Food Sensitivity: Origin, Classifications, Signs, and Identification
In the realm of dietary sensitivities, food intolerances often go unnoticed compared to food allergies. However, they can significantly impact a person's health and quality of life.
Food intolerances are typically characterised by digestive system issues rather than immune system reactions, as is the case with food allergies. Symptoms of food intolerances can take a while to emerge, often persisting for several hours or even days, and may include bloating, excess gas, stomach pain, diarrhea, and nausea.
One of the most widespread food intolerances is lactose intolerance, which stems from a deficiency of the enzyme lactase needed to digest lactose, the sugar found in milk and dairy products. Similarly, people with celiac disease or gluten sensitivity cannot tolerate gluten, a protein found in wheat, barley, and rye.
Other common food intolerances involve certain fruits and vegetables or specific food chemicals in processed foods. For instance, fructose intolerance can be due to a lack of an enzyme or a protein that allows the body to absorb the sugar from the intestine. Sulfites, commonly found in wine, dried fruits, and some jams and jellies, can cause chest tightness, hives, diarrhea, and sometimes anaphylaxis in those with an intolerance.
The food industry often uses a variety of additives such as antioxidants, artificial colorings, flavorings, emulsifiers, flavor enhancers, preservatives, and sweeteners. While most of these additives do not cause problems for the majority of people, some individuals may react adversely to them.
It's important to note that diagnosing food intolerances can be challenging due to similar symptoms with food allergies and chronic digestive conditions like irritable bowel syndrome (IBS). A food diary, exclusion diet, skin prick test, or blood test can help in diagnosis.
In contrast to food allergies, food intolerances do not involve the immune system. Instead, they usually result in gastrointestinal symptoms and discomfort rather than immune reactions. This means that the severity of symptoms depends on the amount of the food ingested, unlike food allergies where even a small amount can trigger a severe reaction.
Here's a summary of common food intolerances:
| Food Type | Common Intolerance Cause | |-------------------------|-------------------------------------------| | Milk/Dairy | Lactose intolerance (lack of lactase) | | Wheat/Grains | Gluten intolerance or celiac disease | | Fruits/Vegetables | Food chemical sensitivity, FODMAP triggers| | Food Additives | Sulfites, dyes, flavorings |
Understanding food intolerances is crucial for maintaining a balanced diet and ensuring good health. If you suspect you may have a food intolerance, it's recommended to consult with a healthcare professional for accurate diagnosis and guidance on managing your diet.
- Celiac disease, a disease that concerns digestive health, affects those who cannot tolerate gluten.
- Food intolerances are characteristically linked to digestive system issues, in contrast to food allergies and their immune system reactions.
- Symptoms of food intolerances can emerge and persist for several hours or even days, such as bloating, excess gas, stomach pain, diarrhea, and nausea.
- Lactose intolerance, a widespread food intolerance, is due to a deficiency of the enzyme lactase needed for lactose digestion.
- People with celiac disease or gluten sensitivity, chronic-diseases in their own right, also struggle to tolerate gluten.
- Other common food intolerances may involve certain fruits and vegetables or specific food chemicals in processed foods.
- For example, fructose intolerance can be the result of a lack of an enzyme or protein that allows the body to absorb the sugar from the intestine.
- Sulfites, frequently found in wine, dried fruits, and some jams and jellies, can cause chest tightness, hives, diarrhea, and anaphylaxis in those with an intolerance.
- The food industry often relies on additives such as antioxidants, dyes, flavorings, emulsifiers, flavor enhancers, preservatives, and sweeteners.
- While most additives are harmless for the majority of people, some individuals may react adversely to them.
- Diagnosing food intolerances can be difficult due to symptoms being similar to those of food allergies and chronic digestive conditions like IBS (irritable bowel syndrome).
- A food diary, exclusion diet, skin prick test, or blood test can assist in diagnosing food intolerances.
- Unlike food allergies, food intolerances do not involve the immune system, typically causing gastrointestinal symptoms and discomfort.
- Symptom severity depends on the amount of the food ingested, unlike food allergies where even a small amount could trigger a severe reaction.
