This 21-Day Anti-Inflammatory Diet Is the Exact Post-Holiday Reset Your Body Needs

Perhaps you also feel like you had too much to eat and drink during the holidays. A few weeks of going off the grid won't hurt, and food is more than fuel—it's part of our culture and social gatherings. However, getting back to eating nourishing foods can help you feel like your healthiest self. Following an anti-inflammatory meal plan can simplify choosing foods and kickstart healthy habits.

Why anti-inflammatory meals? Let's back up. While inflammation typically has a bad connotation, it's a natural process that helps us survive.

"Inflammation is your body's natural response to protect itself against harm," says Dr. Chris Mohr, Ph.D., RD, a fitness and nutrition advisor for Barbend. "It activates the immune system when there’s an injury or infection. This helps signal the body to repair damaged tissue and fight harmful viruses and bacteria."

Short-lived inflammation is healthy and necessary. However, there's such a thing as too much of a good thing.

"Chronic inflammation, which may come from ongoing factors like obesity, smoking or autoimmune disorders and is not healthy or desired," Dr. Mohr says.

A 2019 Nature Medicine review linked chronic inflammation with an increased risk for diabetes, heart disease and arthritis.

Diet is one way to reduce chronic inflammation and boost your health. Registered dietitians dished on what to eat, including a whole 21-day anti-inflammatory diet plan.

What Is the Anti-Inflammatory Diet Plan?

The basics: "An anti-inflammatory diet is one that minimizes or eliminates foods that exacerbate inflammation, which in turn may raise the risk of chronic disease," says Maria Keaveney, RD, a registered dietitian at Fay.

Annette Snyder, MS, RD, CSOWM, LD, a registered dietitian with Top Nutrition Coaching, says the anti-inflammatory diet plan closely mirrors the Mediterranean diet.

"Each day includes a variety of colorful plant foods, fiber and healthy fats," Snyder says. "What you won’t find: excess amounts of foods that can make inflammation worse, like refined grains, added sugars and highly-processed meats."

A 2021 Biomedicines review found that following an anti-inflammatory diet plan could increase a person's intake of healthy compounds, decrease disease risk and promote healthy aging.

  • Fruits

  • Vegetables

  • Healthy fats

  • Plant-based proteins

  • Fish

  • Lean meats

  • Nuts and seeds

Some examples of foods you'll find on an anti-inflammatory meal plan include:
