It was a scene I witnessed last week at a Whole Foods near Times Square in New York City. Westerners were lined up in front of the Korean kimchi section, and an employee was holding up a sign that read "Sorry, sold out again." This was no coincidence.
South Korea's seaweed exports hit another record high in 2024, reaching $997 million. That's almost double the $500 million just five years ago. Behind the numbers is the love of consumers around the world.
A complete breakdown of the global seaweed craze: In this article, we analyze how Korean nori has captured the hearts of Westerners through on-the-ground stories. From Walmart in New York to Tesco in London, we cover the global nori battle, how it was recognized as a superfood, and its potential to break the $1 billion mark. Everything a global audience wants to know about nori, all in one place.
1. The Korean Kim that the world is talking about - the secret behind the $9.97 billion record

South Korean seaweed exports hit a record $997 million in 2024, and international media took notice. CNN reported on the phenomenon with the headline "Korean Seaweed Breaks Records Again," and the BBC described it as "The Black Paper Taking Over Western Plates."
What makes this number so amazing is the rate of growth: from $543 million in 2020, seaweed exports have nearly doubled in just four years. Even when the global economy was struggling, nori was an exception.
🌍 The people behind the global seaweed craze:
- U.S. millennials' preference for healthy snacks
- European vegan community turns to B12 as a source of vitamin B12
- Spreading demand from growing Asian immigration
- What Social Media Influencers Say About the Kim Diet
Of particular note is that the 2024 growth in seaweed exports is not just quantitative: while Asian consumers have been the primary customers in the past, consumers of all ethnicities are now buying seaweed, including Caucasians, Hispanics, and Blacks.

2. What's steaming? The black paper the West is addicted to

"It looks like black paper, but tastes like the ocean with a hint of salt." This was Sarah Johnson's (28) first impression of nori when I met her in New York City. At first, I thought it looked weird. But after tasting it once, she says she eats nori on her lunch salad every day.
Nori (Seaweed or Nori) is a traditional Korean food made from thinly dried seaweed that grows in the sea. To Westerners, it's called "edible paper" or "sea vegetable". In recent years, it has even earned the nickname "Korean superfood".
🤔 Kim vs Japanese Nori, what's the difference?
It's a question many Westerners ask: It's basically the same algae. Korean nori is characterized by being seasoned with sesame oil and salt. Japanese nori is usually unsalted or very mild in flavor. Korean nori has a strong savory and salty flavor, making it a great snack.
One of the reasons Westerners are so obsessed with nori is its unique flavor. It has a strong umami flavor called "umami". Many foreigners testify that once they try it, they keep coming back for more. Its crunchy texture has also made it a popular healthy snack alternative to potato chips.
Features | Korea Kim | Nori, Japan | Westerner preference |
---|---|---|---|
Flavors | Savory and salty | Light and mild | Kim |
Texture | Crispy | Smoothness | Kim |
Purpose | For snacking + cooking | Mainly for sushi | Kim |
Pricing | $2-4/pack | $3-6/pack | Kim |
According to a K-Mart employee who sells Korean seaweed in London, the number one question customers ask is, "How do I eat this?" You can just tear it open and eat it. You can put it on a salad. When you explain that you can eat it with rice, they're usually surprised.

3. The Superfood Craze: Le Po - The Nori Wars from New York to London
It's 10 a.m. at a Whole Foods store in Brooklyn, New York. The scene in front of the Korean seaweed section is remarkable. A white housewife is loading a 10-pack of nori into her cart. A Hispanic young man is perusing the nutrition label on the nori. A black fitness instructor is asking an associate, "Is this really only 10 calories?"
This isn't just a New York phenomenon - it's similar in the K-food section of Tesco in London. A similar scene is playing out in the Asian food section of Monopoly in Paris. Nori has become more than just an "Asian food", it's a "global superfood".
🏪 Global nori sales field report:
United States: Officially available at Walmart, Whole Foods, and Trader Joe's
United Kingdom: Tesco to launch K-food corner in Sainsbury's
Germany: Lidl, Aldi test sell seaweed products at Aldi
France: Carrefour sells premium seaweed at Monopoly
Nori has exploded in popularity, especially with the increased focus on health since COVID-19. The US FDA's classification of nori as a "low-calorie, high-nutrient food" has also had a big impact. A single sheet of nori has just 5 calories. It's rich in iodine and vitamin K, making it the "perfect diet snack.
⚠️ Caution: The high iodine content of nori may affect thyroid function, so if you have a thyroid condition, please consult your healthcare provider before consuming.

