Vegetables are a great source of fiber, most of them have a mix of both insoluble and soluble fiber.
Both types of fiber contribute to good health.
Here’s a table from a review study that breaks down how much fiber is in 100 grams of a variety of vegetables:
Overall, bitter gourd and beetroot had the most fiber by a substantial amount.
But as you can see, pretty much all vegetables have at least a few grams of fiber per 100 grams (which is typically much less than a serving size).
For reference, the daily recommended intake is a minimum of 25 grams for women, and 38 grams for men. There’s not really a such thing as too much fiber, even on a vegan diet.
As far as the difference between soluble and insoluble fiber:
- Soluble fiber – This is what most fiber supplements are composed of. Soluble fiber is absorbed by water in your body and adds “bulk” to your stool.
- Insoluble fiber – Passes through us whole, which can help with regularity.
It’s good to get both in your diet, and just about all foods with high amounts of fiber have more insoluble fiber than soluble fiber, as all vegetables do in that table above.
