Feeling Sluggish? Could It Be a Food Intolerance?

Struggling with bloating, fatigue, or skin issues? You could have a food intolerance. Learn about common triggers like lactose, gluten, and FODMAPs, and discover how to identify and manage them.

Feeling Sluggish? Could It Be a Food Intolerance?

Feeling sluggish, bloated, or experiencing unexpected skin reactions? You could be dealing with a food intolerance. Unlike allergies, which trigger a swift and severe immune response, intolerances often cause subtler, yet persistent, symptoms. This guide explores common food intolerances, their telltale signs, and how to navigate this dietary challenge.

Common Food Intolerances

  • Lactose: This sugar found in dairy products can be difficult to digest for those lacking the lactase enzyme.

  • Gluten: A protein in wheat, barley, and rye, gluten can cause digestive discomfort, fatigue, and even skin issues in sensitive individuals.

  • Histamines: These compounds are abundant in aged cheeses, fermented foods, and certain fruits. Histamine intolerance can lead to headaches, hives, and a runny nose.

  • FODMAPs: This acronym stands for Fermentable, Oligosaccharides, Disaccharides, Monosaccharides, And Polyols. These short-chain carbohydrates can trigger gas, bloating, and diarrhoea, especially in those with Irritable Bowel Syndrome (IBS).  

  • Food Additives: Artificial sweeteners, preservatives, and food colourings can trigger reactions in some individuals, leading to headaches, nausea, and skin rashes.

Food Intolerance Symptoms

While symptoms can vary, common indicators of food intolerance include:

  • Digestive Distress: Bloating, gas, diarrhoea, constipation, nausea, and stomach cramps.

  • Skin Issues: Rashes, eczema, and itching.

  • Headaches and Migraines: Particularly after consuming trigger foods.

  • Fatigue and Low Energy: Feeling sluggish and tired, especially after meals.

  • Joint Pain: Aches and stiffness in the joints.

  • Brain Fog: Difficulty concentrating and remembering things.
