In a world obsessed with protein powders, keto diets, and superfoods, one humble nutrient continues to reign supreme fiber. Often overlooked, fiber is a powerhouse that supports digestion, heart health, weight management, and even mental well-being. As we step into 2025, the importance of fiber in our diets has never been clearer.
This guide will walk you through everything you need to know about fiber what it is, why it matters, how to get more of it, and how it can transform your health without breaking your budget.
What Is Fiber?
Dietary fiber is a type of carbohydrate found in plant-based foods that your body can’t digest. Unlike other carbs, fiber passes through your digestive system relatively intact, doing important work along the way.
There are two main types:
- Soluble fiber: Dissolves in water to form a gel-like substance. It helps lower cholesterol and regulate blood sugar.
- Insoluble fiber: Adds bulk to stool and helps food pass more quickly through the stomach and intestines.

Key Benefits:
