Is Diet 7 UP Bad For You?



Short answer

Diet 7 Up is a non-caffeinated "diet" soft drink that is loaded with aspartame, has no mineral or vitamin content and no nutritional value.

Long answer

One of the most toxic ingredients in Diet 7-Up is aspartame.  This artificial sweetener has been linked to multiple serious health challenges. Recent studies have shown that artificial sweeteners actually increase weight gain. They fail to satisfy cravings and often intensify hunger. Aside from contributing to weight gain, it has been linked to serious birth defects and cancers of the brain as well as other neurological disorders. Aspartame consists of aspartic acid and phenylalanine, which when broken down in the system produces methanol, which can be toxic in high amounts. Metabolites from methanol can be the cause of central nervous system depression and other disorders that lead to metabolic acidosis and coma.

Aspartame has been used as an artificial sweetener since the 1980’s and is currently found in thousands of products. It is approved by the Food and Drug Administration (FDA) for use in food and beverages as a substitute for sugar with the recommended daily intake of 50 milligrams per every kilogram of body weight. In the late 1990’s, products containing aspartame were the focus of 80% of complaints about food additives to the FDA. Since the onset of its use in the United States, its safety in regards to consumption has been highly controversial.

Aspartame has been linked to numerous hazardous side effects including a greater risk of birth defects in women who consume aspartame while pregnant. Aspartame has also been linked to certain cancers (there has been a 300% increase in brain cancers since its release as well as increases in non-Hodgkin’s lymphoma and leukemia).  Aspartame is also associated with seizures, headaches, dizziness, weight gain, extreme fatigue, type 2 diabetes, metabolic syndrome, lupus, Alzheimer’s disease, fibromyalgia, general musculoskeletal pain and multiple sclerosis. The side effects attributed to aspartame can occur gradually over time or can be acute reactions to the chemical. Immediate reactions can include trouble with vision and eyes, ringing in the ears, heart palpitations and shortness of breath.

Another detrimental additive in diet 7-Up is EDTA (Ethylenediaminetetraacetic Acid). Although deemed safe by the FDA this chelating agent (which binds heavy metals in the system) has been linked to a plethora of health issues. EDTA is a chemical created from the combination of formaldehyde, sodium cyanide, and ethylenediamine. This poison is added to many sodas, processed foods including sandwich spreads, salad dressings, sauces and numerous canned or pickled foods. The purpose is to increase shelf life by preventing rancidity, discoloration, and the separation of oils and fats.

EDTA has various side effects including depletion of important metals/vitamins, hypotension, headaches, migraines, abdominal discomfort, and the lowering of blood sugar. More troubling is the long-term risks of toxicity and kidney damage. An additional concern is attributed to the unknown side effects of the possible build up in the body over time. As a whole, people are using more artificially preserved items now than ever before in history. The collective overuse of many toxic and carcinogenic chemicals create a problem for researchers in ascertaining which destructive substances are responsible for specific long-term side effects.

Another nasty ingredient in diet 7-Up is potassium benzoate.  This chemical is used as a preservative but serious health effects have been associated with this toxin. These effects include hyperactivity, dizziness, insomnia, DNA damage and significant neurologic disease such as Parkinson’s.

When combined with vitamin C, potassium benzoate can form benzene, a known carcinogen. Vitamin C is a necessary part of our diet and is found in many fruit and vegetables. Because of the presence of this preservative in salad dressings, sodas, and fruit juice, it is almost inevitable that this combination will occur in most people’s diets. Other factors that can affect the rate at which benzene is formed in potassium-benzoate-containing-foods include heat, light and shelf life.

This formation of benzene that occurs from potassium benzoate and vitamin C is the most important to note. If you eat and drink foods containing these ingredients often, you can be at risk for various benzene health consequences. Long-term exposure can cause bone marrow to not be able to produce new red blood cells properly, which can lead to anemia. The blood cell changes also affect white blood cell loss and decrease antibodies, which together means a less active and stable immune system. You get further exposure to benzene from tobacco smoke, gasoline fumes, glue, paint, furniture waxes, and detergent.

There are many great alternatives to diet 7-up. Organic juices and natural sodas with no artificial sweeteners or preservatives are a wonderful substitute. And of course, water should always be part of everyone’s daily routine.
