Vietnamese cuisine has garnered global acclaim for its irresistible flavors. However, the question remains: is Vietnamese food truly healthy? While some dishes, particularly those that are fried, may contain higher levels of fat, Vietnamese cuisine is largely considered one of the healthiest and most balanced in the world. This article explores the various facets of Vietnamese food, examining its ingredients, cooking methods, and nutritional benefits to determine its overall healthfulness.
Understanding Vietnamese Cuisine
Vietnamese cuisine is a harmonious blend of five distinct tastes: sweet, salty, bitter, sour, and spicy. It often utilizes rice noodles, paper, and flour, and is generally low in sugar and gluten-free. Key ingredients such as lemongrass, ginger, mint, long coriander, Saigon cinnamon, bird's eye chili, lime, and Thai basil leaves contribute to its unique flavor profile. The cuisine's popularity stems from its diverse, delicate, and distinctive dishes, often utilizing local specialties. Vietnam has even been ranked among the top countries with the best food.
Vietnamese cuisine incorporates the Chinese-derived cosmological principles of Am and Duong (yin and yang) and ngu hanh (the five elements). The am principle promotes balance between yin (feminine energy) and yang (male energy). This is reflected in the combination of white rice with colourful, savory side dishes. The cold-hot paradigm is also applied, with certain ingredients having heating or cooling influences.
The five elements theory (water, fire, wood, metal, and earth) influences culinary choices as well. Rice represents earth, soup represents water, greens represent wood, fish sauce represents fire, and dry dishes represent metal. This theory extends to the five basic cooking modes: raw, steamed, boiled, fried/grilled, and fermented, and even to the five textures: crispy, crunchy, chewy, soft, and silky.
Why Vietnamese Food is Generally Healthy
Vietnamese cuisine is considered a healthy and green option, often compared to the Mediterranean diet. Its health benefits stem from:

- Fresh Ingredients: Vietnamese dishes emphasize the use of fresh, locally sourced ingredients, including an abundance of herbs and vegetables.
- Minimal Cooking: Many dishes involve minimal cooking, which helps retain the nutrients in the ingredients.
- Leafy Greens: Leafy green vegetables are a cornerstone of Vietnamese cuisine, providing essential vitamins, minerals, and fiber.
- Fish and Seafood: Fish, tofu, and legumes are favored over red meat, reducing the intake of saturated fats.
- Low Fat: Vietnamese cooking methods typically involve boiling, steaming, stewing, and braising, minimizing the use of oil.
- Moderate Sugar Use: Palm sugar, which has a lower glycemic index than refined sugar, is often used in desserts.
Consuming less meat also reduces environmental impact, as the production of one meat calorie requires significantly more resources than the production of vegetal calories.
The Prominence of Leafy Green Vegetables
Leafy green vegetables are highly valued in Vietnamese cuisine for their nutritional value and taste. Vegetables like Malabar spinach, rau muống (water spinach or swamp cabbage), bok choy, lettuce, and cabbage are commonly included in meals from breakfast to dinner. Their prominence contributes significantly to the health benefits of Vietnamese food. Rau muống, for example, is rich in vitamin A, iron, and fiber. Other herbs like cilantro, Thai basil, perilla, and mint are also eaten fresh and in abundance.
Low-Fat Cooking Methods
Compared to Western and Chinese dishes, Vietnamese cuisine generally has a lower fat content. While Chinese dishes often involve generous amounts of oil, Vietnamese food relies more on boiling, steaming, stewing, and braising. This limits the quantity of oil and fat in each dish, making greasy dishes relatively rare.
Low-Fat Seasoning Methods
Vietnamese cuisine uses low-calorie condiments like fish sauce and lemongrass to add flavor without additional calories. Nước mắm (fish sauce), made from fermented anchovies and salt, enhances the sweetness and saltiness of dishes. Each dish often has a unique dipping sauce, typically containing lime juice, sugar, chili, and garlic, considered the soul of the dish.
Key Components of a Healthy Vietnamese Diet
Rice: The Staple Carbohydrate
Rice is the staple carbohydrate in Vietnam, consumed in various forms-steamed, puffed, rolled, or made into noodles and paper wrappers.

