2. Lima beans: 5.3 g of soluble fiber per serving
Lima beans are large, flat, yellow-white beans. Also known as butter beans.
They contain mainly carbohydrates and protein and some fat. They have less total fiber than black beans, but their soluble fiber content is almost identical (5.3 g per three-quarter cup).
These beans also contain the soluble fiber pectin, which can reduce blood sugar spikes after meals.
It is important to soak and cook lima beans before consumption because they’re toxic in raw form.
