Your Guide to Low-Carb Nut Selection
Nuts and seeds are a staple in many low-carb and ketogenic diets due to their high fat, moderate protein, and relatively low carbohydrate content. However, the net carb count—total carbs minus fiber—differs significantly between varieties. This guide will help you navigate the nutty landscape and select the best options to keep you in ketosis.
The Lowest Carb Nut Choices
When counting every carb matters, some nuts stand out for their exceptionally low net carb content. These are your top-tier choices for snacking, baking, and adding flavor to meals.
- Macadamia Nuts: Often considered the king of keto nuts, macadamias boast a high fat-to-carb ratio. They are creamy, buttery, and incredibly low in net carbs, with approximately 1.5 grams per ounce. Their high monounsaturated fat content also makes them heart-healthy.
- Pecans: These sweet, flavorful nuts are another excellent low-carb option, providing around 1.2 grams of net carbs per ounce. Pecans are rich in antioxidants and support brain health. They are perfect for both sweet and savory applications.
- Brazil Nuts: For a strong source of selenium, look no further than Brazil nuts. They offer about 1.3 grams of net carbs per ounce. Due to their high selenium content, just one or two nuts a day can meet your needs, so they should be consumed in moderation.
Moderate-Carb Nuts to Enjoy in Moderation
For those with more flexibility in their carb allowance, several other nuts can be included in a low-carb diet. Portion control is key with these choices to ensure you don't exceed your daily carb limit.
- Walnuts: Known for their rich omega-3 fatty acid content, walnuts contain approximately 2 grams of net carbs per ounce. They are great for adding texture to salads or enjoying as a standalone snack.
- Hazelnuts: With about 2.3 grams of net carbs per ounce, hazelnuts are another good option. They are a great source of vitamin E and can be used in keto-friendly desserts or crushed for a crunchy topping.
- Almonds: A versatile and popular choice, almonds have around 2.9 grams of net carbs per ounce. They are widely available and provide an excellent source of vitamin E and magnesium. Almond flour is also a great low-carb alternative for baking.
- Peanuts: Although technically a legume, peanuts are nutritionally similar to other nuts and are a low-carb favorite. An ounce contains about 3.6 grams of net carbs. Be sure to choose natural, unsweetened peanut butter to avoid hidden sugars.
High-Carb Nuts to Limit or Avoid
For stricter low-carb diets, such as the ketogenic diet, some nuts should be limited or avoided entirely due to their higher carbohydrate count. The carbs can add up quickly with these options.
- Cashews: While delicious, cashews contain significantly more net carbs than other popular nuts, with around 8.4 grams per ounce. It's best to enjoy them only in small amounts or save them for a special occasion on a low-carb diet.
- Pistachios: Pistachios are another nut with a higher carb count, coming in at around 4.9 grams of net carbs per ounce. While not as high as cashews, their carbs can accumulate quickly, so they should be consumed sparingly.
- Chestnuts: These are the highest-carb nuts, with around 13.6 grams of net carbs per ounce. Chestnuts are not suitable for low-carb or keto diets.
