High fiber intakes are good for health
Following a diet high in fiber is beneficial for our health. High fiber intakes have been associated with a lower risk of developing heart disease, stroke, hypertension, diabetes, obesity, and certain gastrointestinal diseases. It may lower elevated blood pressure and serum cholesterol levels, improve insulin sensitivity and enhance immune function!
We should consume at least 14 g of fiber per 1,000 calories. Hence, people who follow a typical 2,000-calorie diet should consume at least 28 g of fiber a day. More is better, though.
Getting too much fiber from food is rather unlikely. Actually, 90% of Americans fail to meet the recommended daily fiber intakes!
Keep in mind that there is no fiber in animal-based foods like meat, eggs, and dairy. Refined-products contain negligible amounts of fiber as well. Only plants are high in fiber. Therefore, only by following a whole-food, plant-based diet can significantly increase fiber consumption.
