The manner of nourishment possesses a significantly broader meaning than just taste... It also encompasses a broad range of micro and macro components that, upon digestion, enter our organism, where they are appropriately utilized as an energy source.
Why the utilization of protein supplements is beneficial
This type of supplement is ideal for an active individual who needs to consume a significant amount of protein but lacks the time to prepare a full-fledged meal or is unable to consume it. Supplements are a dietary supplement and should not be used in excess. There are many types of supplements that are characterized by different absorption times, carbohydrate and fat content, and source of origin. The most popular kind of this kind of food is the protein-derived protein concentrate. All variants are naturally characterized by a high content of amino acids, making them excellent for building muscle mass. An important advantage is also the ease of preparation. To prepare a portion of this supplement, simply add water or milk, mix, and the meal is ready. However, how much should a portion of this kind of supplement be? Manufacturers often include pre-measured scoops, suggesting that one scoop is enough for one serving. Is this the optimal amount, or does it depend on individual needs? The most important factor is the overall need for protein. If we are providing the right amount of protein daily, then the size of the portion is secondary.
The optimal amount of protein per portion
A research team from the famous Dr. Stuart Phillips lab set out on a mission to discover the answer to the question, how much protein should be in a single serving. Study participants engaged in strength training, after which they received consecutive protein portions containing 0, 10, 20, or 40 grams of protein. After consumption, muscle anabolism was evaluated, as expressed by muscle protein synthesis. With increasing protein quantity in the portion, a progressive increase in anabolism was noticed. However, the most significant increase occurred when consuming 20 grams of protein. Although no significant difference was noted between the 20 and 40-gram portions, a minimal increase was detected physiologically. As a result, many individuals, upon analyzing the study results, conclude that the optimal protein serving is around 30 grams. It is also worth noting that study participants were men who averaged 86 kg in weight. Individuals with higher weight and more muscle mass may potentially benefit from a larger protein portion.
Is it possible to exceed the limit of protein consumption in diet?
Protein constitutes an essential and natural component of our daily diet, making it very difficult to provide it in a way that could harm our health. Any excess that we supply will be utilized as energy, converted into urea, and expelled from the body. Unlike fats and carbohydrates, our body doesn't have a protein reserve. Yes, this role is partly fulfilled by muscle tissue, but it can only absorb amino acids in a limited amount. If we provide an excess of building blocks, it must be removed. Dr. Olivier Witard presented this issue in his 2014 work, where he administered similar doses of whey protein to patients as in the previously mentioned study, but this time investigated the production of urea and the oxidation of leucine. If you decide to supplement your diet with a protein supplement, it's best to use doses that provide around 30g of protein. If we provide less, we don't allow for the maximization of muscle protein synthesis, and if we provide more, we expose ourselves to a significant loss of valuable amino acids.
