Are You Really Eating Enough Fiber? (Most of Us Aren't)
Quick question: how much fiber did you eat yesterday?
If you're not sure, you're in good company. National survey data show only about 5% of adults and kids reach the recommended daily fiber — yet about two-thirds of people believe they do. The Dietary Guidelines have called fiber a "nutrient of concern" since 2005.

Our house has been obsessed with gut health for years — my son has Crohn's disease — and fiber is a big part of it. The more I learned, the more obsessed I got. So let's figure out where you actually land.
How much fiber do you need?
Here are the official daily goals. Think of them as the floor, not the finish line.
| Who | Daily fiber goal |
|---|---|
| Women under 50 | 25g |
| Women 50 and older |
|
| Men under 50 | 38g |
| Men 50 and older | 30g |
| Kids 4–8 | 25g |
| Kids 9–18 | 26–38g |

A note for women over 50: the 21-gram guideline is outdated. Your body's need for fiber doesn't drop after menopause — if anything, it goes up. So skip the lower number and aim for at least 25–35 grams a day.
Where most of us actually are
The average American eats 10 to 15 grams of fiber a day — roughly half of even the most conservative goal. I call the distance between where you are and where you want to be your Fiber Gap. And here's the surprising part: you can eat "healthy" all day and still have one.
Even I, and my most health-conscious friends, have had reality checks when we tracked our fiber. Here's what you might think is a healthy day:
| What you might think is a healthy day | Fiber |
|---|---|
| Greek yogurt with ½ cup blueberries | ~2g |
| Big lunch salad (greens, cucumber, tomato) | ~4g |
| Salmon, 1 cup brown rice, 1 cup broccoli | ~8.5g |
| Total | ~14.5g |
That's a lovely day of eating — and it's still about 10 grams short. Now add ½ cup of black beans to that salad (8g) and 2 tablespoons of Löta to the yogurt (10g), and you're at about 32 grams. Small swaps, big difference.
Know your number
You can't close a gap you can't see. So here's my challenge: track your fiber for a few days and see where you land. Write down what you actually eat — not what you planned to eat. No judgment, just information.

Prefer your phone? These apps all show your daily fiber (not sponsored):
- MyMacros+ — my personal favorite. Scan barcodes, log meals, and see fiber right alongside your macros.
- Cronometer — the most accurate food data; fiber tracking is free.
- MyFitnessPal — the biggest food database, great for restaurant meals.
- Lose It! — snap or scan your food and watch your fiber add up.
My personal goal: 35 grams
I aim for 35 grams of fiber a day. Not perfectly, not every day — but that's my target. I try to get at least 25 grams from real whole foods: beans, seeds, vegetables, fruit, oats. Then I use 2 tablespoons of Löta for the other 10. Real food first, always. Löta fills in what real life can't always provide.
One important note: please don't jump from 12 grams to 35 tomorrow. Your gut bacteria are used to what you eat now, so build up gradually over a few weeks. My free Good Gut Guide walks you through exactly how to ramp up comfortably.
