It depends on what you mean by "sports nutrition". If it is protein, casein, various dietary supplements (for example BCAA), then with proper use they will only benefit. To do this, you need to observe the dosage and choose proven brands that will definitely not sell fake.
If steroids, anabolic steroids and other chemicals that artificially accelerate muscle gain are called "sports nutrition", then yes, it is harmful .
In any case, do not forget that sports nutrition is always an ADDITION to the main diet. You cannot make protein shakes the only source of protein for your body. For sports nutrition to work, it must be combined with ordinary foods that contain proteins, fats, carbohydrates, amino acids and other useful elements.
Also, do not forget about physical activity. Even the best and most expensive proteins and gainers will not help you build muscle without well-designed, regular workouts.
I think this is a stupid stereotype. How many years I have been studying and drinking, I am interested in this topic, then I do not see any harm in this. Of course, you do not need to indiscriminately buy everything, but what the coach will advise you, or specifically what you understand you need for the result. I advise you to take it in trusted sports nutrition stores and do not go too cheap and you can start with American manufacturers. Their quality is the best
It depends on what exactly to consider. If you mean protein-carbohydrate mixtures, they have the same effect as regular food: a large amount of protein loads the kidneys, sugar raises insulin, etc. If special supplements are like fat burners, then the side effects will depend on the composition. Caffeine, yohimbine raise blood pressure and heart rate, vitamins - are reflected in the liver. In general, the same as ordinary food or medicines and supplements bought at the pharmacy.
In any case, ordinary doctors will be against it. I talked about taking protein to an endocrinologist and a therapist. The first one prescribed me a course of Ursofalk for the liver, the second said that there would be a problem with potency.
It must be understood that sports nutrition is a branch of sports medicine and dietetics. Like everything in the modern world, it does not stand still. Now it is fashionable to be healthy, so many people began to play sports, and accordingly are interested in sports nutrition (food supplements), which would affect the result. It is impossible to say unequivocally that sports supplements are harmful to health. In this case, a lot depends on the quality of the product and how well you adhere to the recommendations for use.
Among the wide range of food supplements, it is difficult for an ordinary person to determine a high-quality and truly useful product. The situation is complicated by advertising, which in most cases does not provide complete information about a particular product. Unfortunately, today there are few specialists who know all the nuances that sports nutrition has. This is all complicated by selfish motives, almost no seller will tell you honestly to the end about this or that supplement.
The biggest problem of newcomers, they wanting to imitate their jock idols, begin to consume not only sports nutrition, but and "chemistry" from which they are instantly carried away. You've probably noticed how your acquaintances, who recently looked like pimples, became huge like closets in a short time. It's all chemistry, it even happens that young people resort to anabolic steroids to be "like Schwarzenegger." This is incredibly harmful and dangerous.
Many novice athletes to take sports supplements are driven by the desire to imitate their idol. This is especially true among young people who have just started bodybuilding.
Trying to look like champions in a certain sport, amateurs do not take into account the genetic predisposition of the body and, without the slightest hesitation, blindly copy the training systems of professionals, and with them the means of recovery and nutritional supplements. At the same time, not every amateur, even if he has the financial capabilities, is able to keep up with the schedule of a champion for whom sport is making money.
The intrusiveness of beautiful advertising, which convinces us that without taking sports nutrition it is impossible to get a result in building muscle mass, forms the opinion among novice bodybuilders that supplements are a prerequisite for this sport. And therefore, novice athletes, instead of correctly approaching the issue of nutrition, training, as well as getting advice from a good specialist, are trying to find a magic supplement.
Currently, there is a lot of debate about the dangers and benefits of sports nutrition. What is better to take proteins or amino acids? There is no answer to this question. There are many different points of view, and there are even more myths. Common myths include the claim that all sports supplements are chemistry. But this is not entirely true, because there are protein supplements that are produced on the basis of natural products such as soy, eggs, milk.
Choosing what is better proteinor amino acids, you should remember organic chemistry from the school curriculum. Protein is made up of amino acids that are linked by chemical bonds. And an amino acid supplement is a degraded protein that is more digestible. This is the basis for choosing.
There are supplements that are nutritious and healthy. Their forms, that is, powder, tablet, concentrate, differ only in the rate of assimilation. But even the most effective supplement still cannot compete with traditional food. Everyone knows that it is difficult to find products on supermarket shelves that have not been genetically engineered. And milk for the production of protein is provided by a cow, which is stuffed with drugs that increase milk yield. But if you want, you can always find a healthy product, the main thing is to want it.
Given the level of education of doctors in the field of sports drugs, it is unlikely that a person should seriously expect a competent and reasoned answer from them. Most doctors will simply dismiss “don’t mess with”, “don’t,” “don’t recommend”. For them, the main thing is “no matter what happens,” so that there will be no complaints about them later. Therefore, the athlete is forced to conduct the search for truth and answers independently. This is not difficult to do, the main thing is not to be captivated by stereotypes about the mythical dangers of sports nutrition. And avoid the very common mistakes when the cause of unpleasant symptoms are not supplements, but their wrong choice or intake.
It is also not worthwhile to choose a place of purchase on the basis of "where is cheaper." Given the cost of imported sports nutrition, it is quite possible to run into a fake or expired product with an interrupted production date. In general, the small savings are not worth the risk.
Any new supplement should be taken gradually, starting at the lowest dosages. The ideal option would be to purchase small packages to assess the taste and reaction of the body.
What problems (in theory), due to various reasons, can a person experience when taking sports nutrition? Most of them are associated with the digestive system: heartburn, nausea, bloating, diarrhea, skin allergies.
As you can see, nothing fatal or particularly scary. But this is not something that can lead to the use of sports nutritional supplements. However, it is worth understanding that in 90% of cases, the cause of the problems is not sports nutrition, but its improper use or individual reactions of the body. Everything is the same that often happens when eating regular food.
There are only three reasons why sports nutrition can be harmful, not beneficial: individual intolerance or allergic reactions, improper use of drugs, low-quality products ... But talking about the dangers of sports nutrition, implying a load on the kidneys, liver, cardiovascular system and potency - in my opinion, is simply ignorant, because there is not a single scientific basis for this judgment. Information on the Internet in bulk. It is important to be able to filter it. In the field of fitness, health and sports, empiricism is the nail. How many people, so many opinions, but without facts, it's all slander.
There should be a measure in everything, absolutely in everything. After all, having come to the gym, we do not try to immediately lift hundreds of kilograms, we make the load optimal for our level. So here too, you need your own measure, foolishly you can go over it, and all sorts of allergic reactions can occur, from banal indigestion, and ending with something completely unpleasant. It must be remembered that ordinary sugar and salt has a lethal dose :) But sports nutrition is not harmful, and with loads it is not that useful, it is necessary. Protein is protein, the main resource in building muscle mass, vitamins, fats, amino acids, all this the body uses in a complex process called anabolism) So sports nutrition is definitely not harmful, but only if you drink everything in normal quantities, and not in horse doses )
Yes, eating a large amount of this food disrupts the work of the cardiovascular system.
In general, it is better not to eat such foods, unless of course you are an athlete.
