A properly functioning digestive system is critical to good health. In fact, problems with the gastrointestinal (GI) tract can cause more than just stomach aches, gas and bloating, constipation or diarrhoea. GI issues may underlie chronic health problems that seem unrelated to digestive health, including autoimmune diseases such as rheumatoid arthritis and diabetes, skin problems, depression, PCOS and endometriosis, infertility, headaches and brain fog, heart disease (just to name a few).
​
So in the bigger picture, how can we deal with all that can go wrong “down there”? 

​In Functional Medicine we use a program that goes by the simple acronym of the ‘5Rs’: remove, replace, reinoculate, repair, and rebalance. When applied to various chronic health issues, the 5R program can lead to dramatic improvement in symptoms, and sometimes even complete resolution.
​
The 5R program:

1. Remove
Remove stressors: get rid of things that negatively affect the environment of the GI tract including allergic foods, 
parasites and potential problematic bacteria or yeast. This might involve using an  “Elimination Diet” to find out what foods are causing GI symptoms. It may also involve taking dietary supplements  or herbs to eradicate a particular bug
2. Replace
Replace digestive secretions: add back things like digestive enzymes, hydrochloric acid, and bile acids that are 
required for proper digestion and that may be compromised by diet, medications, diseases, aging, or other factors. 
3. Reinoculate
Help beneficial bacteria flourish by ingesting probiotic foods or supplements that contain the “good” GI bacteria 
such as bifidobacteria and lactobacillus species, and by consuming the high soluble fiber foods that good bugs like to eat, 
called prebiotics. 
PROBIOTICS are beneficial microorganisms found in the gut that are also called “friendly bacteria.” Use of 
antibiotics kills both good and bad bacteria. Probiotics in the form of supplements or food are often needed to 
help reestablish a balanced gut flora. Fermented foods, such as yogurt, miso, and tempeh are food sources 
of probiotics. 
PREBIOTIS are food ingredients that selectively stimulate the growth of beneficial microorganisms already in 
the colon. In other words, prebiotics feed probiotics. Prebiotics are available in many foods that contain a fiber 
called inulin, including artichokes, garlic, leeks, onion, chicory, tofu, and other soy products. Grains such as barley, 
flax, oats, and wheat are also good sources of prebiotics. Another good prebiotic source is a supplement called 
“fructo-oligosaccharide” or FOS.
4. Repair
Help the lining of the GI tract repair itself by supplying key nutrients that can often be in short supply in a 
compromised gut, such as zinc, antioxidants (e.g. vitamins A, C, and E), fish oil, and the amino acid glutamine. 
5. Rebalance
It is important to pay attention to lifestyle choices. Sleep, exercise, and stress can all affect the GI tract. Balancing 
those activities is important to an optimal digestive tract.
