2026美国消费者对膳食纤维与全谷物的认知调研报告

February 2026 METHODOLOGY The International Food Information Council (IFIC) commissioned an online survey among U.S. consumers tomeasure knowledge, attitudes, and beliefs about carbohydrates, including dietary fiber and whole grains.One thousand and six adults ages 18 years and older completed the online survey from October 22-30, 2025, The Bayesian confidencelevel for the survey sample (n=1006) is 3.5, whichisroughly equivalent to a margin oferror of±3.1 at the95%confidence level.Callouts of statistically significant results are included whereappropriate on slides displaying results.Something is statistically significant if the result cannot beattributed SUGGESTED CITATION:International Food Information Council (IFIC). IFIC Spotlight Survey: Americans' Perceptions of Fiber & Whole Grains. February 2026. EXECUTIVE SUMMARY Carbohydrates are a cornerstone of a healthy diet, supplying a primary source of energyand key nutrients. Two key indicators of carbohydrate quality—dietary fiber and whole grains—play critical roles in digestive health, metabolic function, and long-term chronic disease prevention. Yet despite decades of dietary guidance, fiber and whole grain intakein the United States remain chronically low. Most Americans consume only abouthalfofthe recommended daily fiber intake, a pattern that has persisted fordecades. Fewer than ThisIFIC Spotlight Survey: Americans’ Perceptions of Fiber & Whole Grains, illustrates thechallenge of overcoming America’s long-standing fiber gap. Nearly one in three Americanssay they consume fewer than 20 grams of fiber per day, well below the recommended 14 grams per 1,000 calories. Overall, nearly three in ten (29%) report consuming under 20grams of fiber per day while 37% are unsure of their daily intake. Importantly, zero percent Encouragingly, awareness of the benefits of fiber and whole grains is high. About seven inten Americans believe fiber and/or whole grains are good for their health, and they aretwice as likely to say carbohydrate-rich foods can be part of a healthy diet than to say theycannot. While fruits and vegetables are most often identified as top fiber sources, grain Barriers persist, including uncertainty about which foods contain fiber, concerns about thecost and taste of high-fiber foods, and which information on food packaging to look for.Together, data from thisIFIC Spotlight Surveypoint to opportunities to provide clearer,more consistent messaging for carbohydrate foods, especially those with higher wholegrain and fiber content, to address our decades-long nutrition shortfall while aligning with K E Y F I N D I N G S Nearly one in three Americans say they consume fewerthan 20 grams of fiber per day, well underrecommended amounts. Top barriers to increasing fiber intake includeknowledge, cost, and taste of high-fiber foods. Survey results show both readiness and challenges related toincreasing fiber intake. While one in three Americans (33%) report nobarriers, others cite practical and knowledge-based obstacles. Notknowing which foods contain fiber is the most common barrier (30%),followed by cost (27%) and taste (26%) of high fiber foods. Additionalchallenges include cooking or preparation time (24%) andinconvenience (17%). Importantly, no respondents indicated that they Compared with established dietary guidance, a substantial shareofAmericans do not meet recommended fiber intake levels or lackawareness of their fiber consumption. Current guidancerecommends 14 grams of fiber per 1,000 calories (about 21 to 38grams per day depending on age and sex). In thisIFIC SpotlightSurvey, 29% report consuming less than 20 grams of fiber per day,while 37% report that they do not know how much fiber they More than half of Americans say that at least somecarbohydrate-rich foods can be part of a healthy diet. Nearly half of Americans say fruits and/or vegetables arethe best source of fiber. Survey results indicate generally favorable, though mixed, perceptionsof carbohydrate-rich foods. One-quarter of Americans (25%) believethese foods can be part of a healthy diet, while 30% believe only somecan, and 12% believe they cannot. Notably, Americans are twice aslikely to view carbohydrate-rich foods as compatible with a healthydiet (25%) as to view them as incompatible (12%). However, uncertaintyremains: one in three Americans are either unsure whethercarbohydrate-rich foods can be part of a healthy diet (14%) or do notknow which foods are considered carbohydrate-rich (19%), Following fruits and vegetables, which are identified as the bestsources of fiber by 46% and 48% of Americans, respectively,perceptions of fiber sources vary widely. Grain foods are cited by 41%,followed by nuts and seeds (39%) and cereals (38%). Notably, 34%identify fiber supplements as a top source, surpassing several whole- food options such as legumes (30%) and breads (26%).Misconceptions persist, with 24% selecting meat or seafood and 19% K E Y F I N D I N G S One in