Protein Sources: Fish, Tofu, and Legumes
Vietnamese cuisine relies more on fish, tofu, and legumes than on red meat. Cá kho tộ, braised fish cooked in a clay pot with caramelized sauce, is a popular dish. Tofu (đậu hũ) is often fried, steamed, or simmered in tomato sauce. Shrimp and shellfish are also frequently used in soups, rolls, and stir-fries.
Soups: A Central Role
Soups play a central role in Vietnamese cuisine, often warm, light, and easy to digest. Phở, a slow-cooked beef or chicken noodle soup seasoned with star anise, cinnamon, and cloves, is a national favorite. Canh chua, a sour soup made with tamarind, pineapple, tomatoes, and fish, is another popular choice.
Fermented Foods: Essential for Longevity
Fermented foods are integral to the Vietnamese diet. Nước mắm (fish sauce) is a fermented condiment made from anchovies and salt.
Drinks: Healthy and Diverse
Vietnamese cuisine includes a variety of healthy and flavorful drinks:
- Green Tea: A staple in Vietnamese culture, green tea is rich in antioxidants and is known for its numerous health benefits.
- Sinh Tố Bơ (Avocado Smoothie): A creamy blend of ripe avocados, milk, and a hint of sweetness, packed with healthy fats and nutrients.
- Jackfruit Drinks: Jackfruit is a tropical fruit known for its sweet flavor and high vitamin content, often used in refreshing beverages.
- Tra Sua (Milk Tea): A popular drink combining black tea with brown sugar syrup and milk.
- Cà Phê Đá Xay (Coffee Slush): A modern twist on traditional Vietnamese coffee, offering a refreshing and energizing experience.
Potential Drawbacks and Considerations
Sodium Intake
While Vietnamese cuisine offers many health benefits, it's important to be mindful of sodium intake. A national nutrition strategy in Vietnam aims to reduce salt intake, which is currently nearly double the daily intake recommended by the World Health Organization. Vietnamese people get a significant portion of their salt from condiments added to food, such as bot canh (a powdered, mixed-seasoning soup broth) and nước mắm (fish sauce). Mắm (fermented seafood preserved in salt) is another high-sodium ingredient used in various dishes. Even tropical fruits are often eaten with salt and chili pepper or lime.

Ajinomoto Vietnam (AVN) is supporting the Vietnamese government's sodium reduction targets through initiatives like the School Meal Project and Mother and Children Project. These programs aim to raise awareness about salt intake and educate people about delicious salt reduction using umami seasoning, which contains only one-third the amount of sodium compared to table salt.
Cost of a Healthy Diet
The Cost of a Healthy Diet (CoHD) indicator estimates the lowest cost of healthy diets. In Vietnam, the average CoHD between 2016 and 2020 was 3.08 international dollars. Nutrient-rich food groups, including protein-rich foods, vegetables, fruits, and dairy, comprised approximately 80% of the total CoHD. Dairy accounted for the largest proportion of the CoHD. This highlights the importance of addressing affordability to ensure access to healthy diets for all.
Examples of Healthy Vietnamese Dishes
Here are some examples of delicious and healthy Vietnamese dishes:
- Cháo Gà (Chicken Congee): A rice porridge that is easy to digest and can be enhanced with additional ingredients like mushrooms, beans, peas, or traditional herbs.
- Gỏi Ngó Sen (Lotus Root Salad): A raw lotus root salad, rich in fiber and vitamins, that aids digestion, lowers blood pressure, and reduces cholesterol.
- Cá Kho Tộ (Clay Pot Fish): Braised fish cooked in a clay pot, which helps to cook evenly and caramelize without the need for sugar.
- Canh Chua (Sour Soup): A sour soup with pineapple, tomato, and bean sprouts in a tamarind-flavored broth, often with fish or prawns.
- Rau Muống (Stir-Fried Water Spinach): Stir-fried water spinach with garlic, rich in vitamins, minerals, and antioxidants.
