Common Types of Food Intolerance

Gluten Intolerance

It is a broad term which includes all kinds of sensitivity to gluten. A small proportion (less than 0.5% of the population) of gluten intolerant people will test positive to a Celiac disease test, and so are called Celiacs.

Symptoms of Gluten Intolerance & Celiac Disease

  • Gastrointestinal problems (diarrhea, flatulence and bloating, etc)
  • Headache
  • Mouth ulcers
  • Weight gain or weight loss
  • Poor immunity to disease
  • Skin conditions such as dermatitis & Eczema
Common Types of Food Intolerance
Dairy Sensitivity

Dairy Sensitivity

It is estimated that up to 75% of the world’s population is lactose intolerant to some extent, though very few people (less than 3%) are allergic to Casein (the protein found in milk). This is usually detected in babies but can remain undiagnosed until later.

  • Lactose intolerance is caused by a deficiency of the enzyme, lactase, needed to digest lactose (milk sugar). Lactose-free and lactose-reduced milk and milk products are available at most supermarkets. Soy milk and other products may be helpful to these people.

Symptoms may include:

  • nausea
  • diarrhea
  • bloating
  • flatulence
  • gastro- intestinal malabsorption
  • Casein Intolerance a milk protein allergy and is likely to be an inherited gene.

Common allergy symptoms include:

  • itchy skin conditions
  • GI (gastrointestinal)
  • respiratory problems

Fructose Sensitivity

Fructose Malabsorption is common and affects about 30% of people. Fructose malabsorption occurs when certain special cells (epithelial cells) on the surface of the intestine are not available to assist the digestive process.

Fructose Intolerance
is a rare genetic condition where the enzyme for breaking down fructose is not produced. With fructose intolerance, it is vital to observe a strict fructose-free diet. Fructose Intolerance affects less than one in 10,000 people.

Symptoms of Fructose Sensitivity:

  • Flatulence
  • Bloating
  • Diarrhea
  • Fatigue
  • Low iron or other nutrient deficiency
  • Sugar craving
Fructose Sensitivity

Yeast Sensitivity

Yeast infection is extremely common. Up to one in three or 35% of people have yeast infections at any time. The Candida yeast organism is normally kept in check by the human immune system. But sometimes, particularly when the immune system is compromised, it will multiply rapidly and overwhelm our systems leading to a variety of unpleasant symptoms – collectively known as Candidiasis or yeast infection.

Hormonal changes in the body, as with hormone therapy, pregnancy and the contraceptive pill can trigger a yeast infection in people whose immune systems are under challenge, for example stress. Repeated courses of antibiotics can also be a trigger.

Symptoms of Yeast Infection:

Yeast infection carries the widest spectrum of symptoms of any food sensitivity:

  • skin problems like ringworm
  • gastro-intestinal problems
  • lethargy
  • headache
  • breathing difficulties
  • mood swings
