Food Intolerance, What Are the Symptoms and What to Do

Food intolerance symptoms

Do you suffer from unexplained digestive issues, constant skin problems, or always feel tired?

This could be a sign that your body is not agreeing with something you’re eating. Many people around the world have food intolerances, and many don’t know it, thinking it’s just stress or the hustle and bustle of daily life. Identifying food intolerances can be the secret to feeling better and more active. In our London clinic of nutrition, we have helped many people i the last 10 years or so. 

Main Signs and Symptoms of Food Intolerance

Food intolerance can manifest in various ways and affect your health differently. Identifying them is the first step towards finding a solution. Here are some examples of symptoms:

Digestive Issues: Such as bloating, gas, heartburn, constipation, and diarrhoea.
Respiratory Issues: Runny or congested nose may be related to what you eat.
Skin Problems: Acne, eczema, and unexplained rashes could be due to specific foods.
Neurological Symptoms: Headaches and migraines may be linked to diet.
Tiredness: Feeling very tired or lacking energy after eating certain foods.

 

What to do if you suffer from one or more of the symptoms above and don’t know the cause?

If you are suffering from the symptoms above and you don’t know the reason or any conventional treatment is not working anymore, maybe you should look at your diet. The best approach is to do the Food Intolerance Test guided by a nutritionist to identify foods that don’t agree with your body. Knowing how your body reacts to certain foods can change your life for the better. You can take control of what to eat and avoid it. It is a life change to know exactly what causes the symptoms you suffer. The food intolerance test is easy to do, available worldwide (we can send it to your home), and helps you find out which foods are harming you.

How to test for food intolerance?

The test is simple, requiring just a small prick on the finger and a small amount of blood. You can do it at home or with our nutritionist in the London clinic. Thus, anyone can take the first step towards improving their health, no matter where they are.

What is the Difference Between Food Intolerance and Food Allergy?

Food Intolerance and Food Allergy

DIFFERENCES BETWEEN FOOD INTOLERANCE AND FOOD ALLERGY

What is food allergy and food intolerance?

Food allergy

The immune system’s reaction (defence of the body) against something (allergen) that seems strange, usually proteins that, can be derived from food, dust mites, pollens and animal hair.

Food intolerance

The difficulty of the body to digest a specific food is usually due to a lack of any relevant substance, such as digestive enzymes. It can be due to metabolic diseases, intoxications and other disorders. 

Body response:

Food allergy

Immediate, exaggerated, abnormal

Food intolerance

Reactions are delayed and occur several hours or days after ingestion

Quantity of substance to cause adverse reaction

Food allergy

Minimum quantity is needed and the body will react every time you eat the food.

Food intolerance

It may depend on the amount of food you eat and level of intolerance to cause any symptoms.

Symptoms

Food allergy

In general: cramps, vomiting, diarrhoea, stool bleeding, skin rash (urticaria), respiratory system (wheezing), and even more severe such as glottic oedema and anaphylactic shock (pressure drop with loss of consciousness), as well as general symptoms such as difficulty in gaining weight and growth.

Food intolerance

In general: gas, diarrhoea, bloating, heartburn, constipation, migraine, eczema, joint pain

Tests to detect

Food allergy

Blood test or skin test

Food intolerance

Blood test

Antibodies involved

Food allergy

IgE (Immunoglobulin E)

Food intolerance

IgG (Immunoglobulin G)

Treatment

Food allergy

Exclusion of the food or substance in combination with mediterranean diet.

Recommendations: a diet with minimally processed foods and rich in foods that support natural detox (prefer organic and nutrient-rich diet – avocado and pomegranate are sources of glutathione, a natural detoxifier). Peppermint to reduce histamine, ginger to improve GI symptoms, and turmeric to improve digestion and intestinal permeability. Label reading. Completion of a food diary correlated with symptoms.

If symptoms disappear, progress to a gradual reintroduction diet with medical supervision.

Food intolerance

The elimination diet is recommended for 4 to 12 weeks. If the patient has not undergone food sensitivity testing – the standard exclusion diet for sensitivity-causing foods (more restrictive) can be used. The nutritionist will guide you on how to eliminate and re-introduce the foods you are intolerant. In some cases, depending on the degree of the intolerance, it’s enough just to reduce the frequency and quantity consumed. If gastrointestinal symptoms are present the nutritionist may suggest a Low FODMAP Diet.

Frequently asked question: if I am intolerant to cow’s milk, should avoid all dairy?

Some individuals might be intolerant to cow’s milk but they can tolerate milk products like yoghurt and cheese as they contain less concentration of the proteins that cause intolerance. 

Types of food that cause allergy or intolerances

Allergy

Food components that cause allergy the most are cow’s milk, eggs, soy, wheat, crustaceans, citrus fruits, peanuts and nuts.

Intolerance

Food components that cause intolerance the most are cow’s milk, gluten, yeast, eggs, and nuts.

At the Raquel Britzke Clinic in London, there are Food allergy and Food intolerance tests to detect allergy or food intolerances with a small sample of blood. Knowing the differences and making an early diagnosis is of utmost importance to the health and quality of life of the patient.

In the food intolerance test, we analyse 200 types of food. Our allergy test panel includes the most common foods and environmental substances like dust, mites, pollen, etc.
