Fibremaxxing is America's newest diet obsession—but is it safe?

Americans are paying more attention to fibre in their diets. The push for higher intake comes as health experts highlight its benefits, from better digestion to weight management. Social media and food industry leaders are now calling it the next major trend after protein. Fibre plays a key role in keeping the gut healthy. It feeds good bacteria, helps food move smoothly through the digestive system, and can lower cholesterol. There are two main types: soluble, which dissolves in water, and insoluble, which does not.

The recommended daily amount is 14 grams for every 1,000 calories eaten. For most women, this means about 25 grams a day, while men should aim for 38 grams. A cup of raspberries provides 8 grams, and a banana offers 3.2 grams. Many people are now trying to hit these targets, a practice called *fibremaxxing*. But adding too much too fast can lead to discomfort, like gas and bloating. Experts advise increasing intake slowly and choosing whole foods—fruits, vegetables, and whole grains—rather than processed options. Some groups, such as those with gluten sensitivity or food allergies, need to be careful. A sudden jump in fibre could cause problems for them. Despite the risks, hundreds of online videos now share recipes and tips for boosting fibre intake. PepsiCo CEO Ramon Laguarta recently predicted fibre would become the next big food trend, following the popularity of high-protein diets. The market has already seen a rise in products with added fibre, though exact numbers for the US remain unclear.

The demand for fibre-rich foods is growing, driven by health claims and social media buzz. While benefits like improved digestion and weight control are well-documented, experts warn against rapid changes. Gradual increases and whole-food choices remain the safest way to meet daily needs.
