If you’re new here, these three are the place to start — the foundations everything else builds on.
Organic egg fiber shown with a woven basket of fresh brown eggs nestled in straw on a rustic farm style table
No. Organic eggs fiber content is 0 grams, exactly like conventional eggs, because no egg contains fiber. The organic seal is a farming standard covering feed and outdoor access for the hens, not a nutrition upgrade, though a few feed choices do change what ends up in the yolk.
Quail egg fiber shown with a bowl of speckled quail eggs and halved boiled quail eggs on a cream colored plate
Quail eggs fiber content is 0 grams, whether you eat one or a dozen. Each 9 gram egg brings about 14 calories and 1.2 grams of protein, and by weight quail eggs carry nearly twice the riboflavin and iron of chicken eggs, along with far more cholesterol.
Chicken vs duck egg fiber shown with a large cracked duck egg shell beside smaller brown chicken eggs in cups
On chicken vs duck eggs fiber, the result is a tie at 0 grams, so neither egg is the higher fiber choice. The real differences are elsewhere: duck eggs win on B12 and iron, while chicken eggs give more protein per calorie and far less cholesterol.
Duck egg fiber shown with large pale duck eggs in a wooden bowl and a duck egg cooked sunny side up in a dish
Duck eggs fiber content is 0 grams, the same as a chicken egg. The surprise is everything else: one 70 gram duck egg carries about 158 percent of the Daily Value for vitamin B12, plus about 9 grams of protein and nearly half your selenium.
Chicken egg fiber shown with a ceramic bowl of brown and white chicken eggs and one egg cracked open in the bowl
Chicken eggs fiber content is zero in every size, grade and shell color, from a peewee to a jumbo. What the carton label does change is how much protein, choline and selenium you get, so here’s how to read it and where to find the fiber instead.
Egg white vs yolk fiber shown with a cracked egg in a bowl, a separated golden yolk in another bowl and whole eggs
On egg whites vs yolks fiber, it’s a tie: USDA lists 0 grams in both, so a whole egg has none either. What does differ is everything else, since the yolk holds 43 percent of a large egg’s protein plus nearly all its choline, vitamin D and B12.
High protein high fiber foods shown in bowls of green edamame, chickpeas, lentils and diced squash on a tray
The high protein high fiber foods that clear both FDA label bars, at least 10 grams of protein and 5.6 grams of fiber per serving, are almost all legumes: split peas, lentils, navy, pinto, black and mung beans, chickpeas and edamame. Most other protein foods clear only one.
Animal proteins and fiber shown on a plate with a grilled chicken breast, salmon, halved boiled eggs and cheese
Almost no animal protein fiber exists: meat, fish, dairy and eggs all list 0 grams in USDA data. The one true exception is insects, whose chitin counts toward fiber, so whole cricket powder carries 6.7 grams of fiber per 100 grams along with 67 grams of protein.
Meat with fiber shown in a homemade chicken pot pie with a slice cut out to reveal peas and carrots in the filling
Plain meats fiber content is 0 grams, whether it’s chicken, beef, pork, lamb or fish. The meat foods that do list fiber get it from plant ingredients, and in USDA data a frozen turkey pot pie leads with 4.4 grams per serving, while whole grain breaded nuggets bring 2 grams.
Protein powders with the most fiber shown in small bowls of pea protein, hemp protein and peanut powder with a scoop
The protein powders with most fiber are made from whole seed or legume flours: a hemp protein powder at 26 percent fiber, defatted soy flour at 17.5 grams per 100 grams and peanut flour at 15.8. Isolates of soy, pea and whey, plus egg white and gelatin, carry 0 grams.
Vegetarian proteins with fiber shown with a glass of oat milk, a bowl of yogurt with berries and scattered chickpeas
For vegetarian protein fiber, legumes lead: a cup of lentils has 15.6 grams of fiber with 17.9 grams of protein. Eggs, dairy and most dairy alternatives add little or none, and unsweetened oat milk shows 0 grams of fiber per 100 grams in USDA data.
Vegan protein with the most fiber shown in a bowl of split peas in broth, a bowl of red beans and a cup of soup
Gram for gram, navy beans are the vegan protein with most fiber, at 10.4 grams per 100 grams cooked, followed by black beans, split peas and lentils. Tofu, lupini and seitan carry far more protein per gram but only 0.5 to 2.8 grams of fiber.
