Une étude réalisée au King’s College de Londres et publiée dans la revue spécialisée Ophtalmology, a révélé qu’une alimentation saine et riche en vitamine C permettrait de réduire d’environ 30 % le risque de développement d’une cataracte après l’âge de 60 ans.

En effet, après avoir analysé, à l’aide d’un questionnaire, les habitudes alimentaires de près de 1000 paires de jumelles, les chercheurs ont pu déterminer l’apport de leur alimentation en vitamine A, B et C ainsi qu’en cuivre, en zinc et en manganèse. Par la suite, ils ont mesuré, au moyen d’une IRM, l’opacité du cristallin ainsi que la progression de la cataracte.

À l’issue de l’étude, les chercheurs ont noté que le risque de cataracte était réduit de 33 % chez les femmes dont la consommation est plus riche en vitamine C. Pour cause, cette dernière est dotée de propriétés antioxydantes qui lui permettent de prévenir, sinon freiner ce trouble visuel. En détail, la quantité de fluide présent dans l’œil augmente avec une alimentation riche en vitamine C, protégeant ainsi le cristallin de l’oxydation.

  1. Can you be more specific about the content of your article? After reading it, I still have some doubts. Hope you can help me.

  2. What Is The Safest Anabolic Steroid?

    What Is the Safest Anabolic Steroid?

    Anabolic steroids are synthetic substances designed to mimic the effects of testosterone,
    a hormone produced by the body. They are often used for muscle-building purposes, either in medical
    contexts or among bodybuilders and athletes. Among the various types available,
    some are considered safer than others when used responsibly.

    Safest Anabolic Steroid?

    The « safest » anabolic steroid is subjective and depends on the context of use, intended purpose, and individual response.
    However, steroids like **Testosterone**, **Anavar (Oxandrolone)**, and **Primobolan** are often cited as having lower risk profiles compared to others.

    What Are the Common Types of Anabolic Steroids?

    Some common types include:

    – **Testosterone**: Naturally occurring hormone.
    – **Dianabol (Methandrostenolone)**: One of the oldest anabolic steroids, used extensively in bodybuilding.

    – **Nandrolone**: Known for its muscle-building effects and moderate side effect profile.

    – **Anavar (Oxandrolone)**: A milder steroid with fewer side effects.

    – **Trenbolone**: Often used for cutting or building due to its fat-burning properties.

    Intended Medical Uses Versus Bodybuilding Uses

    Anabolic steroids have both medical and non-medical uses.
    In medical settings, they are prescribed for conditions like muscle wasting, chronic illness, or hormonal deficiencies.
    However, in bodybuilding circles, their use is often for performance enhancement and aesthetic purposes.

    Comparison of Oral Versus Injectable Steroids

    – **Oral Steroids**: These are taken as pills or tablets and enter the bloodstream through digestion. Examples include Dianabol and Anavar.

    – **Injectable Steroids**: These are administered via intramuscular injection,
    allowing for controlled release into the bloodstream.
    Examples include Testosterone Enanthate and
    Cypionate.

    Injectables may be considered safer in terms of bioavailability, as
    they avoid gastrointestinal issues that can occur with oral steroids.
    However, injectables require more careful administration to prevent infections or
    other complications from improper handling.

    Steroids with the Least Amount of Side Effects

    – **Testosterone**: While it’s a natural hormone, excessive use can lead to androgenic side effects like
    acne, hair loss, and increased risk of prostate issues.

    – **Anavar (Oxandrolone)**: Often considered one of the milder steroids with fewer side effects, though it is still androgenic.

    – **Primobolan**: Another mild steroid with a good safety profile,
    especially in lower doses.

    Minimizing Risks When Using Anabolic Steroids

    To minimize risks:

    – Use the smallest effective dose for the shortest
    period needed (responsible « cycle » use).
    – Always follow a proper **Post-Cycle Therapy (PCT)** to restore hormonal balance after steroid use.

