Inflammation is a natural part of the body’s defense system. When you get injured or fight off an infection, inflammation helps your body heal.

But when inflammation becomes chronic, it can quietly contribute to a range of health problems, including heart disease, diabetes, arthritis, digestive disorders, and even cognitive decline.

The good news? What you eat may play a major role in either fueling or fighting inflammation.

While there isn’t one official “anti-inflammatory diet,” health experts generally agree on a simple principle: eat more whole foods and fewer heavily processed ones.

Here’s what that looks like in practice.

The Foods Most Experts Recommend Avoiding

One of the biggest drivers of inflammation appears to be ultra-processed foods.

These are foods that often come in boxes, bags, or packages and contain long ingredient lists filled with additives, preservatives, refined ingredients, and added sugars.

Examples include:

  • Sugary breakfast cereals
  • Packaged baked goods
  • Candy
  • Microwave meals
  • Chicken nuggets
  • Processed meats
  • Hot dogs
  • Instant soups
  • Sweetened beverages
  • Packaged sauces and dressings

Many of these foods contain ingredients linked to inflammation, including excessive sodium, added sugars, and unhealthy fats.

Research also suggests that highly processed foods may negatively affect gut health, which plays an important role in regulating inflammation throughout the body.

Why Added Sugar Can Be a Problem

Added sugars are often considered one of the biggest dietary contributors to inflammation.

They’re found in obvious sources like:

  • Soda
  • Candy
  • Cookies
  • Cakes

But they’re also hidden in many foods people don’t expect, including:

  • Flavored yogurts
  • Salad dressings
  • Pasta sauces
  • Granola bars

Consuming too much added sugar may contribute to blood sugar spikes and inflammatory responses throughout the body.

What About Artificial Sweeteners?

Many people replace sugar with low-calorie sweeteners.

However, some research suggests that certain artificial sweeteners may also affect gut bacteria and inflammatory pathways.

While scientists continue studying these effects, many nutrition experts recommend focusing on naturally whole foods rather than relying heavily on either sugar or artificial sweeteners.

Refined Carbohydrates May Also Contribute

Foods made with refined flour are another common source of concern.

Examples include:

  • White bread
  • White pasta
  • White rice
  • Crackers
  • Pastries

Because these foods are processed and stripped of much of their fiber, they can cause rapid increases in blood sugar levels, which may promote inflammation over time.

Foods That May Help Fight Inflammation

Fortunately, many foods contain nutrients and compounds associated with lower levels of inflammation.

The foundation of an anti-inflammatory eating pattern typically includes:

Fruits and Vegetables

Brightly colored produce contains antioxidants that help protect cells from damage.

Some excellent choices include:

  • Berries
  • Tomatoes
  • Carrots
  • Broccoli
  • Bell peppers
  • Leafy greens
  • Squash

The more color on your plate, the better.

Whole Grains

Unlike refined grains, whole grains contain fiber and beneficial nutrients that support digestive and overall health.

Good options include:

  • Oats
  • Barley
  • Brown rice
  • Quinoa
  • Whole grain breads

Legumes

Beans, lentils, and chickpeas provide fiber, protein, and a variety of beneficial plant compounds that support overall health.

Healthy Fats

Certain fats may help support a healthier inflammatory balance.

Examples include:

  • Olive oil
  • Avocados
  • Walnuts
  • Almonds
  • Pecans
  • Pumpkin seeds
  • Flaxseeds

Omega-3-Rich Foods

Omega-3 fatty acids are among the most studied nutrients for their potential anti-inflammatory benefits.

Foods rich in omega-3s include:

  • Salmon
  • Sardines
  • Mackerel
  • Tuna
  • Flaxseeds
  • Walnuts

Herbs and Spices

Many herbs and spices contain plant compounds that researchers continue to investigate for their potential health benefits.

Popular choices include:

  • Turmeric
  • Ginger
  • Cinnamon
  • Cayenne pepper

How to Make the Transition Easier

Many people fail when they attempt to completely overhaul their diet overnight.

Instead, focus on gradual changes.

A simple guideline is this:

Eat more foods that come from the ground and fewer foods that come from a package.

For example:

Breakfast

  • Oatmeal topped with berries
  • Fruit smoothie with protein and greens

Lunch

  • Large salad with mixed vegetables
  • Beans, seeds, and a lean protein source

Dinner

  • Fish, poultry, or legumes
  • Colorful vegetables
  • Whole grains on the side

Dessert

  • Fresh fruit instead of heavily processed sweets

The Bottom Line

An anti-inflammatory diet doesn’t require strict rules, expensive supplements, or complicated meal plans.

In many cases, it’s simply a return to basics.

By focusing on whole foods, colorful fruits and vegetables, healthy fats, and minimally processed ingredients, you may help support your body’s natural defenses while reducing exposure to foods associated with chronic inflammation.

And perhaps the simplest rule of all?

If your plate is colorful, varied, and made mostly from real foods, you’re probably moving in the right direction.
