Understanding Net Carbs

Understanding net carbs is essential for those on low-carb diets such as keto. Net carbs are total carbohydrates minus fiber, which the body cannot digest, so it doesn't raise blood sugar. By focusing on net carbs, individuals can enjoy the nutrients of vegetables without compromising their diet goals.

The Top Lowest Carb Cruciferous Vegetables

Not all cruciferous vegetables have the same carbohydrate density. Here is a look at some of the best choices for keeping carb counts low.

Radishes

Radishes are an excellent low-carb option, with most of their carbs coming from fiber. One cup of sliced raw radishes has about 3.9g of total carbs and 1.9g of fiber, which results in only 2g of net carbs. These vegetables can be eaten raw in salads, pickled, or roasted as a low-carb side dish. They also contain vitamin C and antioxidants.

Bok Choy

This Chinese cabbage has a mild flavor and is very low in carbs. One cup of raw, shredded bok choy contains approximately 1.5g of carbohydrates, with 0.7g of fiber, which equals less than 1g of net carbs. It's ideal for stir-fries and soups and can be steamed or sautéed with garlic and ginger.

Arugula

This peppery green is packed with nutrients and has a very low carb count. A two-cup serving contains just 1.5g of carbs. Arugula is great as a salad base, in sandwiches, or to make flavorful pesto. It is rich in vitamins A, C, and K, along with calcium and folate.

Cauliflower

Cauliflower has become a low-carb staple because it can replace grains and potatoes. One cup of chopped cauliflower offers around 5g of total carbs and 2g of dietary fiber, leaving just 3g of net carbs. It can be turned into rice, pizza crust, or a creamy mash, reducing the carb load of meals. It's also a good source of vitamin C and potassium.
