What You'll Learn

Diet Dr Pepper contains artificial sweeteners
While Diet Dr Pepper contains no sugar, it does contain artificial sweeteners. These sweeteners are designed to impart a sweet taste without the calories or glucose effects of sugar. However, they have been linked to various adverse health effects. For example, research indicates that artificial sweeteners may affect metabolism, potentially leading to weight gain and insulin resistance. This is especially counterproductive for people using these sweeteners to manage their weight, prevent diabetes, or follow a keto diet.
One of the artificial sweeteners used in Diet Dr Pepper is aspartame, which has been linked to cancer and is considered a carcinogen by the International Agency for Research on Cancer (IARC). Other studies suggest that artificial sweeteners can alter the gut microbiome, which has been linked to digestive problems, inflammation, and a weakened immune response. In addition, there is insufficient evidence that low-calorie sweeteners help reduce overall calorie intake, aid in weight loss, or improve overall health. Instead, they may condition people to crave sweet foods and, therefore, consume fewer servings of healthy foods.
The formula for Diet Dr Pepper dates back to 1962, and it has sometimes been marketed as tasting the same as regular Dr Pepper and sometimes differently. The original version of a soft drink usually has a different taste from its diet counterpart because sugar cannot simply be replaced with a sweetener without changing the overall taste. Each sweetener has a distinct taste, and people have different preferences for sweeteners, so companies create different sugar-free variants to cater to a wider range of tastes.
While Diet Dr Pepper contains artificial sweeteners, Dr Pepper Zero Sugar uses a different blend of sweeteners, resulting in a different order of ingredients. The "Zero" branded drinks are closer in flavor to the high-fructose corn syrup-sweetened drinks, while the "Diet" branded drinks are considered to use an excessive amount of sweeteners. Ultimately, the choice between the two comes down to individual taste preferences.

These sweeteners may negatively impact your metabolism
While diet drinks like Diet Dr Pepper contain no sugar, they are sweetened with artificial sweeteners such as aspartame, acesulfame-K, and sucralose. These low-calorie sweeteners are designed to impart a sweet taste without the calories or glucose effects of sugar. However, research suggests that they may negatively impact your metabolism.
Artificial sweeteners have been linked to potential weight gain and insulin resistance, which can be counterproductive for people using them to manage their weight, prevent diabetes, or follow a keto diet. For example, studies have shown that aspartame, found in Diet Dr Pepper, is considered a carcinogen by the International Agency for Research on Cancer (IARC). Additionally, artificial sweeteners can alter the gut microbiome, leading to digestive problems, inflammation, and a weakened immune response.
Furthermore, there is insufficient evidence that low-calorie sweeteners help reduce overall calorie intake, aid in weight loss, or improve overall health. On the contrary, they may condition people to crave sweet foods and consume fewer servings of healthy foods. This can lead to a preference for highly processed, sugary foods and drinks, which can negatively impact metabolic health.
The exact mechanism by which artificial sweeteners affect metabolism is not yet fully understood. However, it is speculated that they may interfere with the body's ability to regulate blood sugar and insulin levels, leading to metabolic disruptions. Additionally, artificial sweeteners may alter the composition and function of the gut microbiome, which plays a crucial role in metabolism and overall health.
While the impact of artificial sweeteners on metabolism is a growing area of research, it is recommended that people limit their consumption of these sweeteners and opt for healthier alternatives. Natural sweeteners like stevia or monk fruit extract may be better options, although more research is needed to fully understand their long-term effects as well.

Sweeteners can also alter your gut microbiome
A standard 12-ounce can of regular Dr. Pepper contains approximately 40 grams of sugar, which is quite a significant amount. To put it in context, the American Heart Association recommends a daily sugar intake limit of 36 grams for men and 25 grams for women. This is why many people opt for sugar-free or diet versions of their favorite drinks. However, artificial sweeteners, which are often several hundred thousand times sweeter than sucrose, have been linked to various health risks.
Artificial sweeteners have been associated with a variety of changes in the gut microbiome, which is the community of beneficial bacteria in the digestive tract. The gut microbiota can metabolize non-nutritive sweeteners (NNSs) by producing a variety of biological effects. NNSs can be used as a carbon source by some strains of gut bacteria, leading to changes in their metabolic activity and modulating the production of compounds such as acetate, propionate, and butyrate. These compounds have an impact on glucose metabolism and host metabolism and can exert an anti-inflammatory effect.
Additionally, NNSs can reduce the abundance of beneficial gut bacteria, such as Bifidobacterium and Lactobacillus, and increase the abundance of pathogenic bacteria, such as Clostridium difficile and E. coli, which can cause infections and inflammation in the gut. In a controlled study, Cedars-Sinai investigators analyzed the duodenal luminal microbiome in subjects consuming non-aspartame non-sugar sweeteners, aspartame alone, or no sugar substitutes. They found significant differences in both stool and duodenal microbial diversity and composition compared to the control group.
The consumption of NNSs has also been linked to the development of glucose intolerance through the induction of compositional and functional alterations to the intestinal microbiota. While the consumption of NNSs reduces blood glucose due to a lower carbohydrate load, excessive consumption may cause gastrointestinal symptoms such as gas or laxative effects in some people.
Overall, the impact of sweeteners on the gut microbiome is a complex and evolving area of research, and more studies are needed to fully understand the relevance of individual nutrients and lifestyle factors on microbiota changes.

Artificial sweeteners may condition people to crave sweet foods
A standard 12-ounce can of regular Dr. Pepper contains approximately 40 grams of sugar, which is around 10 teaspoons and contributes around 150 calories from sugar alone. The high sugar content means that just one can of Dr. Pepper exceeds the recommended daily sugar intake limit of 36 grams for men and 25 grams for women suggested by the American Heart Association.
To avoid the excessive sugar content of regular Dr. Pepper, consumers often opt for the diet version, which is sweetened with artificial sweeteners. However, research suggests that artificial sweeteners may have adverse metabolic effects, such as weight gain, insulin resistance, and an increased risk of diabetes. Artificial sweeteners have also been linked to cancer and are considered carcinogenic by the International Agency for Research on Cancer (IARC).
Artificial sweeteners are non-nutritive, meaning they provide few or no calories or nutrients. They are derived from plants, herbs, or sugar itself and have a much higher sweetness intensity than sugar. This allows for smaller quantities to be used in food and drink products. However, the excessive sweetness of artificial sweeteners may condition people to crave more sweet foods.
Studies have found that consuming artificial sweeteners can interfere with the brain's reward circuitry, driving increased food consumption. Specifically, when the brain detects sweetness without receiving the expected caloric energy, it compensates by increasing the palatability of sugar, leading to a higher overall calorie intake. This phenomenon has been observed in fruit flies, with flies fed artificial sweeteners consuming 30% more calories than those fed sugar.
Additionally, prolonged consumption of artificial sweeteners may increase sensitivity to sugar, making it more pleasurable and desirable. This increased appetite for sweet foods has been observed in obese individuals, who tend to have lower sensitivity to sweetness and may consume more sugar-rich foods to achieve the desired taste intensity.
While the link between artificial sweeteners and increased cravings for sweets is not yet fully understood, the available evidence suggests that frequent exposure to these sweeteners may play a role in conditioning people to crave sweet foods.
