- WHO recommends limiting sugar (free sugars) to approximately 25g per day for adults, which is about 6 sugar cubes.
- The "Satou-san" app allows you to easily check the sugar content of soft drinks by barcode, displayed in sugar cubes. You can also keep a history of your consumption.
- While the display is easy to understand, there are caveats such as the comprehensiveness of the database, delays in displaying new products, and the handling of artificial sweeteners.
- Effective ways to reduce sugar include creative alternatives for drinks, revisiting drinking timing, and learning to read labels. Even a sip of sugar can have an impact during ketosis.
The Sugar in Soft Drinks: A Closer Look at a Common Problem
Sweet drinks are convenient and delicious, and it's easy to find ourselves buying them. We often find ourselves reaching for them at convenience stores. However, "free sugars" (such as sugar) that can lead to rapid blood sugar spikes, obesity, and diabetes risk are often surprisingly abundant in beverages. In 2015, the World Health Organization (WHO) recommended that adults limit their daily intake of free sugars to approximately 25g (about 6 sugar cubes). Since sugar is also found in everyday meals and seasonings, it's possible to reach this guideline with beverages alone.
What You Can Do with the "Satou-san" App
Main Features and Ease of Use
The "Satou-san" is a free app that allows you to scan a product's barcode with your smartphone and instantly see its sugar content displayed visually with sugar cubes and in grams. When we tried it, the display was intuitive, and the "how many sugar cubes" presentation was very easy to understand, acting as a deterrent before drinking. It's also convenient for tracking habits, as you can check your consumption history by day and month.
Actual Display Examples and How to Use It
It's easy to use. Download and launch the app, select barcode scan with the + button, and point your camera at the beverage's barcode. The display will show something like "〇 sugar cubes (〇g)". For example, a 500ml sports drink might show that it accounts for about 98% of the recommended daily intake, which is often surprising.
Caveats and Limitations When Using the App
Data Accuracy and Coverage
To be honest, not all commercial products are covered. There can be delays in reflecting data for new and limited-edition products, and items with ambiguous ingredient labels may not be displayed accurately. Also, alcoholic beverages and mixed drinks can have complex sugar content, so we recommend checking the nutritional information on the label in conjunction with the app's display, rather than taking the display at face value.
Differences Between "Sugars" and "Natural Sugars"
The "free sugars" targeted by WHO include not only sugar but also honey, syrups, and sugars from fruit juices. While sugars in whole fruits have a different impact because they are consumed with dietary fiber, juices require caution. It's also important to remember that "sugar-free" beverages using artificial sweeteners, while low in calories, may perpetuate a preference for sweetness.
Practical Ideas for Reducing Sugar Intake
Simple Everyday Tips
- First, use the app to record "when, what, and how much" you drink for a week.
- Switch to unsweetened or lightly sweetened coffee and tea. Gradually reducing sugar makes it easier to stick with.
- Add lemon or mint to sparkling water, or make your own flavored water to feel satisfied.
- Even "health-conscious" commercial drinks can be high in sugar, so develop a habit of checking ingredient labels (for sugar, high-fructose corn syrup, etc.).
For Those Aiming for Ketosis
During ketosis, even a tiny amount of sugar can have an impact. From our experience, a single sugary drink can change blood sugar and ketone levels the next day, so it's safer to focus on sparkling water and unsweetened tea. If you absolutely crave a sweet drink, we recommend consuming it sparingly, considering the effects of artificial sweeteners and individual differences.
Conclusion
Apps like "Satou-san" are very useful for visually understanding the sugar content in soft drinks. We were also surprised by how much sugar is in the drinks we casually consume every day. The app is just a tool, so remember its limitations and the importance of checking labels. The goal is not to "rely entirely on the app," but to "develop a sense for sugar and change your daily choices." Just scanning what you usually drink for a week can lead to discoveries. As you continue, the amount and types of drinks you consume should naturally change.
