Studying the Connection Between Generational Anxiety and artificial sweetener

Might the sugar-sweetened beverages ingesting be contributing increased anxiety levels? According to a study examining , an artificial sweetener, on mice, it’s a potential worth looking into more.

aspartame has been a common ingredient in beverages and foods low in calories. It is now present in around 5,000 distinct goods that both adults and kids eat.

In carefully designed mood tests, mice that were given free access to water containing aspartame at a dosage corresponding to 15 percent of the FDA’s recommended maximum daily intake for humans generally showed signs of increased anxiety.

The fact that the impacts may be observed in the animals’ progeny for up to two generations is what really surprises me.

According to neurologist, “what this study is showing is we need to look back at the environmental factors, because what we see today is not only what’s happening today, but what happened two generations ago and maybe even longer.”

A range of maze tests were used to gauge anxiety in mice across multiple generations. In order to determine how the genes in the tissue were expressed, the researchers also performed RNA sequencing on important regions of their neurological systems. The amygdala, a region of the brain linked to the control of anxiety, underwent notable alterations, according to the researchers.

Aspartame is known to break down in the stomach into aspartic acid, phenylalanine, and methanol, all of which have the potential to impact the central nervous system. Concerns have previously been raised over certain people’s possible negative reactions to the sweetener.

All generations of mice ceased exhibiting anxiety-like behaviors when doses of diazepam, a medication originally sold under the brand name Valium and frequently used to treat anxiety in people, were given. The drug functions by assisting in the regulation of the same brain pathways that aspartame alters.

Even while observing anxiety-like behaviors in mice is only a rough representation of comparable human emotions, the researchers saw distinct behavioral changes in the animals, which they connected to alterations in gene activity.

“It was such a robust anxiety-like trait that I don’t think any of us were anticipating we would see,” said , a graduate research . “It was completely unexpected. Usually you see subtle changes.”

The study builds on previous research conducted by the same group regarding the generational effects of nicotine usage on mice behavior. This time, the effects appear to be inherited through non-coding epigenetic modifications in the genes of mouse sperm cells.

This could be a similar situation, the team speculates. Put another way, not only the people who use the artificial sweetener but also their offspring and the offspring of their offspring may be in danger. Although the exact mechanism is yet unknown, it is consistent with growing data that suggests epigenetic marks can, in fact, persist across many generations.

Although the connection between aspartame and anxiety has been explored previously, no change in anxiety-like behavior in rats fed artificial sweeteners has been observed in other animal studies, indicating that much more research is necessary to fully comprehend the situation.

Nevertheless,  associates are warning caution in light of these findings. Previous studies have connected artificial sweeteners to cancer and altered gut flora to glucose intolerance; anxiety may now also be a factor to take into account.

Even if these identical findings still need to be verified in humans, the discovery that mice exhibit anxiety is a good cause to carry out additional research.

“Extrapolation of the findings to humans suggests that aspartame consumption at doses below the FDA recommended maximum daily intake may produce neurobehavioral changes in aspartame-consuming individuals and their descendants,” the researchers reported

“Thus, human population at risk of aspartame’s potential mental health effects may be larger than current expectations, which only include aspartame-consuming individuals.”
