The effects of a low fiber diet could be irreversible and hereditary

Compared to previous generations, especially to our grandparents, many of us associate current health problems with a number of differentiating factors: increased stress levels, hectic lifestyles and poor nutrition. A recent study conducted by researchers from Stanford, Harvard and Princeton Universities supports a part of this hypothesis, pointing out that a low fiber diet helps reduce the number of beneficial microorganisms in the human colon causing irreversible and hereditary damage. Read on to find out what you should not exclude in both yours and your family’s diets. 

It is no secret that current diets include a large number of simple, low-fiber fatty carbohydrates, in contrast to complex carbohydrates that break down in the colon, so, to assess how each of these diets affects the human body, researchers studied the evolution of the intestinal microbiome of 10 laboratory animals. Thus, for 6 weeks, laboratory mice - very similar in organism with humans - were fed with complex carbohydrates rich in fiber, and subsequently divided into two groups: a control and a trial group. The first received the same fiber-rich diet throughout the study, while the other was fed a drastically reduced amount of fibers. Although, at first, the structure of beneficial micro-organisms in the colon was the same for both groups, the mice receiving fewer fibers began to show changes in the intestinal microbe, as it became increasingly poor in beneficial microorganisms. Even after returning to a fiber-rich diet, these mice have remained different from the control group, showing that poor nutrition affects our body on the long run, even after changing the negative dietary habits. 

Furthermore, to show to what extent dietary change has contributed to the reduction of beneficial microorganisms, the study measured the number of taxonomic units in the colon and found that in the case of those who underwent regimen changes, their number decreased by 60% ( From 208 to 84), compared to only 11% in the case of mice that did not show food changes. The resumption of a fiber-rich diet has helped the mouse population to recover from the loss of taxonomic units, bringing the percentage to 33%, but demonstrating, at the same time, that poor fiber diets leave major scars on the microbe, affecting both us and future generations. 

What can we do to ensure we stay healthy? The researchers encourage the shift from high-carb diets to fiber-based diets and recommend eating foods such as artichokes, avocados, beans, pears, broccoli, lentils etc. However, in the context of the current lifestyle, specialists know that it is impossible to take up the entire amount of fiber in the diet and therefore recommends fiber-based supplements. 

Of these, Sinergin, the prebiotic that combines 10 grams of inulin and oligofructose, is the perfect choice for people who want to keep their colon happy and weight and blood pressure under control.
