New Studies: Cranberry Protects the Heart and Manages Blood Sugar Levels

Recent studies show that cranberry, the tiny red fruit known for its positive effect on one’s overall health and wellbeing, improves heart health—strengthening long perceived theories about the cranberry’s health benefits.

The Heart of the Matter The study looked at what happens when overweight but otherwise healthy individuals drank a cranberry beverage containing heart-healthy polyphenols. After two glasses (15.2 oz.), the volunteers showed healthier blood sugar levels without spikes or dips, changes often attributed to cravings or fatigue. The health benefits were sustained if they continued drinking two glasses on a regular basis.

  • After eight weeks of daily cranberry beverage consumption, individuals had increased levels of high-density lipoprotein (HDL) cholesterol, which helps maintain artery health by sweeping up bad cholesterol.
  • Participants also showed better blood vessel function and less oxidative stress, which can prevent inflammation, a condition often linked to heart disease, obesity, diabetes and arthritis.
  • Researchers also noted that the cranberry beverage helped maintain blood sugar levels within normal range over the eight week study.

By isolating and applying the natural purifying element in cranberries – proanthocyanidins or PACs – these extract studies are making a case for how this natural compound, unique to cranberries, can improve overall health. Snapshots of the findings are below.

  • Cellular Health: Pre-clinical research indicates that PACs found in cranberries may have properties that limit cancer cell growth. While further studies are warranted, the latest findings suggest great potential for the cranberry’s anticancer activity. [3]

Prebiotics: Move over yogurt! Cranberries have now been linked to prebiotic qualities, boosting the number of good bacteria living in the gut. That’s according to a team out who found that when cranberry extract rich in PACs was left overnight with bacteria commonly found in the gastrointestinal tract and human colon cancer cells, the PACs played an anti-inflammatory and antioxidant role, promoting the good bacteria’s activity on the colon cancer cells. Heart Protection: To explore how the natural compounds in cranberries can protect the body against harmful substances, a team of scientists soaked heart muscle cells in cranberry extract for six hours. The result? The cranberry extract lowered the amount of tissue-damaging enzymes, called MMPs, which have been linked to heart disease, tumor growth and arthritis. “While additional studies are warranted to truly understand the role of PACs in cell health and heart protection and in boosting the activity of good gut bacteria, initial research yields promising indications that cranberry PACs in the form of an extract can be leveraged as an effective way to improve whole body health,” said Christina Khoo, PhD, Director, Research Sciences, Ocean Spray.
