4 min read

According to a 2023 study on online food delivery in Thailand, many popular menu items were found to be high in sodium, with average consumption levels exceeding global health recommendations. This statistic brings a vital question to light for health-conscious diners: is there high sodium in Thai food, and how can you navigate it?

Quick Summary

Many Thai restaurant dishes contain significant sodium from sauces like fish sauce, soy sauce, and shrimp paste. Sodium content varies by dish and preparation, with stir-fries and soups often being highest. Consumers can lower sodium by making mindful choices and requesting adjustments.

Key Points

Sodium is common: Many Thai dishes contain high sodium due to frequent use of fish sauce, soy sauce, and shrimp paste.
Restaurant food is often higher: Westernized versions of Thai food and some street foods may be higher in sodium than traditional home-cooked meals.
Choose wisely: Dishes like fried rice, Pad Thai, and many soups tend to be highest in sodium, while fresh spring rolls or grilled options are often lower.
Ask for modifications: Requesting less sauce or having it served on the side is a simple and effective way to reduce sodium at restaurants.
Cook at home: Cooking Thai food yourself offers total control over ingredients and allows for using low-sodium alternatives.
Balance is key: The focus should be on moderation and being mindful of high-sodium ingredients rather than avoiding Thai food entirely.

Understanding the Saltiness of Thai Cuisine

Thai cuisine is celebrated for its complex and balanced flavor profile, which expertly combines salty, sweet, sour, spicy, and bitter notes. While this balance creates delicious dishes, the salty component is often achieved through high-sodium ingredients that can pose a challenge for those watching their salt intake. In Western restaurants, this is sometimes compounded by larger portions and adapted recipes that are less traditional and higher in salt, sugar, and fat.

The Key Sources of Sodium

Several staple Thai ingredients contribute significantly to the overall sodium content of a meal. Understanding these can help you make more informed choices.

Fish Sauce (Nam Pla): This fermented fish condiment is the undisputed champion of sodium in Thai cooking, used for its deep, savory umami flavor. A single tablespoon of fish sauce can contain up to 96% of the average recommended daily salt intake.
Soy Sauce and Oyster Sauce: These are also common additions, especially in stir-fries and marinades. One tablespoon of average soy sauce contains 61% of the daily recommended salt, while oyster sauce is also high, with about 36% per tablespoon.
Shrimp Paste: A key ingredient in many curry pastes and certain dishes, shrimp paste is another high-sodium component that adds a distinct flavor but also a substantial salt kick.
Curry Pastes: Pre-packaged curry pastes contain a blend of these salty elements, alongside spices and herbs. While convenient, they are a hidden source of sodium that can quickly elevate the saltiness of a dish.
MSG: While less common in traditional cooking, some restaurant and street vendors add monosodium glutamate to enhance flavor, which also contributes to the sodium load.

High-Sodium Thai Dishes to Watch For

Certain Thai dishes are notorious for their high sodium levels due to their reliance on salty sauces and stir-frying techniques. These include:

Fried Rice: Often made with a generous amount of soy and fish sauce, Thai fried rice can be a sodium-dense meal. For example, one serving of Thai fried rice can contain over 1300mg of sodium, or more than half the daily value.
Pad Thai: This popular noodle dish, while flavorful, relies heavily on fish sauce and sometimes dried shrimp, making its sodium content a concern. A single serving can provide over 600mg of sodium.
Soups (Tom Yum, Tom Kha): Despite often being low in calories, Thai soups can be very high in sodium. The broth is typically seasoned generously with fish sauce.
Noodle Dishes: Besides Pad Thai, other noodle dishes like Pad See Ew are often made with soy sauce, contributing to high sodium levels.

Making Smarter, Lower-Sodium Choices

It is entirely possible to enjoy the deliciousness of Thai cuisine while controlling your sodium intake. Making modifications when ordering or cooking can dramatically lower the salt content without sacrificing flavor.

Here are some tips for ordering at a restaurant:

Request less fish sauce and soy sauce. Many kitchens are happy to accommodate this request.
Ask for sauces or dressings on the side. This gives you control over how much you add.
Choose grilled or steamed options instead of fried. Chicken or fish satay (with less peanut sauce) and steamed fish are excellent choices.
Opt for fresh spring rolls (without the heavy dipping sauce) over fried egg rolls.
Pair saucy dishes with more steamed rice and vegetables to dilute the saltiness. Ask for more vegetables or bean sprouts to be added to noodle dishes.

For home cooking, you have complete control:

Use low-sodium soy sauce or tamari, or experiment with soy-free, low-sodium sauce substitutes.
Substitute some of the fish sauce with other ingredients that provide umami, such as a smaller amount of fish sauce blended with lime juice, garlic, and fresh herbs.
Make your own curry pastes and sauces from scratch to control the salt content. Many Thai herbs and spices like lemongrass, galangal, and chili add intense flavor without sodium.

High vs. Low Sodium Thai Dishes


Dish	Typical Sodium Content (restaurant)	Lower-Sodium Alternative	Notes
Fried Rice	1300+ mg (58%+ DV)	Steamed rice with lean protein and veggies	Request less soy/fish sauce; add your own spices at home.
Pad Thai	650+ mg (31%+ DV)	Fresh spring rolls or Chicken Satay	Ask for less sauce; control portion of sauce on the side.
Tom Yum Soup	800+ mg (variable)	Chicken or vegetable soup broth	Request a version with less fish sauce; focus on the herbs.
Green Curry	Varies widely	Grilled protein with a side of steamed vegetables	Curries use a lot of fish sauce and salty curry paste.
Pad See Ew	Varies widely	Stir-fried veggies with garlic and ginger	Ask for less soy and oyster sauce.

Conclusion

So, is there high sodium in Thai food? The answer is a qualified 'yes', particularly in restaurant and street food preparations that rely on heavy sauces and flavor enhancers. The traditional Thai preference for a complex flavor balance, which includes saltiness from key ingredients like fish sauce, means that many dishes contain a significant amount of sodium. However, with conscious ordering and preparation, you can enjoy this vibrant and flavorful cuisine while keeping your sodium intake in check. By choosing wisely and asking for modifications, you can savor the health benefits of fresh vegetables, lean proteins, and beneficial herbs that Thai food has to offer, without the excessive salt.
