The Daily Value for dietary fiber in the United States is 28 grams a day, and most people get nowhere near it. That number is not arbitrary: it comes from a recommendation of 14 grams of fiber per 1,000 calories eaten, applied to a 2,000 calorie reference diet, which means your own target rises and falls with how much you eat.
The gap between that target and real life got a fresh measurement this month. On September 15, 2026, The New York Times published an interactive guide by Alice Callahan on how much fiber you need, reporting that the average American woman eats about 15 grams a day and the average man about 18, against a recommended minimum of 21 to 38 grams depending on age and sex. Two days earlier, a peer reviewed analysis of fifteen years of national survey data put a sharper number on the same problem. Both are below.
The official number, and why it moves
The 28 gram Daily Value is the figure used on every Nutrition Facts label in the country, published by the FDA. It is a single reference number designed for label math, not a personal prescription.
The recommendation underneath it is expressed as a density: 14 grams of fiber per 1,000 calories. At 2,000 calories a day that works out to 28 grams, which is exactly where the label figure comes from. The practical consequence is that a smaller person eating 1,600 calories has a target closer to 22 grams, and a larger or very active person eating 2,700 calories has a target closer to 38. That is the same range the Times reports.
| Figure | Amount | What it is |
|---|---|---|
| Daily Value on the label | 28 g | FDA reference figure used to calculate %DV |
| Underlying recommendation | 14 g per 1,000 calories | Scales with how much you eat |
| Typical adult range | 21 to 38 g | Varies by age and sex |
| Actual US average, women | about 15 g | Reported by The New York Times, September 2026 |
| Actual US average, men | about 18 g | Reported by The New York Times, September 2026 |
How big is the gap, measured properly
Grams per day is the familiar way to state the shortfall, but it is a blunt instrument, because someone eating 1,400 calories and someone eating 3,000 are being compared against the same bar. Density is the better measure, and a study published in Clinical Gastroenterology and Hepatology on September 7, 2026 by Kira Newman and colleagues at the University of Michigan reports it directly.
Analysing seven cycles of the National Health and Nutrition Examination Survey covering 2009 through 2023, the researchers found that mean and median fiber intake was below the recommended 14 grams per 1,000 calories in every group they examined. Adults were at 8.26 grams per 1,000 calories in the most recent cycle. People under 20 were at 7.97.
| Group | 2009 to 2010 | 2021 to 2023 | Recommended |
|---|---|---|---|
| Under 20 years | 7.37 g per 1,000 cal | 7.97 g per 1,000 cal | 14 g per 1,000 cal |
| 20 years and over | 8.52 g per 1,000 cal | 8.26 g per 1,000 cal | 14 g per 1,000 cal |
Read plainly, Americans are eating a little over half the fiber density recommended, and the figure has barely moved in fifteen years. After adjusting for age, sex, race and ethnicity, and household income, the authors found a small but statistically significant decline of 0.05 grams per 1,000 calories per year.
Where fiber actually comes from
Fiber exists only in plants. There is no fiber in meat, fish, eggs, dairy or oil, which is why a meal built on those alone contributes nothing toward the day's total no matter how large it is.
Beans, lentils and other legumes are the densest common sources, at roughly three to five grams per half cup as the Times reports. Whole grains, nuts, seeds, fruit with the skin on and vegetables fill in the rest. Below are USDA values for several common vegetables, given per 100 grams so that they can be compared on one basis.
| Vegetable, as prepared | Fiber per 100 g | USDA FoodData Central ID |
|---|---|---|
| Kale, cooked, boiled, drained | 4.0 g | 169238 |
| Broccoli, cooked, boiled, drained | 3.3 g | 169967 |
| Carrots, raw (about 1.6 medium carrots at 61 g each) | 2.8 g | 170393 |
| Brussels sprouts, cooked, boiled, drained | 2.6 g | 169971 |
| Spinach, cooked, boiled, drained | 2.4 g | 168463 |
The honest reading of that table is that vegetables are not the most concentrated fiber source available. A cup of beans will beat a cup of spinach every time. What vegetables do is make the total reachable without every meal turning into a bowl of legumes, and they carry vitamins, minerals and plant compounds that a fiber count does not capture. If you want to widen the range of plants you eat rather than just the gram total, see how many different plants you should eat in a week.