    – Monitor health closely during and after use, including regular check-ups and blood work.

    What Are the Side Effects of steroid abuse – ballotable.com -?

    Abuse of anabolic steroids can lead to a variety of side
    effects:

    – **Physical Side Effects**:
    – Acne
    – Hair loss (in women)
    – Deepening of voice in women
    – Enlarged male breast tissue
    – Liver damage
    – Kidney issues
    – High blood pressure

    – **Psychological and Health Risks**:
    – Mood swings or irritability
    – Paranoia or anxiety
    – Increased risk of heart disease
    – Hormonal imbalances leading to infertility (in both men and women)

    Physical Effects on Men and Women

    The physical effects of anabolic steroid use vary by gender:

    – **Men**:
    – Muscle growth
    – Increased strength
    – Possible testicular atrophy in extreme cases
    – Shrinkage of male breast tissue (gynecomastia)

    – **Women**:
    – Muscle growth (though less pronounced than in men)
    – Androgenic side effects like acne, hair loss, and facial hair
    – Potential for infertility due to hormonal imbalances

    Psychological and Health Risks

    Long-term use of anabolic steroids can lead to serious psychological health risks such as:

    – **Depression**
    – **Irritability**
    – **Aggression**
    – **Suicidal thoughts or behaviors**

    From a health perspective, steroid abuse can lead to chronic conditions like liver disease, heart disease, and diabetes.

    Regular monitoring is essential for anyone using these
    substances.

    How to Monitor Health and Minimize Risks During Steroid Use

    To stay safe while using anabolic steroids:

    – **Consult with a healthcare professional** before starting any steroid cycle.

    – **Regularly monitor your health** with check-ups and blood tests.

    – **Use the appropriate PCT** after finishing a cycle to prevent hormonal imbalances.

    – **Avoid combining steroids with other substances** like alcohol or drugs, as this can increase risk.

    In conclusion, while anabolic steroids can be effective for muscle building, their use carries significant risks.

    Prioritize safety by using them responsibly and seeking guidance from qualified medical professionals.

  3. This is usually done on your last set and in course of the
    tip of your exercise. If you want to hold your physique guessing
    and, in turn, keep your metabolic fee up, then you could alternate your days between ingesting a excessive and low amount of carbohydrates.
    Most athletes are most likely to have their high carb days during the extra intense training days
    (like leg day), alternating between these two phases helps maintain an accelerated metabolic price.
    While most of your nutrition might be coming from complete foods, you will
    need to take a multi-vitamin to find a way to fill in the gaps.
    The stress of bodybuilding on the physique can’t
    be overstated. If you aren’t ready with the best
    vitamins, then your body will succumb to overtraining. Be positive to buy a high
    quality multi-vitamin to take with breakfast.

    Taking a more prolonged rest lets you recuperate your power ranges
    and never be forced to cut back the load or the number of reps an excessive quantity of.

    Select weights that fatigue you throughout the rep range you’ve been given,
    and hold your rest times strict to maintain productiveness.
    If time and power allows it we’d advocate
    3-4 days per week within the health club to really increase your probabilities of growing power and gaining muscle.
    When it comes to beginning a strength and muscle building plan after 50,
    you won’t know the place to begin. In a 3-day split,
    the calves should be educated immediately solely
    as soon as per week. If one does operating or performs a sport,
    the calves are labored heavily in those actions. The shoulders and traps are trained
    immediately 1x per week however again, they’re synergists in Bench Press (Shoulders) and Deadlifts (Traps).

