What’s In My Food: Diet Coke Ingredients Explained


Reading the ingredient list on your food label and knowing what they are, are two different things. For example: Do you know what the ingredients BHT, partially hydrogenated soybean oil, blue 1, and phosphoric acid are? Well you should, since you are consuming them on a daily basis. One's use is banned in restaurants. Another is mined from the earth. And the Other two are made from petroleum.

Can you imagine what these ingredients are doing to your body? Well don't imagine. Know. Educate yourself. Read on to learn exactly what your food is made of, and what it’s doing to your health.


In all products, ingredients must be listed according to their relative weight. The listing of each ingredient is in a descending order of predominance.



Diet Coke’s ingredients are: Carbonated water, caramel color, aspartame, phosphoric acid, potassium benzoate (to protect taste), natural flavors, citric acid, caffeine.

1. Carbonated Water: Plain water into which carbon dioxide gas has been dissolved.

Health effects: Linked to tooth decay. May reduce fertility. Suspected teratogen (any agent that interferes with normal embryonic development).


2. Caramel Color: Brown food coloring and flavoring made by heating a sugar, usually corn syrup. May be processed with ammonia and sulfur to intensify color.

Health effects: May contain ammonium compounds. May affect stomach (gastrointestinal problems), liver, and cause hyperactivity. Caramel color produced with ammonia has been associated with blood toxicity in animals. Associated with reduced white cells and lymphocyte counts.


3. Aspartame: Artificial sweetener. Made from aspartic acid and phenylalanine.

Health effects: Studies link it to cancer in rats. May cause neurological and behavioral issues. Reported symptoms include irritability, headaches, insomnia, hyperactivity, seizures, memory loss, migraines, depression, vision problems, memory loss.

5. Potassium Benzoate: A preservative. Potassium salt of benzoic acid. Benzoic acid is synthesized commercially from toluene. Toluene is produced in the gasoline making process and the making of coke (carbon fuel produced by distillation of coal) from coal. Therefore, potassium benzoate is a petroleum or coal tar derivative.

Health effects: Asthma, hives, eczema. Caution advised if aspirin sensitive.

Benzene, a known cancer-causing agent, can form in soft drinks when sodium benzoate and ascorbic acid (vitamin c, commonly added to fortify soft drinks) are mixed.


6. Natural flavors: Any flavor not chemically derived. Obtained by physical processes from plants or animals. Made to provide flavor to a food rather than nutritional value. May contain MSG.

Health effects: Unknown.Different foods use different natural flavors and processes. Naturally derived ingredients may be altered, rendered unsafe. It should be noted that the use of the word “natural flavors” is often used to mask the use of harmful, naturally derived flavors.


7. Citric acid: A weak organic acid used as a flavoring agent and a preservative. Extracted from citrus fruits or made by fermentation of yeast or mold. May contain MSG. May be genetically modified.

Health effects: If MSG sensitive, may provoke symptoms.

I've been drinking diet coke for 40 years. i go between 3 large to 1 small to none at all for a month or so. too many make me edgy. but small to medium calm me down if i'm anxious. GO FIGURE!! everything in moderation, folks. my mother in law will be 100 and has done every "bad" thing in moderation her entire life. let's all just live and be happy!i am the picture of health, 115 lbs and eat a great diet.my 3 adult kids are healthy. ( i did give it up for the 9 months each time)

who knows? but life is short and there's always a bus or car ready to run you down, so enjoy!!

Some of us are fortunate enough to be blessed with strong bodies when it come to eating unhealthy foods or other bad habits such as smoking. The rest of us however, tend to react negatively over time when we abuse our bodies.

Just because I may be run over tomorrow doesn't mean I'm going to stop taking care of myself today. I eat healthy so that I may live life to the fullest. No big belly to slow me down.

So true I take my health seriously. When you get old that when our body breaks down some sooner and wonder why we have so much complications. Eat right, exercise, sleep early, plenty of alcanize water, fresh air in the country away from city stress is the best way to live. And not to forget to get along with our fellow man and love for God.
