What are Polyphenols? Our Functional Medicine Toronto Clinic Answers


At our functional medicine Toronto practice, it’s not uncommon for us to recommend polyphenols to patients. After all, these compounds are connected to a wide variety of health benefits!

So, what exactly are polyphenols? These are plant-based molecules with antioxidant properties. As antioxidants, they’re able to nullify free radicals that are known to trigger cellular damage. 

Scientists are aware of the importance of polyphenols – especially how these compounds can aid in preventing chronic disease – through countless studies: “The chief reason for this interest is the recognition of the antioxidant properties of polyphenols, their great abundance in our diet, and their probable role in the prevention of various diseases associated with oxidative stress, such as cancer and cardiovascular and neurodegenerative diseases,” explains an article from The American Journal of Clinical Nutrition. 

In this blog post, we highlight how these compounds can benefit your health status:

  • They might offer cognitive improvements: Polyphenols are naturally formed in concord grape juice. In one study, participants were given this juice and verbal learning was significantly enhanced. “These preliminary findings suggest that supplementation…may enhance cognitive function for older adults with early memory decline …” says an article from the British Journal of Nutrition
  • Contains anti-inflammatory functions: Oxidative stress can lead to chronic inflammation. But according to an article from Oxidative Medicine and Cellular Longevity, clear, evidence-based information has shown that polyphenols can tackle oxidative stress, which might help manage “… different inflammatory mediators such as metabolites derived from arachidonic acid, various peptides, excitatory amino acids, and cytokines.”
  • May have the potential to improve cardiovascular health: Further research is necessary, though polyphenols might minimize your risks for heart disease. Scientists deem that Inflammation is a contributing factor for cardiovascular health issues, and polyphenols are already naturally anti-inflammatory. 
  • Shows promise in managing blood sugar levels: Polyphenols could contribute to lessening your risk for type II diabetes. The plant compounds might counteract starch from breaking down into sugars, which could minimize blood sugar spikes. Also, polyphenols might activate insulin secretion, which helps stabilize blood sugar levels.
  • Could contribute to cancer prevention: Scientists are attempting to understand the significance of polyphenols as “potential candidates for the discovery of anticancer drugs,” explains a Nutrients article. So far, some research has suggested that polyphenols “…can exert anticancer effects through a broad range of mechanisms, that includes cancer cell removal by modification of signaling pathways, inhibition of cell cycle events, and apoptosis induction,” confirms a Translational Cancer Research piece.  

Taking polyphenols for optimal function

Truly, polyphenols can offer enrichment to our long-term health. So how can they be consumed? At our Toronto practice, a functional medicine practitioner can guide you on adding them to your diet and/or supplemental regime. Some foods known to be rich in polyphenols include: berries, olive oil, black currants, beans, spinach, black and green tea, and nuts. Note: some polyphenol supplements might interact or impede on iron and folate absorption. Our healthcare providers can help determine if polyphenol supplements are suited for you using the functional medicine model. Continue reading to learn how to book your first session.
