Fiber: The Overlooked Nutrient That Does So Much for Your Health
Why getting enough fiber matters—and simple ways to add more to your day
We hear a lot about protein these days.
How much do we need? Are we getting enough? Should we be eating more?
And protein certainly deserves our attention, especially as we get older.
But there's another important part of our nutrition that doesn't always get the same attention.
Fiber.
It's not particularly glamorous. It doesn't get the headlines that the latest supplement or wellness trend gets.
But fiber plays an important role in our digestive health, heart health, blood sugar regulation, and overall well-being.
And here's the good news:
You don't need an expensive supplement or a complicated eating plan to get more of it.
Let's talk about why fiber matters and some easy ways to include more of it in everyday meals.
What Exactly Is Fiber?
Fiber is the part of plant foods that our bodies cannot fully digest or absorb.
Unlike other carbohydrates, fiber passes through much of our digestive system without being broken down.
There are two main types:
Soluble fiber dissolves in water and can form a gel-like substance. It can help lower LDL cholesterol and slow the absorption of glucose, supporting healthier blood sugar levels.
Insoluble fiber adds bulk to stool and helps keep things moving through the digestive tract.
Some fibers are also fermented by beneficial bacteria in our large intestine. This process produces substances called short-chain fatty acids, which help support the health of our intestinal lining and play a role in metabolism and immune function.
Not all fibers behave exactly the same way, but together they contribute to a healthier digestive system.
Think of fiber as nourishment for both you and your gut bacteria.
And that's only the beginning.
1. Fiber Supports a Healthy Gut
We've learned a great deal in recent years about the gut microbiome—the community of microorganisms living in our digestive tract.
Some types of dietary fiber provide fuel for beneficial gut bacteria.
When these bacteria ferment fiber, they produce compounds that help support intestinal health.
Fiber also helps maintain regular bowel movements and can reduce constipation.
For women dealing with digestive changes as they get older, paying attention to fiber intake can be particularly helpful.
But there's an important distinction:
More fiber isn't always better if you increase it too quickly.
Suddenly adding large amounts can lead to gas, bloating, and discomfort.
Start gradually, drink adequate fluids, and give your digestive system time to adjust.
2. Fiber Is Good for Your Heart
Here's something many people don't realize:
Certain types of fiber can help lower cholesterol.
Soluble fiber, found in foods such as oats, beans, barley, and some fruits, can help reduce LDL cholesterol.
Higher-fiber dietary patterns are also associated with better cardiovascular health.
Some research suggests that fiber-rich diets may help support healthy blood pressure and blood lipid levels.
Of course, fiber isn't a substitute for prescribed medications or medical care.
But it's one more way our everyday food choices can support heart health.
And the beautiful thing is that we're not talking about anything exotic.
We're talking about ordinary foods you can find in almost any grocery store.
3. Fiber Helps With Blood Sugar Regulation
When we eat carbohydrate-containing foods, our bodies break down digestible carbohydrates into glucose.
Fiber—particularly soluble fiber—can slow that process.
This can help reduce how quickly blood sugar rises after a meal.
That's one reason foods like beans, lentils, and whole grains can be helpful parts of an eating pattern that supports healthy blood sugar regulation.
And here's an important reminder:
We don't have to avoid all carbohydrates to care for our metabolic health.
The type of carbohydrate, the amount, and what we eat alongside it all matter.
A bowl of beans and vegetables provides something very different nutritionally from a highly refined, low-fiber snack.
Looking at the whole food is often more useful than focusing on carbohydrates alone.
4. Fiber Can Help You Feel Satisfied
Have you ever eaten something and found yourself looking for another snack shortly afterward?
Some fiber-rich foods take longer to eat, add volume to meals, and help us feel satisfied.
That can make it easier to eat in a way that supports our needs without feeling constantly hungry.
But I want to be careful here.
Fiber isn't a trick to make you eat less.
Food is supposed to nourish us, and feeling satisfied is a good thing.
The goal isn't to suppress hunger.
