Food intolerance




Experiencing gut problems? You could be having a reaction to the food you’re eating.

One thing is for sure since and even before Hippocrates: What we eat affects our health!

Equally, even if you eat healthily you might have some intolerance to certain food. Food intolerance means either the body can’t properly digest the food that is eaten, or that a particular food might irritate the digestive system. Symptoms of food intolerance can include nausea, gas, cramps, belly pain, diarrhoea, irritability, or headaches. And if you suffer from those symptoms, a leaky gut may be a big part of the problem. Leaky gut occurs when there is damage to the lining of the intestinal tract making it more permeable to substances that should not cross the delicate lining. When your digestive tract is inflamed by food sensitivities, bad bacteria, or dysbiosis, your protective mucous layer breaks down. in turn, this inflammation is thought to be one of the main contributors to leaky gut.

If you have some food intolerance (nearly everyone), you need to understand which ingredients create inflammation in your body and you can book a simple food intolerance test. This is particularly important if you suffer from a leaky gut as this could lead to health issues.


What is a Food Intolerance?

Usually, food intolerance occurs when you have an enzyme deficiency or reaction to certain chemical components in foods. It is important to stress that food Intolerance is generally not life-threatening but can make you feel not your best and impact your quality of life.

Someone who is suffering from food intolerance can have a delayed reaction, several hours after eating some specific food. The best advice would be to have a test to find out if you are intolerant to a food. Then, there is a process to eliminate the ingredient from your diet that can then be reintroduced gradually.

Anti-Inflammation diet

It is a fact that lifestyle and diet play a major part in ageing and inflammation. Thanks to my work, I am always looking for ways to refine my diet and natural approach for anti-ageing. Well, ageing is a fact and that is an ineluctable path. However, we have a choice in how we can affect our health and slow our ageing process. This being said, all of the products out there, promises and lifestyle philosophies can certainly be overwhelming.

One day, I came across a “new diet” called “Anti-Inflammatory Diet”.  I was intrigued because from my research about inflammation, I know it affects our overall health and the ageing process.

What is body inflammation?

When body inflammation is good, it fights off foreign invaders, heals injuries and mops up debris. However, when it’s bad, inflammation ignites a long list of disorders. Such as ageing, migraine, skin & hair problems, depression, asthma, arthritis, diabetes, atherosclerosis, blindness, cancer, and quite possibly even, mental illness.

Simply put, our immune system responds to an injury or disease with inflammation. This is a normal, reparative reaction that is necessary for healing. White blood cells, including granulocytes and macrophages, are the “first responders” to sites of infection and injury. They emit waves of chemicals that can kill germs outright, and protein messengers called cytokines to carry out a wide array of duties.


Yes, Not all Inflammation is Good

If inflammation persists beyond its intended purpose, the immune system mistakenly attacks normal cells. And then, the process that ordinarily heals instead becomes destructive. As a matter of fact, chronic inflammation is the root cause of many serious illnesses.

The good news is that lifestyle choices can help. Following an anti-inflammatory diet and lifestyle is one of the best ways to reduce chronic inflammation and consequently optimise ageing and our overall health.

Can Food cause inflammation?

Food intolerance could be very strongly linked to your gut health. The inability to break down certain foods effectively can heavily impact the delicate balance of good bacteria within the gut and, by extension, the entire enteric endocrine system. This could explain the wide variety of symptoms related to food intolerances, like acne, headaches, and fatigue for instance.

Food reactions can happen to anybody and in fact, affect millions of people. Food allergies are a life-threatening immune response that differs from food sensitivities and intolerances.

Usually, food allergies appear in childhood, but sensitivities and intolerances often develop later in life. This is typically due to a weakening of the intestinal lining that can lead to a leaky gut. Consequently, a leaky gut allows for the passage of food particles, bacteria, viruses and these can trigger inflammation.

Also, food allergies often get diagnosed via blood tests and/or finger-prick tests, pinpointing your personal food sensitivities or intolerances require a different test.

If you suspect you have a food sensitivity or intolerance, here’s what you need to know.


Food allergies, food intolerances and food sensitivities

The main difference is that food intolerances or sensitivities are not life-threatening. In those cases, your immune system considers a particular food as an aggressor. Consequently, your metabolism thinks it needs to produce more antibodies to protect you. While the immune system plays a role in both food sensitivities and food allergies, the food reaction will recruit different immune cells and then lead to a different immune response and resulting symptoms.

For allergies, IgE antibodies send messages to other immune system cells that cause an allergic reaction or anaphylaxis, which can cause you to go into shock and can be fatal. on the other hand, with food sensitivities, the body produces IgG antibodies, which is not life-threatening but has a detrimental impact for a long period of time if not dealt with.

Furthermore, food intolerances predominantly affect the digestive system and can lead to inflammation with various effects on your health. We should note that intolerances are usually more specific. Whereas food sensitivities can often pertain to a wide range of foods.

In addition, intolerances and sensitivities are often related to the dose you take. If in a small amount you might be fine but at larger quantity, you will feel it.

Sometimes you just need less of that food or to eat it less frequently, depending on how your body reacts to it. As well, resting, sleeping, and stress management can all come into play in how our gut expresses food sensitivities.

Finally, while food intolerance and sensitivity are similar, you might have more severe symptoms if you’re intolerant to a food.


Food Tests


The distinction between food sensitivities, intolerance and sensitivities have now been presented. I will therefore go back to my story. In my case, I needed to know what food items were affecting my health

In order to find out my intolerance to some food, I simply took a test. Consequently, I found out that I was intolerant to yeast, Egg white, Almonds, Cashews, Hazelnuts and Sunflower Seeds. Many of these foods I consume regularly all year round and now I had to stop eating them. Well, the good news is that I had to stop eating them for a period of 3 months only… And, what a relief!

Though, the main relief is that I also noticed an improvement in my health as I was suffering from some chronic headaches around my eyes and now that was gone. I have been to an ophthalmologist many times and there was nothing wrong he told me. As soon as I stopped eating my inflammatory foods there was no more pain. If only I knew sooner that these headaches and other symptoms were related to food intolerance would have made my life more agreeable.

These symptoms can be avoided through avoidance of foods we’re intolerant to. Along with adding both probiotic and prebiotic foods to our diets. It is important to understand the amount of a specific food that can be managed by your body. And most importantly take better control of our own health.
