Your immune system becomes activated when your body recognizes anything foreign—such as an invading microbe, plant pollen, or chemical. This triggers a process called inflammation. Intermittent bouts of inflammation directed at truly threatening invaders protect your health.
However, sometimes inflammation persists, day in and day out, even when you are not threatened by a foreign invader. That’s when inflammation can become your enemy. Many major diseases that plague us—including cancer, heart disease, diabetes, arthritis, depression, and Alzheimer’s—have been linked to chronic inflammation.
Foods that cause inflammation
- refined carbohydrates, such as white bread and pastries
- French fries and other fried foods
- soda and other sugar-sweetened beverages
- red meat (burgers, steaks) and processed meat (hot dogs, sausage)
- margarine, shortening, and lard
Not surprisingly, the same foods on an inflammation diet are generally considered bad for our health, including sodas and refined carbohydrates, as well as red meat and processed meats.
Some of the foods that have been associated with an increased risk for chronic diseases such as type 2 diabetes and heart disease are also associated with excess inflammation. It’s not surprising, since inflammation is an important underlying mechanism for the development of these diseases.
Unhealthy foods also contribute to weight gain, which is itself a risk factor for inflammation. Yet in several studies, even after researchers took obesity into account, the link between foods and inflammation remained, which suggests weight gain isn’t the sole driver.
Anti-inflammatory foods
An anti-inflammatory diet should include these foods:
- tomatoes
- olive oil
- green leafy vegetables, such as spinach, kale, and collards
- nuts like almonds and walnuts
- fatty fish like salmon, mackerel, tuna, and sardines
- fruits such as strawberries, blueberries, cherries, and oranges
On the flip side are beverages and foods that reduce inflammation, and with it, chronic disease. In particular, fruits and vegetables such as blueberries, apples, and leafy greens are high in natural antioxidants and polyphenols—protective compounds found in plants.
Studies have also associated nuts with reduced markers of inflammation and a lower risk of cardiovascular disease and diabetes. Coffee, which contains polyphenols and other anti-inflammatory compounds, may protect against inflammation, as well.
In addition to lowering inflammation, a more natural, less processed diet can have noticeable effects on your physical and emotional health. “A healthy diet is beneficial not only for reducing the risk of chronic diseases but also for improving mood and overall quality of life.
