Fibre is an essential part of a healthy diet; however, the average adult in Canada consumes far less than the recommended 21–38 g of dietary fibre per day. (1) A moderate intake of dietary fibre has been associated with maintaining overall health. (1) This includes soluble fibre, which is fermented by beneficial bacteria in the gut. Soluble fibre enhances gastrointestinal health, function, and regularity, while also lowering the glycemic index (GI) of foods.
Many high-fibre foods and supplements are high in FODMAPs (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols). These are small carbohydrates and sugar alcohols that some people have difficulty digesting because of their inability to absorb them from the small intestine and their rapid fermentation in the gut. (2) For people with irritable bowel syndrome (IBS) and other digestive dis- orders, eating FODMAPs can result in abdominal discomfort, bloating, gas, diarrhea, or constipation. Because FODMAPS are found in many common foods, such as legumes, wheat, milk, apples, broccoli, cauli-flower, onion, garlic, and sweeteners, it can be challenging for people with digestive disorders to get enough fibre through their diets.
FibreSense is free of FODMAPs. It contains partially hydrolyzed guar gum (PHGG), a natural water-soluble, non-digestible dietary fibre made from the guar plant seed. PHGG is produced by controlled partial enzy- matic hydrolysis of guar gum, but maintains the same metabolic nutri- tional and analytical properties. Guar gum is fermented more slowly in the intestinal tract than some other prebiotic fibres, making it easily tolerated. Evidence shows that a low-FODMAP diet is an important part of managing functional digestive disorders, such as IBS. (2)
PHGG stimulates gut microflora and helps relieve symptoms of IBS, improving normalizing stool condition in either constipation and diarrhea, in both adults and children. A randomized, double-blind, placebo-controlled study found that supplementing adult IBS patients with 6 g of PHGG per day for 12 weeks significantly improved abdominal bloating and gas. (3) Another study found that taking 5 g or 10 g doses of PHGG per day for 12 weeks can help improve gastrointestinal symptoms and quality of life for up to three months. (4) A similar study on children aged 8–16 found that a 5 g dose of PHGG per day for four weeks was 38% more successful at reducing symptoms of IBS than a placebo. It also showed a tendency to support normal bowel movements. (5)
Constipation affects 25% of Canadians and increasing dietary fibre intake is often the first step in managing it. (1) This includes soluble fibre, which enhances gastrointestinal health, function, and regularity. A meta-analysis of 15 clinical trials found that a daily 5–7 g dose
of PHGG significantly reduced incidences of constipation without causing adverse effects. Researchers also found that PHGG was equally effective at reducing constipation as laxatives. (6)
PHGG also supports healthy blood sugar balance by lowering the glycemic index of food. A 12-month clinical study revealed that participants who took 6 g of PHGG with each meal significantly lowered their post-meal blood glucose levels, in addition to both fasting and post-meal insulin levels. Furthermore, 50% of glucose- intolerant participants were observed to be normal glucose
tolerant after three months of supplementation. (7)
