What is gastritis? 

Gastritis, to put it simply, is the inflammation of the lining of the stomach. It has many causes and common symptoms include nausea, stomach pain, and loss of appetite. For most people, gastritis is not serious and improves quickly with treatment. Left untreated, however, gastritis can cause stomach ulcers and stomach bleeding. In some rare cases, chronic gastritis can lead to stomach cancer. 

Diet is one of the best ways of managing gastritis. Many people with gastritis find that eliminating certain foods from their diet improves their symptoms. This is particularly true for people with food allergies. If you find that a certain food or food group makes your symptoms worse, avoiding this food will make you feel better. That said, there is no one gastritis diet because the foods that cause symptoms for one person may not cause them for someone else. Finding what foods work for you is therefore a delicate process of trial and error.

Can protein powder cause gastritis?

There is no evidence that protein supplements cause gastritis. That said, the average protein supplement can cause your symptoms to flare up. If this is something you have experienced, do the following: 1) eliminate the supplement from your diet for a few days to see if your symptoms subside 2) keep reading to learn why protein supplements can aggravate gastritis symptoms.

Gastritis can affect your ability to absorb nutrients from food and lead to nutritional deficiencies. To counteract this, it is crucial to consume lots of protein, ideally 1-2 grams per kilogram of body weight daily.

Eating this much protein can be challenging for some individuals. Firstly, certain protein-rich foods are restricted for people with gastritis. Secondly, a loss of appetite is a common symptom, making it difficult to consume sufficient amounts of food alone. This is where protein supplements can be beneficial. Incorporating protein powder into your diet offers a convenient means of increasing your protein intake and ensuring you meet your daily requirements. Not all protein powders are created equal, however.

Most protein powders are not safe for someone with gastritis. Do not be fooled by clever marketing.

First of all, many protein powders contain emulsifiers, stabilizers, thickeners, sweeteners, and flavors, all of which are notorious for causing uncomfortable side effects and long-term damage to the gut. This is especially true for individuals with gastritis, so it is absolutely crucial to opt for a protein powder that consists of a short list of simple ingredients. Keep reading to learn more.

Why drink wholesome

drink wholesome is additive-free.

One of the reasons why we make the best protein powder for gastritis is that we do not use food additives. Even in small quantities, additives can trigger a range of side effects including bloating, constipation, diarrhea, gas, and stomach pain. This happens because additives bear no resemblance to real food, making it challenging for your body to effectively digest them. Consequently, they either draw water into the intestines, which causes diarrhea, or sit in your gut and feed your gut bacteria. As they eat, gut bacteria produce gas, causing bloating and stomach pain, and impeding the passage of food through the colon, which can lead to constipation.

The long-term implications of consuming food additives are even more alarming. Over time, additives can disrupt crucial regulatory pathways in the intestines, thereby contributing to the development of inflammatory bowel disease (IBD) and other systemic inflammatory disorders. Emerging research suggests that food additives, especially artificial sweeteners, may also trigger disruptions to the gut microbiome (the collection of microorganisms that help you digest food), which can have profound consequences on gut health.

Here is a list of the most common food additives in protein powder:

acacia gum, acesulfame potassium, artificial flavors, aspartame, carrageenan, cellulose gum, dextrin, dextrose, erythritol, gellan gum, guar gum, gum arabic, inulin, locust bean gum, “natural” flavors, maltodextrin, rice syrup solids, soy lecithin, silica, sucralose, sunflower lecithin, xanthan gum, xylitol

the alternative:

Protein Matrix Comprised of (Whey Protein Concentrate,  Whey Protein Isolate, Calcium Caseinate, Micellar Casein, Milk Protein Isolate, Egg Albumen, Glutamine Peptides), Polydextrose, Sunflower Creamer (Sunflower Oil, Corn Syrup Solids,  Sodium Caseinate, Mono- and Diglycerides, Dipotassium Phosphate, Tricalcium Phosphate, Soy Lecithin, Tocopherols), Natural and Artificial Flavor, MCT Powder (Medium Chain Triglycerides, Nonfat Dry Milk, Disodium Phosphate, Silicon Dioxide), Lecithin, Cellulose Gum, Salt, Yellow 5, Sucralose, Acesulfame Potassium, Papain, Bromelain.

*This is the actual ingredient list of one of the best-selling protein powders in the United States.

drink wholesome is dairy-free.

Another reason why we make the best protein powder for gastritis is that we do not use dairy-based proteins. In contrast, many protein powders contain whey and casein, which are derived from the production of cheese and yogurt. Unfortunately, both of these protein sources can present digestive challenges, especially for individuals with lactose intolerance. Lactose intolerance, which is common among individuals with gastritis, is the inability to fully digest lactose, the sugar in dairy. As previously mentioned, the fermentation of partially digested food by gut bacteria results in the production of excessive gas and accompanying discomfort.

drink wholesome is made with real foods.

A final reason why we make the best protein powder for gastritis is that we do not use protein concentrates or isolates. In contrast, the vast majority of protein powders contain one or both of these protein sources, which have been stripped of everything except the protein content. They are labeled as “pea protein” or “whey protein,” as opposed to “peas” or “whey.”

The manufacturing process behind protein concentrates and isolates involves rigorous mechanical and chemical procedures. In some cases, chemical solvents such as hexane are used to extract the protein from the original food source. Consequently, the end product looks nothing like real, natural food.

Your digestive system is designed to process naturally occurring foods, not synthetic imitations. Feeding yourself anything other than real food therefore has the potential to cause side effects. While the long-term effects of consuming processed foods like protein isolates are still being studied, emerging research suggests that such foods can significantly alter the composition of your gut microbiota, leading to permanent gut damage.

Beyond its primary role in food digestion, the gut acts as a protective barrier against harmful pathogens, plays a vital role in educating your immune system, and exerts influence—both directly and indirectly—over a wide range of physiological functions. Disturbances to the delicate balance of the gut microbiome have thus been strongly associated with the development of various chronic diseases. In light of this link, I would steer clear of protein powders made with protein concentrates and isolates if I were you.

Instead of protein concentrates or isolates, we make the best protein powder for gastritis gut with egg whites and almonds. The egg whites undergo a simple process of pasteurization and drying, while the almonds are roasted, lightly pressed to reduce oil content, and then ground. These minimally-processed ingredients offer an easily digestible and gut-friendly alternative to protein concentrates and isolates.

If you do not have any sensitivities or allergies to eggs, egg white protein is an excellent choice for your gut health. Egg whites are low in fiber, low in FODMAPs, naturally alkaline, and boast the highest protein digestibility-corrected amino acid score (PDCAAS) among all whole foods. Our customers have shared exceedingly positive feedback, reporting fewer digestive issues when consuming egg white protein powder than with any other protein source.

For individuals who cannot consume eggs, our vegan almond protein powder is an appealing alternative. Unlike protein concentrates or isolates, almonds are rich in healthy fats, fiber, and essential nutrients like calcium and vitamin E. We favor almonds over other minimally-processed plant protein sources due to their notable gut-friendly properties. Research suggests that almonds possess prebiotic characteristics, supporting the diversity and composition of the gut microbiome and ultimately promoting improved gut health.

In summary, our protein powders, whether made with either egg whites or almonds, are made with minimal processing to prioritize gut health. Regardless of which one you choose, you can expect a high-quality product that nourishes your digestive well-being.
