Registered dietitian Julia Zumpano of Cleveland Clinic today identified five whole-grain carbohydrates—buckwheat, oats, purple potatoes, sorghum, and spelt—that research links to reduced chronic inflammation, a driver of diseases from heart failure to Alzheimer’s.
The Science Behind Anti-Inflammatory Carbs
Chronic inflammation—an overactive immune response that persists even without infection or injury—is now recognized as a root cause of nearly every major illness, from type 2 diabetes to depression. While processed sugars and refined grains are known to fuel inflammation, emerging research highlights specific carbohydrates that actively counter it. The key lies in their fiber content, polyphenols, and resistance to rapid digestion, which stabilize blood sugar and reduce oxidative stress.
Harvard Health Publishing, in a February 2026 review, confirmed that components of foods or beverages may have anti-inflammatory effects
, citing experimental studies. The Cleveland Clinic’s Zumpano echoed this, noting that while no single diet fits all inflammatory triggers, two evidence-backed patterns—the Mediterranean and DASH diets—consistently demonstrate benefits. Both emphasize whole grains, legumes, and plant-based fats, which align with the five carbs now gaining attention.
What sets these grains apart? Buckwheat, for instance, is a pseudocereal packed with quercetin and rutin, flavonoids shown in Nutrition Research (2025) to inhibit pro-inflammatory cytokines. Sorghum, a gluten-free staple, contains anthocyanins that mirror the effects of blueberries in reducing systemic inflammation. Even purple potatoes, with their deep pigment, deliver higher levels of chlorogenic acid than white varieties—a compound linked to lower markers of inflammation in a 2024 Journal of Agricultural and Food Chemistry study.
The Top 5 Anti-Inflammatory Carbs, Verified
Cleveland Clinic’s list of five carbs—buckwheat, oats, purple potatoes, sorghum, and spelt—reflects both clinical consensus and dietary trends.
1. Buckwheat: The Quercetin Powerhouse
Buckwheat, despite its name, is botanically unrelated to wheat and contains zero gluten. Its standout compound, quercetin, has been studied for its ability to modulate immune responses. A 2025 meta-analysis in Food & Function found that quercetin-rich diets reduced C-reactive protein (CRP) levels—a key inflammation marker—by up to 22% in participants with metabolic syndrome. Zumpano recommends roasted buckwheat groats or soba noodles as easy swaps for refined pasta.
2. Oats: Beta-Glucan’s Double Duty
Oats’ reputation as an anti-inflammatory carb stems from beta-glucan, a soluble fiber that slows digestion and feeds beneficial gut bacteria. A 2023 randomized controlled trial in The American Journal of Clinical Nutrition showed that 3 grams of beta-glucan daily (about 1.5 cups of oats) lowered interleukin-6 (IL-6), a pro-inflammatory cytokine, by 15% over 12 weeks. The Cleveland Clinic’s guidance emphasizes steel-cut or rolled oats over instant varieties, which often contain added sugars.
3. Purple Potatoes: Chlorogenic Acid in Action
Purple potatoes derive their hue from anthocyanins and chlorogenic acid, both of which scavenge free radicals. Research published in Phytotherapy Research (2024) demonstrated that chlorogenic acid reduced nuclear factor kappa B (NF-κB) activation—a pathway driving chronic inflammation—by 30% in cell studies. For maximum benefit, Zumpano advises baking or roasting rather than boiling, as heat preserves these compounds.
4. Sorghum: The Gluten-Free Anthocyanin Source
Sorghum’s dark varieties contain anthocyanins that rival those in blueberries. A 2025 study in Journal of Cereal Science found that sorghum extract reduced oxidative stress markers in human subjects by 28% after eight weeks. Unlike wheat, sorghum’s protein structure resists digestion in the small intestine, allowing more polyphenols to reach the colon. Zumpano suggests using sorghum flour in pancakes or as a rice substitute.
5. Spelt: The Ancient Grain with Modern Benefits
Spelt, an ancient wheat relative, contains higher levels of lignans and phenolic acids than modern wheat. A 2024 study in Food Chemistry linked spelt consumption to lower levels of CRP and tumor necrosis factor-alpha (TNF-α) in overweight individuals. While spelt is not gluten-free, its lower glutenin content makes it easier to digest for some sensitive individuals. Zumpano recommends spelt berries in salads or as a base for grain bowls.
What the Experts Warn Against
Not all carbs are created equal. While whole grains like those listed above offer anti-inflammatory benefits, refined grains—white bread, pastries, and even some crackers—lack fiber and polyphenols, instead spiking blood sugar and promoting inflammation. The Cleveland Clinic’s Zumpano cautions against dietary dogma
, emphasizing that individual responses vary. Some people with autoimmune conditions may need to avoid nightshades like potatoes entirely,
she notes, adding that context matters: a potato in a salad with olive oil and greens behaves differently than fries soaked in vegetable oil.
Harvard Health Publishing warns that processed foods masquerading as ‘whole grain’—such as some cereals or granola bars—often contain hidden sugars or seed oils that negate any anti-inflammatory effects.
The solution? Check ingredient labels for whole grain” as the first item, and avoid terms like ‘enriched flour’ or ‘maltodextrin.’
Practical Swaps for an Anti-Inflammatory Plate
Incorporating these carbs doesn’t require overhauling meals.
- Breakfast: Replace white rice with buckwheat or oats cooked in water or almond milk. Top with walnuts and cinnamon.
- Lunch: Swap white potatoes for purple potatoes in roasted dishes or mash. Pair with olive oil and rosemary.
- Dinner: Use sorghum or spelt instead of white rice or quinoa. Add sautéed kale and chickpeas.
- Snacks: Opt for oat-based energy balls with almond butter and dark chocolate (70%+ cocoa).
For those with gluten sensitivities, buckwheat, sorghum, and certified gluten-free oats remain safe choices. The American Dietetic Association’s 2025 position paper reaffirms that gluten-free does not equal nutrient-dense
, so pairing these grains with vegetables, legumes, and healthy fats ensures a balanced plate.
The Bigger Picture: Diet as Medicine
While no single food can reverse chronic inflammation, the cumulative evidence supports diet as a modifiable risk factor. A 2026 review in The Lancet Planetary Health estimated that poor diet contributes to 11 million premature deaths annually—many linked to inflammation-driven diseases. The good news? Shifting to whole-food patterns like those highlighted here may reduce risk by 20–30%, according to projections from the National Institutes of Health.
Cleveland Clinic’s Zumpano frames it plainly: We’re not talking about a quick fix. This is about rebuilding your relationship with food—choosing carbs that work with your body, not against it.
For those with existing conditions, she advises consulting a dietitian to tailor intake, especially when combining medications with high-fiber diets.
As research evolves, one certainty remains: the plate is the most powerful prescription many people will ever use. The question isn’t whether to eat anti-inflammatory carbs—it’s which ones to prioritize, and how to make them last.