    Some say that coaching your abs is pointless, that other compound actions deal with them, and that abs are made in the kitchen. They develop larger and
    stronger, and if you’d like stand-out abdominals, deal with them like the remainder of your
    muscle tissue and work them onerous. Apart From, you don’t need that kind or amount of training but.
    You’ll expertise maximum features from a few units per muscle per week and get a gentle and efficient introduction to bodybuilding.
    Usually known as newbie gains, you quickly achieve muscle and
    become stronger whenever you take up weight training for
    the first time.
    The greatest full physique workout routine is three
    times per week since you’ll have simply three workouts per week with
    four days of relaxation between your workouts, which is
    good for a beginner routine. For the beginner lifter, this sort of
    training will help maximize muscle acquire until your fitness degree is ready for more superior exercises.

    Science has shown that a 3-day full body workout plan with complete relaxation days in between is
    good for constructing muscle and having sufficient and effective muscle recovery time.

    With Out it, you will by no means construct extra muscle than you’ve proper now.

    Don’t miss this opportunity to redefine your health and obtain new
    heights in muscle improvement and strength. E-book your free consultation and take step one towards a stronger, extra
    confident you. Because of this, the upper/lower split scores quite well, with a hypertrophy score of 8.four, simply enough to earn the highest
    spot. Nicely, while the latest knowledge suggests frequency doesn’t appear to be as
    important for development, it nonetheless helps provide a small enhance.

    And while it takes the top spot on the leaderboard for now, the subsequent workout
    split will give it a run for its cash.
    There is little to no evidence that these supplements will aid your bodybuilding efforts.
    Examples of probably helpful bodybuilding dietary supplements embody vitamin D, omega-3 fatty acids, multivitamins, and important
    amino acids. Instead, management your energy
    along with your food plan and progressively introduce cardio.

    Different supplements like fat burners, BCAAs, and others claiming to « boost » your hormones, are usually a waste of cash
    during a bodybuilding cut. Dietary Supplements should not be relied upon as a substitute for a balanced
    food regimen throughout a bodybuilding cut, but they are often helpful when you’re making an attempt to get
    shredded. If you’re already an experienced bodybuilder, you
    have a headstart over all your same-age friends.
    However when you’re consuming in a caloric surplus to gain muscle, don’t
    be afraid to treat yourself now and then.
    Too many guys flit from one program, training system or
    nutritional plan to another without giving their physique the time to learn from what they’re doing.

    Whether Or Not trying to step on stage, get in form,
    or be taught a factor or two about bodybuilding, many contemplate this book to be vital.
    Arguably the most well-liked function of The New Encyclopedia of
    Trendy Bodybuilding is the coaching packages, together with primary and advanced variations.

    AFTER AGE 50, avoiding harm replaces progression as your number-one priority.
    If something hurts, stop immediately and try a different exercise for a similar muscle group, or transfer onto one thing else.
    That said, you can run this while you’re slicing as properly.
    If you choose to do that, your deficit might be affected by your body fats percentage.

    Make positive you’ve at least 6 months worth of stable
    coaching experience earlier than you attempt a excessive frequency break up like this.
    It’s all about thick, vascular muscle mass and bar-bending, brute-force energy.

    This sort of workout will permit your body to recover and you might
    find that you’re stronger when you start back on your regular routine.

    Say goodbye to mediocre results and howdy to a physique that commands attention. After six reps, pause in the backside squat place for 3 seconds.
    Now do one other 6 partial reps, pause for three
    seconds in the bottom squat and then end with a last six partial reps.

    That’s since you’ll be making use of a little recognized technique known as Satan Sets.

    But sustaining this excessive heart price also
    helps enhance your metabolism (the amount of energy you
    burn all through the day). It can take time for positive, however
    what we’re after is so that you just can obtain regular and frequent workouts in the early phases of your program.
    Constructing mounds of strong, lean mass doesn’t occur overnight.

    And that’s why we’ve given you a time frame of 3-months
    to make some actual differences to the muscle that’ll persist with your
    frame like a badge of honor. In this detailed guide we take you through every step of
    the mass constructing process. This is your primary place
    to actually push the boundaries and etch out a physique like
    you’ve never achieved before.
    This will prepare the joints, the muscular tissues and
    the nervous system that controls those muscles for the heavy work
    to come back. Like the squat, the leg press targets
    the thighs and hips, however with much less involvement from
    the core muscles, the spinal erectors particularly.
    If you’re coaching at house with no leg press
    machine, go with one of these leg press alternate options.

