Both diet and regular soda may increase insulin levels.


  • Some people swap out regular sweetened beverages for diet versions, but their long-term effects on health still need to be determined.

  • According to a recent study, dieting and regular soft drinks can raise salivary insulin levels.

  • The findings suggest that overindulging in either diet or regular soft drinks could cause harm. Nevertheless, I need to do more investigation to gain a better understanding of this.

Many people are aware of the adverse effects that sugary beverages can have on health and make an effort to reduce their consumption. An alternative is to choose diet drinks which contain artificial sweeteners and fewer calories. However, the long-term impact of these drinks on health has yet to be fully understood.

The research, recently published in the Food Research International, examined the effects of different drinks on insulin levels in saliva.

The research indicated that consuming regular or diet soft drinks led to higher salivary insulin levels. Additionally, it was observed that the artificial sweetener aspartame in saliva increased when diet soft drinks were consumed.

This study adds to the mounting evidence that diet soda poses potential risks instead of sugar-sweetened beverages. Further investigation is necessary to determine the full implications of this and what advice should be given concerning using artificial sweeteners.

Do diet sodas raise insulin levels?

The study examined the effects of a single-blind method, with fifteen healthy adults aged 18-45 who had no prior diabetes or abnormal blood sugar levels.

To investigate how certain drinks affected four key elements, the researchers eliminated sure participants based on criteria that might alter saliva levels and taste judgements.

  • Excretion of aspartame in saliva, a prevalent artificial sweetener.

  • Insulin levels in saliva play a crucial role in regulating glucose utilisation by the body's cells; disturbances in insulin levels and responsiveness can contribute to diabetes.

  • Measurement of total protein (TP) levels.

  • Assessment of alpha-amylase (AMI), an enzyme vital for sugar digestion in the body.

Contrary to previously thought, this study suggests that diet soft drinks may cause a person's insulin levels to rise.

It is a common assumption that insulin is not released after diet soda since it does not contain sugar and should not raise blood sugar. However, whether artificial sweeteners can raise blood sugar and insulin levels has been debated. When consuming regular soda, the carbohydrates increase blood sugar levels, releasing insulin.

Impact of certain drinks on insulin levels

For the data collection process, participants were asked to consume a range of beverages while blindfolded. This included diet soft drinks, regular soft drinks, mineral water with artificial sweeteners, a small amount of sucrose mixed into plain water, and plain water.

After collecting saliva samples from participants, the researchers' analysis revealed that the levels of total protein and alpha-amylase were unaffected by any of the beverages consumed.

Therefore, the research focused on the effects of the drinks on aspartame and insulin levels.

Initially, researchers found that aspartame stayed in saliva for a prolonged period, suggesting that it may remain in the body for an extended time and can affect the body's reaction to the sweetener.

The researchers discovered that saliva insulin levels were higher following regular and diet soft drinks. They suggested that these salivary insulin levels may indicate serum insulin levels.

Results of the study showed that drinking diet soft drinks, particularly those containing aspartame, was associated with higher levels of salivary insulin.

This recent study, albeit small, had a unique approach to examining saliva after consuming regular and diet sodas. It is well-known that both types of drinks come with health risks.

Recent studies have shown that those who consumed sugary and diet sodas had elevated insulin levels after an hour. Despite their promotion as aids for weight loss and improved blood sugar regulation, the research reveals that these drinks have the opposite effect.

Clinical implications

The study demonstrated that drinking diet soda leads to increased insulin levels, even though these drinks are sugar-free and low in calories.

Insulin release is essential in maintaining blood sugar balance, aiding metabolism, and stimulating muscle growth. However, when levels are too high, it can cause additional problems, such as weight gain from excessive fat deposition and increased cardiovascular risk from narrowed blood vessels and high blood pressure.

People with diabetes may be at a greater risk of developing severe health complications such as retinopathy, erectile dysfunction, neuropathy, kidney disease, myocardial infarction, and stroke due to prolonged exposure to high insulin levels or incorrect insulin usage. Such complications can lead to increased morbidity and mortality.

If further research confirms these findings, it could lead to a decrease in the consumption of diet sodas. People may be more hesitant when considering their use than viewing them as an adequate alternative to regular soft drinks.

Further research is needed to determine the effects of sugary drinks on health measures. However, simply replacing sugary beverages with those containing aspartame may not confer any health benefits and could be detrimental.

People should be informed about the potential risks to metabolic health associated with consuming diet drinks containing artificial sweeteners.

Study limitations and continued research

The study's small size and the skewed gender ratio of the participants limit the scope of this research. Furthermore, the short duration of the study requires further research with a more extended follow-up period to be conducted to confirm the findings.

The inability to accurately measure acesulfame concentrations in artificially sweetened beverages may have altered the results, necessitating additional research.

The study's authors noted that their data was limited to the ingredients they tested and that other components in the soft drinks could have affected the study's outcomes. As such, further research is needed to confirm the results.

This research was narrow in scope and only drew from a small sample size. Furthermore, the study was not conducted double-blind, potentially leading to bias in the results. Additionally, since the survey was conducted over a short period, it is impossible to extrapolate the findings to long-term health outcomes related to diabetes.

As a result, further investigation is necessary to influence medical advice and decisions about health potentially.

The research offers a glimpse into how the consumption of aspartame, salivary secretion, and insulin levels are related. It can be used as the starting point for further exploration into the effect of different beverages, including those with aspartame, on general health for people with diabetes.
