Yes. A huge proportion of your immune system is actually in your GI tract.^[7]

We’re still in the early days of understanding how your gut bacteria interact with your body’s immune system. Early research suggests that your gut bacteria help keep microorganisms in balance and remove environmental toxins from the body.^{[8] [9]}

Prebiotics feed probiotics, the good bacteria in your gut. Getting more prebiotics in your diet helps support healthy digestion, nutrient absorption and immunity — plus, it keeps you regular.^{[10] [11]}

You can get prebiotics in fiber-rich foods like asparagus, broccoli, onion, green bananas and chicory. When it’s hard to get enough fiber-rich foods, take a prebiotic supplement like Bulletproof InnerFuel.

Exercise can help support your immunity in the following ways:^[12]

• Physical activity can flush bacteria out of your airways
• Exercise stimulates your antibodies and white blood cells to circulate more rapidly, which may help your immune system detect illness earlier
• Raising your core body temperature during exercise can help prevent bacteria from growing
• Exercise is a great way to manage stress, and stress is associated with a greater risk of illness.

There are tons of reasons you might get sick. It might be your diet, environment, stress, lack of sleep, age, genetics or even an underlying health condition. If getting sick feels like a habit, talk to your doctor. Set yourself up for success with a strong foundation:

• Physical activity can flush bacteria out of your airways.
• Exercise stimulates your antibodies and white blood cells to circulate more rapidly, which may help your immune system detect illness earlier.
• Move more often
• Get adequate sleep
• Stay hydrated
• Minimize stress

• Nuts and seeds: Rich sources of vitamin E, a fat-soluble vitamin that is crucial for immune function

• Colorful foods like carrots, sweet potatoes and squash: High in compounds called carotenoids, which your body turns into immune-boosting vitamin A
