FOOD SENSITIVTY

Tired of diet restrictions?

We can help you reintroduce the food you love.

Are you struggling to find the root cause of your sensitivities or solve a complicated puzzle?

Conditioned Food Avoidance & Sensitivity may be a missing piece.

The Conditioned Food Avoidance & Sensitivity Trap (C-FAST) can devastate your physical and mental health, making you feel:

  • Frustrated: by an endless cycle of elimination diets.
  • Hopeless: that you will be on a restricted diet forever.
  • Scared: to eat.
  • Angry: that you cannot enjoy food like other people.
  • Alone: because your restricted diet makes socializing difficult.
  • Exhausted: because your life revolves around food.
  • Confused: about what you should and should not eat.
  • Worried: that you are not getting adequate nutrition.

I created the Conditioned Food Avoidance and Sensitivity Trap to show how people get caught in restriction and worsening sensitivities.

When you are stuck in the C-FAS Trap:

  • Food becomes a trigger for stress.
  • You think about food and your symptoms more than you want to.
  • You are caught in a never-ending cycle of wondering what will make you sick, then feeling sick.
  • Your food sensitivities keep getting worse.

Recognize this vicious cycle and break out.

Conditioned food avoidance and sensitivity have become a growing challenge for so many of the patients I see. Wendy Busse has captured the core elements of this behaviour, and most effectively, her treatment methods are on point and patients benefit.
I highly recommend Wendy’s approach.

The brain’s primary role is to protect us and keep us safe. In the interest of doing this, it does not take many adverse experiences before the brain starts to anticipate what could be a threat to its safety. For patients who experience digestive symptoms after eating, food very quickly becomes a source of threat that can trigger activity in the sympathetic nervous system. While in this state of “fight or flight,” the body deprioritizes digestion, which can lead to a host of symptoms including altered motility, nausea/vomiting, abdominal pain, or indigestion that may be falsely attributed to the nutrient itself. This can lead to a cycle that reciprocally reinforces food/nutrients as dangerous, even though there are often multiple factors that contribute to postprandial symptoms. The Conditioned Food Avoidance and Sensitivity Trap (C-FAST) eloquently captures this cycle.

People living with food allergies, sensitivities and digestive health conditions often see food as something to be fearful of, and/or avoid altogether.  This makes sense given the simple pairing of a specific food or food group with a closely timed physical reaction (conditioning). However, over time, fear and avoidance can take over the brain-gut connection and interfere with one’s ability to live their best life. The antidote to conditioned food avoidance is a slow and structured period of food re-introduction, led by an expert dietitian or behaviorist.  In this model, it is important for the patient to come prepared with a flexible and curious mindset, a sense of confidence in their ability to “re-train the brain” and an optimism that with the right skill set, you can master your nutrition and overall health.

My interest for this topic developed over the last thirty years of food sensitivity counselling. I saw the devastating impact this vicious cycle had on my client’s mental and physical health. Raising awareness about the Conditioned Food Avoidance & Sensitivity Trap has become the driving force of my career.
