Fiber-rich foods are among the best choices in the universe. Fiber-rich fruits and vegetables, in particular, offer numerous benefits. Insoluble fibers clean the intestinal walls, while soluble fibers form a gel with water, absorbing glucose and cholesterol and reducing their absorption. They also contain minimal fat and glucose.
The presence of fiber in the intestine reduces absorption, retains water (preventing diarrhoea and constipation), cleans ulcers and gastritis areas, reduces bloating, acidity problems, and heartburn, and may even help prevent cancer and ulcers.
Fiber reduces appetite and creates a feeling of fullness (satiety), which, in turn, aids in reducing fat and carbohydrates in your daily diet.
In short, they are the best choice for intestinal health.
