Korean Healthy Food: Korean Healing Foods and What Science Says

Korean home cooking centers on rice, soup and many small side dishes (banchan), most of them vegetables, plus tofu, fish and fermented foods such as kimchi. This World Healing Foods guide covers a Korean healthy food list and what research says. This page describes traditional foods and what research says about them. Foods support an overall healthy pattern; they do not treat any disease.

Food culture at a glance

A typical meal pairs mixed-grain rice and a soup or stew with several vegetable banchan. Many dishes, though, get their flavor from salty fermented pastes and sauces.

Top healing foods and what research says

Evidence notes

• Kimchi and fermented foods: fermented foods can contain live microbes, but NIH notes probiotic benefits are strain-specific and not established for most uses. (NIH NCCIH)
• Soy: soy protein in place of other proteins may lower cholesterol to a small extent. (NIH NCCIH)
• Fish: mackerel and other fatty fish provide EPA and DHA omega-3s. (NIH ODS)
• Garlic: Garlic supplements may lower total and LDL cholesterol to a small extent in people with high cholesterol; research has mostly tested supplements, not garlic in food. (NIH NCCIH)

Signature healthy dishes

• Bibimbap with lots of vegetables, an egg and a small amount of gochujang
• Doenjang jjigae (soybean paste stew) with tofu and vegetables, light on paste
• Grilled mackerel with mixed-grain rice and namul
• Miyeok guk (seaweed soup), low salt
• Ssam: lettuce wraps with grilled fish or tofu

Watch-outs: sodium

• Kimchi, gochujang and doenjang are salty and may add a lot of sodium. USDA data list about 750 mg of sodium in one cup (150 g) of kimchi (about 498 mg per 100 g; FDC ID 170392) (USDA FoodData Central). One brand of soybean paste (doenjang) lists about 580 mg in a 12-gram serving (about 4,830 mg per 100 g; FDC ID 391944) (USDA FoodData Central). One brand of gochujang sauce lists about 290 mg in a 2-tablespoon serving (FDC ID 2244609), and one brand of gochujang lists about 2,750 mg per 100 g (FDC ID 2410981) (USDA FoodData Central); values vary, so check labels.
• WHO advises adults keep sodium under 2,000 mg a day; high sodium raises blood pressure. (WHO)
• Seaweed is rich in iodine, and too much iodine can cause thyroid problems. (NIH ODS)

How to try it

• Serve kimchi as a small side rather than a main portion, and rinse or choose lower-salt versions
• Swap half the white rice for barley or mixed grains
• Fill half the table with namul and fresh vegetables

Kimchi is a fermented food that can contain live microbes, but NIH notes probiotic benefits depend on the strain and are not proven for most uses. It is also salty and may add a lot of sodium (USDA FoodData Central lists about 498 mg per 100 g), so keep portions small. (NIH NCCIH) (USDA FoodData Central)

What are the healthiest Korean dishes?

Vegetable-rich bibimbap, tofu and vegetable stews, grilled fish with mixed-grain rice, and namul are good choices, with sauces and pastes used lightly. (Mayo Clinic)

Is gochujang high in sodium?

It can be. One brand of gochujang sauce in USDA FoodData Central lists about 290 mg of sodium per 2-tablespoon serving, and one brand of gochujang lists about 2,750 mg per 100 g; values vary, so check labels. WHO recommends adults keep sodium under 2,000 mg a day. (USDA FoodData Central) (WHO)

Is seaweed soup (miyeokguk) good for you?

Seaweed such as miyeok is rich in iodine, which the body needs, but too much iodine may cause thyroid problems, so enjoy seaweed in normal food amounts. (NIH ODS)

Is tofu a healthy protein choice?

Tofu is made from soy, and NIH notes that eating soy protein in place of other proteins may lower cholesterol levels to a small extent. (NIH NCCIH)

How can I make Korean meals lower in sodium?

Use smaller amounts of kimchi, soy sauce, gochujang and doenjang, and fill up on namul and fresh vegetables. Mayo Clinic advises limiting salty condiments and using herbs and spices for flavor, which may support lower sodium intake. (Mayo Clinic)
