How Fiber Works
Fiber is a type of carbohydrate the body can't digest. This indigestible nature is what provides its numerous benefits. There are two main types:
- Soluble Fiber: Dissolves in water, forming a gel-like substance that can help lower cholesterol and blood sugar.
- Insoluble Fiber: Doesn't dissolve in water, adding bulk to stool and promoting regularity.
Getting Enough Fiber
Aim for at least 25-35 grams of fiber per day. Good sources include:
- Fruits (apples, berries, bananas)
- Vegetables (broccoli, spinach, carrots)
- Legumes (beans, lentils)
- Whole grains (oats, brown rice, quinoa)
Conclusion
Incorporating sufficient fiber into your diet is essential for maintaining good health. Its impact on digestion, disease prevention, and overall well-being is undeniable.
