Anyone who wants to achieve optimal health in 2026 needs to include "managing inflammation" in the to-do list. Inflammation in the body not only saps energy and promotes pain, but is a major contributor to most diseases. While not all diseases are directly caused by inflammation, inflammation is a common underlying factor in most health conditions. Ironically, some short-term inflammation can be good. It is the body's natural response to injury or infection--helping to promote healing. However, chronic inflammation is a completely different ballgame. It can lead to many of the common "top killer" diseases in the world. Inflammation and disease Diseases associated with inflammation include: Autoimmune diseases like rheumatoid arthritis and lupus; cardiovascular diseases like atherosclerosis; metabolic disorders like diabetes; neurological conditions like Alzheimer's; and chronic pain disorders like fibromyalgia. A list of diseases that are not directly linked to inflammation is substantially smaller. It includes genetic disorders, like cystic fibrosis, and infections where the primary cause is a pathogen rather than an inflammatory response. Fortunately there are many lifestyle choices and supplement regimens that can help lower inflammation. And just in time for a 2026 new year's resolution, a new study is highlighting one simple nutrient intake increase that can help the body in the daily fight against inflammation: polyphenols. Polyphenols defined Polyphenols are a group of more than 8,000 naturally occurring compounds found in various plant foods. They are known for their antioxidant properties, which help neutralize free radicals circulating in the body. This neutralization contributes to reduced inflammation and a reduction of chronic disease risk. Types of polyphenols include flavonoids, phenolic acids, polyphenolic amides, and others. Perhaps the most recognized polyphenol today is resveratrol—made famous by numerous headlines touting it as the life-extending nutrient in red wine. Study links polyphenol-rich diet to lower inflammation and CVD risk In a study published in BMC Medicine in November 2025, researchers at King's College London confirmed that higher levels of polyphenol metabolites in the blood were associated with lower cardiovascular risk scores. To reach this conclusion, the researchers followed 3,100 twins for over a decade while analyzing dietary intake and urinary metabolites. While noting the method of their research was the first of its kind, the researchers said measuring these metabolites provided a more objective and accurate reflection of dietary intake than questionnaires alone—making the findings more reliable. Polyphenols have been long celebrated for numerous health benefits, but the evidence pointing to cardiovascular benefits has accumulated at a slower pace. Researchers in the current study noted that earlier studies have already shown that polyphenols can improve the function of the blood vessel lining. This helps blood flow smoothly and prevents platelets from clumping excessively—reducing the risk of clotting. A primary study issue is that researchers have historically struggled to accurately assess polyphenol intake in free-living populations. This is because most dietary assessment tools have not been validated for estimating polyphenol intake; moreover, databases which provide nutritional information for foods often lack detailed information on polyphenol content. To address these limitations, the researchers created a Polyphenol Diet Score. The scoring is based on dietary intake of 20 different high-polyphenol foods. The researchers then compared these scores with urinary polyphenol metabolites, making it the first study to comprehensively assess polyphenol intake and cardiovascular health using these methods. Blood pressure and cholesterol readings were also taken, which were utilized in determining cardiovascular disease risk based on an industry-accepted Atherosclerotic Cardiovascular Disease Risk Score system. Study findings Ultimately, the detailed tracking revealed that people who had higher Polyphenol Diet Score numbers had a lower risk of heart disease. Specifically, a 10-unit increase on the Polyphenol Diet Score reduced the risk of heart disease by 8.5%. And the good news didn't end there—even modest increases in polyphenol intake were shown to have a positive impact. High intake of flavonoids and phenolic acids appeared to be particularly beneficial; however, the researchers noted that consuming a diverse array of polyphenol-rich foods was a better predictor of heart health than eating any single food or compound alone. This finding suggests a potential synergistic effect when eating a variety of polyphenol foods.
