High-fiber, low-carb food list

How can we find foods that are low in carbohydrate, yet high in fiber? Interestingly, almost all the non-starchy vegetables and low-sugar fruits are the ones that are highest in both fiber and nutrients. So if you just want a list of high-fiber vegetables and fruit, you just have to look at the lists of those which are low in carbohydrates.

If you are looking for numbers, one good guide for those limiting carbs is to look at the ratio of usable carb (or effective or net carb) compared to fiber — in other words, how much carbohydrate do I have to eat to get a gram of fiber?

Here is a list, roughly in order on this carb/fiber scale. For foods not on this list, I recommend going to Caloriecount.com, which nutritional information for most foods.

Note: I know there are discrepancies here. These data are taken from Version 18 of the USDA Database. For explaining some of the incongruities, see Understanding Carb Counts and Why Carb Counts Vary. For more detailed carbohydrate information, check out How to Count Carbs, which includes links to carb and fiber counts, glycemic index and load, and other information.



Almost All Fiber

Flax Seeds!! There is almost no usable carbohydrate in flax seeds. It is very high in both soluble and insoluble fiber (about one-third of the fiber is soluble), and has a pile of nutrients to boot. Flax is just could be the ultimate low-carb fiber source. 1 T ground flax has 2.0 grams of carbohydrate, 1.9 of which is fiber.

Help us to report stories that expose human rights violations, corruption, environmental degradation, spark reforms and generally spotlight issues of public interest.
While traditional news reporting is losing its relevance, serious investigation now requires more than basic journalistic skills. To do this we require a lot of resources.

Nelson Mandela once said: “A critical, independent, and investigative press is the lifeblood of any democracy. The press must be free from state interference. It must have the economic strength to stand up to the blandishments of government officials. It must have sufficient independence from vested interests to be bold and inquiring without fear or favor. It must enjoy the protection of the constitution, so that it can protect our rights as citizens.”

If you like our journalism support us to continue bringing you groundbreaking and agenda setting stories.
