Are Cashews Keto-Friendly?

Cashews on a kitchen counter

If you're wondering whether cashews are keto-friendly, the short answer is no, primarily due to their high carb content.

This might come as a surprise, especially since cashews are often considered a healthy snack.

But when it comes to the ketogenic diet, the rules are different, and the carb content of foods becomes a crucial factor.

In this article, we delve into the carb breakdown of cashews, explain why they aren't the best fit for a keto diet, and offer some excellent alternatives to ensure you can stay in ketosis while still enjoying crunchy, satisfying snacks.

We'll also touch upon the nutritional benefits of cashews, and why they might still fit into a more relaxed low carb diet.

So, let's get started and explore the world of cashews in the context of a ketogenic lifestyle.


  • Cashews are not keto-friendly due to their high carbohydrate content.
  • Despite their nutritional benefits, cashews can make it difficult to stay within the carb limits of a keto diet.
  • Cashews can potentially disrupt ketosis, making it hard to achieve and maintain the metabolic state.

Are Cashews Keto-Friendly?

Cashews, while rich in several essential nutrients, do not typically fit comfortably into a ketogenic diet's guidelines. With a carbohydrate content of 32.19g per 100g, they exceed the usual carb limits set by most keto standards.

The reason cashews aren't considered keto-friendly is largely due to their relatively high carbohydrate content. When following a keto diet, the carbohydrate intake is drastically reduced, generally to below 50g per day, and in some stringent cases, below 20g. This low-carb approach makes it challenging to fit cashews into the diet without exceeding the daily carb allotment.

Can You Have Cashews On a Strict Keto Diet?

Incorporating cashews into a strict keto diet, which typically requires consuming less than 20g of carbs per day, can be a challenging task. Given that a typical 30g serving of cashews contains 9.66g of net carbs, it's evident that cashews can quickly use up the majority of the daily carb allowance on a strict keto diet, leaving little room for other food items.

On a slightly more relaxed low carb diet, where the daily carb intake is limited to 30-50g of net carbs, there might be a bit more flexibility. However, even under these circumstances, consuming cashews would require mindful planning as they can still contribute significantly to the daily carb limit.

Carbs In Cashews

The carbohydrate content in cashews is quite significant. For every 100g of cashews, there is a total of 32.19g of carbohydrates. Breaking this down to a typical serving size of about 30g, the net carb content comes to around 9.66g. This indicates that even small servings of cashews can contribute a substantial portion towards the daily carb limit, especially when following a low-carb or ketogenic diet.

In addition to the net carb content, it's also essential to consider the glycemic index (GI) of food items, especially for those monitoring their blood sugar levels. The glycemic index is a measure of how fast a food can increase your blood sugar levels, with lower values indicating slower digestion and absorption of carbohydrates, leading to a slower rise in blood sugar and insulin levels.

Cashews Nutrition Facts

Cashews, aside from their well-known delicious taste, are packed with a range of nutrients. A 100g portion provides 32.19g of net carbs and a slightly higher total carbohydrate count of 36.29g. This small nut also offers a good amount of dietary fiber at 4.1g.

What does stand out is the high total fats content, ringing in at 38.86g. However, these fats are primarily unsaturated, which are beneficial for heart health. Alongside these, cashews are notable for their protein content, contributing to 17.44g per 100g serving.

Moreover, cashews are not only about macro-nutrients. They're also an excellent source of essential minerals. The sodium content is quite low at 4.76mg, making them a good snack choice for those watching their sodium intake. Meanwhile, they're rich in potassium at 638.3mg and magnesium at 250.6mg, both of which are crucial for maintaining healthy physiological functions.

Cashews also contain essential trace minerals like calcium (41.95mg), copper (2.22mg), iron (5.99mg), zinc (5.07mg), and manganese (1.95mg). Of particular interest is their high phosphorus content (532.2mg), which plays a vital role in bone health. Additionally, cashews are a source of selenium, a powerful antioxidant, with a content of 20.67ug.

Cashews contain a small nitrogen component, amounting to 3.29g. Nitrogen is an essential part of amino acids, the building blocks of protein. Finally, despite being a dry nut, cashews do contain a small amount of water, around 4.81g per 100g serving.

Health Implications of Cashews on a Keto Diet

While cashews are packed with beneficial nutrients, their high carbohydrate content makes maintaining a state of ketosis a challenge. This is a crucial factor for those following a ketogenic diet, as ketosis is the metabolic state that allows the body to burn fat for energy instead of carbs.

Looking at the nutritional profile of cashews, they are a good source of several vitamins and minerals. They contain significant amounts of magnesium and phosphorus, which play vital roles in maintaining bone health, and are rich in copper, a mineral essential for energy production and antioxidant defense. Cashews also provide decent amounts of heart-healthy monounsaturated fats.

Keto-Compatible Alternatives for Cashews

  1. Almonds: Almonds are one of the most keto-friendly nuts. They have a lower carb content compared to cashews, with approximately 6g of net carbs per 30g serving. They can be used in a variety of keto recipes from almond flour-based baked goods to keto-friendly granola.
  2. Macadamia Nuts: Another excellent keto-friendly alternative to cashews, macadamia nuts, contain about 2g of net carbs per 30g serving. Their high fat and low carb content make them ideal for maintaining ketosis. You can use them in low-carb baking, salads, or simply as a satisfying snack.
  3. Pecans: Pecans are highly recommended on a ketogenic diet due to their low net carb content, which is around 1g per 30g serving. They're also a good source of monounsaturated fats and can be used in low-carb dessert recipes or as a crunchy topping for salads.
  4. Walnuts: With only around 2g of net carbs per 30g serving, walnuts are a viable alternative to cashews on a keto diet. They can be used in a wide range of dishes, including keto-friendly desserts, salads, and savory dishes, thanks to their mild, earthy flavor.

Concluding Thoughts on Cashews and Keto

In summarizing our discussion on cashews and the ketogenic diet, it's clear that while cashews are a nutritious snack loaded with essential vitamins and minerals, their high carbohydrate content makes them less suitable for a strict keto diet. A small 30g serving of cashews has around 9.66g of net carbs, which can take up a significant portion of the daily carb allowance on a ketogenic diet.

Despite their nutrient richness, the high amount of carbs makes it challenging to include cashews in a keto diet without exceeding the daily carb limit. However, their low glycemic index suggests that they might not cause rapid spikes in blood sugar levels, which is a point to consider.

The good news is, there are plenty of keto-friendly alternatives to cashews, like almonds, macadamia nuts, pecans, and walnuts. These alternatives not only have lower carb contents but also offer a range of nutritional benefits, making them excellent substitutes.
