How to reduce symptoms associated with food intolerances

“I can’t leave the house because I’m so worried that I won’t be able to find a toilet in time and sometimes I become so full of gas that I look like I’m pregnant. I need help!”

Diarrhoea, constipating, bloating, flatulence. The side effects of food intolerances can be annoying for some and utterly debilitating for others. Melanie McGrice and her team understand. They specialise in providing the dietary guidance and compassionate support that can help women manage eating and improve symptoms caused by food intolerances.

And more and more women need that help.

Food intolerances in Australia

Both the rates and severity of allergies and food intolerances are on the rise.

  • Australia has one of the highest rates of allergy and intolerance in the world
  • Research by allergy physician Dr Mullins and his team discovered that there has been a 4 fold increase in food allergies and intolerances over 12 years, with a 5 fold increase in hospital admissions for anaphylactic reactions

Although there is still no conclusive proof, research suggests that delayed introductions of allergenic foods like eggs, food processing methods and the ‘hygiene hypothesis’ (which proposes that reduced exposure to infections in early life impacts upon the gut microbiome to increase allergy and intolerance risk) may all play a role in the dramatic rise in allergies and intolerances. Furthermore, it seems that Small Intestine Bacterial Overload (SIBO) may be responsible for many cases of food intolerances.

What’s the difference between an allergy and intolerance?

A food allergy is when the immune system identifies a normally healthy food as toxic to the body. Allergies can cause symptoms such as swelling of the face and throat, abdominal pain, vomiting, dizziness and even collapse. In contrast, food intolerances don’t cause an immune reaction, but may result in similar side effects, including nausea, vomiting, flatulence, constipation and diarrhoea. Food intolerances are often caused by the body being unable to digest a food or nutrient as well as usual.

What can be done?

The answer to both food intolerances and allergies is careful identification of the key triggers, followed by elimination of those ingredients. Both allergies and intolerances can improve with time, so it’s essential to have periodic reviews with your dietitian or allergy specialist to determine if the food can be reintroduced.

Unfortunately food restrictions can leave your diet lacking key nutrients so it’s essential to ensure that food allergies and intolerances are properly diagnosed and banned foods are replaced with alternative solutions. SIBO can also impact your body’s ability to absorb nutrients leaving you nutritionally deficient and tired.

These are the top questions on the minds of women visiting our nutrition and wellness centre in Melbourne to learn more about the effects of diet on food intolerances and allergies.

Do I need to eliminate these foods permanently?

Many allergies and intolerances improve over time. It is recommended that you undertake periodic testing with your dietitian or allergy specialist to see if your allergy has improved. Foods which trigger intolerances can often be reintroduced after a period of gut rest, and once gut health has been revitalised.

What causes food intolerances?

Small Intestinal Bacterial Overgrowth (SIBO) is a common cause of food intolerances. Food intolerances can also be caused by gastro, gastrointestinal surgery or traveller’s diarrhoea.

What is SIBO?

Our gut is the home of millions of bacteria which are used for digestion, immunity and good health. However, most of these bacteria should live in the large bowel. When they sneak into the small bowel which is used for the absorption of nutrients, they can cause diarrhoea, nausea and difficulty absorbing nutrients. This condition is known as Small Intestinal Bacterial Overgrowth (SIBO) and is usually treated with strong doses of antibiotics and nutritional supplements.

Should I take probiotic supplements?

Probiotic supplements can be helpful for many women with food allergies and intolerances to help restore gut health, however it’s essential to ensure that you use the right type of probiotic and follow the instructions on the label; probiotic supplements that are outside of their use-by date or not kept at the right temperature are just a waste of money.

Can’t I just cut the food out and not worry about reintroducing it?

You can as long as the foods eliminated are replaced with foods that are nutritionally equivalent such as replacing milk with yoghurt. However, increasing the variety in your diet will make it easier for you to eat out and enjoy a variety of foods without fear of embarrassing repercussions.
