Rising incorporation of these fibers in functional foods and supplements for targeting gut health will also add to the industry expansion.
Insoluble Dietary Fibers Market Growth Drivers and Restraints
Increasing support from regulatory authorities in several countries via health claims for encouraging food manufacturers to promote health benefits offered by insoluble dietary fibers will prove beneficial for the industry development. However, the adverse effects of excessive dietary fiber intake leading to gastrointestinal distress and nutrient malabsorption may slow down the industry growth.
COVID-19 Impact
The COVID-19 pandemic had positive impact on the insoluble dietary fibers market due to the heightened consumer awareness about the importance of healthy diets and strong immune system. The influx of lockdowns and travel restrictions led to the growing preference for home cooking and baking, adding to the higher consumption of whole grains as well as products rich in insoluble dietary fibers. The rising demand for natural, organic, and minimally processed foods also contributed to the increasing adoption of insoluble dietary fibers to promote digestive health during the pandemic.
Insoluble Dietary Fibers Market Trends
The ongoing R&D efforts within the food industry for finding innovative ways of incorporating insoluble dietary fibers into broader range of food products as well as maintaining taste and texture will drive the market growth. For instance, in July 2023, a study led by Brazilian researchers showed that diet comprising suitable amounts of inulin, which is a soluble fiber abundant in chicory roots, influences the length as well as other macroscopic characteristics of intestines. Several research activities are also underway to explore encapsulation technologies for masking the taste and texture of insoluble dietary fibers to turn them more palatable.
Insoluble Dietary Fibers Market Analysis
Insoluble dietary fibers market size from the cellulose segment is projected to grow substantially between 2023 and 2032, attributed to the rising importance of cellulose in human nutrition to counter diverticular diseases. As per Canadian Society of Intestinal Research, diverticular disease occurs in nearly 5% of the Western adult population younger than forty years of age. Cellulose plays a crucial role in maintaining digestive health as it adds bulk to stool, promotes regular bowel movements, and prevents constipation. The growing innovations, such as cellulose nanofibers and cellulose nanocrystals to match the growing applications in nanotechnology and biomedicine will also prove favorable for the segment growth.
The cereals & grains segment accounted significant share of the insoluble dietary fibers market in 2022 and will witness expansion through 2032, due to the higher intake of breakfast and bakery products worldwide. According to Glanbia Nutritionals, around 28% of consumers reach for cereals as morning snacks. Cereals and grains rich in insoluble dietary fibers are beneficial for weight management and help in preventing overeating. The surging emphasis on promoting gut microbiota along with lowering the risk of developing colon disorders, such as diverticulosis and diverticulitis will also considerably contribute to the segment expansion.
North America insoluble dietary fibers market is expected to witness over 6.5% CAGR through 2032, driven by the higher healthcare spending and the stringent government regulations related to nutritional supplement facts labels. The surging health concerns related to food habits has led to the rising burden of nutritional and gastrointestinal disease incidences, further driving the need for nutritional supplements.
