Food intolerance is a digestive system response that occurs when the body has difficulty breaking down certain foods. Unlike food allergies, which involve the immune system, food intolerance typically leads to uncomfortable symptoms such as bloating, gas, and stomach cramps. Common triggers include lactose, found in dairy products, and gluten, found in wheat. People with food intolerance may need to avoid specific foods to prevent symptoms. Keeping a food diary can help identify problematic items. It's important to consult a healthcare professional for proper diagnosis and management, as symptoms can sometimes overlap with other conditions like Irritable Bowel Syndrome or Celiac Disease.
