What is Fiber and Why Does It Matter?

By: Alana Hansen-Baun

You’ve probably heard it before—“Eat more fiber!”—but have you ever stopped to think about why fiber is such a big deal? It turns out this plant-powered nutrient does more for our bodies than we might realize. And here’s the kicker: most of us aren’t getting nearly enough.

Let’s dig in (pun intended) and explore what fiber does, why it’s essential, and how you can help bring more of it to the students you serve every day.

So, What Exactly is Fiber?

Fiber is a special type of carbohydrate, but unlike other carbs, our bodies can’t fully break it down. Instead of getting absorbed, fiber takes its time moving through the digestive system, doing all sorts of good along the way.

There are two main types of fiber:

• Soluble fiber: Think of it like a sponge. It soaks up water and forms a gel in the gut. This type can help manage cholesterol and steady blood sugar levels.

• Insoluble fiber: This one’s all about keeping things moving. It helps prevent constipation and supports healthy digestion.

Both types are important, and most fiber-rich foods naturally have a little of each.

Why Fiber is a Rock Star for Health

Getting enough fiber can truly make a difference. Here’s what it brings to the table:

• Happy, Healthy Tummies: Fiber keeps things moving in the digestive system, which helps prevent those uncomfortable bouts of constipation.

• Heart Power: Fiber is known to help lower cholesterol, reducing the risk of heart disease.

• Steady Energy: It slows how fast sugar enters the bloodstream, supporting more stable energy levels.

• Long-Term Protection: A high-fiber diet is linked to lower risks of conditions like Type 2 diabetes, certain cancers, and even high blood pressure.

• Feeling Full and Satisfied: Fiber can help curb overeating by making meals more satisfying.

In short? Fiber is the quiet champion helping us feel better, longer. Ready to see how much you know about fiber? Take this fun fiber quiz and test your skills!

The Fiber Gap: Why It Matters in Schools

Here’s the challenge: most people in the United States, including kids, aren’t eating enough fiber. In fact, only a small percentage of children and adults hit their daily fiber goals.
