10 Foods That Cause Inflammation and What to Eat Instead
Transform everyday meals into healing forces with balanced, nutrient-rich choices.
Chronic inflammation is linked to numerous health issues, from heart disease and type 2 diabetes to some cancers and autoimmune disorders. While inflammation is a natural response that helps your body heal, it becomes problematic when persistent. What you eat strongly influences how much chronic inflammation your body experiences. Limiting specific pro-inflammatory foods can play a major role in improving overall health and well-being.
Understanding Inflammation: Friend and Foe
Inflammation is your body’s protective response to injury, infection, or irritants. However, unlike acute inflammation—which resolves once healing starts—chronic, low-level inflammation can persist for years, damaging tissues and organs. Diet is a key controllable factor in either minimizing or worsening this process. Incorporating nourishing, anti-inflammatory foods and limiting those that contribute to inflammation is crucial for long-term wellness.
What Are the Most Inflammatory Foods?
Research consistently points to certain foods and food groups as predominant triggers of chronic inflammation:
- Highly processed, refined, or fried foods packed with added sugars.
- Foods high in trans fats and certain types of saturated fat.
- Excess alcoholic beverages.
- Meats that are processed or red, especially when consumed frequently.
Below, explore the major offenders, the science behind their effects, and simple swaps for better health.
Candy and Sugary Sweets
Candies, gummies, chocolate bars, and other sugary treats may satisfy cravings but they are “sugar bombs” that can fuel inflammation. Scientific studies have linked excessive added sugars—prevalent in most candies—with increased inflammatory responses and development of chronic disease.
- Quickly spike blood glucose, leading to insulin resistance over time.
- Trigger release of pro-inflammatory cytokines in the body.
- Excess intake linked to higher risk of type 2 diabetes, obesity, and heart disease.
Tip: Limit candies and opt for fresh fruit or a small portion of dark chocolate (70% or higher cocoa) to satisfy your sweet tooth with beneficial antioxidants.
Fast Food
Fast food options, especially fried items like french fries and chicken nuggets, are loaded with unhealthy trans fats and refined carbohydrates. These contribute to several inflammatory pathways in the body.
- Contain trans fats, a known trigger for widespread inflammation.
- Fried foods are cooked in oils high in omega-6 fatty acids, which promote inflammation when not balanced by omega-3s.
- Often high in sodium, preservatives, and artificial additives—all of which fuel inflammation or stress vital organs.
What others are reading
Regularly consuming fast food is associated not only with cardiovascular issues but also with mental health (increased inflammation has been linked to anxiety and depression).
Tip: Prepare simple meals at home using fresh ingredients, or choose grilled, roasted, or baked options when eating out. Include a side salad or steamed vegetables instead of fries.
Processed Meats
Meats that have been salting, curing, smoking, or processed in any way—such as bacon, sausages, hot dogs, ham, and deli slices—pose a significant concern for inflammation and more severe long-term health consequences.
- High in saturated fats and chemical preservatives (like nitrites and nitrates).
- Regular consumption linked to elevated inflammation markers and a higher risk of certain cancers, especially colorectal cancer.
- Processing creates compounds that increase oxidative stress and inflammation.
Tip: Replace processed meats with poultry, fish, beans, or lentil-based dishes. Experiment with plant-based protein alternatives for variety.
Sweetened Snacks & Breakfast Foods
Breakfast cereals, pastries, granola bars, and flavored yogurts often seem healthy but usually contain high levels of added sugar and refined grains. These ingredients raise blood glucose levels rapidly, especially in those with glucose intolerance, leading to a chronic inflammatory state when consumed regularly.
- Spiking and crashing blood sugar promotes an ongoing inflammatory cycle.
- Products commonly labeled as ‘healthy’ still contain as much sugar as a typical dessert.
- Frequent intake associated with increased risk of metabolic syndrome and fatty liver disease.
Tip: Choose whole grain cereals with no added sugar, overnight oats, or Greek yogurt topped with fresh fruit, nuts, and seeds for more sustained energy and less inflammation.
Red Meat
While an occasional serving of red meat, such as lean beef or lamb, may fit in a balanced diet, frequent consumption—especially of fattier cuts—has been repeatedly associated with raised levels of inflammatory markers.
- High in saturated fat compounds that activate inflammatory responses.
- Cooking at high temperatures (grilling, frying) can create advanced glycation end products (AGEs) that further drive inflammation.
- Linked to increased risk of heart disease, colorectal cancer, and type 2 diabetes.
Tip: Choose poultry or fish more often, and limit red meat to occasional servings. When eaten, select lean cuts and cook at lower temperatures.
Alcohol
Moderate alcohol consumption may have some health benefits, but excess alcohol is a powerful driver of chronic inflammation throughout the body, particularly targeting the liver and gastrointestinal tract.
- Liver metabolizes alcohol into acetaldehyde, a toxic compound that triggers immediate inflammatory responses.
- Regular overconsumption disrupts gut bacteria and compromises immune function.
- Linked with increased risk of liver disease, certain cancers, and impaired brain function over time.
Tip: Stick to recommended daily limits: one drink per day for women, two for men. Avoid binge drinking and choose lower-alcohol beverages when possible.
