášky však nedošlo, pretože podľa oficiálneho názvu nejde o jogurt, ale o jogurtový výrobok. A pre ten vyhláška neplatí. Opäť sa tak potvrdilo, že je potrebné čítať obaly a etikety veľmi dôkladne,“ uzatvára Hana Hoffmannová za dTest.

Kompletné výsledky testu mliečnych proteínových výrobkov vrátane všetkých kategórií nájdete na webe dTest.

    Simply as you would not wear denims to an indoor cycling class,
    lacing up running shoes to weightlift is not going to result in optimal efficiency.

    Sneakers are designed to swimsuit your athletic wants, especially
    if you are carrying a load. Asics used to take custom orders on these shoes,
    but that service appears to have been discontinued.
    With a really high heel and powerful foot help, the Adipower IIIs
    are additionally a variety of the finest sneakers for weightlifting for
    lifters who're tall or have very long femurs. They
    are also an excellent shoe for lifters who are advanced of their sport and lift heavy weights.
    The Adidas Powerlift 5s additionally price much less than different premium weightlifting
    footwear, making them a variety of the best shoes for lifting for people on a finances.
    In this article, I will undergo what to contemplate when buying weightlifting footwear, the most effective weightlifting shoe for numerous scenarios, and
    every little thing you should know to assist you determine which ones to purchase.
    These are the best weightlifting shoes general, but that doesn't essentially mean that they're universally appropriate for everybody.
    The toe field on these sneakers is wider than most, which is right for deadlifts.

    I additionally feel as though this model will align really well with ladies athletes’ foot anatomies.
    Third and lastly, I just like the Graphene-infused Powerheel, midfoot security,
    and light-weight nature of this shoe. This model locks down the toes nicely and
    the heel feels light-weight and steady for catching weight.

    If you have extensive ft or want extra toe box room, then I’d counsel passing on the Legacy Lifter II and going with the TYR L-1 Lifter as a substitute.
    Cross-training shoes have particular development particulars
    that make them appropriate for versatile coaching. They’re sneakers designed to tackle things
    like lifting, plyometrics, and lighter runs all in one workout.
    If it feels unimaginable for you, then certainly this weightlifting shoe you got
    isn’t really for you.
    In truth, they are often significantly beneficial for those just starting out
    with weightlifting and nonetheless working on their type and method.

    The dual strap system provides a stable hug on the
    foot for max stability, too. This shoe has slightly more aggressive
    arch help than another weightlifting shoes on this list, so it
    works properly for many who need slightly additional lift under the midsole.
    One Other more modern examine similarly found that compared to extra basic athletic footwear,
    weightlifting footwear reduced ankle motion and helped lifters
    maintain an upright torso throughout squats. Some weightlifting shoes have raised heels,
    which are better for squats and Olympic lifting, whereas
    different footwear are flat and work better for most other
    forms of weightlifting. Some weightlifting shoes have a raised
    heel as a result of it helps along with your ankles' range of
    motion when stepping into sure positions similar
    to squats, overhead squats and snatches.
    We love a great, foam-laden sneaker (and your shoe can have some cushioning if you plan to make use of it for cross-training), however a
    more durable sole is the higher alternative for when you’re lifting.

    Rogue Health is well-known for producing prime quality gym equipment, however you might not know that the brand also makes a strong weightlifting
    shoe. The shoe offers a wide, flat heel to give you stability whereas shifting between exercises, in addition to durable rubber treads for ample traction.
    Regardless Of the broad base, the toe field is pretty narrow, so most patrons
    recommend going up a half measurement if you're not a fan of a
    comfortable fit or have broad feet. Adidas's Powerlift 5 is a viable option for
    these not seeking to break the financial institution on a
    strong shoe to squat and do other Olympic lifts in. With a heel elevation of just sixteen mm, they're especially
    nice for newbies, these new to lifting in an elevated heel, or
    those who simply favor a lower heel elevation. A wider toe box
    permits you to spread your toes, which offers better
    stability. At the identical time, the narrower field is intended to
    allow the transfer of more energy.
    If you’re just beginning your power journey or not planning to raise ultra-heavy, I advocate the Adidas
    Powerlift 5 weightlifting sneakers. Nevertheless, critical lifters with
    an even bigger finances will benefit from upgrading to a higher-end mannequin with better specs.
    The Legacy Lifter III are high-quality weightlifting footwear with a
    true-to-size match and an ultra-stable 22mm heel.

