• A new investigation reveals product labels fail to disclose actual aspartame percentages, hindering consumers from monitoring intake.
• The study reveals which products most commonly contain the controversial sweetener, with chewing gum, yoghurt and fizzy drinks all being prone.
• Certified nutritionist weighs in on why more transparency around aspartame contents is crucial, due to additive’s concerning effects. 

A new study has investigated the true aspartame content in everyday household food and drink items. The findings raise concerns about the lack of transparency surrounding the presence of aspartame in commonly consumed products.

Data analysts at naturally-infused water brand, DASH Water, conducted an analysis of products from one of the UK’s largest supermarkets to investigate the use of the artificial sweetener.

Despite the widespread use of aspartame, the study underscored a significant issue – products do not disclose the percentage of aspartame included. This lack of transparency exacerbates the problem, as consumers are left in the dark about their aspartame intake, making it difficult to monitor and potentially leading to overconsumption. Without knowing the exact content in popular products, consumers face challenges in making informed decisions about their dietary choices.

While the exact percentages of aspartame are unclear, the findings did reveal the products that most commonly contain the additive. It was found that 100% of chewing gum products contain aspartame. In other food categories, 40% of jelly products, 17% of low-fat/fat-free yoghurts, and 9% of mints contain this artificial sweetener. Even immune support vitamins and supplements, crucial for health-conscious consumers, were not immune, with aspartame found in almost 1 in 10 products.

Turning attention to beverages, the results were equally concerning. Almost 3 in 5 sugar-free fizzy drinks, and nearly 1 in 5 sugar-free squash and cordial drinks contained undisclosed amounts of aspartame.

Qualified and clinically trained nutritionist, Lara Buckle, The Wellness Detective, calls for more transparency around aspartame content:

“It is essential to understand the potential effects of aspartame overconsumption on the human body and why moderation is crucial. Aspartame, a low-calorie artificial sweetener, is widely used as a sugar substitute in various diet and low-calorie products. While regulatory agencies like the FDA consider it safe for consumption, concerns persist. Overindulgence in aspartame can lead to adverse outcomes.

Metabolically, aspartame has been linked to disruptions in calorie intake regulation and blood sugar, contributing to insulin resistance, a precursor to type 2 diabetes. Emerging research also indicates that artificial sweeteners, including aspartame, may affect the composition of gut microbiota, which can have far-reaching consequences on metabolism and overall health. Moreover, individuals sensitive to aspartame can experience adverse reactions such as headaches and migraines. While such sensitivity is not common, it underscores the need for individualised dietary choices and moderation.

Over-reliance on aspartame can alter taste preferences, potentially diminishing the appeal of naturally sweet and nutritious foods. Lastly, it can create a psychological effect where individuals feel they can compensate for reduced calorie intake by making poor food choices elsewhere in their diet.

To maintain a balanced and nutritionally sound eating pattern, it is vital to moderate aspartame consumption and prioritise whole, unprocessed foods whenever possible. While aspartame can be a valuable tool for those managing their sugar and calorie intake, a well-rounded diet remains the cornerstone of good nutrition.”

The absence of detailed information on aspartame content poses challenges for consumers striving to monitor their intake. Our findings underscore the need for greater transparency and disclosure in the food and beverage industry to empower consumers to make informed choices about their dietary preferences.