    Whereas the squat is a superb lower physique train, it doesn’t hit the hamstrings very hard,
    which is the place the leg curl comes in.
    Though the seated leg curl has been shown to work better than the lying leg curl for constructing
    hamstring measurement, each are nonetheless very effective,
    so just use no matter machine is available. Next up is the
    reverse grip lat pulldown, which targets your back and biceps.

    The secret is you don’t want to train greater than 2 days in a row with
    most of these workouts. But you also don’t want to
    go greater than 2 rows of rest between workouts. This is so that you’ve enough
    energy and vitality firstly for the 5 x 5
    lifts. If you did all legs then began with shoulders, you wouldn’t be as robust
    on that first 5 x 5 shoulder exercise. This additionally adds
    a little wanted spice to your workouts by changing it up from the
    norm. James is Tom’s Information’s Shopping For Guide Editor, overseeing the location’s
    shopping for advice. Fixed-load weights will do, but should you frequently train at residence, it’s worth
    investing in a set of the greatest adjustable dumbbells.

    These mix several weights, making them simpler to store, and you may improve
    the load as you get stronger. We’ve factored in every thing from exercise selection and
    order, to load and rep ranges in addition to volume. In this 6-8
    week mass building exercise we’ve used our collective information of coaching, coaching and research to devise the
    perfect beginner schedule. When you prepare
    with weights you create microscopic tears in your muscle fibers.
    This occurs a results of the strain that passes by way of every muscle when load or volume is added.

    Take lean body weight in kilos and multiply by 1.0 to calculate daily protein consumption in grams.

    This quantity ought to stay fixed on training and
    non-training days. So our man with 180 kilos of lean physique mass should consume 200g of protein daily.
    Multiply this quantity by 4 to calculate what number of energy you will derive from protein, so the 180-pound
    male would get 800 cal. Your first four weeks are going to be all about
    constructing a strong foundation of mass and
    power. Whether you’re new to bodybuilding or you’ve been in this recreation for some time,
    these workouts will simply assist you to pack on some critical dimension. Because you’ve trained your chest,
    back, and shoulders heavy, you possibly can actually
    concentrate on building and shaping your biceps and triceps with
    isolation movements.
    Avoid using momentum or swinging the burden up using your hips, as that can take away
    work from the intended working muscles. That means it’s
    worked to some extent in rowing exercises just like the bent-over row, however you probably can target it even further with workouts just like the reverse
    dumbbell fly, pictured above. The overhead press is as old because the barbell itself,
    and is possibly the best shoulder train of all.
    I recommend preserving your relaxation intervals between two and three minutes.

    It is a fable that you need multiple train per « physique part » to build
    a nicely balanced muscular, athletic physique in case you are training heavy
    with sufficient depth. To be clear, coaching for 4 or 5 days per week is still extraordinarily effective because it allows you to get
    in additional work quantity. Nonetheless, fatigue management becomes a bit more necessary as it’s simpler to burn out, particularly for novices.
    I love full body workouts as a result of
    each train counts, leading to a coaching program the place every single exercise is of
    utmost importance. If you plan on coaching greater than three days a week, choose a different
    exercise break up. There are loads of wonderful
    4-day,  5-day, 6 day (and even 7 day) splits; they’re simply not full body.

    Jump out of bed the following day with pleasure, figuring out
    that you are going to smash your exercise. As you head out the door,
    your mental depth level must be at about 7 out of 10.
    Driving to the fitness center, see your self efficiently finishing your max lifts again, and dial it up to a
    9.
    Protein is the building block of your body, and should you
    don’t eat sufficient of it, you’ll have trouble constructing muscle.
    All the upper-body exercises I talked about above work your biceps and your triceps very successfully.

