Introduction

Thousand Island and French dressing are two of the most popular American condiments. In this article, we will look at how much nutrition each dressing adds to a dish and how the two compare to each other overall.

Contents

Despite the name, French dressing is an American salad dressing, just like Thousand Island. Both condiments are also usually made with ketchup as the base. 

However, the most important ingredient in Thousand Island is mayonnaise, usually mixed with ketchup as the base. Depending on the recipe, Thousand Island can also contain finely chopped bell peppers, pickles, pimentos, olives, onions, horseradish, etc.

French dressing is based on a mix of vinegar, oil, and sugar. Due to these ingredients, the dressing was often referred to as vinaigrette. Vinaigrette is a dressing originating in France, which is made by mixing oil with vinegar. This is where French dressing gets its name.

French dressing can also contain paprika, mustard, onions, and various seasonings.

Taste and Use

As can be seen from their ingredients, Thousand Island, being a mayo-based dressing, is heavier and thicker, usually used in sandwiches. French dressing, on the other hand, is based on oil and vinegar and is, therefore, thinner and lighter, often used to add flavor to salads or other dishes.

While there are differences in flavors and textures, Thousand Island is more similar to Russian dressing, as both are based on a mixture of ketchup and mayonnaise. If interested, you can read more about how Thousand Island compares to Russian dressing.

French dressing more closely resembles Catalina dressing - a red-colored condiment that is also based on a mixture of oil, vinegar, and sugar.

Fats

Thousand Island contains three times more fats compared to reduced-fat French dressing. However, regular French dressing is slightly higher in fats than Thousand Island.

The fat content of both condiments consists mainly of “healthy” unsaturated fats and fewer “unhealthy” saturated fats. Reduced-fat French dressing has a more favorable fat profile, containing very few saturated fats.

Thousand Island provides 26mg of cholesterol per 100g serving, while French dressing does not contain cholesterol. This can be explained by the mayonnaise found in Thousand Island.

Health Impact

Cardiovascular Health

Research has found a direct correlation between higher sodium intake and increased cardiovascular disease risk. The lowest risk of cardiovascular events and death occurs in people consuming an average sodium intake of 3 to 5g per day (2).

Thousand Island and French dressing are both very high in sodium, falling in the top 10% of foods as a source of sodium. However, Thousand Island is higher in sodium compared to French dressing.

Increased olive oil consumption, along with decreased mayonnaise consumption, has been studied to decrease the risk of cardiovascular disease and overall mortality (3). This indicates that French dressing made with olive oil might be healthier than Thousand Island.

Oral Health

Enamel erosion is the loss of the tooth enamel, which normally covers the tooth, protecting it from harm. Erosion is usually caused by acidic foods, such as vinegar and lemon juice. 

French dressing has been researched to cause more dental wear compared to Thousand Island (4). 

Bone Health

Vitamin K plays an important role in a vital role in regulating blood clotting and bone health (5). As mentioned above, Thousand Island is four times higher in vitamin K than French dressing.
