Understanding Fiber and Its Benefits
What is Fiber?
Fiber is a type of carbohydrate found in plant-based foods that the body cannot digest or absorb. Instead, it passes relatively intact through the digestive system, providing various health benefits.
Benefits of High-Fiber Foods for Weight Loss
- Increased Satiety: Fiber-rich foods help you feel full and satisfied, reducing overall calorie intake.
- Improved Digestive Health: Fiber promotes regular bowel movements and prevents constipation.
- Stabilized Blood Sugar Levels: Soluble fiber slows the absorption of sugar, which can help manage diabetes and prevent energy crashes.
- Lowered Cholesterol Levels: Some types of fiber, like soluble fiber, can help reduce LDL (“bad”) cholesterol levels.
- Support for Healthy Gut Bacteria: Fiber acts as a prebiotic, feeding beneficial bacteria in the gut.
Types of Fiber
1. Soluble Fiber
- Sources: Oats, barley, beans, lentils, apples, citrus fruits, psyllium husk.
- Benefits: Dissolves in water to form a gel-like substance, which helps slow down digestion and absorption of nutrients.
2. Insoluble Fiber
- Sources: Whole grains, nuts, seeds, vegetables like broccoli and carrots.
- Benefits: Adds bulk to stool and helps food pass more quickly through the digestive tract, promoting regularity.
3. Resistant Starch
- Sources: Green bananas, legumes, cooked and cooled potatoes, whole grains.
- Benefits: Resists digestion in the small intestine, acting similar to fiber in promoting fullness and supporting gut health.
