Fiber Surges in Popularity as U.S. Consumers Shift Focus

U.S. consumers are now embracing the health benefits of fiber, marking a significant shift from their recent fixation on protein. According to market research firm Mintel, the number of new products featuring high or added fiber has surged this year. This trend is evidenced by a growing presence on social media, where countless videos tout the advantages of dietary fiber and offer creative recipes to incorporate it into daily meals.

PepsiCo’s CEO, Ramon Laguarta, has voiced his belief that fiber could become as central to consumer diets as protein has in recent years. During a recent investor call, he remarked, “Consumers are starting to understand that fiber is the benefit that they need.” As a result, a new trend called “fibermaxxing” has emerged, with individuals seeking to meet or exceed the recommended daily fiber intake.

Understanding Fiber and Its Benefits

Unlike the appeal of protein, fiber is less glamorous. It is a carbohydrate found in plant-based foods that the human body cannot digest. Fiber plays a crucial role in supporting gut health by feeding beneficial bacteria and aiding the movement of food through the digestive system. Debbie Petitpain, a registered dietitian nutritionist and spokesperson for the Academy of Nutrition and Dietetics, noted that “Folks don’t want to talk about it at a dinner party,” highlighting the stigma surrounding this essential nutrient.

Fiber is categorized into two types: soluble and insoluble. Soluble fiber dissolves in water, forming a gel-like substance that nurtures gut bacteria. It can be found in oats, peas, beans, apples, and carrots. In contrast, insoluble fiber does not dissolve and helps with food passage through the digestive tract, prevalent in whole wheat flour, popcorn, nuts, and green beans. According to the American Heart Association, dietary fiber may lower cholesterol levels, regulate blood sugar, and promote feelings of fullness, which can assist with weight management. Furthermore, fiber intake has been linked to a reduced risk of heart disease, diabetes, diverticulitis, and colon cancer.

With the increasing popularity of GLP-1 weight loss medications, there has been a renewed interest in fiber, as these drugs naturally slow digestion, which can lead to constipation. Petitpain mentioned that similar spikes in fiber interest have occurred during the rise of low-carb diets like Atkins and keto.

Recommended Fiber Intake and Sources

Many people in Western nations are not consuming enough fiber due to diets low in fruits, vegetables, and whole grains. The U.S. Department of Agriculture recommends that adults consume 14 grams of fiber for every 1,000 calories consumed, equating to about 25 grams for women and 38 grams for men daily. Research indicates that Americans generally consume only about two-thirds of this suggested amount.

To put this in perspective, one cup of raspberries contains about 8 grams of fiber, while a banana offers 3.2 grams. Other notable sources include half a cup of avocado with 5 grams and one cup of lima beans containing 13.2 grams. For instance, Fiber One cereal provides a remarkable 18 grams of fiber in just a 2/3-cup serving.

To boost fiber intake, experts recommend selecting breakfast cereals with at least 5 grams of fiber per serving and topping them with fruits like bananas or berries. Choosing whole-grain breads with at least 2 grams of fiber and incorporating grains such as brown rice, whole-wheat pasta, and quinoa can also be beneficial. The Mayo Clinic suggests adding wheat bran to baked goods and aiming for five or more servings of fruits and vegetables daily.

While fiber is crucial for health, rapid increases in intake can lead to discomfort, such as gas and bloating. Petitpain advises a gradual increase in fiber consumption alongside increased water intake. “You’re feeding gut bacteria a food, and you can’t break it down,” she explained, noting the importance of allowing gut bacteria to adjust to increased fiber levels.

Certain individuals should be particularly cautious about their fiber intake. People with sensitivities to gluten or allergies to ingredients like soy, shellfish, or psyllium husk need to scrutinize labels, as some fiber-added products may contain these allergens.

Ultimately, Sander Kersten, director of the Division of Nutritional Sciences at Cornell University, questions the singular focus on fiber or protein. He emphasizes that “we don’t need nutrients; we need foods,” advocating for a balanced diet that includes a variety of healthy foods rather than concentrating solely on one nutrient.

As the popularity of fiber continues to grow, consumers are encouraged to prioritize whole foods while enjoying the benefits of this essential carbohydrate.
