A few weeks ago I started testing the Fast Tract diet, I wanted to see how my body (most importantly my gut) responded.
After a few years of being on a low FODMAP diet it’s been a tricky shift in mindset, I find I am constantly checking the app on my phone, because I’ve had instances when I’ve eaten something without checking its fermentation point (FP) value. The Fast Tract diet uses a FP system which means the higher the FP value, the greater the chance at having symptoms.
Norm Robillard, Ph.D created the diet and identified five major carbohydrate groups that are hard-to-digest and are most subject to malabsorption, therefore are most likely to drive symptom and illness:
- Fructose, including polymeric forms (apples, oranges, banana, grapes, etc.)
- Lactose (milk, ice cream, etc.)
- Resistant starch (most potatoes, most rice, most grains, banana, pasta, etc.)
- Fibre (whole grains, bran cereal, legumes, supplements, etc.)
- Sugar alcohols except erythritol (diabetic and sugar-free snacks, etc.)
An example of where I made a mistake with the diet recently was consuming rice noodles; it turns out they have a high FP value. I don’t eat a lot of grains but if I do, I’ll eat rice or rice noodles and occasionally quinoa, but it seems quinoa is also a high FP food.
Other examples of high fermentation foods are legumes, dried fruit and fruit juices, squash, peas, parsnips and corn. Many foods have a moderate FP score, so the idea is to calculate and keep track of your points for the day and stick to a limited amount.
Some items on the Fast Tract diet list raised my eyebrows, what I’m referring to are items such as brie cheese, heavy cream and Skittles candy; these items have low FP scores. Given I suspect I have a leaky gut, I won’t be eating these foods on a regular basis as there are other considerations besides the fermentation potential of food, such as the potential inflammatory response certain foods can cause. I’ll continue to eat a wholefoods diet consisting of vegetables, herbs, fruit (probably only 1 serve a day), lean meat, poultry, fish, eggs, nuts, occasional small amounts of low FP grains and a little dairy here and there (small amounts of goats cheese, butter, parmesan and ghee). I’ll also continue to consume organic produce where possible to reduce the toxin burden on my body.
So has the diet worked for me? At this stage I’m on antimicrobial treatment; neem, berberine and allicin. I feel well and symptom free about 70% of the time, but the true test will be when I come off the antimicrobial treatment.
Unfortunately there is not much research on the Fast Tract diet. I attempted to find some original research and was unable to find any in relation to SIBO and IBS. However, I’m going to give it a try for at least a few months and I’ll report back to let you know my progress.
Has anyone else tried the Fast Tract diet for SIBO or IBS? Please leave a comment below and let me know how you went.
Yours in health,
