Leprino has determined that native whey protein is generally recognized as safe (GRAS) based on scientific procedures in accordance with 21 C, F, R. Protein powder is essentially a supplemental form of protein (from now on we'll call them “protein supplements”). They are not standardized or regulated, and their composition varies widely. Not all protein powders are created the same way.
The different types can include whey protein isolates, whey protein concentrates, whey protein hydrolysate, casein, and plant-based powders. These supplements are made by extracting protein from animal or plant sources that range from dairy products, eggs, soy, peas, hemp or rice. In most cases, fiber, fats, vitamins, minerals, and natural carbohydrates are eliminated during processing. Many protein supplements also contain additives, flavors, and fillers.
When deciding if you could benefit from using a protein supplement, considering how much protein you need is an important factor. Most people can get enough protein through their diet without needing a protein supplement. In fact, many people tend to overdo protein when they add a protein powder supplement to their daily food intake. However, protein supplements may be useful for people who have difficulty meeting their daily protein needs, especially those with higher protein needs, such as those receiving treatment for cancer, those who are recovering from a burn, injury or surgery, patients with chronic diseases, and athletes.
Protein supplements may also be helpful for those who don't have the appetite to eat the amount of protein foods they need. To reiterate, there are many circumstances that justify the use of protein supplements. In addition, many people choose to use a protein supplement out of preference, convenience, and many report a feeling of fullness with the use of protein supplements. While meeting daily protein needs and combining them with meals and snacks has clear advantages, consuming additional protein isn't necessarily better.
The body doesn't always use excess protein efficiently, whether from food or supplements, and more protein doesn't equal more muscle. In addition, excess protein can cause excess calories. The extra calories, whether from protein, fat, or carbohydrates, are stored in the body. Excess protein can be especially problematic if it displaces the necessary carbohydrates and fats in the diet.
In addition, protein supplements can cause digestive disorders such as bloating, gas, stomach cramps, and diarrhea. But are these supplements really safe? In addition to proteins, these powders often contain potentially harmful chemicals, and some are even contaminated with toxins and metals. How can that be? Under the Dietary Supplement Health and Education Act, the FDA does not regulate any dietary supplement, including protein powders, to ensure that it is safe or effective. Supplements don't need to be tested to make sure they contain what the labels say they contain.
Research has shown that many dietary supplements sold in major drugstore chains, health food stores, and respected online stores don't contain what they should contain, or contain ingredients that aren't listed on the label. TL; DR Whey protein is safe for the vast majority of people. The FDA accepts whey protein as a safe food, based on both evidence and its ubiquitous use. Evidence doesn't suggest that whey protein decreases bone mass or causes kidney problems, at least in healthy populations.
Whey protein is safe for the vast majority of people. Unfortunately, there isn't much research on how specific types of proteins (whey, casein) affect kidney health. Most people can get enough protein through the foods they eat, but there are circumstances in which supplementing with protein powder may be beneficial. Calcium and vitamin D are important for maintaining bone health; whey protein didn't affect the levels of either.
Casein protein has long been known as slow or nocturnal protein because of its relatively slower travel time compared to. This characterization means that the FDA has determined that whey protein causes no harm when used as intended. Protein powders are forms of protein powder that come from plants (soy, peas, rice, potatoes, or hemp), eggs, or milk (casein or whey protein). .
