Americans are so adventurous when it comes to food—you’ll try new trends, hunt down authentic flavors, and pay top dollar for global fusions. But despite that curiosity, there’s a long list of ingredients eaten daily around the world that rarely make it to American plates. Some are full of nutrients, others are centuries-old staples, yet many remain unfamiliar due to a lack of exposure, cultural preferences, or simply how different they seem from common Western foods. Here’s a closer look at 20 essential foods that are deeply rooted in global cuisines but often underused in the American kitchen. You probably won’t see them in your average grocery cart, but they shape meals across Asia, Africa, Latin America, and beyond. Their absence has little to do with quality—it’s more about habit, access, and exposure. If you’re looking to understand what much of the world eats on a daily basis, this list is a smart place to start.

Millet

Grown and eaten across much of Africa and South Asia, millet is a drought-resistant grain with high versatility and nutritional value. It’s naturally gluten-free, quick to cook, and works well in both sweet and savory dishes like porridges or pilafs. In India, it’s a staple in flatbreads, while in parts of Africa, it’s used for fermented drinks or thick porridge. Despite these uses, millet hasn’t found wide adoption in American households, likely because rice and wheat dominate the grain market. Many also associate it with birdseed, further distancing it from everyday U.S. meals.

Plantains

Ubiquitous in Latin American, Caribbean, and West African cooking, plantains are a starchy cousin of bananas that serve as a major carbohydrate source. You can eat them green and savory—like in tostones or mofongo—or ripe and sweet, often fried. Their adaptability makes them an everyday staple in many tropical regions. In the U.S., though, plantains are often misunderstood or seen only as a novelty, not a pantry basic. They’re typically found in specialty sections, which limits their exposure to American cooks.

Red Lentils

Red lentils are a fundamental part of Indian, Middle Eastern, and North African cuisines, especially in hearty soups and stews like dal. They cook quickly—often in 15–20 minutes—breaking down into a creamy texture that doesn’t require blending. Unlike green or brown lentils, they don’t retain their shape, making them perfect for thickening dishes. In the U.S., red lentils are overshadowed by canned beans or other lentil varieties and remain underutilized despite their convenience. Their muted visibility is also due to unfamiliarity with traditional recipes that use them.

Amaranth

Amaranth is a nutrient-rich grain historically cultivated by the Aztecs and still popular in Mexico, Peru, and parts of India. It’s high in protein, including lysine—an amino acid not found in many grains—and can be puffed, boiled, or ground into flour. You’ll find it in traditional sweets like Mexican alegrías or as porridge across South America. Its unfamiliar texture and lack of mainstream branding in the U.S. have kept it from gaining traction. Many Americans overlook it in favor of more popular grains like quinoa or oats.

Cassava (Yuca)

Cassava is a hardy root vegetable that forms the dietary backbone for millions across Africa, the Caribbean, and South America. It can be boiled, fried into crispy chips, or mashed like potatoes, and it’s also the source of tapioca. With a mild, slightly nutty flavor, cassava is a reliable energy source, especially in regions with limited grain access. In the U.S., it’s still seen as exotic and rarely cooked at home, in part because it requires proper preparation to remove natural toxins. Most people also don’t realize how many global comfort foods are built around cassava.

Kefir

Kefir is a fermented dairy drink consumed widely in Eastern Europe, the Caucasus, and Central Asia, prized for its gut-friendly probiotics and tangy flavor. It’s made using kefir grains that ferment milk into a drinkable yogurt-like product with a slightly fizzy texture. Compared to yogurt, kefir contains a broader range of beneficial bacteria and yeast. While available in U.S. stores, it’s still considered niche and is often limited to the health-conscious or probiotic-focused audience. Many avoid it due to its tart flavor or unfamiliar texture, despite its long-standing global use.

Sorghum

Grown in India, Africa, and parts of the Middle East, sorghum is a drought-tolerant grain used in porridge, flatbreads, and even beer. It’s high in fiber, naturally gluten-free, and can be popped like popcorn or ground into flour for baking. In the U.S., sorghum syrup was once common in Southern cooking, but the grain itself never reached mainstream appeal. Today, it’s mostly seen in health food aisles or gluten-free recipes, far from its daily use abroad. Limited awareness and competition from other ancient grains contribute to its underuse.

Seaweed

Essential in Japanese, Korean, and coastal Chinese diets, seaweed provides iodine, fiber, and a distinct umami punch. It’s used in soups, rice dishes, snacks, and even salads, showcasing its variety beyond sushi rolls. Edible types like nori, kombu, and wakame serve specific culinary roles in East Asia. In American kitchens, however, seaweed is rarely explored beyond sushi restaurants or snack packs. The oceanic flavor profile and lack of familiarity in Western cooking techniques keep it from wider use.

Black Sesame Seeds

Black sesame seeds are integral to many East Asian desserts and sauces, especially in Japan, China, and Korea. Their deep, toasty flavor stands out more than white sesame, which is often used in pastes, ice creams, or sweet buns. The seeds are also rich in calcium, iron, and healthy fats. Despite their presence in some Asian-American bakeries, black sesame remains rare in broader U.S. home cooking. Most people stick with white sesame seeds, missing out on the richer flavor and nutritional profile.

