Savor These Fiber-Filled Vegetables

Consume a variety of vegetables to obtain different sources of fiber. Mature vegetables (those harvested at later growth stages) tend to contain more lignin; those harvested at an earlier growth stage have higher contents of pectin and hemicellulose. Eat as much as you want of these vegetables without feeling guilty: asparagus, beets, broccoli, cabbage, carrots, cauliflower, celery, chicory, chili peppers, cucumber, dandelion, endive, garden cress, garlic, green beans, lettuce, onions, radishes, spinach, and turnips.
