Understanding Gluten-Free Diets

What is Gluten?

Gluten is a type of protein found in grains such as wheat, barley, and rye. It is responsible for the elasticity and texture of dough, giving bread and other baked goods their chewy texture. Gluten is not inherently harmful to most people, but it can be problematic for those with celiac disease or gluten sensitivity.

Celiac disease is an autoimmune disorder where the ingestion of gluten leads to damage in the small intestine. Gluten sensitivity, on the other hand, is a less well-defined condition where individuals experience gastrointestinal and extra-intestinal symptoms after consuming gluten-containing foods, but without the presence of celiac disease or wheat allergy.

In a gluten-free diet, foods containing gluten are avoided to prevent adverse reactions in individuals with celiac disease or gluten sensitivity. This can lead to potential nutrient deficiencies if not properly addressed through alternative sources.

Why Go Gluten-Free?

  • Gluten is a protein found in wheat, barley, and rye
  • It helps dough to rise and gives bread its chewy texture
  • Some people have an autoimmune reaction to gluten, causing inflammation and damage to the small intestine
  • This reaction is known as celiac disease
  • It affects about 1% of the population
  • Other people may have a sensitivity or intolerance to gluten, which can cause digestive symptoms
  • A gluten-free diet is recommended for those with celiac disease or gluten sensitivity/intolerance
  • However, many people choose to follow a gluten-free diet for other reasons, such as weight loss or because they believe it is healthier
  • It is important to note that a gluten-free diet is not appropriate for everyone and should only be followed under the guidance of a healthcare professional.

Gluten-Free Diet Restrictions

A gluten-free diet restricts the consumption of gluten, a type of protein found in certain grains, such as wheat, barley, and rye. Individuals who follow a gluten-free diet do so because they have been diagnosed with celiac disease or non-celiac gluten sensitivity. In celiac disease, the ingestion of gluten leads to damage in the small intestine, while in non-celiac gluten sensitivity, the body responds to gluten as if it were a foreign substance, causing inflammation and other symptoms.

Gluten-free diets require individuals to avoid all foods containing gluten, including bread, pasta, cereals, and baked goods. Many processed foods may also contain hidden sources of gluten, such as modified food starch and maltodextrin. To ensure that they meet the dietary restrictions, individuals following a gluten-free diet must carefully read food labels and seek out gluten-free alternatives for foods that are traditionally made with gluten-containing ingredients.
