Brazilian research highlights fiber‑rich foods and native fruits for gut health

Dietary fiber, found in foods such as oats, papaya, beans, green banana and flaxseed, supports intestinal function, promotes satiety and helps maintain a balanced diet. Adults are advised to consume 25–38 g of fiber daily, spreading intake across meals and staying hydrated for optimal effect.

A scientific review of 19 Brazilian native fruits, conducted by researchers from the University of São Paulo and the Autonomous University of Chile, identified strong antioxidant and anti‑inflammatory properties. Fruits such as jabuticaba, guaraná, cambuci, açaí, pitanga and others contain phenolic compounds that foster beneficial gut bacteria (e.g., Bifidobacterium, Lactobacillus) and may protect cardiovascular health.

Both pieces emphasize the role of fiber and bioactive compounds in supporting gut microbiota and reducing inflammation, underscoring the nutritional potential of Brazil’s biodiversity.
