Berries give you a gratifying burst of color and flavor. Berries are a keto-friendly fruit option, and they deliver a range of health benefits. Let’s discuss the benefits of berries, why you should include berries in your ketogenic diet, and some palatable berrylicious recipes.
Here are just some of the many health benefits of eating berries on any diet, especially a ketogenic diet.
Berries are rich in antioxidants, which help prevent unstable molecules called free radicals from damaging your cells and leading to oxidative stress [1]. Berries contain antioxidants like ellagic acid, resveratrol, and anthocyanins that protect your cells and might reduce your risk of various diseases [2] [3]. The antioxidants in berries might help reduce oxidative stress [4] [5].
Blueberries are a hit in the health world because they’re low in calories, keto-friendly in moderation, and packed with antioxidants and nutrients. Studies show blueberries contain the most antioxidants compared to all commonly consumed vegetables and fruits. 3.5 ounces (100 grams) of blueberries has up to 9.2 mmol of antioxidants [6] [7].
Some studies suggest berries might protect your cells from high blood sugar levels, increase insulin sensitivity, and reduce insulin and blood sugar response to high-carb meals. These effects seem to happen in both healthy people and those with insulin resistance [8] [9] [10].
For example, in one six-week study, obese people with insulin resistance who drank a blueberry smoothie twice daily had more significant improvements in insulin sensitivity compared to those who consumed berry-free smoothies [11].
Berries are an excellent fiber-source. Studies show fiber might help with weight loss, digestion, and constipation [12] [13].
The high fiber content also means berries are low in digestible or net carbohydrates, making them a keto-friendly choice. For example, 1 cup of blackberries provides around 7 grams of net carbs. 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 also have a fairly low glycemic index (GI) score of 40. [14] [15].
When it comes to nutrients, berries certainly deliver. Berries, particularly strawberries, are high in vitamin C, with 1 cup (150 grams) of strawberries providing an impressive 150% of the RDI for vitamin C. Blackberries are another nutrient-rich example. Blackberries are rich in manganese, copper, folate, and vitamin K1. Berries are also some of the lowest-calorie fruits around [16] [17].
Berries exhibit powerful anti-inflammatory properties. Excessive and long-term inflammation is believed to contribute to a plethora of health conditions, including heart disease, obesity, and cancer. The antioxidants in berries might help reduce inflammatory markers [18] [19] [20] [21].
Berries enhance plenty of dishes, from breakfast and brunch to dessert. Berries complement a salad or a Greek yogurt. Use berries to sweeten keto dishes and make smoothies, keto cakes, ice creams, and more.
