Why Fiber Deserves More Attention Than Protein

From protein-packed yogurts to high-protein cereals and snacks, we’re constantly told that more protein is the key to a healthier, stronger body. And while protein is undeniably essential, it might be time to turn your attention to another vital nutrient that’s quietly missing from most American diets: fiber.

Despite its low-key reputation, fiber plays a powerful role in maintaining everything from gut health to cholesterol levels. In fact, it might just be the missing link in your wellness routine.

Fiber vs. Protein: Should You Shift Your Focus?

Protein gets all the glory and for good reason. It helps build muscle, supports immune function, and keeps you feeling full. But the average American is already getting more than enough of it. According to the Dietary Guidelines for Americans, most adults, particularly men ages 19 to 59, exceed their daily protein needs, primarily through animal products like meat, poultry, and eggs.

Fiber, on the other hand, is a different story. An estimated 90% of women and 97% of men in the U.S. don’t get enough fiber, with women needing at least 25 grams per day and men 38 grams. That gap is more than a nutritional oversight it’s a health red flag.

“Fiber deserves more of the spotlight because there’s so much room for improvement with intake,” says nutrition expert Samantha Cassetty, MS, RD. “It supports gut health, digestion, blood sugar regulation, cholesterol levels, and even longevity.”

How to Know If You’re Low on Fiber

If you're not regularly eating fruits, veggies, nuts, seeds, or whole grains, chances are you’re not getting enough fiber. Signs your body might be giving you include:

• Constipation or irregular digestion

• Bloating or GI discomfort

• Blood sugar spikes or dips

• Elevated cholesterol

• Feeling hungry shortly after meals

Even without these symptoms, most Americans are still falling short, says registered dietitian Amy Shapiro, MS, RD.

Easy, High-Fiber Meal Ideas That Also Prioritize Protein

Getting 25–38 grams of fiber a day isn’t as daunting as it sounds especially when you make small, strategic changes. And you don’t have to sacrifice protein in the process. Here’s a day’s worth of RD-approved meals that combine the best of both worlds:

• Breakfast: Smoothie with Greek yogurt, frozen blueberries (4g), spinach (5g), tahini (1g), and flaxseed meal (2g)

• Lunch: Grain bowl with quinoa (5g), chickpeas (3g), roasted broccoli (4g), walnuts (1g), and grilled chicken

• Snack: Apple (4g) with almond butter (2g)

• Dinner: Grilled salmon with roasted potatoes (3g) and cauliflower (3g)

Want a quick boost? Shapiro’s go-to smoothie recipe offers about 12 grams of fiber:

• ¾ cup berries

• 1 scoop protein powder

• 1 tablespoon basil seeds

• ½ cup frozen cauliflower

• Unsweetened almond milk

For lunch or dinner, a salad loaded with greens, two cups of veggies, beans, avocado, and your choice of protein will pack at least 15 grams of fiber.

Tips to Boost Your Fiber Intake Naturally

• Add at least one plant-based ingredient to every meal

• Eat a variety of plant foods: fruits, vegetables, legumes, nuts, seeds, and whole grains

• Swap refined grains for whole grains (like whole wheat bread, brown rice, and oats)

• Check nutrition labels for products with 5g or more fiber per serving

And yes, high-fiber supplements and snacks can help fill in the gaps. Options like Olipop sodas, Bellway powders, and Smart Sweets offer convenient boosts but use them as a backup, not your primary source. “Fiber-rich whole foods offer essential nutrients and antioxidants that isolated fiber products don’t,” says Cassetty.

A Word of Caution: Go Slow

If you’re increasing your fiber intake, do so gradually to avoid digestive discomfort. And don’t forget to drink plenty of water fiber needs fluid to do its job properly.

The Bottom Line

Both protein and fiber are essential but while protein is rarely in short supply, fiber often is. By giving fiber a more central role in your meals, you can improve digestion, feel fuller longer, support heart health, and create a more balanced, nourishing plate overall.

“Fiber is only found in plant foods,” Cassetty notes, “and those same foods provide a wide array of nutrients that work together to support your health.”
