Purple potatoes are rich in anthocyanins, a type of antioxidant that may offer several health benefits, including improved eye and heart health, reduced inflammation, and a lower risk of chronic diseases. They also contain potassium, which aids in blood pressure regulation. However, they are also high in starch and carbohydrates, which can impact blood sugar levels and make it challenging to maintain ketosis. So, can you eat purple potatoes on a keto diet? While potatoes are generally not considered keto-friendly due to their high carb content, some suggest that purple potatoes, in moderation, may be included as part of a cyclical or targeted keto diet approach.

Purple potatoes are high in carbs, which makes it difficult to maintain ketosis
Potatoes are generally starchy and high in carbs, making it difficult to maintain ketosis. So, the answer is no—potatoes are not keto. The USDA reports that a 100-gram serving of potatoes contains around 15.4 grams of carbohydrates. However, the number of carbs varies depending on the type of potato. For example, three Melissa's Potatoes Purple contain 26 grams of net carbs.
While purple potatoes have a lower glycemic index than regular potatoes, eating large amounts can still impact blood sugar levels. The glycemic index (GI) is a measure of how much a food increases your blood sugar, and it ranges from 0 to 100. A GI greater than 70 is considered high. Purple potatoes have a GI of 77, while yellow and white potatoes have GIs of 81 and 93, respectively.
Because of their high carbohydrate content, all potato varieties affect blood sugar levels. However, purple potatoes may have a lesser impact than other types due to their high concentration of polyphenol plant compounds, which may reduce starch absorption in the intestines.
If you are on a keto diet or other low-carb diets, it is recommended to limit your consumption of purple potatoes. To maintain ketosis, it is best to eat foods that do not raise blood sugar or cause a slow rise, such as lettuce and cucumbers. However, if you want to include potatoes in your keto diet, you can try a cyclical or targeted keto diet.

Purple potatoes have a lower glycemic index than regular potatoes, but can still impact blood sugar levels
The glycemic index (GI) is a measure of how much a food increases your blood sugar. It ranges from 0 to 100, and a GI greater than 70 is considered high. Purple potatoes have a lower glycemic index than regular potatoes, with a GI of 77 compared to 81 for yellow potatoes and 93 for white potatoes. This means that purple potatoes may have a less pronounced effect on blood sugar levels than other potato varieties.
However, it is important to note that purple potatoes can still impact blood sugar levels, especially when consumed in large amounts. This is because all potato varieties contain carbohydrates, which can affect blood sugar levels. Therefore, if you are on a keto diet or trying to maintain ketosis, it is generally recommended to limit your consumption of purple potatoes, as they are still considered a high-carb food.
That being said, purple potatoes offer several nutritional benefits. They are rich in polyphenol antioxidants, including anthocyanins, which are linked to improved eye and heart health and a reduced risk of chronic diseases. Purple potatoes also contain potassium, which can help regulate blood pressure. Additionally, some studies suggest that purple potatoes may have cancer-fighting properties and can help prevent blood clots.
To include purple potatoes in your diet while maintaining ketosis, it is recommended to keep portion sizes small and pair them with a variety of other non-starchy vegetables as part of a healthy, well-rounded diet. It is also suggested that purple potatoes can be consumed during higher-carb days in a cyclical keto diet or around workouts as part of a targeted keto diet.

Purple potatoes are rich in polyphenol antioxidants, which may reduce the absorption of starches
Potatoes are generally starchy and high in carbs, making it difficult to maintain ketosis. Therefore, potatoes are not considered keto-friendly. However, purple potatoes, a type of root vegetable, offer a range of nutritional benefits that set them apart from regular potatoes.
Purple potatoes are rich in polyphenol antioxidants, specifically anthocyanins, which are also found in blueberries and blackberries. Anthocyanins are associated with improved eye and heart health and a reduced risk of chronic diseases, certain cancers, and diabetes. The polyphenol compounds in purple potatoes may work similarly to blood pressure-lowering medications, helping to relax and strengthen blood vessels and reduce arterial stiffness.
The high concentration of polyphenol plant compounds in purple potatoes may decrease starch absorption in the intestines, thereby minimizing their impact on blood sugar levels. This is supported by a study that found men who ate purple potatoes instead of white potatoes daily for six weeks experienced less inflammation and higher levels of antioxidants. Additionally, an animal study showed that feeding purple potato extract to rats improved glucose tolerance and short- and long-term blood sugar levels.
While purple potatoes have a lower glycemic index than regular potatoes, they can still impact blood sugar levels, especially in large amounts. Therefore, for those on a keto diet or managing diabetes, it is recommended to consume purple potatoes in moderation, keeping portion sizes small and pairing them with non-starchy vegetables.

Purple potatoes are a good source of potassium, which helps to regulate blood pressure
Potatoes are generally starchy and high in carbs, which can make it difficult to maintain ketosis. Therefore, potatoes are not considered keto-friendly. However, purple potatoes, in particular, offer a range of health benefits that may make them a better option for those on a keto diet than regular or white potatoes.
Purple potatoes are a good source of potassium, which is a nutrient that helps regulate blood pressure. A small 4-week study found that consuming six to eight purple potatoes twice daily reduced participants' systolic and diastolic blood pressure. The high concentration of potassium in purple potatoes is believed to be a contributing factor to this blood pressure-lowering effect.
Additionally, purple potatoes are rich in polyphenol antioxidants, specifically anthocyanins, which are linked to a range of health benefits. These antioxidants may help to reduce inflammation and improve eye and heart health, as well as lower the risk of chronic diseases. The polyphenol compounds in purple potatoes have also been found to work similarly to some blood pressure-lowering medications, further contributing to their blood pressure-regulating properties.
While purple potatoes offer these health benefits, it is important to remember that they still contain carbohydrates and can impact blood sugar levels. Therefore, if you are on a keto diet or aiming to control your blood sugar, it is advisable to consume purple potatoes in moderation and pair them with non-starchy vegetables.

Purple potatoes are not keto-friendly, but Carisma potatoes can be a lower-carb option
Purple potatoes are not keto-friendly due to their high carbohydrate content. According to one source, a 100-gram serving of potatoes contains around 15.4 grams of carbohydrates. This can make it difficult to maintain ketosis, a state where your body burns fat for energy instead of carbohydrates.
While purple potatoes have a lower glycemic index than regular potatoes, indicating a slower rise in blood sugar, consuming large amounts can still impact blood sugar levels. Therefore, they should be consumed in moderation, especially by individuals with diabetes.
However, potatoes are not entirely off the table for those following a keto diet. Carisma potatoes, which are produced by cross-breeding certain potato seeds, have the fewest total carbohydrates and net carbs per serving compared to other potato varieties. This makes Carisma potatoes a lower-carb option that can be incorporated into a keto diet while still enjoying the benefits of potatoes.
It is important to note that the keto diet allows for some flexibility. For example, potatoes can be included during higher-carb days in a cyclical keto diet or around workouts as part of a targeted keto diet if the total net carbs remain within the recommended range.
Additionally, purple potatoes offer several nutritional benefits. They are rich in antioxidants, particularly anthocyanins, which are linked to improved eye health, healthier cholesterol levels, and a reduced risk of chronic diseases, certain cancers, and heart disease. Purple potatoes also contain potassium, which aids in regulating blood pressure.
