Inflammation sometimes gets a bad rap, but it is an important part of your body’s defense. It helps you fight off infections and heal from injuries.
The main concern is chronic inflammation. This type of low-level inflammation can linger in your body for a long time. It’s linked to heart disease, type 2 diabetes, and other illnesses that often develop as we age.
Your daily habits matter. Regular exercise, good sleep, avoiding tobacco, managing stress, and eating a healthy diet all make a difference.
The short answer is yes. Research suggests that eating a healthy plant-based diet can help reduce chronic inflammation. Diets centered on plant foods can lower C-reactive protein (CRP), a common sign of inflammation. But the quality of what you eat is important. Eating mostly whole plant foods is different from following a vegan diet that includes lots of refined grains, sweets, and processed foods.
What is Chronic Inflammation?
Acute (short-term) inflammation is a normal response. If you cut your finger or get an infection, your immune system goes to work and then settles down once the problem has passed.
Chronic inflammation is different. Your immune system can stay active at a low level for a long time. This kind of inflammation can be influenced by many factors, including genetics, aging, diet, and other lifestyle habits.
Diet isn’t the only factor, but it is one thing we can control.
What Do the Studies Show About Inflammation?
A 2026 review combined seven randomized clinical trials involving 541 people. Those eating diets centered on plant foods had a greater reduction in CRP than those eating omnivorous diets.
Across the studies, CRP decreased by about 1.13 mg/L more in the plant-based groups than in the omnivorous groups. Even after researchers removed studies that included exercise programs, the reduction remained significant.
The studies varied a lot, so the authors said more research is needed. Still, the overall results suggest that eating plant-based can help lower CRP, a marker of inflammation.
See my Top 15 anti-inflammatory recipes in this article: “15 Plant-Based Recipes to Soothe Inflammation.”
The Quality of Your Plant-Based Diet Matters
Just calling a diet “plant-based” does not mean it is healthy.
A vegan diet can still include refined grains, sweets, sugary drinks, chips, and other processed foods.
A study of nearly 28,000 U.S. adults found that people who ate more whole, nutritious plant foods had less systemic inflammation. In contrast, people whose plant-based diets included more refined grains, sugary foods and drinks, and other highly processed foods tended to have higher levels of inflammation.
Because this was an observational study, it can’t prove cause and effect. Still, it reinforces an important point: what you eat instead of animal foods matters.
That’s why I focus on a whole-food, plant-based diet that includes vegetables, fruits, beans, lentils, whole grains, nuts, and seeds.

Why Whole Plant Foods Can Help
No single food or nutrient by itself gives a healthy diet its anti-inflammatory benefits.
Whole plant foods provide a mix of fiber, vitamins, minerals, healthy fats, and natural plant compounds called phytochemicals. These nutrients work together to support health.
Beans, lentils, vegetables, fruits, and whole grains give you fiber that supports a healthy gut. Colorful fruits and vegetables contain compounds like carotenoids and polyphenols. Nuts and seeds provide healthy fats, and foods such as flaxseed, chia seeds, and walnuts supply the plant-based omega-3 fat ALA.
You don’t need to remember every nutrient. Eating a variety of whole plant foods is an easy way to get them all.
Here is a helpful tip: carotenoids are fat-soluble, so eating colorful vegetables with some whole-food fat like walnuts, seeds, tahini, or avocado can help your body absorb them.

Whole Plant Foods to Eat Regularly
Instead of searching for a single “anti-inflammatory” food, try to eat a variety of these foods:
- Leafy greens and cruciferous vegetables
- Colorful vegetables such as carrots, tomatoes, peppers, and squash
- Berries, cherries, citrus, apples, and other fruits
- Beans, lentils, peas, and soy foods
- Whole grains such as oats, barley, brown rice, farro, and quinoa
- Walnuts, flaxseed, chia seeds, and other nuts and seeds
- Herbs and spices such as turmeric, ginger, cinnamon, and garlic
The goal is not to eat a lot of just one food. What matters most is variety.
Keep It Simple
You don’t need special “anti-inflammatory meals.”
Start with vegetables, add beans or lentils, and include a whole grain or starchy vegetable. Then add a small amount of nuts, seeds, avocado, or another whole-food fat.
For example, you could have steel-cut oats with blueberries, ground flaxseed, and walnuts. Or try brown rice and black beans with vegetables, greens, salsa, and avocado. Another option is a salad topped with chickpeas, quinoa, colorful vegetables, and a tahini-lemon dressing.
One of my favorite dishes is Mulligatawny Soup, made with red lentils, lots of vegetables, fresh ginger, and turmeric. It consistently gets great reviews.

The Bottom Line
A whole-food, plant-based diet can help reduce chronic inflammation. You don’t need to focus on individual “superfoods.” Instead, build your meals around a mix of vegetables, fruits, beans, whole grains, nuts, and seeds.
Remember, food is only part of the picture. Regular movement, adequate sleep, avoiding smoking, and finding ways to manage stress also support long-term health.

You don’t have to change everything at once. Start with a few simple changes and look for easy ways to add more plant foods to your meals.
Smoothies are a great way to make sure you’re getting lots of inflammation-reducing fruits and vegetables. Smoothies, such as my V-8, Pumpkin Pie, Chocolate Cherry, Mint Chocolate, Heart Healthy, Healing Turmeric, and a Green Berry smoothie
Of course, you can’t live on smoothies alone! Good news – all the recipes on my Plantbasedcooking.com site contain anti-inflammatory plant foods, so you can’t go wrong!

