Wondering what foods cause inflammation? You’re in the right place. Inflammatory foods are among the worst foods you can consume.
First, I’ll discuss what inflammation is and how inflammatory foods damage the body. Then I’ll share the top 10 foods (and things in food) that cause inflammation the most. I’ll also share a list of other common inedible sources of inflammation because I know a lot of people still have inflammation even though they’re eating healthy.
Let’s dig in.
How Inflammatory Foods Damage the Body
Inflammation is a natural and necessary process that helps the body fight off infections, heal injuries, and repair damaged tissues. It’s the body’s way of protecting itself and initiating the healing process. When tissue is damaged or threatened by harmful stimuli the immune system responds by triggering inflammation to eliminate the threat and repair the damaged tissue.
However, chronic or excessive inflammation can have negative effects on both physical and mental health, as well as weight management. When you eat inflammatory foods or experience other causes of inflammation they can start to affect your health in so many detrimental ways because they literally damage tissues in the body. Here are the most common ways that inflammation & inflammatory foods damage the body affecting health and metabolism in the process.
Physical Health:
- Chronic Diseases: Prolonged inflammation is associated with the development and progression of various chronic diseases, including cardiovascular disease, diabetes, autoimmune disorders, neurodegenerative diseases, and certain types of cancer.
- Immune Dysfunction: Chronic inflammation can dysregulate the immune system, leading to increased susceptibility to infections and impaired immune function.
- Tissue Damage: Inflammatory processes can cause damage to healthy tissues and organs over time, contributing to tissue degeneration and dysfunction. Premature aging is also common with chronic inflammation.
- Pain and Discomfort: Inflammatory conditions such as arthritis and inflammatory bowel disease can cause persistent pain, discomfort, and reduced mobility.
Mental Health:
- Neuroinflammation: Inflammation in the brain, known as neuroinflammation, has been implicated in the pathophysiology of various mental health disorders, including depression, anxiety, schizophrenia, and cognitive decline.
- Neurotransmitter Imbalance: Inflammatory cytokines can disrupt neurotransmitter balance and function in the brain, affecting mood, cognition, and behavior.
- Stress Response: Chronic inflammation can activate the body’s stress response system, leading to increased production of stress hormones like cortisol, which can further exacerbate inflammation and contribute to mental health problems.
Weight Management:
- Metabolic Dysfunction: Inflammation is closely linked to metabolic dysfunction, insulin resistance, and obesity. Chronic low-grade inflammation can interfere with hormone-signaling pathways involved in appetite regulation, energy balance, and metabolism.
- Fat Accumulation: Inflammatory cytokines can promote the accumulation of visceral fat, which is associated with an increased risk of metabolic syndrome, type 2 diabetes, and cardiovascular disease.
- Leptin Resistance: Inflammation can impair the function of leptin, a hormone that helps regulate appetite and energy expenditure. Leptin resistance can disrupt satiety signals, leading to overeating and weight gain.
One of the easiest ways to reduce inflammation in the body is to avoid consuming inflammatory foods. This is especially true if you’re already experiencing the health and weight issues mentioned above.
TOP 10 FOODS THAT CAUSE INFLAMMATION
Processed Foods: Foods high in sugar, refined carbohydrates, and unhealthy fats, such as those found in fast food, processed snacks, and sugary beverages, can promote inflammation. The combination of refined sugars/carbs and unhealthy fats is the most inflammatory combination of nutrients possible. Refined sugars can lead to spikes in blood sugar levels, triggering an inflammatory response in the body. Unhealthy fats, such as trans fats and saturated fats, found in processed foods like fast food and snacks, can increase inflammation and raise the risk of chronic diseases like heart disease.
Trans Fats: Trans fats are found in many processed and fried foods, such as margarine, shortening, and commercially baked goods. They can increase inflammation and raise the risk of heart disease. Trans fats have been shown to promote inflammation by increasing levels of pro-inflammatory cytokines and oxidative stress in the body. They can also raise levels of “bad” LDL cholesterol and lower levels of “good” HDL cholesterol, increasing the risk of heart disease and other inflammatory conditions.
Sugary Drinks: Beverages high in added sugars, such as soda, energy drinks, and sweetened fruit juices, can contribute to inflammation and other health issues when consumed in excess. The high sugar content in these drinks can lead to spikes in blood sugar levels and insulin resistance, promoting inflammation and increasing the risk of chronic diseases like type 2 diabetes and obesity. Additionally, sugary drinks often lack essential nutrients and may displace healthier beverage choices, further contributing to inflammation and poor health outcomes.
