There’s more than one type of carb—and how our bodies handle them differs. (Just when you thought nutrition was straightforward…)Here’s a quickCarb 101. There are two main types of carbohydrates: simple and complex.Simple carbsare found in fruit, milk and milk products, as well as the foods you’re typically told to limit—desserts, soda, fruit juice, candy and—well—all sugar. Your body digests them easily (i.e., they get into your bloodstream fast and raise your blood sugar quickly).Complex carbsare whole grains, beans, legumes, rice, pasta and starchy vegetables—they’re the ones that your body has to put a little more effort into digesting. And when it comes to how your body uses carbohydrates, it gets a little trickier. There’s something called net carbs. Here we break down what those are and how to calculate the net carb values of foods, plus help you figure out if you need to be looking at net carbs in the first place.Pictured recipe:Air-Fryer Sweet Potato FriesWhat Are Net Carbs?Net carbs are considered the carbohydrates that your body actually digests, though there is no formal (or government-regulated) definition. Typically, net carbs are the total carbohydrates in a food minus fiber and minus sugar alcohols. But some definitions suggest that you subtract 100% of the fiber (because it just passes through your body) and only half of the sugar alcohols because they’re partially digestible.How to Calculate Net CarbsHere’s the equation:Total Carbohydrates – Fiber – Sugar Alcohols = Net CarbsLet’s take a large banana, for example: 31 grams total carbs – 3.5 grams fiber = 27.5 grams net carbs.Here’s the net carb value for a few other common fruits and vegetables:Sweet Potato(1 large): 39g net carbsWatermelon(1 cup): 11g net carbsStrawberries(1 cup whole): 8g net carbsSpaghetti Squash(1 cup): 8g net carbsAvocado(1 whole fruit): 4g net carbsBroccoli(1 cup florets): 4g net carbsZucchini(1 cup): 3g net carbsCauliflower(1 cup florets): 3g net carbsWho Counts Net Carbs?“Mostly people subtract fiber and sugar alcohols from total carbohydrate to estimate the amount of carbohydrate that affects blood sugar,” explains Jill Weisenberger, M.S., RDN, CDE, CHWC, FAND, the Virginia-based author ofPrediabetes: A Complete Guide. But the people who track their blood sugar regularly—folks with diabetes—don’t necessarily calculate net carbs. “According to theAmerican Diabetes Association, it is not necessary to subtract dietary fiber or sugar alcohols from total carbohydrates when carbohydrate counting,” says Weisenberger. “Most diabetes educators work one-on-one with people taking insulin to determine the need to subtract fiber and sugar alcohols to maintain target blood glucose levels.“So, who is actually counting net carbs? The low-carb dieters—Atkins, keto, etc. Since theketo diet is so low in carbohydrates, counting net carbs gives you more wiggle room in your day. That can be important, especially to allow for healthy foods like vegetables in your diet.Should You Be Counting Net Carbs?One “side effect” of counting net carbs—at least for some folks—is a greater awareness of how much fiber they’re eating, and a drive to up their fiber count. In this instance, we’re all for counting net carbs because most of us don’t get enough fiber in our diets and there are someserious perks (besides just being regular!) to eating more fiber.Beyond that, it’s hard to see what, if any benefits, exist behind counting net carbs. Especially when you consider that most health organizations and health professionals don’t recognize—or recommend—counting net carbs.While that may be disappointing to hear if you’re on a low-carb diet, there really isn’t a need to count net carbs. If you are counting them, it may be a way to include more complex carbs in your diet—but otherwise we just recommend you choose more of those healthy foods to begin with.Was this page helpful?Thanks for your feedback!Tell us why!OtherSubmit

What Are Net Carbs?
Net carbs are considered the carbohydrates that your body actually digests, though there is no formal (or government-regulated) definition. Typically, net carbs are the total carbohydrates in a food minus fiber and minus sugar alcohols. But some definitions suggest that you subtract 100% of the fiber (because it just passes through your body) and only half of the sugar alcohols because they’re partially digestible.
How to Calculate Net Carbs
Here’s the equation:Total Carbohydrates – Fiber – Sugar Alcohols = Net Carbs
Let’s take a large banana, for example: 31 grams total carbs – 3.5 grams fiber = 27.5 grams net carbs.
Here’s the net carb value for a few other common fruits and vegetables:
