• Eating an anti-inflammatory lunch every day for a week helped a dietitian reduce brain fog. 
  • She also felt more energized, mentally sharper and better focused.
  • To try it, build your meal around veggies, whole grains, beans, healthy fats and lean protein.

As a registered dietitian who works from home, my days are packed with juggling my workload while attempting to sneak in a workout, drink enough water, and generally do all the things we are “supposed” to do to support our health. While I’m passionate about nutrition, the daily realities of work don’t allow for much time to spend prepping elaborate lunches. Still, I know firsthand how much our food choices impact not only our bodies but also our energy, focus and long-term health.

Lately, I’ve been reflecting on how inflammation ties into all of this—how it’s not just triggered by illness but also by the stressors and habits we face every day. So, what is inflammation, and why does it matter? Christina Chu, M.S., RD, puts it well: “Inflammation is, in simple terms, damage to the body.” 

It can be triggered by certain medical conditions, and it can also be caused by the foods you do–or don’t–eat, she says. “Consuming a diet rich in anti-inflammatory foods can protect the body from everyday damage and ultimately prevent diseases,” she explains.

With that in mind, and knowing I needed quick, realistic options, I challenged myself to eat an anti-inflammatory lunch every day for a week, just to see what would happen. I expected to feel a little more spring in my step during this journey. But what I didn’t expect was that my typical afternoon brain fog almost completely disappeared.

The Surprising Benefit I Noticed: A Clearer Mind

Around 3 p.m. each day, a familiar mental haze used to settle in. My focus would drift, my productivity would plummet, and my ability to form a coherent thought felt like wading through mud. I’d often reach for another coffee or a sugary snack to power through, but it was always a temporary fix.

After a few days of my anti-inflammatory lunch experiment, I realized my afternoons felt different. The usual slump was replaced with a steady, sustained energy. My mind felt sharper, and I was able to stay focused on tasks without feeling that familiar mental strain. It turns out this wasn’t just a coincidence. The foods I was eating were directly impacting my cognitive function.

Many of the nutrient-dense ingredients in my new lunch choices were rich in antioxidants and polyphenols. These compounds help combat oxidative stress, a key driver of inflammation throughout the body and the brain. By reducing this inflammation, I was essentially creating a better environment for my brain to function optimally. The high-fiber content of my lunch also helped stabilize my blood sugar levels, preventing the dramatic spikes and crashes that often lead to energy slumps and mental fatigue.,

What I Ate for Lunch

“The anti-inflammatory diet is really just simple whole foods. Think about counting colors instead of calories and you’re half way there,” says Anne Murray, M.S., RD. And she’s right. Committing to an anti-inflammatory lunch was easier than I thought. I prepped a few key recipes at the start of the week, which made grabbing a healthy meal simple and stress-free.

To keep things easy, I made these three dishes on repeat, and I loved every bite. Here’s a look at what I ate:

No-Cook White Bean & Spinach Caprese Salad

This was the easiest meal of the week. I just tossed all the ingredients together for a fresh, satisfying lunch. The white beans provided plant-based protein and fiber, while the spinach and tomatoes offered a powerful dose of antioxidants. The extra-virgin olive oil in the dressing gave me healthy monounsaturated fats and oleocanthal, a compound with potent anti-inflammatory properties.

Kale & Sweet Potato Salad with Chicken

A hearty salad, like this, was perfect for days when I needed something more substantial. The sweet potatoes are a source of beta-carotene, an antioxidant that supports overall health and helps combat inflammation., Kale, a nutrient powerhouse that contains vitamins A, C and K, is known for its anti-inflammatory properties as well. The chicken provided lean protein to keep me fueled, while the almonds added healthy fats, a satisfying crunch, and additional inflammation-taming antioxidants. The tahini-based dressing brought in even more healthy fats and nutrients.

High-Protein Butternut Squash & Lentil Soup

This warm, comforting soup was a perfect meal for a cooler day. Butternut squash is rich in antioxidants like beta-carotene and vitamins A and C. The lentils are a source of fiber and plant-based protein, which helps with satiety and blood sugar management. To top it all off, a dollop of non-fat plain (Greek style) yogurt delivered additional blood-sugar-leveling protein.

Tips to Eat an Anti-Inflammatory Lunch

Incorporating more anti-inflammatory foods into your day may sound daunting, but it’s actually much easier than you might expect. Here are a few simple tips to get started: 

  • Include healthy fats: Don’t be afraid of fat! Incorporate sources of omega-3s, such as salmon, and monounsaturated fats like avocados, olive oil and nuts. These fats are essential for fighting inflammation.,
  • Limit added sugars and refined carbs: Foods high in added sugar and refined carbohydrates (like white bread, pastries and sugary drinks) can promote inflammation. Try swapping them for whole-grain alternatives and naturally sweet fruits.
  • Embrace herbs and spices: Turmeric, ginger and cardamom are just a few of the many spices with powerful anti-inflammatory properties. Be generous with them in your cooking to boost flavor and tackle inflammation.
  • Eat the rainbow: Colorful fruits and vegetables provide a wide array of vitamins, minerals and antioxidants. Aiming to include a variety of colors on your plate ensures you’re getting a broad range of protective compounds.

Our Expert Take

“Eating an intentional anti-inflammatory lunch is one of the best ways to make a small change into your daily routine,” says Murray. And I found the experience to be transformative. This one-week experiment was a powerful reminder of how directly our food choices impact how we feel, not just physically but mentally. By focusing on one meal, I was able to see a tangible benefit in my daily life without feeling overwhelmed by completely overhauling my meals. In my case, the habit is likely to stick! The disappearance of my afternoon brain fog gave me the motivation I needed to continue making these small, positive changes. Give it a try. You may never go back to the same old lunch again.
