Does sodium benzoate have any negative health effects?
Sodium benzoate is found in many soft drinks. It is not terrible for you, though there are soft negative side effects that you may experience. Sodium benzoate reduces the amount of potassium in your body. Also, it can cause recurring urticaria (rash), asthma, and eczema. Overall, it is not terrible for you, but it is good to consume in moderation. More and more facts come out each day about some negative aspects of soda, so I would recommend seriously cutting back on your consumption of soda. Sources: http://www.ionizers.org/soft-drinks.
