Blue zones do it better. After spending a month in a blue zone (i.e. areas of the world where people consistently live longer [1]), dietitian and content creator Maggie Hennigan [2] left feeling so good, she decided to start re-creating some of her favorite blue zone meals at home. Her main goal: "To make my life as much like a blue zone as possible," she shared in a 2024 TikTok [3]. "Obviously, that includes food."
Blue zones — including Nicoya, Costa Rica, which Hennigan visited — are major hubs for wellness and longevity. But the good news is, you don't have to live in an actual blue zone to re-create some of the most commonly consumed foods. In fact, many of the blue zone health benefits are attributed to specific diets, foods, and community practices.
Considering that the heritability of the human lifespan is only about 50 percent [4], Hennigan might be on to something with her blue zone meals. Registered dietitian Amanda Blechman agrees. "While there are a variety of factors that could contribute to the longer-than-average lifespan in these populations, the foods they eat could very well play a role in the longevity they enjoy," Blechman says. "In general, eating more plant-based and nutrient-dense foods like vegetables, fruits, whole grains, high-quality dairy products, and fortified soy milks can increase one's intake of nutrients that we often fall short on here in the US."
If you can't visit an actual blue zone, but still want to reap the longevity benefits, we rounded up some easy blue zone-inspired recipes to get you started. Read on for all the blue zone meal inspo, featuring tips from actual dietitians.

Where Are the Blue Zones?
Five of the most well-known blue zones include:
- Ikaria, Greece
- Loma Linda, California
- Sardinia, Italy
- Okinawa, Japan
- Nicoya, Costa Rica
What Are Blue Zone Foods?
The exact ingredients vary based on location, but generally speaking, blue zones do share some dietary similarities. "While each blue zone has its own traditions and ways of preparing food, all follow a predominantly plant-based eating pattern that emphasizes foods like beans, whole grains, vegetables, fruits and nuts," Blechman says. Expect to see colorful plates filled with nutrient-dense foods like dark leafy greens, berries, and legumes like beans, chickpeas, and lentils, says Wendimere Reilly, RDN, LDN.
Whole grains (including oats, barley, quinoa, and brown rice) are also blue zone staples, along with several types of nuts and seeds. "Flavor is enhanced from olive oil, herbs, and spices such as turmeric, cinnamon, oregano, cumin, rosemary, and thyme," Reilly says. Animal-based foods like eggs, fish, and fermented dairy products like kefir and yogurt complement the rest of the diet.
It comes as no surprise that the blue zone drink of choice is water. That said, beverages like coffee, tea, and red wine are also enjoyed in blue zones.
What Foods Do Blue Zones Avoid?
Moderate consumption is key, especially when it comes to meat. Blechman notes that most blue zones limit their meat intake to small servings five times a month. "That's a lot less than we tend to consume as part of the average American diet," she says. "They also tend to consume significantly less added sugar than most Americans, though they don't eliminate it completely and include it mindfully into their day."
Blue Zone Meal Benefits
There's plenty of benefits to blue zone eating, including blood sugar management [8], reduced risk of type 2 diabetes [9], better sleep quality [10], and reduced inflammation [11]. Here are some other compelling perks:
- Diverse nutrients: Blechman says common blue zone foods have nutrients people in the US are often missing. These include fiber, calcium, vitamin D, and potassium.
- Better heart health: Basic blue zone foods like fruits, vegetables, nuts, and soy can promote better heart health (which is great for longevity).
- Improved gut health: A 2022 study [12] published in The American Journal of Clinical Nutrition found that the flexitarian diet embraced by many of the blue zones (plant-based with animal products in moderation) was associated with higher gut microbiome diversity, Blechman says. According to Reilly, fermented foods like sourdough, sauerkraut, kimchi, and yogurt may also be to thank for these findings. Better gut health [13] can contribute to better digestion, increased immunity, reduced inflammation, and even improved mood.
- Improved metabolic health: Blue zone ingredients can help supply our cells with energy, Reilly says. That can make it easier for your body to convert food into energy, promoting better metabolic health.
While blue zone eating is generally considered safe for most people, watch for deficiencies [14] in vitamin B12, zinc, and calcium. People with digestive issues like IBS may also find the transition more difficult, so make sure to consult your healthcare provider before making any major changes to your diet.
Tips For Blue Zone Eating
If you want to turn your kitchen into a mini blue zone, our experts have some suggestions.
- Start small: "A simple way to begin is by dedicating one day per week to plant-based eating and gradually transitioning animal proteins to smaller side portions during the rest of the week," Reilly says.
- Add to your plate: "Focus on nutritious foods to add as opposed to foods to avoid," Blechman says. "Beans are huge in the blue zones, so making them a staple in some of your go-to recipes can be a good place to start adding a little blue zone inspiration."
- Eat with your community: To really embrace the blue zone ethos, Blechman encourages you to share meals with friends and family. "Celebrating connection and the joy of delicious food is a cornerstone of the blue zone lifestyle," she says.
Some of Blechman's favorite ideas include swapping kidney beans for meat in chili, adding chickpeas to your salad, or making a three-bean salsa dip. For fruits and veggies, she suggests making a smoothie to quickly pack in more nutrition. "I like to make mine with frozen fruit, some kind of green veggie . . . and soy milk for a plant-based source of complete protein," she says.
Blue zone snacks might include nuts and a fermented dairy product like yogurt (or a plant-based alternative). Just remember that "blue zone eating is a lifestyle not a diet," Reilly says. "Choose more plant based whole foods, less ultra-processed foods and added sugars. The goal is delicious, nutritious and most importantly, sustainable."
