Dr. Oz: Gluten allergy symptoms and best protein powders for weight loss

Dr. Mehmet Oz discussed gluten allergy symptoms and the best protein powders for weight loss on the June 11 episode of the Dr. Oz Show ("The 5 Hidden Signs You Have a Gluten Allergy").

Dr. Oz said many people suffer from gluten sensitivity or allergy and aren't aware of it, mistakenly believing their weight gain, migraines, or depression is due to other health problems.

"Gluten allergy symptoms are notoriously difficult to recognize because they sneak up on you," he said.

Gluten Allergy and Sensitivity Linked to 55 Different Diseases

Dr. Oz's guest was Dr. Amy Myers, an expert on gluten allergy and sensitivity and author of the upcoming book, The Autoimmune Solution.

Dr. Myers said about 55 different diseases are associated with gluten intolerance and as many as one in two people unknowingly suffer from gluten sensitivity. The symptoms of gluten allergy include:

  • Weight gain
  • Irregular bowels (gas, constipation or diarrhea)
  • Skin rash
  • Joint pain
  • Brain fog.

Dr. Myers said a gluten allergy attacks your immune system, which causes chronic inflammation and weight gain. The reason why many people miss the signs of gluten sensitivity is because most doctors think it's associated only with gut issues, such as stomach pain or diarrhea.

But gluten sensitivity attacks the joints, skin and immune systems — in addition to the gut. So if you experience chronic migraines, brain fog, depression, or weight gain, those could be hidden signs of gluten sensitivity, even if you don't have digestive issues.

Celiac disease is an autoimmune digestive disorder that prevents the intestines from absorbing nutrients properly. As a result, a person with celiac disease can experience vitamin deficiencies and become malnourished if they ingest gluten. They also suffer the most common symptoms: severe abdominal pain, bloating, and digestive problems. Gluten sensitivity is not the same as celiac disease, but its symptoms can be just as traumatic.

Gluten is a protein found in wheat and other grain products and is what gives bread its chewy texture. Gluten is used in a surprising number of foods, such as soy sauce, bacon bits, blue cheese, beer and flavored coffee.

Fortunately, eliminating gluten from your diet can immediately cure gluten sensitivity. As a side benefit, many people who stop eating gluten experience weight loss. On previous episodes of the Dr. Oz Show, neurologist Dr. David Perlmutter and cardiologist Dr. William Davis discussed the many health benefits of a gluten-free diet.

Dr. Perlmutter, author of Grain Brain, said a low-carb, gluten-free diet prevents dementia and Alzheimer's, while Dr. Davis, author of Wheat Belly, said eliminating gluten promotes weight loss and reverses type 2 diabetes and heart disease.

Best Protein Powders For Weight Loss

On a separate segment, Dr. Oz said protein powders are a great weight-loss tool, but warned that some brands contain more calories than listed on their labels, and are even contaminated with lead.

Dr. Oz's guest was Dr. Tod Cooperman, president of Consumer Lab, which tested 16 popular protein powders. The results showed that some brands contain less protein and more carbs and calories than stated on their labels, which is horrible news for those are interested in weight loss.

Fortunately, there are a few top-notch protein powers that received Consumer Lab's seal of approval:

As a guideline, Dr. Oz said it's best to buy protein powders with as few ingredients as possible.