Kimchi

Kimchi is a staple Korean dish made by fermenting napa cabbage and radishes with chili, garlic, ginger, and salt. Packed with probiotics, it’s eaten daily in Korean households—often served with every meal. The sharp, spicy, and sour profile gives it a punch that many Western palates are still adjusting to. Though its popularity is rising in urban food scenes, kimchi is still not a common item in most American fridges. Many avoid it due to its strong smell, fermentation, or simply unfamiliarity.

Bitter Melon

Widely used in Indian and Southeast Asian cooking, bitter melon is a green, bumpy gourd known for its medicinal benefits, such as blood sugar control. It’s often stir-fried, stuffed, or cooked in curries to mellow its intense bitterness. Despite being part of traditional healing systems like Ayurveda and Traditional Chinese Medicine, it remains off-putting to many unfamiliar with its taste. In the U.S., bitter melon is rarely seen outside of Asian markets. Its acquired bitterness and lack of mainstream recipes have kept it from becoming common.

Teff

Native to Ethiopia, teff is the main ingredient in injera, a sour, spongy flatbread served with nearly every Ethiopian meal. It’s high in fiber, iron, and protein, with a mild, earthy flavor. Teff flour also works in pancakes, breads, and porridges. Though gaining recognition in gluten-free circles, it remains largely unknown in mainstream American cooking. Limited availability and niche appeal have kept it from wider use outside of East African communities.

Jackfruit

Used widely in India, Bangladesh, and Southeast Asia, jackfruit can be cooked green as a meat substitute or eaten ripe as a sweet, tropical fruit. Its fibrous texture mimics pulled pork when unripe and is rich in vitamins and antioxidants. Street vendors across Asia sell it fresh, while home cooks braise or curry it. In the U.S., jackfruit gained some traction as a vegan meat alternative but hasn’t reached the status of tofu or tempeh. Its size, preparation needs, and short shelf life make it challenging for everyday use.

Mung Beans

Staples in Chinese soups, Indian dals, and Southeast Asian desserts, mung beans are small green legumes with a mild, slightly sweet taste. You’ll find them sprouted in stir-fries or boiled whole in stews and congee. High in protein, iron, and folate, they’re both affordable and versatile. In the U.S., mung beans are primarily sold in Asian markets, rarely crossing into mainstream cooking. Most American recipes don’t include them, which limits exposure and adoption.

Lotus Root

Known for its unique appearance and crisp texture, lotus root is used in Japanese tempura, Chinese soups, and Indian curries. It’s rich in fiber and vitamin C, and it holds up well to frying, boiling, or braising. The mildly sweet flavor and decorative holes make it popular in celebratory dishes across Asia. In America, lotus root is often viewed as exotic and found only in specialty grocers. Its unfamiliar look and preparation keep it off the radar for most home cooks.

Barley

Barley is a hearty grain used across Europe and the Middle East in soups, pilafs, and salads. Its chewy texture and nutty flavor work well in stews or as a rice alternative. Loaded with fiber and B vitamins, barley supports digestion and heart health. Despite being grown in the U.S., it’s often relegated to beer production rather than daily meals. Most American recipes lean on rice or pasta, leaving barley underutilized.

Tamarind

Tamarind is a tangy fruit pulp found in Asian, African, and Latin American sauces, candies, and drinks. It balances sweet, sour, and savory notes, making it key in dishes like pad Thai, Indian chutneys, and Mexican agua fresca. The pulp is packed with antioxidants and has a long shelf life when processed into paste or concentrate. In the U.S., tamarind often flies under the radar except in ethnic restaurants. Its intense tartness and unfamiliar usage make it less appealing to mainstream consumers.

Soursop (Graviola)

Soursop is a tropical fruit with soft, white pulp that blends well into juices, smoothies, and frozen desserts. Common in Caribbean, Central American, and Southeast Asian diets, it’s known for its sweet-tart flavor and creamy texture. Some cultures value it for supposed immune-boosting properties. Fresh soursop is difficult to find in most U.S. grocery stores due to its short shelf life and limited domestic production. Without easy access or broad awareness, it’s stayed mostly outside American food trends.

Ghee

Used daily in Indian households, ghee is clarified butter made by simmering and removing milk solids—resulting in a nutty, rich cooking fat. It’s shelf-stable, high in fat-soluble vitamins, and great for high-heat cooking. Ghee is central in Indian cuisine, from frying to tempering spices. Although more U.S. health stores now stock it, many Americans still shy away due to old misconceptions about saturated fat. Its deep flavor and traditional roots remain underexplored by most home cooks.

Fermented Soy Products (Like Natto or Tempeh)

Fermented soy is central to daily meals in countries like Japan and Indonesia, where natto and tempeh provide protein, probiotics, and deep flavor. Natto has a sticky texture and pungent smell, while tempeh offers a firmer, nuttier alternative to tofu. These products have been consumed for centuries and support gut health through natural fermentation. In the U.S., tofu is widely known, but its fermented cousins remain far less mainstream. Strong flavors, texture differences, and limited recipes keep them from broader acceptance.
