The amount of fiber in one’s diet can significantly impact human health conditions. It supports the functions of the digestive system and is linked to a reduced risk of various ailments, including certain cancers. Against this backdrop, the “fibermaxxing” trend, which involves striving for a regular adequate intake of dietary fiber, is gaining traction across social media platforms.
Jennifer Lee, a researcher from the Human Nutrition Research Center on Aging at Tufts University, offered insights into the effectiveness of this phenomenon. Her specialization lies in examining how the gut microbiome and overall intestinal health influence metabolic processes throughout a person’s lifespan.
Numerous studies indicate that a lack of fiber contributes to the development of metabolic and cardiovascular diseases, such as diabetes and obesity. When individuals consume insufficient dietary fiber, the body attempts to compensate for this shortfall with other forms of calories, frequently carbohydrates or fats, which often results in weight gain.
Furthermore, fiber deficiency is associated with elevated risks for specific cancer types, including colorectal cancer, as well as tumors affecting the breast and prostate glands.
Adults are generally advised to consume between 22 and 34 grams of fiber daily, contingent on their gender and age. Lee suggested a simpler calculation method: aiming for approximately 14 grams of fiber for every 1,000 kilocalories consumed in the diet.
Dietary fibers are categorized into two primary groups: soluble and insoluble. The former dissolves in water, which aids in slowing down the digestive process. This, in turn, prolongs feelings of satiety, stabilizes blood sugar levels, and lowers cholesterol content. Foods rich in this type of fiber include apples, bananas, avocados, broccoli, legumes, and oatmeal.
Insoluble fiber is much less easily processed by the body. This leads to an increase in the volume of intestinal contents, thereby facilitating its passage and helping to ward off constipation. It is abundantly present in whole grains, nuts, and seeds.
According to the expert, an optimal diet should ideally include twice as much insoluble fiber as soluble fiber. Therefore, if the daily target is 30 grams, roughly 20 grams should come from insoluble sources, with the remaining 10 grams sourced from soluble fibers.
If meeting the necessary fiber volume strictly through food proves challenging, supplements can offer assistance. However, increasing intake must be done gradually. A sudden surge in dietary fiber content can trigger uncomfortable symptoms such as bloating, constipation, or diarrhea.
