I'm actually in search of fat, from veggies like avocados or nuts. The good fats. (If Jicama had fats I would probably consider that a plus!) I'd just as soon avoid starchy veggies if they don't have much to offer. I do believe I should add more orange starches like sweet potato and squash and pumpkin to my diet somehow because of their micronutrients. I'm not lacking for fiber.
