21. Fun Facts
A Superberry in the True Sense
Did you know that Haskap berries are a powerhouse of nutrients, truly deserving the title of a “superberry”? Research has shown that these berries contain a significantly higher concentration of cyanidin-3-O-glucoside (C3G), a potent antioxidant, compared to a range of popular North American berries including blueberries. Specifically, Canada-bred haskap varieties have been found to contain between 68 and 649 mg of C3G per 100 g of fresh weight, which is considerably higher than the C3G content in blueberries, which is about 3.0 mg per 100 g of fresh weight.
Vitamin C Rich
But that’s not all! Haskap berries are also a rich source of vitamin C, with some varieties containing between 29 and 187 mg of vitamin C per 100 g of fresh weight. To put this in perspective, this is significantly higher than the vitamin C content in oranges, which contains about 53.2 mg per 100 g of fresh weight. This high vitamin C content not only positions haskap as one of the richest sources of this vital nutrient but also suggests that it can offer greater health benefits compared to other commonly consumed berries .
A Berry with a Promising Future
Given these impressive nutritional credentials, it’s no surprise that haskap berries are currently a hot topic in the field of nutritional research. Scientists are keen to explore the full range of health benefits that this “superberry” can offer, with current research suggesting potential antioxidant, anti-inflammatory, and cardio-protective effects, among others. It’s an exciting time to be a haskap enthusiast, as we watch this humble berry rise to prominence as a potential new superfruit in the health and wellness sphere .
