Complete Guide to Buying Nuts on Keto

Nuts are a popular snack choice on the ketogenic diet due to their satisfying crunch and nutrient-dense profile. However, not all nuts are created equal when it comes to their compatibility with a keto lifestyle. In this comprehensive guide, we will explore various types of nuts, and their nutritional properties, and provide you with the information you need to make informed choices when buying nuts for your keto pantry. From the best options to the ones you should avoid, let’s delve into the world of nuts and uncover the key considerations for a successful keto nut selection.

The Keto Nut Showdown: Unveiling the Best to Worst

1. Macadamia Nut: The Keto Champion

Macadamia nuts take the crown as the best choice for keto enthusiasts. They are extremely low in Omega-6 fatty acids, which can be pro-inflammatory when consumed in excess. Moreover, macadamia nuts have a remarkably low phytic acid content, a compound that can inhibit mineral absorption in the body. This combination of low Omega-6 and phytic acid content makes macadamia nuts an ideal keto nut option.

2. Pecans: A Close Runner-Up

Pecans rank as the second-best keto nut option. They are low in carbohydrates and boast a favorable Omega-6 to Omega-3 fatty acid ratio. Additionally, pecans have a low phytic acid content, which further enhances their nutritional profile. However, it’s worth noting that pecans are not as high in monounsaturated fats compared to some other nuts.

3. Almonds: Proceed with Caution

Almonds are a popular nut choice, but they come with some considerations for keto dieters. While they are relatively low in carbohydrates, almonds have a high phytic acid content. Phytic acid can hinder mineral absorption and may be problematic for some individuals. Opting for dry roasted almonds over raw almonds can help reduce the phytic acid levels, making them a better choice. However, almonds have an unfavorable Omega-6 to Omega-3 ratio, so moderation is key when including them in your keto diet.

4. Brazil Nuts: Nutrient Powerhouse with a Caveat

Brazil nuts stand out for their high selenium and choline content, which are beneficial for overall health. They also have an excellent fatty acid profile. However, it’s important to note that Brazil nuts are relatively high in phytic acid, which can counteract some of their nutritional benefits. Enjoy them in moderation to reap their unique advantages.

5. Walnuts: Omega-3 Powerhouses

Walnuts are a great source of omega-3 fatty acids, making them an excellent choice for keto dieters. They are low in carbohydrates and provide a satisfying crunch. Incorporating walnuts into your diet can contribute to a healthy fat profile while keeping your carb intake in check.

6. Hazelnuts: Fiber-Rich Digestive Allies

Hazelnuts are a good option for keto dieters due to their soluble fiber content, which promotes a healthy digestive system. They have a relatively low net carb count and can be enjoyed in moderation. However, hazelnuts also have a high phytic acid content, so be mindful of your overall intake.

7. Pistachios: Protein-Rich and Flavorful

Pistachios offer the highest protein content among nuts, making them a satisfying snack option. However, they are the highest in carbohydrates and lowest in fiber. While they have a good amino acid profile, it’s essential to consume pistachios in moderation to stay within your keto goals.

8. Cashews: A Keto No-Go

Unfortunately, cashews are not an ideal choice for a keto diet. They are relatively high in carbohydrates and have a significant phytic acid content, with over 600mg of phytic acid per 200-calorie serving. Additionally, cashews have a lower monounsaturated fat content compared to other nuts. It’s best to avoid cashews when following a ketogenic lifestyle.

What to Avoid:

1. Phytic Acid

Phytic acid is an anti-nutrient found in some nuts that can bind to minerals like zinc, iron, and calcium, reducing their bioavailability. High levels of phytic acid can interfere with nutrient absorption and may lead to mineral deficiencies over time. Nuts with excessive phytic acid content, such as cashews and hazelnuts, should be consumed in moderation or properly prepared through soaking or roasting to reduce phytic acid levels.

2. Inflammatory Seed Oils

When nuts are roasted, some manufacturers use inflammatory seed oils like soybean, canola, peanut, corn, or sunflower oil. These oils are high in omega-6 fatty acids, which, when consumed in excess, can promote inflammation in the body. To avoid these inflammatory oils, choose nuts that are either dry roasted, or roasted in healthier alternatives like coconut oil, extra virgin olive oil, avocado oil, or macadamia nut oil.

3. Yeast Extract and MSG

Some commercially packaged nuts may contain yeast extract, a flavor enhancer that often includes hidden sources of monosodium glutamate (MSG). MSG is known to trigger sensitivities and reactions in certain individuals. To ensure you’re not consuming hidden MSG, read the ingredient labels carefully and opt for plain, unflavored nuts or those seasoned with just salt, or natural herbs and spices.

4. Sweetened Nuts

Sweetened nuts, such as those coated in sugar, honey, or other sweeteners, should be avoided on a keto diet. These additions significantly increase the carbohydrate content of the nuts, undermining their compatibility with a low-carb eating plan. Choose unsweetened nuts to keep your carb intake in check.

What to Look for:

1. Monounsaturated Fat Content

Monounsaturated fats are considered heart-healthy fats that support a ketogenic lifestyle. Look for nuts that have a higher monounsaturated fat content, as they can help promote satiety and provide a good source of energy. Macadamia nuts, pecans, and hazelnuts are excellent choices due to their relatively high monounsaturated fat profiles.

2. Omega-3 Fatty Acids

Omega-3 fatty acids are essential fats that have numerous health benefits, including reducing inflammation and supporting brain health. Nuts such as walnuts and macadamia nuts are rich sources of omega-3 fatty acids and can be valuable additions to your keto diet.

3. Net Carb Count

Pay attention to the net carb count of nuts, which is calculated by subtracting the fiber content from the total carbohydrates. Opt for nuts that are lower in net carbs to help maintain ketosis and support your low-carb goals. Pecans, macadamia nuts, and walnuts are good options with relatively low net carb counts

Nuts ranked from lowest to highest net carb count per serving:

  1. Macadamia Nuts: 1 gram of net carbs per serving.
  2. Pecans: 1-2 grams of net carbs per serving.
  3. Brazil Nuts: 1-3 grams of net carbs per serving.
  4. Walnuts: 1-4 grams of net carbs per serving.
  5. Hazelnuts: 2-4 grams of net carbs per serving.
  6. Almonds: 2-4 grams of net carbs per serving.
  7. Pistachios: 5-8 grams of net carbs per serving.
  8. Cashews: 7-9 grams of net carbs per serving.

4. Phytic Acid Moderation

While some nuts may contain phytic acid, you can still enjoy them in moderation. Soaking or roasting nuts can help reduce phytic acid levels, making them more digestible and minimizing potential mineral absorption issues. Additionally, pairing nuts with other foods rich in minerals can help offset the effects of phytic acid.


In conclusion, armed with this complete guide to buying nuts on keto, you can confidently navigate the nut aisle and make informed choices that align with your low-carb lifestyle. Remember to prioritize nuts with low net carb counts such as macadamia nuts and pecans, which are excellent keto options due to their favorable fat profiles and minimal impact on blood sugar levels. Be mindful of factors to avoid, such as high phytic acid content, inflammatory seed oils, and sweetened varieties that can derail your keto progress. Instead, opt for nuts with higher monounsaturated fat content, and moderate omega-3 fatty acids, and consider soaking or roasting to reduce phytic acid levels. With this knowledge, you can now enjoy the nutritional benefits, crunch, and flavor of nuts while staying on track with your keto journey. So go ahead, snack smart, and embrace the nutty goodness that supports your health and well-being on the ketogenic diet.