    For instance, studies show that lat pulldowns make your biceps
    grow simply as a lot as devoted biceps curls. All workouts should use a
    weight that tires you inside 8-12 reps. Complete 3
    sets of every train and aim to rest round 2-3 minutes
    between workout routines. As science has progressed we’ve realized that unless you’re
    hitting the health club most days of the week,
    whole-body coaching is the greatest choice. In this information, we
    tell you everything you should know about coaching for the older man.
    The actions that work your again and biceps are all pulling actions.
    This is the best setup in terms of building  mass because you
    are ready to break down and focus on complimenting muscle teams all in one exercise.
    Even a modest amount of muscle gain mixed with low physique fat levels makes a
    huge visual impression. For instance, whereas 3-day splits may be very effective, they typically go away you time
    to coach a muscle group or motion with 3-4 workouts a
    week. This just isn’t necessarily bad, however it means you have less of
    an opportunity to be particular about your exercise choice.
    A superset means performing two workouts back-to-back with out relaxation in between. The workouts can target the
    identical muscle group or totally different
    muscle groups.
    But as is the case with variation, nothing is the most
    effective for eternally. So, uh, sooner or later, you know,
    should you really love seated leg curls, you are gonna strive mendacity leg curls
    and they’re gonna blow you outta the water simply since you’re
    not used to them. Excessive bar barbell squats, Smith
    machine squats, leg presses, hack squats, belt squats, and correctly carried out leg extensions — I would say that basically kind of rounds out quad training.
    I would say doing your calf raises with a straight leg
    stretches the gastroc venous muscle and thus also makes it grow a lot, much more impressively than doing them with a bent leg.
    If you’re thinking about learning tips on how to construct muscle,
    you should learn this article.
    Take 15 grams of citrulline an hour earlier than showtime to widen your blood
    vessel and improve blood move to your muscles. Research show that this doesn’t work, but 1) they
    use low doses, and 2) your physique reacts rather more powerfully when you’re this conditioned.

    Identical protocol as yesterday, however
    cut back your carbs to five grams per kilogram of body weight.
    You’re past the purpose where you presumably can retailer essentially the
    most vital quantity of carbs per hour, and you don’t need them
    to spill over.
    Next to protein, creatine is doubtless one of the tried and true bodybuilding supplements.
    Creatine converts into ATP inside the body, permitting you to push yourself more durable during
    every exercise. It additionally plays a optimistic position within the post-workout restoration process.
    A high quality creatine complement will give you 5 grams per serving.
    Our flagship pre-workout supplement ALTIUS contains a full 3
    grams of creatine, in addition to our post-workout complement POWERBUILD.

    If you’re bored with utilizing other splits or not seeing results, we’re pretty positive this can get you
    the results you’re seeking. This intermediate exercise
    plan is a four day break up workout routine.

    That is, you exercise 2 days followed by rest and understanding one other 2 days and another 2 days of
    rest. You should give your muscular tissues enough time to recuperate from each workout days and stimulate correct muscle development.

    Full-body exercises may be made to work for beginner, intermediate and superior trainees alike.

    Following your top set, you’ll scale back the load by
    about 10 to fifteen p.c and do two extra units of eight to 12 reps.
    Our final train on this mega muscle building workout is the one arm dumbbell row.
    Of all the versions of the row, this one does the best job of hitting your latissimus dorsi and your rear delts.
    To get the best bang in your buck from this train,
    do not pull the dumbbell straight up as if you’re beginning a lawnmower.

    Somewhat, pull it across your physique and up whereas resting your non-working hand
    on an incline bench in entrance of you. Do Not do the exercise with one knee on a bench as it will limit your
    capability to get that cross pulling motion that actually
    brings the lats into play. Whereas it’s true that your
    muscles need variation of their coaching, you also want to give them
    continuity.
