High-Fiber Foods: Why They Matter & How to Add Them to Your Diet
What Is Fiber?
Fiber is a type of carbohydrate found in plant foods that your body cannot fully digest.
Instead of being broken down like sugar or starch, fiber:
✔ Helps food move through your digestive system
✔ Supports gut health
✔ Helps manage blood sugar and cholesterol
✔ Promotes fullness and weight management
Some fibers also feed beneficial gut bacteria, supporting digestive and immune health.
Remember: always consult with your healthcare provider first before making any significant dietary modifications.
Why Fiber Is Especially Important for Adults 65+
As we age, digestion often slows and certain health risks increase. Getting enough fiber can help:
✔ Prevent constipation
✔ Support heart health
✔ Improve blood sugar control
✔ Reduce cholesterol levels
✔ Support a healthy gut microbiome
✔ Help maintain a healthy weight
Certain fibers (like pectin found in fruits) may even help lower LDL (“bad”) cholesterol by reducing absorption in the digestive tract.
Types of Fiber
1. Soluble Fiber
Dissolves in water and forms a gel-like substance.
Helps:
- Lower cholesterol
- Control blood sugar
- Support heart health
2. Insoluble Fiber
Adds bulk to stool and helps food move through the digestive tract.
Helps:
- Prevent constipation
- Support regular bowel movements
3. Prebiotic Fiber
Feeds healthy gut bacteria and supports digestive balance.
Found in foods like:
- Garlic
- Onions
- Leeks
- Asparagus
