One of the most important discoveries in recent health research is that inflammation contributes to a wide range of conditions—from well-known diseases such as rheumatoid arthritis to less expected ones like depression, Alzheimer’s, cancer, and cardiovascular disease.
How inflammation works
Inflammation plays a central role in both initiating and accelerating cardiovascular disease. It also contributes indirectly: chronic inflammatory conditions such as arthritis, autoimmune disorders, and diabetes increase the likelihood of developing heart disease.
Decker Weiss, NMD, FASA, a naturopath and cardiologist at the Weiss Center for Health and Medicine, explains that elevated insulin, high blood sugar, trans fats, and homocysteine damage and inflame the endothelium—the lining of blood vessels—starting the process that leads to coronary artery disease.
Atherosclerosis, the thickening and hardening of arteries, is a clear example of inflammation’s impact on the heart. Current evidence shows that every stage of atherosclerosis—from endothelial dysfunction to plaque formation, calcification, and eventual rupture—is driven by inflammatory cytokines and interleukins, signaling proteins that promote inflammation in tissues and blood vessels.
How nutritional heart helpers work
Inflammation impairs endothelial function, which contributes to vascular disease and atherosclerosis. Certain foods contain compounds that help reduce inflammation and support blood vessel health.
Garlic has compounds that may help reduce inflammation, improve endothelial function, and increase vascular elasticity, potentially lowering the risk of cardiovascular disease when used as part of an overall heart-healthy approach.
Dark chocolate—in modest amounts and with a high cocoa content—contains flavonoids that can decrease inflammation and enhance endothelial function, improving blood vessel dilation and thereby reducing cardiovascular risk.
Diet and inflammation
A large study investigating diet and heart disease found that eating more pro-inflammatory foods was associated with a substantially higher risk of cardiovascular events. Participants with diets higher in inflammatory foods showed a 38 percent greater risk of cardiovascular disease overall, a 46 percent higher risk of coronary heart disease, and a 28 percent increased risk of stroke.
Inflammatory foods commonly include red and processed meats, organ meats, refined carbohydrates, and sweetened beverages.
Anti-inflammatory foods that support heart health include leafy green vegetables, dark yellow vegetables, fruit, whole grains, tea, coffee, and moderate amounts of wine. These plant-based choices provide antioxidants, fiber, and healthy plant compounds that reduce inflammation and improve cardiovascular markers.
For these reasons, shifting toward a predominantly plant-based diet can lower the risk of developing or worsening cardiovascular disease.
Good fats, bad fats
One reason plant-forward diets are anti-inflammatory is the type of fats they emphasize. Plant-based foods tend to be higher in monounsaturated and polyunsaturated fats—fats that can reduce blood clotting and inflammation. In contrast, many animal-derived foods contain higher levels of saturated fat, which can promote inflammation and increase clotting.
Just five percent helps
Even a relatively small change—replacing just five percent of total calories from saturated fat with monounsaturated or polyunsaturated fats—can lower the risk of mortality related to cardiovascular disease.
Supplements for the heart
Several natural supplements have anti-inflammatory properties and may support cardiovascular health when used appropriately alongside diet and medical care. These include:
- curcumin
- gingerroot
- ginkgo
- grapeseed extract
- green tea
- hawthorn
- hibiscus
- olive leaf extract
- omega-3 fatty acids
- pine bark extract
- pomegranate
- quercetin
- vitamins C and D
Two practical takeaways emerge from the link between inflammation and heart health. First, thoughtful dietary changes and selected natural supplements can be useful components of a strategy to prevent and manage cardiovascular disease. Second, paying attention to early warning signs—such as persistent joint pain, digestive problems, blood sugar irregularities, fatigue, insomnia, and depressive symptoms—can prompt earlier evaluation and intervention to reduce long-term cardiovascular risk.
