In my clinical nutrition experience, when a client needs protein supplements, I usually use a whey protein isolate powder, even though it is of animal origin. I like the fact that whey protein contains all nine amino acids that your body needs to give in order to be able to use all of the protein. Whey protein is easily absorbed and can be used by the body, even after surgery or other stressful events.
In the past, nutritionists refer to the nine amino acids as "building blocks of protein". Then they began to call them "essential amino acids" because the body can not produce these building blocks alone, but must fully win the foods we eat. Recently, experts have improved their admiration for the nine amino acids and have been called "indispensable amino acids" (IAAs). Three of the most important IAAs – leucine, isoleucine and valine – are called "branched chain amino acids" that are believed to help improve and develop muscle and even blood sugar control.
Another advantage of the whey protein isolate is that although it is made from milk, it does not contain lactose, an enzyme in milk that irritates people's digestive tract. Thus, whey powder works well in weight-loss patients who are lactose intolerants.
Since it seems that my bariatric surgery seems to be vegetarian or want to avoid milk-based proteins, I suggest protein-insoluble powders from soybeans. I talked to my patients about several new vegetarian protein powders in the market that they could use as an alternative. These vegetarian protein components can easily be digested and absorbed before and after surgery. They may be nutritionally similar to the whey protein powder, although their IAA profiles vary depending on their processing.
Other Plant Powders
Sometimes I recommend other, less-known protein products to my patients to supplement their protein intake:
Hemp protein. Hemp is a nutritional plant whose oil is rich in polyunsaturated fatty acids ("good" fats). The seeds of hemp contain all nine IAAs and are similar to proteins in the human body, facilitated and digested and assimilated. In addition, hemp protein is rich in fiber, serving 8 grams of natural fiber per serving to help constrain and meet the protein needs. (The hemp protein is perfectly legitimate from the "male" part of the marijuana plant that has no mood swings.)
Brown rice protein, which is fairly sufficient, carefully extracted from protein from brown rice. Although rice is often ignored because the protein profile of the amino acids is deficient, rice powder usually complements the missing L-amino acids that meet their profile. Many vegans rely on this allergen-free, fine, and high-quality protein powder when finishing their exercise programs.
Yellow pea protein. Protein powder made from yellow peas (Pisum sativum) is an easy-to-absorbent, allergenic 100% pure protein source, which is also fairly certain that it is not genetically modified. Protein Ingredients and Shakes Easy to Add Without Changing Taste
Manufacturers are currently discussing whether protein from other protein sources such as flaxseed and rape can be achieved.
Thinking About Vegetarian Protein Powders
As more and more people seek alternatives to animal protein powders, it is important for suppliers to offer high-quality alternatives. Despite the fact that high-quality hemp and rice protein powders have been seen, producers must be sure that each new product contains the right amount of essential amino acids. Otherwise, the body will not be able to pick up these new powders or use the grams of the proteins listed on the label.
"Protein Digestibility Corrected Amino Acid Score" (PDCAAS)
If you are trying to figure out whether the protein powder is full and if the proteins listed on the label are available to your body (i.e., if "absorbed "or" bioavailable "), you must first find the PDCAA score. PDCAAS is a capability of a protein product that is able to provide the level of each of the IAs required by the human body. Registered dietitian or other healthcare professional can calculate your PDCAAS or, if you know the IAA quantity of the protein product in question, you can search for an online "PDCAAS calculator". (Note: If the manufacturer did not indicate the quantities of IAA on the label or on the website and if you do not know or will not tell these numbers, go ahead – the quality of your products is suspicious.)  More protein may not be better.
When preparing smoothies, I give advice on super concentration of protein content. This means that you can not add more than 1 pitch or more than 30 grams of protein to each drink. Your body may be absorbed more than once than one, but a high concentration of protein can dehydrate the body. In addition, too many proteins in patients with stomach bypass surgery may at one and the same time increase the unpleasant phenomenon called "stomach dump" or rapid gastric lavage if the ingestion of food consumes the stomach as quickly as it enters the small intestine, largely undigested.
The unnecessary protein you eat – but your body does not need – it contains just as many extra calories.
Protein powders are an excellent way to supplement your diet if your protein intake is low, but always contact your doctor or a registered dietician to find out what the right protein is for you – that's different for each person.
