Taken together, the above studies prompt the question: What is the prebiotic activity of SCF? If it is a true fiber, per our definitions above, then SCF should have a beneficial effect on gut microbiome bacteria. A study performed in 24 adolescents noted an increase in beneficial bacteria (e.g., Bacteroides, Butyricicoccus, Oscillibacter, and Dialister). Furthermore, this was correlated with an increase in calcium absorption upon the consumption of 12 grams of SCF per day for three weeks. An additional study, which administered 8, 14, and 21 grams of SCF over 14 days, found that good bacteria (e.g., Bifidobacteria) increased and peaked at 8 grams per day. This value is nearly identical to inulin, which is considered the “gold standard.” Despite its nearly parallel effects to inulin at 8 grams/day, research has demonstrated that SCF is 3-4 times more tolerable than inulin due to its slower rate of digestibility by the gut bacteria. In fact, 26 grams of SCF barely increased GI symptoms relative to a placebo!
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.”
Skimping on fiber isn’t good for your digestive health, as it feeds the good bacteria in your GI tract, something that benefits you beyond adequate bowel movements. “The digestive tract is where your body’s second brain is, and it’s home to the majority of your immune system,” says Elia. “If you’re following keto, it should be one of your biggest priorities to make sure you get adequate fiber to keep your gut healthy and happy,” she adds. And, she notes, high-fat diets slow digestion and decrease GI motility, so it’s especially important to get enough.
