What you eat plays a huge role in your body's inflammation. According to Harvard Health, inflammation occurs when white blood cells flood a particular part of your body that needs protection from infection, damage, or unfamiliar substances. Smoking or building up fat from eating inflammatory foods causes your immune system to think your body is under attack, and if your body is constantly in this state it can lead to chronic inflammation, which can lead to heart attacks and strokes.

While this condition sounds terrifying, it can be preventable. By focusing on your diet and how you treat your body, you can stop inflammation in its tracks. Red meat and soda can cause greater chronic inflammation, but the nutrients found in tomatoes, olive oil, fatty fish, and nuts can all help prevent and reverse the effects of inflammation. The best way to tackle this issue starts at the doors of Costco when you go on your next grocery run.

You can take the first step towards beating inflammation by making sure you stock your spice cabinet up with turmeric.

"[This product] contains the compound curcumin from turmeric, which researchers have shown reduces inflammation in humans," says Bryan Quoc Le, Ph.D. and author of 150 Food Science Questions Answered. "Curcumin works by binding to a protein in our cells that activates a series of cellular signals to the nucleus. These signals trigger the cellular machinery to release a number of antioxidant and anti-inflammatory defenses and enzymes."

"Curcumin is a relatively potent anti-inflammatory molecule and several clinical trials demonstrate that the compound has the potential to reduce chronic inflammation from several conditions," he continues.

"One of my favorite Costco finds are these That's It fruit bars," says Marissa Meshulam, MS, RD, CDN, and founder of MPM Nutrition. "Unlike many bars that are filled with inflammatory ingredients, these bars are made only with real fruit, which provides a ton of antioxidants that work to keep our cells healthy and fight inflammation. They are a perfect convenience item for days when you haven't made it to the store yet but want to add some fruit to your snack or lunch bag."

"They contain no added sugar or inflammatory oils," adds Meshulam. "Instead, they rely on the natural sweetness from fruit to taste great!"

Young, Ph.D., RDN, and a member of our medical expert board. "I love the stir fry blend which can help round out your meal. The veggies are antioxidant-rich—particularly high in vitamin C which can fight inflammation."

Kirkland Mixed Nuts—Unsalted

A variety of nuts can help you get to any health goal, and these Costco snacks keep you feeling great.

"Nuts are rich in heart-healthy fats which may help to fight inflammation while also protecting your heart and keeping blood sugar steady," says Young. "I prefer the unsalted varieties. Tip—because the calories in nuts add up quickly, scoop out a 1 oz portion (around a handful) and put it in a dish instead of eating from the container."
