Cranberries and Your Health: What the Latest Research Shows
With sponsorship support from the British Columbia Cranberry Marketing Committee, Dr. Amy Howell presented research about the health benefits of cranberries in Philadelphia to 110 Registered Dietitians.
Cranberry has distinguished itself as a functional food with potent health benefits. It has a rich folklore history of use as an antimicrobial, especially for prevention of urinary tract infections. This little red berry is gaining attention in the research world for having a broad array of benefits, including compelling effects on the gut microbiome, which have been shown to influence cardiovascular and diabetic risk factors. The bacterial anti-adhesion effects of cranberry are not limited to prevention of urinary tract health but extend to the stomach for control of ulcer-causing bacteria and to the oral cavity for positive effects on periodontal disease.The influence of antibiotic resistance and prescribing of antibiotics to treat these bacterial infections was discussed along with how including cranberry in the diet as a preventative could reduce the pace of resistance development. The way that cranberry is consumed (dosage and product form) can influence the overall bioactivity and resulting health benefits.
Cranberry Polyphenols: Natural Weapons against Dental Caries
Bioactive components of the American cranberry (Vaccimium macrocarpon) are thought to weaken several pathways to cariogenesis. This recent review highlights the effect cranberry polyphenols have on enzymes and proteins, as well as the environment, known to increase risk for dental caries. Laboratory studies suggest flavonoids present in cranberries such as quercetin, myricetin, kaempferol and a-linked proanthocyanidins have a role in limiting plaque production, decreasing acid promotion and interfering with the ability of bacteria to thrive in low pH environments. Clinical research is necessary to determine if the anticipated preventive properties of cranberry products translate to cavity prevention in high-risk individuals and populations.
