What You'll Learn
Carbon dioxide gas in soda
Carbon dioxide is added to sodas to give them their fizz. The gas is added to the water in soda when it is very cold so that it can hold a lot of gas. Pressure is also used to put more gas into the water than it could normally hold at that temperature. When a can of soda warms up or is shaken, the extra gas is released. When you open the can and release the pressure, the carbon dioxide comes out of the soda and into the air.
Carbon dioxide is highly soluble in water, making it the most soluble of the common, non-toxic gases with high solubility. It is also comparatively more stable than other gases. This stability means it does not produce nasty byproducts when mixed with cold beverages. It also gives soda a slight acidic taste and a tingle on the tongue.
When soda is consumed, the body warms the liquid, and the carbon dioxide is released as gas and expands in the stomach. This can cause bloating, discomfort, a sensation of fullness, and a desire to burp.
To reduce these negative symptoms, it is recommended to drink soda slowly or in small amounts. It is also suggested to avoid drinking soda on an empty stomach and to pay attention to how soda impacts individual stomach sensitivities.

Artificial sweeteners and glucose intolerance
Artificial sweeteners are among the most widely used food additives worldwide, regularly consumed by lean and obese individuals. They are considered safe and beneficial due to their low-calorie content. However, scientific data supporting their benefits is sparse and controversial.
Research has shown that non-caloric artificial sweeteners (NAS) can induce glucose intolerance by altering the gut microbiota. Eran Elinav and colleagues demonstrated that the three most commonly used non-caloric artificial sweeteners—saccharin, sucralose, and aspartame—directly induce a propensity for obesity and glucose intolerance in mice. These effects are mediated by changes in the composition and function of the intestinal microbiota. Furthermore, these deleterious metabolic effects are transferable to germ-free mice through faecal transplantation. Similar NAS-induced dysbiosis and glucose intolerance have been demonstrated in healthy human subjects.
The consumption of sugar-sweetened beverages, artificially sweetened beverages, and fruit juice has been linked to the incidence of type 2 diabetes. Specifically, the habitual consumption of sucralose may affect glucose metabolism more strongly when taken with carbohydrates. This suggests that the effects of non-nutritive sweeteners (NNS) may depend on the co-consumption of other dietary compounds. For example, the impact of NNS on individuals following a low-carbohydrate diet may differ from those consuming high-carbohydrate diets.
Additionally, non-nutritive sweeteners can promote the dissemination of antibiotic resistance through conjugative gene transfer. The artificial sweetener Splenda has been shown to promote gut proteobacteria, dysbiosis, and myeloperoxidase reactivity in Crohn's disease-like ileitis.
While the exact mechanism by which artificial sweeteners induce glucose intolerance is still being elucidated, the current understanding calls for a reassessment of the massive usage of artificial sweeteners.

Cardiovascular complications
While the exact effects of artificially sweetened drinks on health are not yet fully understood, there is evidence of a link between diet soda and cardiovascular complications.
One study found that people who drank diet soda every day had a 36% greater risk of developing metabolic syndrome and a 67% greater risk of developing diabetes. Both of these conditions greatly increase the odds of having a stroke or heart attack. Another study found that regular consumption of artificial sweeteners is associated with a risk of developing cardiovascular complications, including glucose intolerance and type 2 diabetes.
The caffeine in diet soda may also be a factor in cardiovascular complications. Caffeine can increase the heart rate, which can be problematic for people with underlying heart conditions. Additionally, the artificial sweeteners in diet soda may negatively affect the gut microbiome, which plays a key role in heart health.
It is important to note that the research on the link between diet soda and cardiovascular complications is ongoing and has produced mixed results. While some studies have found an association between diet soda consumption and cardiovascular risks, others have not found a significant association after controlling for confounding factors. More research is needed to establish a direct causal relationship.

Tooth enamel erosion
While the exact cause of gas due to Diet Pepsi is unclear, it is likely due to the carbonation in the drink. The bubbles in soda are caused by carbon dioxide gas, which can cause bloating, discomfort, and a desire to burp. The high sugar content and artificial sweeteners in Diet Pepsi can also lead to digestive distress, including nausea, cramping, and diarrhea.
Now, regarding tooth enamel erosion:
Drinking Diet Pepsi can indeed contribute to tooth enamel erosion. This is due to the presence of acids in the drink, which alter the pH balance in the mouth and reduce the surface hardness of the enamel. Enamel erosion can cause tooth sensitivity, and once it occurs, it cannot be reversed, affecting individuals for their whole lives.
The Mississippi Department of Health has identified Pepsi as one of the most acidic soft drinks on the market. The acids in these drinks can erode tooth enamel, which is the outermost protective layer of the teeth. This erosion can then extend to the next layer, the dentin, and even affect composite fillings. Poor oral hygiene can exacerbate this issue, leading to severe tooth decay and cavities.
To minimize the risk of tooth enamel erosion, it is advisable to limit the consumption of soft drinks, including Diet Pepsi. Drinking in moderation, such as limiting yourself to one soft drink per day, can help reduce the damage. Additionally, drinking quickly and opting for less acidic beverage choices can also help. Fluoride and remineralizing toothpastes have also been found to be effective in inhibiting enamel erosion.
While diet soda does not contain sugar, it is still highly acidic. Studies have shown that both regular and diet soda can negatively affect the surface roughness of tooth enamel, indicating their contribution to tooth erosion. The frequency and length of exposure to these acids are crucial factors in determining the extent of erosion. Therefore, reducing the consumption of Diet Pepsi and similar drinks can help prevent tooth enamel erosion and its associated consequences.

Weight gain and obesity
The link between drinking diet soda and weight gain is a topic of ongoing debate. While some studies suggest that diet soda may contribute to weight gain and obesity, others indicate that it can aid in weight loss. The available research presents mixed findings, and more high-quality studies are needed to reach a definitive conclusion.
Several studies have linked the consumption of diet soda to an increased risk of obesity and metabolic syndrome. For example, a study of 9,000 middle-aged men and women over four years found that those who drank diet soda were more likely to become obese and develop metabolic syndrome. Additionally, research has suggested that diet soda may increase appetite and cravings for sweet, high-calorie foods. This effect may be due to the stimulation of hunger hormones, alteration of taste receptors, and triggering of dopamine responses in the brain. Some studies have also found that artificial sweeteners can damage the area of the brain that signals when to stop eating, leading to increased food consumption and weight gain.
On the other hand, some studies have shown that replacing sugar-sweetened drinks with diet soda can result in weight loss. Proponents of diet soda argue that low-calorie sweeteners can help reduce overall calorie intake and aid in maintaining a healthy weight. However, it is important to note that drinking diet beverages alone may not be sufficient to counter overeating. Maintaining a healthy weight requires balancing calories consumed with calories burned.
The conflicting findings in the research may be due to various factors, such as reverse causation, where people at risk for obesity may be more likely to choose diet beverages, and potential bias in industry-funded studies. While the link between diet soda and weight gain is not conclusive, it is generally recommended to prioritize plain water or unsweetened tea as healthier alternatives to reduce the potential negative effects of carbonated beverages on appetite and weight.
