Data Visualization Project

Into food fads? Checked the facts?



Overview


Popular foods that once took Korea by storm — giant castella cakes 🍞 , brown sugar bubble tea 🥛 , and croffles 🥐 ...
Have you tried them all, following trends with friends? Many foods that Koreans eagerly embraced in line with trends are typically spicy, salty, or sweet. But have you ever seriously wondered, do these Instagram-worthy, delicious foods actually benefit my body?

To uncover the nutritional makeup of these trendy foods, we created a data visualization to see if following the trends might be leading to unintentional overconsumption of sugar, sodium, and other nutrients.

Process


1   Data Collection

What were some past food fads?

Based on a news article, survey results, and team discussions, we compiled the following list of 14 popular food fads in Korea.

Fat Macaron
 
Mala Soup
 
Buldak Spicy Noodles
 
Pyongyang Cold Noodles
 
So-tteok So-tteok
 
Honey Butter Chips
   
Myungrang Korean Hotdog
 
Brown Sugar Boba
 
Turtle Chips
 
Tanghulu
 
Giant Castella Cake
 
Rosé Tteokbokki
 
Croffle
 
Taiwanese Sandwich


What characteristics of these foods should we examine?

Easily noticeable characteristics  

  • Taste
  • Number of accumulated Instagram posts (popularity)
  • Grams per serving

Less noticeable characteristics  

  • Calories per serving
  • Nutritional content
    Sugar, sodium, fat, and cholesterol

Why these four?

... because these are nutrients that can cause issues when consumed in excess!

Where should we collect the data from?

1. Nutritional information for each food item

2. The taste of each food item

  • Collected opinions from various people through a online survey



2   Data Refinement

On the nutrition labels commonly found on snack packages, both per serving size and total serving size are listed, with nutritional values provided for each. However, sometimes the serving size is smaller than expected, or the total serving size is based on two servings. For this reason, we aim to present the calories and nutrients based on a single serving size. For smaller snack packages, the total amount is considered as one serving.

Additionally, using the daily nutritional reference values provided by the Enforcement Rule of the Act on Labeling and Advertising of Foods, we calculated the percentage (%) of each nutrient in relation to the daily recommended intake.

3   Visualization Ideation

We symbolized information about food fads as flowers.

Noticeable characteristics—taste, number of Instagram posts, and grams per serving—are represented by petals and stems, while less noticeable attributes—calories per serving and nutritional content—are represented as roots beneath the ground.

How to read

01
The size of the petals represents the intensity of flavors.
Based on the results of a preliminary survey, we categorized the four flavors—spiciness, sweetness, saltiness, and umami—into three levels. A flavor is represented at the largest level, level 3, if it is strongest, and level 0 if it is undetectable. The size of the petals varies proportionally with the intensity level.

02

The red circle surrounding the petals indicates the total number of Instagram posts related to each food, symbolizing the scent of the flower.

03
The length of the flower’s stem corresponds to the grams per serving of the food, while the length of the root directly beneath the stem reflects calories per serving.
This allows for a quick comparison of the quantity and calorie content.
How many calories are in the portion sizes of the foods you frequently eat?

04
Finally, the granules at the ends of the roots represent the amount of key nutrients as a percentage of the daily recommended intake, in the order of sugar, sodium, cholesterol, and fat.
A large granule indicates 10% of the daily recommendation, and a small granule represents 1%.
When you consume these foods, how much of the daily recommended amount are you actually taking in? Are there any foods that exceed the daily recommendation?

Insights

01
Honey Butter Chips might seem sweeter than Buldak Spicy Noodles, but they actually contain less sugar.

02
A single So-tteok So-tteok contains more fat than one serving of Rosé Tteokbokki.

03
One serving of Buldak Spicy Noodles and one serving of So-tteok So-tteok have the same calories (425 kcal).

04
The most popular item was the Fat Macaron, but recently Mala Soup and Croffles have been quickly catching up (in number of Instagram hashtags).

05
Foods high in calories per gram include Honey Butter Chips, Turtle Chips Choco Churros Flavor, and Fat Macaron. Foods low in calories per gram, due to high water content, include Brown Sugar Bubble Tea, Pyongyang Cold Noodles, and Mala Soup.


Additional Poster

One-Day Diet of Food Fads

For breakfast, a buttery croffle; for lunch, refreshing Pyongyang cold noodles; for dinner, spicy mala soup; with a sweet fat macaron as a snack and Buldak spicy noodles for a late-night craving. If you ate these trending foods for all three meals in a day, how much sugar, sodium, cholesterol, and fat would you consume?


The granules spilling from the cracks in the pot represent the excess percentages of nutrients beyond the daily recommended intake. Sodium exceeds the recommended amount by 191% and fat by 79%.
In other words, if you base your meals solely on trending foods, you may end up unintentionally consuming excessive amounts of certain nutrients.

Retrospective


Throughout the Spring 2021 semester, we held countless Zoom meetings due to COVID-19.
Using Zoom’s user reports, we visualized our total meeting time on Zoom!


Looking back on our team project through this visualization...

01
Among the four stages—topic selection, data collection, data cleaning, and data visualization—the stage that took the most time was, unsurprisingly, data visualization.  iterate, iterate, iterate ...

02
Data collection and data cleaning were often conducted in parallel with other stages.
For example, while collecting data, we also considered possible visualization approaches for the dataset.

03
The stages that caused us the most headaches were data visualization and data collection.
For data visualization, we spent a lot of time deciding on the concept and what elements to visualize, and defining the visualization grammar was challenging.
For data collection, it was remarkably difficult to gather nutritional information for certain foods, as many sources didn’t provide these details.

Takeaways


This project allowed me to channel my creativity and love for design, making it an enjoyable experience from start to finish. By collecting and analyzing data to create a poster on a single theme, I explored designing original visualization rules, which sparked my interest in pursuing more data visualization projects in the future.

Additionally, the process inspired me to consider evolving this concept into an interactive website, further expanding its potential to engage users and present data in a dynamic, immersive way.
