Honestly, if you ask ten different people which country has the healthiest food, you’re going to get ten different answers. One person will swear by the olive oil in Italy. Another will tell you that the secret to a long life is buried in a bowl of Japanese miso.
But here’s the thing. "Healthy" isn't just about one superfood. It's about the entire ecosystem of what people put on their plates every single day for decades.
The 2026 Verdict: Spain and Italy Are Still Squabbling for the Top Spot
If we look at the latest Bloomberg Global Health Index data and the most recent 2025-2026 rankings, Spain and Italy are basically the heavyweights in the ring. They consistently trade the number one spot. Why? It’s the Mediterranean diet. It’s almost a cliche at this point, but the science doesn't lie.
People in these countries don't just "eat healthy." They live it.
You've got high intakes of extra virgin olive oil, which is basically liquid gold for your arteries. Then there's the massive amounts of legumes—chickpeas, lentils, beans—that provide fiber most Americans can only dream of. They eat meat, sure, but it’s often a side dish or a flavoring, not a 16-ounce slab of steak sitting in the middle of the plate.

Recent studies from the University of Navarra in Spain have reinforced that this specific way of eating—high in monounsaturated fats and antioxidants—is why Spain often holds the crown for the world's healthiest nation.
Japan: The Longevity Outlier
Then there’s Japan. If you’re measuring health by how long you actually stay on this planet, Japan often wins. They have one of the highest life expectancies globally.
The Japanese diet—Washoku—is a masterclass in "less is more."
- Seaweed: Packed with iodine and minerals you barely find in land plants.
- Fermented Foods: Miso and natto do wonders for the gut microbiome.
- Small Portions: They have a saying, Hara Hachi Bu, which basically means eat until you're 80% full.
It’s a different kind of healthy than the Mediterranean style. It’s lower in fat and much higher in iodine and specific probiotics. But, interestingly, 2026 data shows Japan is struggling slightly with a "nutrition transition" as younger generations lean toward Western-style fast food. It's a reminder that even the healthiest food cultures can be fragile.

The Underdogs: Iceland and South Korea
You don't hear about Iceland much in food conversations, but maybe we should. Their diet is incredibly clean. We're talking fresh-caught cold-water fish like salmon and cod, which are loaded with Omega-3s. They also have skyr, a fermented dairy product that’s basically Greek yogurt’s more powerful cousin. Because the environment is so harsh, their produce is often grown in geothermal greenhouses, meaning it's remarkably free of pesticides.
And then there's South Korea.
Koreans are the undisputed kings of fermentation. Kimchi isn't just a side dish; it’s a lifestyle. The sheer variety of vegetables consumed in a typical Korean meal—often 5 to 10 different types of banchan (side dishes)—puts most salads to shame.
What Most People Get Wrong About "Healthiest" Food
A common mistake is thinking that if you just buy some Italian olive oil, you’re suddenly eating the world’s healthiest diet.
It doesn't work that way.

The real reason these countries rank so high is the absence of ultra-processed junk. In the US, the USDA recently underwent a massive policy shift in early 2026, with leaders like Robert F. Kennedy Jr. pushing for a "return to basics." The goal is to mimic what these other countries do naturally: eat whole, nutrient-dense foods and cut the synthetic dyes and artificial additives.
The "healthiest" food isn't a specific recipe. It's a lack of processing.
The Surprising Metric: Taiwan and Singapore
If we look at the CEOWORLD 2025-2026 Global Health Index, Taiwan and Singapore have actually shot up to the very top.
This is fascinating because their diets are a mix of traditional Asian staples and highly regulated modern nutrition. In Singapore, the government actually incentivizes hawker stalls to use healthier oils and whole grains. It’s a top-down approach to healthy eating that’s actually working. They focus heavily on steamed fish, leafy greens (like bok choy and choy sum), and tropical fruits that are rich in Vitamin C.
Actionable Steps to Eat Like the World's Healthiest
You don't have to move to Madrid or Tokyo to fix your diet. You can steal their best moves right now.
- Switch your primary fat. If it’s not Extra Virgin Olive Oil, why? Use it for dressings and low-heat cooking.
- Add a fermented "funk." Start including a tablespoon of kimchi, sauerkraut, or a bowl of miso soup a few times a week. Your gut bacteria will thank you.
- The "Meat as a Garnish" Rule. Try to make vegetables or legumes the star of the show. Use meat for flavor rather than volume.
- Embrace the Frozen North. Don't sleep on frozen wild-caught fish. It’s often just as nutritious as the fresh stuff found in Iceland but way more affordable.
- Watch the Salt. This is the one area where Japan and Korea struggle. If you're eating fermented foods, you're getting plenty of sodium, so don't over-salt your other dishes.
Health isn't a destination; it's the stuff you do when nobody is watching. It's the beans in your pantry and the oil in your pan. Whether you follow the Spanish model or the Japanese one, the secret is simply getting back to real, recognizable food.
