Cranberry juice, known for its urinary tract infection benefits, may also be a valuable addition to a healthy gut, according to Dr. Karan Rajan, a gastro-intestinal surgeon.
Cranberries are rich in polyphenols, natural plant antioxidants that combat inflammation and promote gut health. These polyphenols, particularly Proanthocyanidins, suppress the growth of harmful bacteria, leading to a healthier gut microbiome.
Dr. Rajan emphasizes that whole cranberries or blended smoothies offer a more complete source of these beneficial nutrients due to their fiber content. However, cranberry juice remains a convenient option for many, providing a boost of plant pigments.
A 2016 study revealed that cranberries can inhibit the growth of Helicobacter pylori (H. pylori) bacteria, which can cause stomach ulcers. Additionally, animal studies suggest that cranberries' antioxidant and anti-inflammatory properties may protect against colon cancer.
Dr. Rajan recommends incorporating a variety of colorful fruits and vegetables into your diet to maximize the intake of different polyphenols, each with unique benefits for the gut microbiome.