    They're very well-rounded and best for powerlifters and Olympic
    weightlifters.
    The profit being you can grip the ground more successfully and exercise your
    foot's dexterity whereas understanding. It would not harm that it's a fashionable shoe so
    it might be worn exterior of the health club as properly.

    I tested these shoes with squats, deadlifts and then a HIIT exercise that included drugs ball throws and slams, squat jumps and leaping
    jacks.
    ? These athletes, in my opinion, vastly
    overestimate the quality of their positions,
    however extra considerably, this argument ignores the pressure transfer and stability high quality.

    Mobility may and ought to be enhanced or maintained in ways apart from simply squatting.
    For everybody proper within the center, critical about coaching,
    and in it for the lengthy haul with no illusions of constructing
    an Olympic team, these could be a great choice. Not too expensive, very sturdy,
    lighter, sleeker, and extra athletic- heck, they’re
    even lighter without insoles than the present
    Metcon eight. If you have further construction-related questions
    on the Nike Romaleos three, drop a comment beneath
    and I may help you out. If you may have extra sizing
    and fit questions in regards to the Nike Romaleos
    3, drop a remark below and I may help you out accordingly.
    Despite enjoying the Nike Romaleos three over the past 4 years of
    my utilizing them, I have discovered a quantity of cons to be weary and know
    before investing in this shoe.
    Strengthening the muscles in your ft can even help to protect from injuries up the chain. Love the
    look of old-fashioned lifting shoes but want the improvements in consolation of newer renditions?
    With a stacked leather heel for ultimate comfort and shock absorption, this newly reimagined mannequin strikes a steadiness of athletic and old fashioned.


