Show 1049: Do You Need a Gluten-Free Diet?
Years ago, doctors thought that celiac disease was incredibly rare among Americans. In this auto-immune condition, exposure to gluten found in barley, rye and wheat causes the body to attack the lining of the digestive tract. The damage that is done interferes with the ability of the intestines to absorb nutrients properly and that can lead to serious consequences indeed. In fact, people with undiagnosed or untreated celiac disease are twice as likely to die prematurely as other individuals.
Celiac Disease Is Not Rare:
Research over the past decade has shown that celiac disease is nowhere near as uncommon as doctors once thought. It is even becoming more common. Certain drugs may pre-dispose susceptible people to developing celiac disease.
Who Might Need a Gluten-Free Diet?
But now, with gluten-free food available in most grocery stores, it is far easier to follow the prescribed diet. Should people be eating gluten-free even if they don't have celiac disease?
For most people, it is important to see a doctor and be tested before starting a gluten-free diet. The diet could interfere with the accuracy of the test. And most people benefit from a dietitian's advice, since gluten hides in many foods where you wouldn't expect it.
Non-Celiac Gluten Sensitivity:
People who believe they react to gluten even though they don't have celiac disease might have non-celiac gluten sensitivity. But many do not. It can be a challenge to follow a gluten-free eating plan that is balanced and provides adequate nutrition.
Do you really need a gluten-free diet? If so, how do you ensure that it provides all the necessary nutrients?
