Berries are colorful, juicy, antioxidant-rich, refreshing, and keto-friendly…assuming you don’t eat two whole cartons all at once! When it comes to fruits on keto, berries are an excellent choice to satisfy your sweet tooth and stay in ketosis!
Berries on Keto
From strawberries and blackberries to blueberries and raspberries, berries are lower in carbohydrates compared to most other fruits, making them a better choice for the ketogenic diet.
1 cup of blackberries provides around 7 grams of net carbs. Blackberries are tart and sweet and full of minerals and vitamins like C, K, and manganese. Vitamin C is important for healing wounds, regenerating skin, and forming blood vessels, bones, and connective tissue. Vitamin C helps you fight illness and boosts your immune system. Vitamin C acts as an antioxidant in your body and can reduce oxidative stress that leads to cancer and disease. More research is necessary, but studies show vitamin C might help with cancer [1,2]. Blackberries are also a good source of fiber, which can help relieve digestive issues like constipation. When you eat fiber, you feel fuller for longer, which might help with weight loss. Fiber is a fuel to nourish healthy bacteria (probiotics) in your digestive system. Berries like blackberries might also improve brain health and prevent memory loss due to the antioxidants that fight free radicals and alter the communication of brain neurons. One study showed blackberry extract has anti-inflammatory and antibacterial properties against certain types of bacteria that can lead to oral disease, suggesting blackberry extract might prevent and control cavities and gum disease [3,4].
Like other berries, strawberries are also popular in various desserts, jellies, and jams. The humble yet vibrant red strawberry is also a summer staple and an excellent source of vitamin C, manganese, potassium, folate, and more. Strawberries are rich in plant compounds and antioxidants that might benefit your heart and blood sugar levels [5,6,7].
Strawberries are around 91% water, 7.7% carbohydrates, 0.7% protein, and 0.3% fat. 1 cup of strawberries provides less than 9 grams of net carbs. The carbs in strawberries come from simple sugars, such as fructose and glucose, but the high fiber content makes them a keto-friendly choice. Strawberries have a fairly low glycemic index (GI) score of 40.
Strawberries also provide plant compounds like pelargonidin, which is responsible for the bright red color [8,9].
Blueberries are marketed as a superfood for good reason. Blueberries provide antioxidants, beneficial plant compounds, vitamins, and fiber. Compared to other berries, blueberries have the highest antioxidant content [10,11,12].
Blueberries provide small amounts of protein and fat and around 14% carbs and 84% water. On the glycemic index, blueberries have a relatively low score of 53. One cup of blueberries is 17.8 grams of net carbs and around 3.6 grams of fiber. Blueberries provide vitamin C, manganese, and other vitamins and minerals. They also contain many different anthocyanins — beneficial antioxidant plant compounds that can improve blood sugar and heart and brain health [13,14,15].
Ruby red raspberries are uniquely sweet and juicy and high in fiber! Raspberries are edible fruit from a plant species in the rose family. The red raspberry is the most common, but there are different types of raspberries, including purple, golden, and black. Raspberries have a short shelf life, and they’re only harvested during the summer and fall months. Raspberries provide powerful antioxidant compounds, magnesium, phosphorus, vitamin K and C, manganese, and more. Raspberries give you a whopping 8 grams of fiber per cup and 6.7 grams of net carbs, making them an excellent choice for a keto sweet treat. Studies also show raspberries and raspberry extracts have anti-inflammatory and antioxidative effects that might reduce the risk of chronic diseases, such as diabetes, obesity, and cancer [16,17,18].