It's to build meals that provide nourishment and help us feel comfortably satisfied.
5. Fiber May Support Long-Term Health
Higher fiber intake has been associated with a lower risk of several chronic diseases, including cardiovascular disease, Type 2 diabetes, and colorectal cancer.
That's significant.
And it's one more reason to look beyond short-term goals like weight management.
The foods we eat today are also part of how we care for our health in the years ahead.
There is also growing interest in how the gut microbiome may influence mood, brain function, and the gut-brain connection.
It's an exciting area of research, but we shouldn't jump to the conclusion that simply eating more fiber will treat depression or anxiety or improve productivity.
What we can say is that fiber supports important systems throughout the body, and researchers are continuing to explore those connections.
6. Fiber-Rich Foods Offer More Than Fiber
This might be one of my favorite reasons to focus on fiber-rich foods.
When we eat more vegetables, fruits, beans, lentils, nuts, seeds, and whole grains, we're not just getting fiber.
We're also getting combinations of vitamins, minerals, antioxidants, and other beneficial plant compounds.
It's a package deal!
Instead of thinking about one isolated nutrient, we're giving our bodies a variety of things they need to function well.
And that brings us back to a theme I talk about often:
What can we add to our meals that supports our health?
Not always what we need to eliminate.
Not another list of foods we're supposed to avoid.
Sometimes the most useful question is simply:
“What could I add?”
How Much Fiber Do We Need?
General recommendations for adults are approximately 14 grams of fiber for every 1,000 calories consumed.
For many women, that works out to around 25 grams per day, although individual needs vary.
Women over 50 have a recommended intake of about 21 grams per day, while some women may benefit from more depending on their overall dietary needs.
Rather than becoming obsessed with a number, I encourage you to start by looking at your usual meals.
Are you regularly including fiber-rich foods?
Could you add a serving of vegetables?
Choose whole-grain bread?
Add beans to soup?
Have berries with breakfast?
Those are the kinds of small choices that can add up over time.
Simple Ways to Get More Fiber
You don't have to overhaul your eating habits.
Here are a few easy ideas:
Add berries or chia seeds to yogurt or oatmeal.
Choose whole-grain bread more often.
Add beans or lentils to soups, salads, or casseroles.
Include a vegetable with lunch and dinner.
Snack on an apple, pear, or carrots.
Add spinach or other greens to eggs, soups, or pasta.
Try roasted chickpeas or nuts as a snack.
Leave the edible skins on fruits and vegetables when practical.
And don't overlook frozen or canned options.
Frozen vegetables, canned beans, and frozen berries can be nutritious, affordable, convenient ways to increase fiber.
Healthy eating doesn't have to mean spending hours in the kitchen.
Recipe: Easy Bean Medley
Here's a simple recipe that makes a great side dish, lunch addition, or contribution to a potluck.
It's colorful, filling, and provides fiber and plant-based protein.
Ingredients
1 (15-ounce) can kidney beans, drained and rinsed
1 (15-ounce) can pinto beans, drained and rinsed
1 (15-ounce) can black-eyed peas, drained and rinsed
1 (10-ounce) package frozen lima beans
1 cup frozen corn
1 large red bell pepper, diced
½ medium red onion, diced
½ cup fat-free Italian salad dressing
Salt to taste, if needed
Directions
Thaw the frozen lima beans and corn. You can place them in a colander and run cool water over them to help them thaw. If the lima beans require cooking according to package instructions, cook them first and allow them to cool.
Drain and rinse the canned beans.
Combine all the beans, corn, bell pepper, and red onion in a large bowl.
Add the Italian dressing and toss everything together.
Taste and adjust the seasoning as needed.
Refrigerate until ready to serve.
This salad develops more flavor as it sits and can be stored in the refrigerator for up to three days.
Nutrition Information
Approximate values provided with the original recipe, per 1-cup serving:
190 calories | 11g protein | 7g fiber | 35g carbohydrates | 1.5g fat | 450mg sodium
Actual values will vary based on ingredients, dressing, and serving size.
