What is a food intolerance?

From bloating and IBS to migraines and joint pain, food intolerance causes misery and uncomfortable symptoms for thousands of people. But what is a food intolerance and why is it estimated to affect nearly half the UK population?

Food intoleranceFood intolerance can occur when your body has difficulty digesting certain foods. When this occurs over time, large food particles (proteins) may enter the blood stream.

A reaction manifests when these partly-undigested food particles enter the bloodstream and are treated as foreign substances – antibodies ‘attack’ the food in question and generate an inflammatory response. The body produces food-specific IgG antibodies as a defence against certain ingredients that may not agree with you.

Over time, food intolerances may build up and persist in the system. Just like if you stopped brushing your teeth, you would expect to see a build-up of plaque, bad breath and discolouration which may lead to problems, such as tooth decay. Food intolerances can build up in the same way if the root cause hasn’t been rectified.

Food intolerance vs food allergy

Many people confuse an intolerance with an allergy, but the two are very different. Potentially life-threatening and quite rare, the immune response that causes an allergic reaction (IgE) happens soon after consuming specific foods, such as peanuts or shellfish and it affects around 2% of the adult population.

A food intolerance, on the other hand, can provoke an IgG reaction and is estimated to affect around 45% of the UK population*. The body’s abnormal reaction to certain foods can cause gastrointestinal upsets such as irritable bowel syndrome (IBS), bloating, diarrhoea, as well as migraines, fatigue and joint pain. Although not life-threatening, the uncomfortable symptoms can have a major impact on a person’s quality of life.

The rise in food intolerances

People may often wonder whether it’s simply our awareness into food intolerances which is increasing, or whether food intolerances are actually on the rise.

There are a number of likely reasons why there is an increase in food intolerances, some examples are:

  • Farming practices
  • Environmental pollution
  • Processed foods
  • Food additives
  • Antibiotic and painkiller usage
  • Stress levels

What can be done about it?

Many people who suffer from food intolerance symptoms might be given the all-clear by their doctor yet strongly suspect that food is the roost cause of their problems. If you know someone who is experiencing some unexplained symptoms – such as feeling unusually tired more often, bloating regularly, or suffering from migraines without any known cause – perhaps it could be worthwhile taking a closer look at their diet.

Here at Lorisian, the business to business brand of YorkTest, we believe there are a number of options that individuals can choose when they suspect that they may be reacting to a food or foods that they are eating. These are:

  • Do nothing

Of course, ignorance is sometimes bliss, but when it comes to health, it’s always better to seek help. If a food intolerance is the symptom cause, it will persist or may even develop in the body over time if neglected.

  • Choose to remove foods from their diet by second guessing

It can be second nature to attempt to guess which foods are contributing to certain symptoms. Bread, for example, might be assumed to be the culprit – however, there’s a variety of potential trigger ingredients, such as wheat, gluten and even yeast. As a result, foods might be cut from the diet unnecessarily.

  • Seek support from a dietician or nutritional therapist and try an elimination diet and challenge method

This method strips diet back to basics by eliminating large food groups for a period of time then slowly reintroduce specific foods and monitor symptoms accordingly. Unfortunately, this method can be laborious, and it can be difficult to pinpoint exactly which combination of ingredients provoke reactions.

  • Take a food intolerance test to identify their food triggers and fast-track their elimination diet

A credible IgG food intolerance test is used as a strategy for identifying foods to which a person may be sensitive. Lorisian has found that the average person with positive results typically reacts to 4 to 5 ingredients. This shows there could be some unsuspecting ingredients that may be challenging to find by simply removing ingredients that feel suspect.

Food for Thought

We often hear the phrase ‘you are what you eat’, raising our awareness of what we put in our bodies will not only benefit the clients that we treat, but will also benefit ourselves as therapists, I decided it would be good idea to share some key facts related to nutrition with you on a regular basis.

What is “nutrition”?

Nutrition is the science of food, the nutrients in foods and how the body uses those nutrients. The science studies the process by which living organisms acquires all things that are necessary for them to live and grow. Nutrients are defined as substances that the body is unable to make on its own. These nutrients include minerals, vitamins and macromolecules. It includes the process of ingestion, digestion, absorption, metabolism, transport, storage and excretion of those nutrients. It also includes the environmental, psychological and behavioral aspects of food and eating. The six classes of nutrients include: carbohydrates, fats, proteins, vitamins, minerals and water. To summarise nutrition consists of Diet which is the foodstuffs which are taken into the body; and metabolism what happened to the food when it enters the body and the chemical changes that occur.
What is cholesterol? What are the two main types?
Cholesterol is a fatty substance which is found in the blood. It is mainly made in the body and plays an essential role in how every cell in the body works. Unfotunately too much cholesterol in the blood can increase the risk of cardiovascular disease. Proteins carry cholesterol around the body and these combinations of cholesterol and proteins are called lipoproteins. The tow main types of lipoproteins are:
Low- denstity lipoproteins (LDL) which is the harmful type of cholesterol
High-density lipoproteins (HDL) which is a protective type of cholesterol
It is important to note that some people can have high blood cholesterol even thought they eat a healthy diet. for example it is possible to inherit a condition called familial hyperlipidaemia (FH). A common cause of high blood cholesterol  levels is eating too much saturated fat.
What are the types of fat found in food? What are trans fats?
There are two main types of fat found in food – saturated and unsaturated. Both contain the same amount of calories but to ensure you maintain a healthy diet, you need to cut down on food high in saturated fat and eat foods that are rich in unsaturated fat. Eating a diet high in saturated fat will cause the level of cholesterol in the blood to increase over a period of time, if excessive amounts of cholesterol are in the body the risk of heart disease and its associated conditions is greatly increased. On average a man should eat no more that 30g of saturated fat a day, and an average woman no more than 20g a day.
Trans fats are chemically altered vegetable oils. They are artificially produced in a process called hydrogenation which turns liquid oil into solid fat.  They are used because they are cheap, adding bulk and they have a neutral flavor and give products a long shelf life. They are of no nutritional value at all. They can be found in processed foods, foods containing hydrogenated vegetable oil and also occur naturally, but at very low levels for ex dairy products. Trans fats can raise cholesterol levels in the blood, this is why it is recommended that no more that 2% of the energy (calories) is made up of trans fats.
What is the medical importance of Omega-3 fatty acids?
The medical importance of Omega-3 fatty acids are that they reduce inflammation and may help lower the risk of chronic diseases such as heart disease, cancer and arthritis. Omega-3 fatty acids are highly concentrated in the brain and appear to be important for cognitive (memory and performance) and behavioral function. It is interesting to note also that infants which do not get enough Omega-3 fatty acids from their mothers during pregnancy are at risk of developing vision and nerve problems.
