Connection of food fibre amount and human health risks

Food fibre is the new black in functional nutrition, range of plant based fibre sources have been examined by the European Food Safety Authority (EFSA) in the last decade and claims like “improving digestion”, “lowering blood glucose” and “lowering cholesterol levels” can be placed on the food products with high fibre content. The World Health Organisation is stressing the importance of fibre with a minimal daily requirement of at least 25 grams. Healthy nutrition programmes run by advanced healthcare providers (like NHS in UK) include advice on eating at least 5 portions of plant based food a day, which provides at least 20 grams of dietary fibre a day.

Systematic review published in Lancet included data from 185 prospective studies and 58 clinical trials with 4635 adult participants. Observational data suggest a 15–30% decrease in all-cause and cardiovascular related mortality, and incidence of coronary heart disease, stroke incidence and mortality, type 2 diabetes, and colorectal cancer when comparing the highest dietary fibre consumers with the lowest consumers. Risk reduction associated with a range of critical outcomes was greatest when daily intake of dietary fibre was between 25 g and 29 g. 

This data corresponds to results obtained in our screening held on long-lived mice model – one of 1033 compounds tested was well-known prebiotic inulin, used as supplement and food ingredient to increase overall dietary fibre consumption. Inulin has shown an increase in average lifespan 16%, which is one of the top performing compounds among screened. Just as in the research cited above inulin seems to have systemic effect on several systems like microbiome and detoxification. Inulin itself is one of the most researched food fibre, and one of very few has confirmed claims of improving digestion, postprandial glucose and “bad” cholesterol. 

In Longevica paradigm food fibres are thought of as microbiome modulators and vessels to removing toxins disarmed by liver and excreted in digestive tract with bile. Inulin in addition is highly bifidogenic, meaning promoting growth of specific “lactic acid producing bacteria” well known as probiotics.