David Kim, a London-based seaweed importer, says his business is growing. "Since 2021, orders have been increasing by more than 301 tons per year," he says, "with female customers in their 20s and 40s accounting for 601 tons." They buy nori primarily for diet and health purposes.
"When I first started eating nori, it was weird," says Claire Dupont, 32, a yoga instructor from France, whom I met in Paris. "The first time I ate nori, it was weird," she says, "but now I eat it at least once a day." "I've lost weight and my skin has improved," she says. "I've lost weight and my skin has improved since I started eating nori instead of potato chips." As testimonials like these spread across social media, the popularity of nori is spreading.
4. The Miracle of K-Dramas - Kim Goes Viral from Netflix to TikTok

When "The Squid Game" became a global phenomenon in 2021, one surprising thing happened. International audiences, inspired by the drama's seaweed scenes, began to seek out Korean seaweed, says the president of K-Mart in New York. "After the show aired, our nori sales increased by 3001 TP3T."
Netflix hasn't missed the trend, producing a series of Korean food documentaries, including A Nation of Kimchi and A Nation of Banchan, which showcase the intimate details of how seaweed and kimbap are made. It was a breath of fresh air for Western audiences.
📺 K-Content Kim viral timeline:
2020: 'Kingdom' drama's kimbap scene is the talk of the town

5. Why nutritionists are taking notice - nori vs kale, the real winner?

When we think of "superfoods" in the West, kale is the first vegetable that comes to mind. But there's a growing consensus among nutritionists that nori may be able to surpass kale. According to nutrition researchers at Harvard Medical School. "The nutrient density of nori is much higher than kale."
Nutrients (per 100 grams) | Nori (Korean Seaweed) | Kale | Winner |
---|---|---|---|
Calories | 35 kcal | 49 kcal | Kim |
Iodine | 2,984 μg | 2 μg | Kim |
Vitamin K | 66 μg | 704 μg | Kale |
Vitamin C | 39 mg | 120 mg | Kale |
Vitamin B12 | 2.4 μg | 0 μg | Kim |
Nori is a revolutionary food, especially for vegans. Vitamin B12 is usually only found in animal products. However, nori contains ample amounts of B12. This is great news for the 50 million vegans in the world.
⚠️ Caution: The high iodine content of nori may affect thyroid function. If you have a thyroid condition, please consult your healthcare practitioner before consumption. The nutrition information in this article is for general reference only. Please prioritize professional advice based on your individual health needs.
"It's the sea's multivitamin," says London-based nutritionist Dr. James Wilson. "Nori is the multivitamin of the sea," he says, "and it's an easy way to replenish iodine, which is particularly lacking in the modern diet." However, he cautions against overconsumption.
6. The Billion Dollar Scenario - Will Nori Unseat Avocado?

After reaching $9.97 billion in seaweed exports in 2024, the industry is confident of breaking the $1 billion mark in 2025. It's not just a number - $1 billion is the threshold for being recognized as a 'major player' in the global food market.
Avocados are a good comparison. In 2015, the global market for avocados was $400 million, but it grew to a $13 billion market by 2024, riding the healthy eating trend among millennials. Nori is likely to follow a similar trajectory.
🚀 Kim's billion-dollar scenario:
Projected to 2025: 10.5B (5% growth)
2026 goal: 1.2 billion (new markets)
Looking ahead to 2027: 1.5 billion (product diversification)
Vision 2030: 2 billion (Global Standard)
Of particular note is the proliferation of new markets. Currently, seaweed is exported to 122 countries. However, the African and South American markets are still in their infancy. As the popularity of K-content spreads in these regions, the demand for nori is expected to increase.
Product diversification is also a growth driver. Currently, seasoned nori is the mainstay, but new products such as nori powder, nori oil, and nori snack bars are being developed. This will transform nori from just an 'Asian food' to a 'global ingredient'.
South Korea's Ministry of Oceans and Fisheries aims to reach $2 billion in seaweed exports by 2030. To that end, it is working on branding the product as 'K-Gim'. Globally, there is also an ongoing effort to get people to refer to nori as 'Gim' instead of 'Nori'.
Conclusion
Nori exports reaching a new record of $9.97 billion in 2024 is more than just a number - it's proof that consumers around the world are enamored with South Korea's sea vegetable. It's no longer surprising to see nori sell out at Whole Foods in New York.
The cultural ripples created by K-dramas and Netflix are here to stay. Kim is becoming more than just an export, it's becoming a symbol of Korean culture. Breaking the $1 billion mark in 2025 is just the beginning.
