Generally, vegetables with the lowest starch content have the lowest amounts of carbohydrates. Leafy greens such as spinach and lettuce are ideal as they contain more fiber than anything else. Other vegetables with low carbohydrate content include asparagus, mushrooms, broccoli and cauliflower. Starchy vegetables such as potatoes, corn and beets have higher amounts of carbohydrates.
