A study published in April 2017 by Boston University found a link between sugary drinks and memory loss, reduced brain volume, and an increased risk of stroke and dementia. While the study did not differentiate between types of artificial sweeteners, it did find that people who consumed at least one artificially sweetened drink per day had a three times higher risk of having a stroke or developing dementia. Another study found that the Standard American Diet (SAD) can cause shrinkage of the left hippocampus, a portion of the brain involved in memory, learning, mood regulation, and depression. This study is significant because the left hippocampus is the first part of the brain to deteriorate in Alzheimer's disease. While the exact mechanism by which artificial sweeteners may cause harm is still unknown, some hypotheses include altering the brain's perception of sweet and imbalancing the microbiome, which interacts with key neurotransmitters.

What You'll Learn
The impact of artificial sweeteners on the brain
Research has indicated that individuals who consume at least one artificially sweetened drink per day have a higher risk of experiencing stroke and dementia later in life. This finding has been supported by multiple studies, suggesting a correlation between artificial sweeteners and negative outcomes. However, it is important to note that the specific types of artificial sweeteners involved and their exact mechanisms of action are still subjects of ongoing research.
One hypothesis suggests that artificial sweeteners may disrupt the balance of gut bacteria, which in turn affects the brain. Given the bacterial superhighway from the gut to the brain and their interaction with key neurotransmitters, this theory highlights the potential for gut bacteria to influence brain health. Additionally, artificial sweeteners may alter the brain's perception of sweetness, leading to potential overconsumption of sugary foods and drinks.
While the exact mechanisms are still under investigation, the potential impact of artificial sweeteners on the brain is concerning. It is worth noting that some studies have suggested that the correlation between artificial sweeteners and adverse brain effects may be influenced by other factors. For example, individuals who consume more artificial sweeteners may already be at a higher risk for certain health conditions due to their overall lifestyle choices or state of health.
In conclusion, while more research is needed to fully understand the impact of artificial sweeteners on the brain, current evidence suggests a potential link between their consumption and negative outcomes such as brain shrinkage, stroke, and dementia. To promote optimal brain health, it is generally recommended to limit the consumption of artificial sweeteners and opt for healthier alternatives, such as infused water or naturally flavored drinks.

The effect of aluminium cans on the brain
While there is no direct evidence that links aluminium cans to brain shrinkage, there is research that suggests a link between diet drinks and brain health. A study by Boston University found that people who consume at least one artificially sweetened drink per day have a three times higher risk of having a stroke or developing dementia. However, it is unclear whether the drinks themselves are the cause of these issues or if it is related to the health and lifestyle choices of those who consume them.
The study also suggests that the correlation could be due to the "secret" ingredients in soft drinks, such as sodium benzoate, which has been linked to memory impairment, motor coordination issues, and increased levels of malondialdehyde (MDA) in the brain. Another potential cause could be the aluminium container/can used for soft drinks. When a can is opened, the liquid passes over an edge with fresh aluminium, and some aluminium will be dissolved in the acidic liquid.
Additionally, diet sodas are designed to trick the brain into thinking it is receiving an extra dose of glucose, but the brain eventually adapts, leading to various effects that are still under investigation. One theory suggests that diet drinks may imbalance the gut microbiome, which interacts with key neurotransmitters, potentially causing unpredictable results.
It is worth noting that the Standard American Diet (SAD), which includes refined carbohydrates, sugary foods and beverages, and higher amounts of saturated fats, has been linked to shrinkage of the left hippocampus, a portion of the brain involved in memory, learning, and mood regulation. This finding has significant implications for our understanding of Alzheimer's disease, as the left hippocampus is the first part of the brain to deteriorate in this disease.

The link between diet cola and stroke
While the direct link between diet cola and stroke is not yet fully understood, there is growing evidence that suggests a correlation between the two. A study published in April 2017 by Boston University researchers found that people who consume at least one artificially sweetened soda per day have a three times higher risk of experiencing a stroke or developing dementia. This study adds to the growing body of evidence that suggests the negative health impacts of sugary drinks and artificially sweetened beverages.
The study by Boston University researchers included 2,888 men and women and linked sugary beverages, such as sodas and fruit juices, to memory loss and reduced brain volume, particularly in the area of the brain responsible for memory and learning. The follow-up study, which focused on diet soda consumption, revealed a concerning link to stroke and dementia. It is important to note that the researchers used soda consumption as a marker for sweetener intake, which may be the primary factor contributing to these health issues.
Another study published in BMC Medicine found that the Standard American Diet (SAD) is associated with shrinkage of the left hippocampus, a part of the brain involved in memory, learning, mood regulation, and depression. This study analyzed the dietary habits and health assessments of 2,551 Australians aged 60 to 64, providing further evidence of the link between diet and brain health.
While the exact mechanism remains unclear, scientists have proposed several hypotheses. One theory suggests that diet drinks may disrupt the balance of gut bacteria, which has a direct connection to the brain through a bacterial superhighway. Another possibility is that artificial sweeteners alter the brain's perception of sweetness over time. Additionally, it is worth considering the potential impact of other ingredients in soft drinks, such as the aluminium in cans, or the effects of caffeine consumption on the brain.
It is important to note that some critics argue that the correlation between diet cola and health issues may be influenced by other factors. For example, people who are obese or have unhealthy lifestyles may be more likely to consume diet drinks, and their health conditions could be contributing factors to the observed correlations.
In conclusion, while the direct causal link between diet cola and stroke remains to be definitively proven, the existing research highlights a concerning correlation. More research is needed to fully understand the underlying mechanisms and to determine whether it is the diet cola itself or other related factors that contribute to the increased risk of stroke and other health issues.

