Anti-inflammatory Rainbow: Blue and Purple Foods
Anti-Inflammatory Food and Colors
The foods that help fight inflammation come in all different colors. Each color has special properties that help fight inflammation and provide a myriad of other benefits to our body. These special properties are often referred to as the large category of “phytonutrients” which is basically a fancy word for plant nutrients. There are over 100,000 phytonutrients in the plants we eat! You can learn more about phytonutrients here. The anti-inflammatory nutrients make up hundreds of those phytonutrients. The color of a plant tells us some things about which phytonurients and which anti-inflammatory nutrients that plant contains. It’s vitally important that we get a variety of colors in our diet to make sure we are getting in the wide variety of phytonutrients and anti-inflammatory compounds that we need for optimal health. This post is all about the blue and purple foods and how they benefit our health.

ANTI-INFLAMMATORY BLUE AND PURPLE FOODS COMPOUNDS
Blue and purple foods provide us an array of hard to pronounce, but no less beneficial, phytonutrient compounds. Anthocyanidins,
hydroxystilbenes, procyanidins, pterostilbene, and the familiar resveratrol are all anti-inflammatory compounds found in blue and purple foods. Let’s review some of the specific benefits of these phytonutrients!
Found in blueberries and black grapes, this phytonutrient may help ward off cancer, keep cholesterol under control, and preserve brain function. Pteorstilbene found in blue and purple foods has been shown to have an anti-cancer effect by reducing the cell proliferation in breast cancer. The anti-oxidant activity in blueberries has been shown to be protective against atherosclerosis (plaque build up in arteries). Gastrointestinal cancers in the stomach, colon, and esophagus have been shown to have positive change related to high intakes of this phytonutrient as well. There are studies to support blue and purple foods for type 2 diabetes management as well due to pteorstilbene. This anti-oxidant may also slow down neurodegeneration.

Red wine is the most familiar resveratrol containing food item. However, its also high in black grapes and blueberries. This phytonutrient has high anti-inflammatory properties and slows down the aging process.