Processed Meats: High intake of certain meats and processed meats like bacon, sausage, and deli meats has been linked to inflammation and an increased risk of chronic diseases like heart disease and cancer. Processed meats contain harmful additives like nitrates and nitrites, which can promote inflammation and oxidative stress in the body. Additionally, the high levels of saturated fats and advanced glycation end products (AGEs) found in red and processed meats can contribute to inflammation and insulin resistance, increasing the risk of metabolic disorders and inflammatory conditions.
Refined Grains/Carbs: Foods made with refined grains, such as white bread, white rice, and pasta, can spike blood sugar levels and promote inflammation when consumed regularly. Refined carbohydrates have a high glycemic index, meaning they cause rapid increases in blood sugar and insulin levels, leading to inflammation and insulin resistance over time. Additionally, refined grains lack essential nutrients like fiber, vitamins, and minerals, further contributing to inflammation and poor health outcomes.
Alcohol: Excessive alcohol consumption can lead to inflammation in the body, particularly in the liver. Alcohol is metabolized by the liver, where it can generate reactive oxygen species (ROS) and induce oxidative stress, leading to tissue damage and inflammation. Chronic alcohol abuse is associated with liver inflammation (alcoholic hepatitis), gastrointestinal inflammation, and systemic inflammation, increasing the risk of liver disease, digestive disorders, and other inflammatory conditions.
Artificial Additives: Some additives found in processed foods, such as artificial sweeteners, preservatives, and colorings, can cause inflammation. Many of these artificial additives are created by chemicals that are perceived as harmful by the immune system, triggering an inflammatory response as the body attempts to defend itself. Artificial sweeteners, preservatives, and colorings found in processed foods can trigger inflammation by disrupting immune function and promoting oxidative stress, too.
Vegetable Oils: Certain vegetable oils, such as soybean oil, corn oil, and sunflower oil, are high in omega-6 fatty acids, which can promote inflammation when consumed in excess. These oils are commonly used in processed and fried foods, contributing to the high intake of omega-6 fatty acids in the Western diet. While omega-6 fatty acids are essential for health, an imbalance between omega-6 and omega-3 fatty acids can promote inflammation and increase the risk of chronic diseases like heart disease, diabetes, and obesity.

Dairy Products: Dairy inherently isn’t inflammatory. The relationship between dairy consumption and inflammation is complex and can vary from person to person. BUT some people may experience inflammation or digestive issues from consuming dairy products, particularly those with lactose intolerance or sensitivity to dairy proteins like casein. Lactose intolerance, a condition characterized by the inability to digest lactose (the sugar found in milk), can lead to gastrointestinal symptoms like bloating, gas, and diarrhea, which may trigger inflammation in the gut. Additionally, some individuals may have an immune reaction to dairy proteins like casein, leading to inflammation and other adverse reactions. If you already have GI inflammation, then you can become sensitive to dairy, which is why those with GI issues are typically asked to avoid it.
Other Chemicals: Pesticides and fertilizers, commonly used in conventional agriculture to enhance crop yields and protect against pests and diseases, can contribute to inflammation in several ways. Some pesticides have been shown to disrupt normal physiological processes in the body, such as hormone regulation and immune function, which can trigger inflammatory responses. Additionally, certain pesticides are known to induce oxidative stress by generating reactive oxygen species (ROS) within cells, which can damage cellular structures and promote inflammation. Exposure to pesticides and fertilizers can disrupt the balance of gut microbiota, leading to dysbiosis and increased intestinal permeability, allowing toxins and inflammatory molecules to enter the bloodstream and provoke systemic inflammation.
Reducing these foods can help reduce inflammation quickly.
Other foods and drinks that can cause inflammation are things that you’re allergic, intolerant, or sensitive, too. These consumables are unique to you and vary from person to person. The only way to pinpoint what these are is to take a food allergy and/or sensitivity test.
Please note there are lots of different ways to test for allergies and intolerances. If you’ve already talked to your allergist or immunologist, I recommend functional lab testing to help pinpoint your unique food sensitivities, intolerances, allergies, and autoimmune reactions. For more information about functional labs check this out.
Those are the most common foods that cause inflammation. There are other things – that are NOT food – that can cause inflammation, too. Here’s a complete list of all things (other than food) that cause inflammation.
After cutting out the inflammatory foods above, make sure you’re reducing exposure to these other common causes on inflammation, too.