White Flour and Refined Grains
Foods made from white flour, including white bread, many pastas, pastries, and crackers, are stripped of fiber and beneficial nutrients during processing. This leads to a rapid rise in blood glucose and insulin, driving systemic inflammation.
- Refined grains digest quickly, causing a spike in blood sugar and inflammatory markers like C-reactive protein (CRP).
- Lack of fiber impairs gut health, further contributing to chronic inflammation.
Tip: Replace white flour-based products with whole grain versions, such as brown rice, quinoa, whole wheat bread, and oats. These boost fiber intake and have a gentler effect on blood glucose.
Trans Fats and Some Seed Oils
Trans fats, often found in shelf-stable baked goods, margarine, and some fried fast-food items, have no redeeming nutritional value and are strongly linked to heightened inflammation.
- Promote the release of inflammatory chemicals in the body.
- Increase LDL (“bad”) cholesterol while lowering HDL (“good”) cholesterol.
- Raise the risk of cardiovascular and autoimmune diseases.
Note: Processed seed oils (such as corn, soybean, sunflower) are high in omega-6 fatty acids. While some omega-6 is necessary, excess intake relative to omega-3 fats can promote inflammation. Favor olive oil, avocado oil, or a small amount of nut oils for cooking.
Sugar-Sweetened Beverages
Sodas, sports drinks, sweetened teas, and energy drinks are leading sources of added sugar in many diets. Unlike whole foods, sugar in liquid form gives a rapid, pronounced glycemic spike and is strongly associated with both metabolic and inflammatory disease risk.
- Consumption linked to elevated markers of inflammation such as CRP and interleukin-6.
- Frequent intake leads to insulin resistance and fatty liver, key features of systemic inflammation.
Tip: Choose water, seltzer, herbal teas, or coffee (without sugar) most often. Flavor your water with slices of citrus, berries, or cucumber for interest.
Artificial Additives & Preservatives
Many packaged foods contain chemicals that extend shelf-life or enhance color and flavor—such as monosodium glutamate (MSG), sodium benzoate, artificial dyes, and emulsifiers. These substances aren’t always recognized as problematic in small amounts, but when consumed habitually they may disrupt gut bacteria and contribute to chronic inflammation.
- Some preservatives and emulsifiers have been shown in animal studies to trigger inflammatory intestinal disease and worsen metabolic health.
- Artificial colors and flavors may aggravate allergies and immune responses.
Tip: Check ingredient labels and choose products with fewer additives, or stick to simple, whole foods whenever possible.
How Inflammatory Foods Impact Health
Consuming a diet high in the above foods can have wide-reaching effects on your health, including:
- Increased risk of chronic diseases such as heart disease, stroke, diabetes, certain cancers, and neurodegenerative conditions.
- Promotion of weight gain and metabolic dysfunction (inflammation is both a cause and result of obesity).
- Intensified symptoms for those with autoimmune or inflammatory conditions, such as arthritis or inflammatory bowel disease.
- Potential negative effects on mental health and mood due to inflammation’s impact on neurotransmitters.
It’s never about total abstinence but about moderation. Your eating pattern should be built around nutrient-dense, minimally processed foods, while allowing room for occasional treats in reasonable portions.
What to Eat Instead: Building an Anti-Inflammatory Diet
Focusing on anti-inflammatory foods can help neutralize the effects of pro-inflammatory choices. An anti-inflammatory diet should prioritize:
- Colorful fruits and vegetables (rich in antioxidants and polyphenols)
- Whole grains and legumes
- Healthy fats, especially extra-virgin olive oil and omega-3 rich fish (salmon, sardines, mackerel)
- Nuts and seeds (chia, flax, walnuts, almonds)
- Lean proteins (poultry, fish, tofu, beans)
- Herbs and spices with proven anti-inflammatory effects (turmeric, ginger, garlic)
For more details, consult with a registered dietitian or healthcare provider specialized in nutrition.

Frequently Asked Questions (FAQs)
Q: Does eating a small amount of inflammatory foods matter?
A: Occasional consumption generally won’t cause chronic problems for most healthy people, but frequent or regular intake can contribute to cumulative inflammation. The key is balance and moderation.
Q: Are all fats inflammatory?
A: No. Monounsaturated fats (like those in olive oil and avocados) and omega-3 fatty acids (from fish and flaxseed) are anti-inflammatory. It’s primarily trans fats and an excess of omega-6 fatty acids that drive inflammation.
Q: Can certain foods reduce existing inflammation?
A: Yes. Foods rich in antioxidants (berries, leafy greens), fiber (whole grains, legumes), and healthy fats help to calm body-wide inflammation. Incorporating them regularly is linked to lower disease risk and better overall health.
Q: Is sugar from fruit inflammatory?
A: No. Naturally occurring sugar in whole fruit is paired with fiber and beneficial nutrients, making it safe and beneficial for most people. Added sugars found in processed foods and drinks are the concern.
Q: What are the easiest ways to start an anti-inflammatory diet?
A:
- Cook more meals at home using whole, minimally processed ingredients.
- Swap refined grains for whole grains whenever possible.
- Include a serving of vegetables with every meal.
- Use healthy oils (like olive oil) for cooking and salads.
- Limit sugary beverages and swap in flavored water or herbal tea.
