For allergy sufferers, spring can mean stuffy noses and runny eyes.

Surprisingly, doctors say your stomach is what you should treat first.

Experts say 80 percent of your immune system lives in your GI tract. With that in mind, keeping your diet in check can balance an entire system.

Friendly foods for sufferers to eat include fruits and vegetables, peppers, broccoli and kale. Those foods have natural antihistamines and anti-inflammatory properties  which are key ingredients in over-the-counter allergy medications.

Meanwhile, dairy is one thing you should try to avoid because a primary protein created through the pasteurization process is one the immune system tries to fight. That means it could make you more susceptible to allergies.
