In most cases, if you grab a low-carb snack at random from the grocery store shelf and look at the label, a common nutrient profile contains around 20 grams of carbohydrates, yet maybe 15 of those grams are from “fiber.” The result is five grams of net carbs, right? Not so fast. . . if a Type I diabetic were to consume that bar, cookie, or brownie with the five grams of net carbs, there should not be a need for insulin since, theoretically, there is minimal glucose (blood sugar) entering the system from those five net carbs, which shouldn’t require an insulin response. Unfortunately, theory and outcome do not always match.
Low in carbs and high in fiber, lupini beans (aka lupin beans) are perfect for those on keto who are looking for a high-protein, high-fiber snack. Never heard of them? This yellow legume is hot on the heels of the edamame and fava bean as an on-trend nibble for the health-conscious consumer. One cup of cooked lupini beans contains 4.6 grams of fiber—about 19% of the recommended daily value. However, ready-to-eat branded lupini bean snacks often contain even more. “I've noticed that the amount of carbs/fiber can vary greatly between lupini bean brands,” says Yule. “To make sure that you are choosing a food that is keto-friendly, be sure to check the label.”
