There is no argument that fiber is beneficial for a diabetic. The problem is that many foods that are high in fiber are also high in carbohydrates. Prime examples are whole grains and legumes. Which are great for high-carb low-fat vegans. However, low-carb high-fat diabetics need to get fiber from low-carb sources, such as chia seeds, flaxseed, psyllium husks, and non-starchy fibrous vegetables.
