2. Pepsi One - uses acesulfame potassium and sucralose 
3. Diet Rite - uses a combination of sucralose and acesulfame potassium

Why Aspartame is Dangerous to Your Health?   

Aspartame is an artificial sweetener that is commonly used in diet sodas as a low-calorie alternative to sugar. However, there is some concern about its potential health effects. Some of the potential risks associated with aspartame include: 

1. Neurological effects - some studies have suggested that aspartame may have a negative impact on neurological health, including headaches, dizziness, and seizures. 
2. Metabolic effects - aspartame has been linked to an increased risk of metabolic syndrome, which includes a range of health issues such as obesity, high blood pressure, and high cholesterol. 
3. Cancer risk - some studies have suggested a potential link between aspartame and certain types of cancer, although the evidence is not yet conclusive.

Aside from the potential risks associated with aspartame, there are other reasons why you may want to consider cutting back on diet soda or avoiding it altogether: 

1. Dental health - diet soda is highly acidic, which can erode tooth enamel and increase the risk of cavities. 
2. Dehydration - the caffeine and diuretic effects of diet soda can lead to dehydration, which can have a range of negative health effects. 
3. Weight management - while diet soda is marketed as a low-calorie alternative to regular soda, some studies have suggested that it may actually contribute to weight gain by disrupting metabolic processes and increasing sugar cravings.

If you are looking for a healthier alternative to diet soda, there are many options to choose from. One of the best options is filtered water, which is both refreshing and hydrating. Other healthy alternatives include: 

1. Herbal tea - many herbal teas are naturally sweet and can provide a range of health benefits, including reducing inflammation and promoting relaxation. 
2. Infused water - adding fresh fruit or herbs to your water can add flavor and nutrients without adding calories or artificial sweeteners. 
3. Sparkling water - carbonated water can provide the refreshing fizz of soda without the added sugar or artificial sweeteners.