One cup provides approximately 7 grams of fiber—a meaningful contribution toward your daily intake.
And it's a great example of how eating well doesn't have to be complicated.
The Real Challenge Isn't Knowing Fiber Is Good for Us
Here's where I want to bring this back to everyday life.
Most of us already know that vegetables, fruits, beans, and whole grains are good for us.
The challenge often isn't a lack of information.
It's making those foods a consistent part of our lives.
Maybe you don't particularly enjoy cooking.
Maybe you're preparing meals for one.
Maybe your schedule is unpredictable.
Maybe you buy vegetables with good intentions, only to find them forgotten in the refrigerator a week later.
That's where we need to get specific.
Instead of saying:
“I need to eat more fiber.”
Ask:
“What's one fiber-rich food I enjoy, and where could I realistically add it this week?”
Maybe you add beans to your salad twice this week.
Maybe you have oatmeal for breakfast a few mornings.
Maybe you buy frozen vegetables because they're easier to keep on hand.
Maybe you make the Easy Bean Medley and enjoy it for lunch over a couple of days.
The best strategy isn't necessarily the most impressive one.
It's the one you're willing and able to repeat.
One Small Step This Week
Here's my challenge for you:
Don't try to change your entire diet.
Instead, take a look at what you're already eating and ask:
“Where could I add a little more fiber?”
Choose one meal.
Choose one food.
Make one small adjustment.
And pay attention to how it works for you.
Does it help you feel more satisfied?
Is it convenient?
Do you enjoy it?
Would you make it again?
That's how we build sustainable habits.
Not by chasing perfection, but by learning what works in our real lives.
The Bottom Line
Fiber may not be the most exciting topic in nutrition, but it deserves a place in the conversation.
It supports digestive health, heart health, blood sugar regulation, and long-term well-being.
And the best part?
Some of the simplest, most affordable foods provide it.
You don't need to do everything differently tomorrow.
Just start by adding one thing that supports your health.
Because small, consistent choices really do matter. 💚
An Apple a Day Keeps the Doctor Away?
We've all heard the saying:
“An apple a day keeps the doctor away.”
But have you ever wondered where it came from?
The saying has roots in rural Wales and was recorded as early as 1866. Back then, it sounded a little different:
“Eat an apple on going to bed, and you'll keep the doctor from earning his bread.”
I love that!
The original saying was a playful reference to avoiding doctor's bills. Apples were also a practical food in those days because they could be stored through the winter when fresh produce wasn't always available.
By the late 1800s, the saying had evolved into the shorter version we recognize today.
And while eating an apple every day certainly doesn't guarantee you won't need a doctor, there's some good nutritional wisdom behind the expression.
What's So Special About an Apple?
A medium apple with the skin provides approximately 4 grams of fiber.
That includes pectin, a type of soluble fiber that can be fermented by beneficial bacteria in our gut.
Apples also contain polyphenols—plant compounds with antioxidant properties that are being studied for their potential health benefits.
And here's something worth knowing:
A significant portion of an apple's fiber and beneficial plant compounds is found in or near the skin.
So, when practical, enjoy the whole apple!
Whether you choose organic or conventional apples, wash them thoroughly under running water before eating. Peeling is an option if you prefer it, although you'll lose some of the fiber and polyphenols.
Sometimes the Simplest Foods Are the Best Place to Start
I think there's a lesson here that goes beyond apples.
We can spend so much time looking for the newest superfood, supplement, or nutrition trend that we overlook the ordinary foods that have been nourishing people for generations.
An apple.
A bowl of oatmeal.
A handful of berries.
Some beans added to soup.
Vegetables with dinner.
Nothing fancy.
And you don't have to eat an apple every single day to benefit from fiber.
The real opportunity is to include a variety of fiber-rich plant foods consistently.
So maybe the old saying deserves a little update:
“An apple a day is one simple way to give your body something good.” 🍎
Not quite as catchy as the original, but perhaps a little more accurate!
