Get Your Greens: 3 Immune-Boosting Ingredients That Make Superfood Smoothies

The combination of training and seasonal changes can put a lot of stress on our body. While quality sleep, stress management, and exercise all play a significant role in keeping our body healthy, quality nutrition is no doubt one of the most important ways we can support our immune system and be proactive with our health. 

Quality nutrition means consuming nutrient-dense whole foods while avoiding pre-packaged processed forms, as highlighted by F45 Sport Nutritionist Kim Bowman. Whole food sources like spinach, broccoli, and avocados not only contain dietary fiber—which is key for gut health—but they also provide core vitamins and minerals to reduce inflammation and fight infection in the body. Processed foods, on the other hand, are stripped of their dietary fiber and essential immune-boosting micronutrients during the manufacturing process. 

When it comes to immune-boosting superfoods, green fruits, veggies, and tea not only pack rich sources of immune-supporting antioxidants, but make key ingredients in these tasty F45 Challenge superfood smoothies.

It’s a no-brainer that this green leafy vegetable is at the top of the list when it comes to immune-supporting superfoods. Spinach packs a ton of nutrients—including iron, magnesium, folate, and vitamin C—that play key roles in helping the immune system ward off disease and infection. This green superfood also contains a number of antioxidants, including beta-carotene, which is a precursor to another immune powerhouse, vitamin A (retinol). The phytonutrients (natural chemicals) found in raw spinach have anti-inflammatory properties and help to detoxify the body as well. We recommend adding this spinach-packed Banana Green Smoothie to your morning routine, as it takes less than 5 minutes to prepare and provides your body with plenty of energizing vitamins and minerals!

Matcha is made from green tea leaves that have been ground into a fine powder, and is one of richest sources of antioxidants out there. More specifically, it contains a class of antioxidants known as catechins, which play a key role in reducing the formation of ‘free radicals’ in the body. This protects the cells from becoming damaged by inflammation, which is essential in allowing the immune to do its job and function optimally. If this weren’t enough, matcha is also a natural detoxifier due to its chlorophyll content, which helps to rid the body of harmful toxins and heavy metals. Adding this Matcha Banana Protein Smoothie to your morning is the perfect way to give your body the nutrients it needs to stay energized, focused, and healthy during Challenge.