The link between diet cola and dementia
A study published in April 2017 by researchers at Boston University found a link between diet cola and dementia. The study included 2,888 men and women and linked sugary beverages like sodas and fruit juices to memory loss and reduced brain volume, especially in the area of the brain that involves memory and learning.
In a follow-up study, the same researchers found that people who drink at least one artificially sweetened soda per day have three times the risk of having a stroke or developing dementia compared to non-diet soda drinkers. It is important to note that the researchers used soda consumption as a marker for sugar or sweetener intake, so it may not be the drinks themselves that cause the problems, but rather their sweeteners.
The study suggests that diet sodas are designed to trick the brain into thinking it is getting an extra dose of glucose, but the brain eventually adapts by overcompensating in other ways. This can lead to an imbalance in the gut microbiome, which has a bacterial superhighway to the brain and interacts with key neurotransmitters. Different artificial sweeteners in diet drinks have different effects, and there is ongoing debate about which causes what. For example, aspartame, the main ingredient in many diet drinks, has been linked to insomnia, headaches, and seizures, and in chronic cases, blindness, neurotoxicity, and memory loss.
Additionally, the consumption of sodium benzoate, found in many beverages, has been linked to impaired memory, reduced motor coordination, and increased malondialdehyde (MDA) levels in the brain, which can lead to attention deficit hyperactivity disorder (ADHD) in children. While the exact mechanisms are still under investigation, these studies suggest that diet cola and other artificially sweetened beverages may contribute to an increased risk of dementia.

The impact of diet cola on the hippocampus
Research has shown that diet cola and other artificially sweetened drinks may have a negative impact on the hippocampus, a part of the brain involved in memory, learning, mood regulation, and depression.
A study published in April 2017 by Boston University researchers found a link between the consumption of sugary beverages and memory loss and reduced brain volume, particularly in the hippocampus. In a follow-up study, the same researchers found that people who drank at least one diet soda per day had a three times higher risk of having a stroke or developing dementia. These findings suggest that artificial sweeteners in diet cola may contribute to negative health outcomes, including potential shrinkage of the hippocampus.
Another study published in BMC Medicine examined the impact of the Standard American Diet (SAD) on brain health. The results indicated that a diet high in refined carbohydrates, sugary foods and beverages, and saturated fats found in meats and cheeses was associated with a significantly smaller left hippocampus size. This study provides further evidence that dietary choices can influence hippocampus size and highlights the potential detrimental effects of consuming diet cola and other sugary drinks.
It is important to note that the exact mechanisms by which artificial sweeteners in diet cola may affect the hippocampus are not yet fully understood. Some hypotheses include the disruption of gut bacteria, alteration of the brain's perception of sweet tastes, and the presence of other ingredients in soft drinks, such as sodium benzoate or aluminium from cans.
While the direct causal relationship between diet cola consumption and hippocampus shrinkage requires further investigation, the current body of research suggests that reducing the intake of artificially sweetened beverages, including diet cola, may be beneficial for maintaining brain health and preserving hippocampus volume.

Frequently asked questions
Research has shown that people who drink at least one diet (artificially sweetened) cola a day are three times more likely to have a stroke or develop dementia. However, it is unclear whether the drinks themselves are the direct cause of these problems.
One theory is that diet drinks can imbalance the microbiome in our guts, which interacts with neurotransmitters that have a bacterial superhighway to the brain. Another theory is that diet cola is designed to trick the brain into thinking it's getting an extra dose of glucose, but the brain adapts to not receiving the added glucose by overcompensating in other ways.
Studies have shown that diet cola can lead to insomnia, headaches, seizures, and in chronic cases, blindness, neurotoxicity, and memory loss. It can also cause maternal consumption of soft drinks during pregnancy and the postnatal period, which can be linked to cognitive impairment and child obesity.
Instead of reaching for a diet cola, try jazzing up a glass of water with healthy add-ins like crushed strawberries and a sprig of mint, a slice of cucumber, or a cube of watermelon or other fresh fruit.
