Boosting your Immune System

As we prepare to reengage with the outside world again, a topic that is top-of-mind is immunity. What steps can we take to build a stronger immune system through food?

One of my favorite ways to think about how to boost your immunity is through a compound in food called phytonutrients. What are they and what do they help us do?

Phytonutrients have a prolific number of positive health benefits. They assist in removing toxins, supporting immunity, and improving heart health. Phytonutrient compounds are part of what gives food it’s color. We commonly group these powerful food compounds into 5 color categories: green, yellow/orange, red, blue/purple, and white/brown.

A great baseline goal which can give your body a good number of phytonutrients is to eat a food from each color every day. Here are some examples of foods to pick from. Remember our best sources are typically fruits and veggies, however other natural sources include whole grains, beans and legumes, nuts, and seeds.

Green:

– Spinach, kale, arugula, chard, green bell peppers, chives, asparagus, limes, peas, avocado, broccoli, zucchini

Yellow/orange:

– Banana, orange, yellow/orange bell pepper, yellow squash, carrots, pumpkin, squash, cantaloupe, mango, sweet potato, corn

Red:

– Strawberries, raspberries, red bell pepper, tomato, grapefruit, cherries, rhubarb, watermelon, beans, beets

Blue and Purple:

– Blueberries, blackberries, plums, eggplant, grapes, figs, purple potatoes, raisins, black rice, purple kale

White and Brown:

– Cauliflower, jicama, mushrooms, garlic, onion, coconut, ginger, apples, seeds, nuts, legumes, pears

PRO Tips: add a variety of color to stir-fry meals, casseroles, or shakes/smoothies! Tea can also be a great way to incorporate color easily.