Would like to know more, I’ve been battlering with neuromyelitis for 5 yr. and really need help
I’m so sorry to hear that you’ve been suffering. I haven’t heard of neuromyelitis but I see it’s an inflammatory condition. Of course, I’m not a doctor, but because of the evidence that a plant-based diet can reduce inflammation, I think it’s worth a try if you haven’t already. I’d also check into meditation and visualization to try to calm your immune system down and reduce stress. Here’s an article that discusses this. Check out my “Start Here” page, also, if you’re just getting started for more information and let me know what you think.
..if its a plant, eat it if it COMES from a plant, don’t. That said, too much of anything is probably too many calories! I have been on plant based for 7 weeks, I’m not a big guy and was maybe 10-15+ over where I need to be. I lost 12 lbs, more energy, feel great, body fat % went down and I’m looking forward to next blood work to see if there’s any improvement there. It’s certainly a BIG TIME heart healthy way to go for men of a certain age 😉 and I cant believe how much I like the food….I’m doing no meat, no dairy, very little egg whites and some tuna/salmon!!
I agree, too many calories, in any diet, leads to weight gain. Congrats for switching to a plant-based diet. I’m so glad that you’re having great results and enjoying the food so much!! I love hearing positive results. Keep up the good work and check in again and let us know how it’s going.
I have Rheumatoid Arthritis, Diverticulitis, Malabsorbtion, and more. The medications don’t stop the pain, and have awful side effects: hair loss, paper thin skin, shut down my arsenals, …
I’ve read that gluten is terrible for autoimmune diseases, as are nightshades. I’m feeling like there’s nothing left to eat. Can anyone help?
Hey Sherri, I’m so sorry you’re suffering. If you’re eating a plant-based diet, that would be a good step and be sure to include the foods that are the most anti-inflammatory. Of course, I’m not a doctor, but I have read many testimonials about people getting better and healing by eating this way. It can seem like it’s limiting at first, but there are so many choices. Be sure to check out my list of tasty recipess on the site. Also, you will probably get more feedback on your question if you post in a Facebook group (you’d have to join the group). There are many that focus on a plant-based diet. Here’s one I belong to. You can search the group with keywords, like auto-immune, and relevant posts will come up. Also, check out Dr. Fuhrman’s post on the topic. What’s the most difficult part for you? I hope this helps!
Went vegan in January after my son told me to watch a video. Always was in shape but now more so. My mother in law had terrible arthritis and couldn’t close her fingers to make a fist. She stayed with us for 2 weeks and followed my diet. In 6 days – no joke – she was closing her fists. She couldn’t believe it. She’s been vegan for 3 weeks and won’t go back. Every day her health is getting better. Of meat, dairy and eggs – get rid of the dairy ASAP. It’s the absolute worst thing for inflammation and it’s so easy to do with many substitutions. If you like cereal or ice cream or sauces – you can buy / make them and not miss out all. Just try it for 2 weeks and you’ll see the difference. Stop complaining and just get on with it if you want to feel better. It’s so easy – just make
Wow, what a great testimonial for the power of a plant-based diet and thanks for your encouraging words. I can’t believe she had such great results in just 2 weeks. Anyone should be able to try it for at least that long.
Tomatoes and all peppers including bell peppers are veggies that cause inflammation. They are on the AIP avoid list along with other nightshade foods
I have heard that the nightshade vegetables including peppers and tomatoes have been implicated in inflammatory conditions, including arthritis because of the alkaloid, solanine. However, not everyone benefits from removing these from their diet and the arthritis foundation says, “It is anecdotal, and it certainly might be true for some people, but there are no scientific studies done to prove that they actually cause inflammation or make symptoms worse.” That said, I do believe that we’re all individual and it’s worth a try to eliminate these for some people with inflammatory conditions. Thanks for bringing that to my attention.
I really admire those people who go on a plant-based diet. Eating plant-based meals may be a good diet but I don’t think I can survive with it because I love to eat proteins in eggs and meat.
Hi and thanks for your comments and observation. I understand how eating meat and eggs are hard to give up after all they’ve probably been a part of your life forever. The problem is that they may not like you in the sense that they’re not optimal for health (or for the environment and the wellbeing of animals). The trick is to not think about what you’re giving up but to find plant-based proteins that you also enjoy…beautiful bean chilies, chickpea hummus, sweet and sour tofu. And, we generally need less protein than most people think. You can trend toward a more plant-based diet by substituting some of your meals, doing meatless Monday or go “Vegan Before 6,” like in Mark Bittman’s book. It’s not an all or nothing view at least for me because we’re all individuals and different. I hope that helps.
I am 80 years young, was told earlier this week that “you look to be about 62”. I have been a vegetarian for about 70 of those 80 years and am leaning more toward vegan as time goes on. I have no chronic health problems. I also raised 5 boys on the same program, all are in their 50’s now and to the extent they have maintained that diet, their health is good.
Hi Dee, what a great testament to the power of a plant-based diet! I’ve noticed over the years that people who look younger than their age are often vegetarians/vegans.