    It’s also a wise choice for a ‘squat shoe’ – perfect for powerlifters
    and CrossFitters.. I want to mention one simple fix for
    the "okay, what quantity of sneakers do I have to deliver to the gym??" drawback.
    You won’t have any cushioning beneath your feet, and you will not have that 3/4" heel either. I talked about above that I wear lifters for my Olympic weightlifting workouts.
    If you are in search of a serious shoe to deadlift in or wear for long runs, this gained't be your only option, but the Puma Fuse 2.zero is suitable for nearly every little thing in between. The Altra Solstice XT2 is our pick for best various cross-training shoe. The Vivobarefoot Primus Lite III is an effective choice for these who take pleasure in training barefoot. The Nike Romaleos and Adidas Adipower are premium choices with a modern TPU heel and aesthetics, while the Inov-8 Bare is a minimalist shoe many CrossFitters may love. We’ve coated the heel material, however the relaxation of the shoe supplies are also necessary.
    The Versalift heel inserts are an inexpensive and effective answer for ankle mobility. I would argue that enhancing ankle mobility by way of deliberate coaching is healthier, but Veraslifts are the second-best thing. The shoe’s backside is similar to the Romaleo 2 design but with extra trendy, "sharper" edges for a sleeker look. The elevated stability can be felt because the shoe’s sole is slightly longer and wider in some places than the shoe itself. While plastic heels are extra durable, the traditional wooden heel will never go out of favor. Moreover, wood has been demonstrated to soak up some of the vitality and shock from weightlifting, making it somewhat gentler on the joints. With its exceptional quality and iconic wood heel, they outperform all other prime brands and fashions.
    The Reebok Legacy Lifter III is fascinating as a outcome of it’s a strong-performing shoe, nevertheless it does have a couple of cons that I think are value acknowledging. Another thing to love concerning the Reebok Legacy Lifter III is that I assume there are contexts the place the pump system might be helpful. The pump system runs via the tongue of this shoe and inflates to enlarge the amount of the tongue. Over the course of my evaluate course of and testing with the Reebok Legacy Lifter III, I discovered a few things to essentially enjoy about this shoe. Lastly, I assume if you love Reebok and the novelty of the pump system, then I could see you also really enjoying the Legacy Lifter III. The pump isn’t essentially a make or break with this regarding its performance, but it does add a cool factor to this mannequin.
    Maybe you’ve taken a liking to powerlifting and need a kick for getting the most out of these massive three lifts. Maybe you’re simply wanting some added stability for squat days and wish to really hone in on conquering those training plateaus. Whereas the record of weightlifting sneakers may be troublesome to digest for newcomers, there’s no want to worry — we can present a spot.
    The Reebok Lifter PR II is a much cheaper various to the Reebok Legacy Lifter II. It has a breathable textile higher to let sweat evaporate and an EVA foam midsole for light-weight cushioning. The higher makes up the majority of the shoe, so material choice is important for consolation, sturdiness, breathability, and appears. You’ll generally find materials (ripstop, mesh, knit, etc.) and leather-based (natural and synthetic). High-quality sneakers will embrace strengthened seams, tight stitching, and constant gluing. Some sneakers additionally supply wooden or stacked leather, however these are less frequent and usually don’t last as long. The GORUCK Ballistic Trainers are a few of the most comfy, sturdy, and trendy trainers I’ve used.
    This Vivobarefoot Motus Power shoe is understood for its basic zero-drop design that Judd loves for weightlifting. Whereas this fashion is flat with minimal cushion to maintain heels even with toes, Judd notes that this explicit shoe provides "added protection and durability" from its sturdy rubber sole and higher. They're marketed as a more versatile weightlifting shoe, which we don't usually advocate. Selecting the best weightlifting footwear entails a couple of elements, corresponding to heel top, heel materials, toe box width, and private construct and preferences. They have a large structure and toe field, which is good for folks with extensive ft. There are three main differences between weightlifting and cross-training sneakers, including heel top, heel hardness, and shoe weight. Weightlifting shoes are inclined to have a better heel height and a harder material for the heel to tolerate larger absolute loads such as when heavy squatting.
    For someone who doesn’t have or know their height preferences, the Do-Win Weightlifting Footwear could be a perfect middle floor. Whereas it is a balanced top for most, those who prefer a taller elevation may want more. Finally, these are excellent footwear, however you could find them uncomfortable in case you have wide ft. April Benshosan is a Verywell Match author and experienced weight lifter (in reality, her favorite pastime is hitting PRs). April relies on Nike Metcon 9s and Metcon 6s to get her by way of leg days and short cardio sessions after upper physique workouts. April has been overlaying fitness and well being products for nearly a decade, since the begin of her journalism profession.
    The toe cap on the entrance of the shoe is created from a single strip of leather-based and reinforces the toe box. Since the fabric is double thickness on this space, it makes the shoe really feel tighter at first. However similar to a great pair of actual leather-based costume sneakers, these stretch over time and truly produce a wider than average toe box. Cross-training shoes can be utilized in a selection of totally different coaching settings. I all the time suggest lifters and athletes just have a pair of cross-training shoes on deck for general coaching functions. Plus, if you take care of your cross-training shoes they’ll often last some time and be a stable funding. Also, for you, as a trainer, have them use a heel wedge to understand what it’s wish to have these knees tracked ahead while balancing various masses.
    And, unlike extra rigidly structured footwear, the Fastlift Power G 380s permit for free movement. You’ll also be ready to experience the feeling of understanding barefoot with the security of a puncture-resistance base (plus a lightweight zero.8mm rubberized layer on the sole) for added protection. The shoe also features a strap across the highest to offer a locked-down feeling and help forestall unwanted ankle and foot movement.
    This extra instability just isn't dangerous (that's a myth) however when you raise in running shoes, you are missing an opportunity to provide your self a properly stable base. For example, this model takes virtually no time to break during which is pretty uncommon for weightlifting sneakers. In the forefoot of this shoe you, you have a Graphene rubber outsole and insole that separates the foot from the ground and that’s virtually it. The Adidas Powerlift 5 has a less expensive price ticket than lots of the other big-brand shoes, however it’s splendidly succesful under load.
