Chokeberries May Help Weight Loss, Inflammation
When was the last time you ate chokeberries? If you are not familiar with these tasty, nutritionally rich fruits, you may want to be, especially because they offer a variety of health benefits, including helping with weight loss and reducing inflammation.
Chokeberries (Aronia melanocarpa) are small (about 1 cm) fruits that have relatively thick, pigmented skin that come in several colors, including black, red, and blue. The red are sweeter than the black ones, and both the black and blue chokeberries are richer in the antioxidants anthocyanins than the red.
Chokeberries contain many different anthocyanins, including quercetin, epicatechin, peonidin, petunidin, among others. According to one source, the total anthocyanin content in chokeberries is 1,480 mg per 100 grams of fresh berries. They also have one of the highest ORAC (oxygen radical absorbency capacity; a measurement of antioxidant strength) values of any food: 16,062 micromoles of Trolox Equivalents, or about three times greater than blueberries. Scientific studies have shown that chokeberries offer protection against cancer, neurological diseases, inflammation, diabetes, bacterial infections, and aging.
In this newest study, scientists from the US Department of Agriculture in Beltsville, Maryland, analyzed the impact of chokeberry extract on 18 prediabetic rats. The rats were randomly assigned to receive either pure water or water spiked with low or high levels of chokeberry extract for six weeks. After six weeks, the scientists compared body weight, body fat, blood glucose regulation, and markers for inflammation in the rats.