What the words on the package legally mean
Fiber is one of the nutrients the FDA allows to be advertised on the front of a package, and the thresholds are fixed in regulation rather than left to the manufacturer. Knowing them turns a marketing phrase into a number.
| Phrase on the package | What it requires | In grams of fiber |
|---|---|---|
| "Good source of fiber", "contains fiber", "provides fiber" | 10 to 19 percent of the Daily Value per serving | 2.8 g to 5.3 g |
| "High in fiber", "rich in fiber", "excellent source of fiber" | 20 percent or more of the Daily Value per serving | 5.6 g or more |
| FDA's general rule of thumb | 5 percent DV or less is low, 20 percent DV or more is high | 1.4 g or less is low |
The thresholds sit in 21 CFR 101.54. FDA also names dietary fiber on its own Daily Value page as one of the nutrients to choose more of, alongside vitamin D, calcium, iron and potassium.
Do fiber supplements count?
They count toward the number, and for some people they are a reasonable addition. The Times piece deliberately builds its day without them, on the reasoning that most supplements contain only one or two types of fiber while fiber-rich foods contain many, and that variety is part of what feeds a diverse gut microbiome.
There is a regulatory wrinkle worth knowing. Fiber that is intrinsic and intact in plants counts as dietary fiber automatically. Fiber that has been isolated or synthesised counts only if the FDA has specifically determined it has a beneficial physiological effect, and the agency has approved a closed list of seven: beta-glucan soluble fiber, psyllium husk, cellulose, guar gum, pectin, locust bean gum and hydroxypropylmethylcellulose. Anything outside that list can be in a product without counting as fiber on the label.
For a direct comparison of whole vegetables against isolated fiber, see SaladPower vs. fiber powders. For the question of which type of fiber to look for, see soluble vs. insoluble fiber.
Building a realistic 28 grams
The arithmetic is less daunting than it sounds once each item is priced in grams. A day that clears the Daily Value might look like this.
| Meal | Rough fiber | Running total |
|---|---|---|
| Oats with berries and a spoon of seeds | 8 g | 8 g |
| Lunch with a half cup of beans or lentils added | 7 g | 15 g |
| An apple or a pear, skin on | 4 g | 19 g |
| Dinner with two servings of vegetables | 6 g | 25 g |
| A vegetable drink or a handful of nuts | 5 g | 30 g |
Two observations from the table. The first is that no single item does the work; the day is won in five-gram increments. The second is that fiber intake should be increased gradually and with enough fluid, because a sudden jump commonly causes gas and bloating.
Where SaladPower fits
One 8 oz pouch of SaladPower contains 5 grams of fiber, which is 18 percent of the Daily Value. That clears the FDA's 10 percent threshold, so fiber is one of the nutrients the product can be called a good source of.
Put in the terms of this page, a pouch covers a little under a fifth of a 28 gram day. It is six whole organic ingredients, spinach, kale, carrot, broccoli, apple and lemon, blended and nothing else, delivering 2x the USDA daily recommended vegetable intake in a pack that is commercially processed, sealed and shelf-stable. It is a way to make the vegetable portion of the day happen on days when cooking does not. The other 23 grams still come from beans, grains, fruit and the rest of the plants you eat, which is the point of the pattern rather than a shortcoming of any one product.

Frequently asked questions
How much fiber do I need a day?
The Daily Value used on US nutrition labels is 28 grams a day. The underlying recommendation is 14 grams per 1,000 calories eaten, so a person eating 1,600 calories has a target nearer 22 grams and a person eating 2,700 calories has a target nearer 38.
Is most of the country really falling short?
Yes. A September 2026 analysis of National Health and Nutrition Examination Survey data from 2009 through 2023 found mean and median fiber intake below the recommended 14 grams per 1,000 calories in every group examined, with adults at 8.26 grams per 1,000 calories in the most recent cycle. The New York Times reports daily averages of about 15 grams for women and 18 for men.
What does "good source of fiber" legally mean?
Under 21 CFR 101.54, "good source", "contains" and "provides" require 10 to 19 percent of the Daily Value per serving, which is 2.8 to 5.3 grams of fiber. "High", "rich in" and "excellent source" require 20 percent or more, which is 5.6 grams or more.
Do fiber supplements count toward the total?
They count toward the gram total. Nutrition experts generally prefer food first because a supplement typically contains one or two types of fiber while whole plant foods contain many. Isolated or synthetic fiber only counts as dietary fiber on a label if the FDA has approved it, and the approved list currently has seven entries.
How fast should I increase my fiber?
Gradually, and with enough fluid. A large sudden increase commonly causes gas, bloating and discomfort. Adding a few grams at a time over a couple of weeks is easier to sustain.
