“Is Pepsi better than Cola?”

. Dr D.A Grant:

This is difficult to answer, since Pepsi is a cola. Perhaps you mean “Is Pepsi better than Coke”, in which case I advise you to never find out. This meta-analysis of 88 studies concluded that continued soft drink consumption leads to unhealthy weight and increased risk of Type 2 Diabetes, although the effects were less significant if the studies were funded by the soft drinks industry, which is a story in itself. However, colas do apparently have some potential health benefits if you have gastric phytobezoar dissolution, so if this is your problem, it is your chance for the taste test. When taking the test, make sure you consume from cans or glass bottles, so that they can be recycled. Recycling single use plastic is largely a myth; a myth which is destroying our environment even faster than climate change.


The debate over whether Pepsi or Cola is better is largely a matter of personal preference. While both soft drinks contain similar ingredients, such as carbonated water, high fructose corn syrup, and caramel color, they have different taste profiles. Pepsi is generally considered to have a slightly sweeter taste, while Cola is typically more acidic. Some people prefer the taste of Pepsi because of its citrus notes, while others prefer the caramel flavor of Cola. Ultimately, the decision between the two comes down to individual taste. It is worth noting, however, that both drinks are high in sugar and should be consumed in moderation as part of a healthy diet. Additionally, some people may prefer to avoid soft drinks altogether due to the health risks associated with consuming too much sugar and artificial sweeteners.
