How many calories in a serve of Kewpie mayo?

Kewpie mayonnaise is a popular Japanese mayonnaise brand made with egg yolks, vinegar, and rapeseed oil. It has a distinct rich, eggy flavor and creamy texture that makes it a versatile condiment or ingredient. Understanding the calorie content of Kewpie mayonnaise can help with meal planning and making informed food choices. This article will provide a comprehensive overview of the calories and nutrition facts in Kewpie mayonnaise.

Serving Size

The standard serving size for mayonnaise, including Kewpie mayonnaise, is generally considered to be 1 tablespoon or 15 grams. This is the reference amount used on the Kewpie mayonnaise nutrition label and for tracking calories. So when looking at the calories in Kewpie mayonnaise, values are typically based on a 1 tablespoon (15g) serving.

Calories per Serving

According to the nutrition information on the Kewpie Mayonnaise label:

There are 90 calories in 1 tablespoon (15g) of Kewpie mayonnaise.

This calorie count is based on the regular, full-fat Kewpie mayonnaise. Kewpie also makes a reduced-fat mayonnaise with half the calories.

So in summary:

  • 1 tablespoon (15g) Kewpie mayonnaise contains 90 calories

This standard serving size and calorie information provides a useful reference point for tracking your mayonnaise intake. But it’s also important to note that the amount of mayonnaise used in a serving can vary based on the dish, personal preferences, and other factors. The actual calories you consume will depend on the total amount of mayonnaise eaten.

Calories in Different Serving Sizes

While 1 tablespoon (15g) is considered a standard serving size, you may use more or less mayonnaise than that in a particular recipe or dish. Here is a breakdown of the calories in different serving sizes of Kewpie mayonnaise:

1 teaspoon (5g)

  • 1 teaspoon of Kewpie mayonnaise contains 30 calories

1/2 tablespoon (7.5g)

  • 1/2 tablespoon of Kewpie mayonnaise contains 45 calories

1 tablespoon (15g)

  • 1 tablespoon of Kewpie mayonnaise contains 90 calories

2 tablespoons (30g)

  • 2 tablespoons of Kewpie mayonnaise contains 180 calories

1/4 cup (60g)

  • 1/4 cup of Kewpie mayonnaise contains 360 calories

As you can see, the calorie count scales up linearly based on the amount of mayonnaise used. Knowing the calories per tablespoon or gram makes it easy to estimate the calories in any given serving size.

This table summarizes the calories in different serving sizes:

Amount Calories
1 teaspoon (5g) 30
1/2 tablespoon (7.5g) 45
1 tablespoon (15g) 90
2 tablespoons (30g) 180
1/4 cup (60g) 360

So if you use 2 teaspoons of mayo on a sandwich or 1/4 cup of mayo in a potato salad, you can easily estimate the calories by looking at this table.

Calories in Reduced-Fat Kewpie Mayo

In addition to the regular, full-fat mayonnaise, Kewpie also makes a reduced-fat mayonnaise with half the calories. Here are the nutrition facts for the reduced-fat Kewpie mayonnaise:

1 tablespoon (15g) reduced-fat Kewpie mayonnaise

  • 45 calories
  • 4.5g fat

As you can see, the reduced-fat Kewpie mayonnaise contains only 45 calories per tablespoon compared to 90 calories in the regular mayonnaise. So substituting the reduced-fat version can significantly reduce the calorie content of your dishes made with mayonnaise.

If using reduced-fat Kewpie mayonnaise, remember that the calorie count for other serving sizes will also be half that of the regular mayonnaise. For example:

  • 1 teaspoon reduced-fat Kewpie mayo: 15 calories
  • 2 tablespoons reduced-fat Kewpie mayo: 90 calories

So the reduced-fat variety is a lower-calorie option while still providing that signature Kewpie flavor.

Calories Compared to Other Mayonnaise Brands

How does Kewpie mayonnaise compare to other popular mayonnaise brands in terms of calories?

Here is a nutrition comparison of 1 tablespoon serving sizes of various mayonnaise brands:

Mayonnaise Brand Calories
Kewpie Mayonnaise 90
Hellmann’s Real Mayonnaise 90
Best Foods Mayonnaise 90
Duke’s Mayonnaise 100
Kraft Mayonnaise 90

As you can see, the calorie content is very comparable across popular mayonnaise brands, with most containing 90 calories per serving. Kewpie mayonnaise fits right in line with other standard mayonnaise varieties. Duke’s mayonnaise is slightly higher at 100 calories per tablespoon. But overall, there is not a huge calorie difference between mainstream mayonnaise brands.

So Kewpie mayonnaise contains about the same calories as other leading full-fat mayonnaise options. The reduced-fat Kewpie mayonnaise provides a lower-calorie alternative at just 45 calories per serving.

Effects of Ingredients on Calories

The main ingredients that contribute to the calorie content in Kewpie mayonnaise are the oil and egg yolks.


Mayonnaise gets a majority of its calories from oil. Kewpie mayonnaise is made with rapeseed oil, also known as canola oil. A tablespoon of oil contains 120 calories, making it a very calorie-dense ingredient. Using less oil could lower the calorie count, while more oil increases calories.

Egg yolks

Egg yolks are also high in fat and calories, providing about 55 calories in each yolk along with nutrients like vitamin A, folate, and cholesterol. Using more egg yolks adds more calories to the mayonnaise. Egg yolks also contribute to the rich texture.


Kewpie mayonnaise uses both distilled vinegar and rice vinegar. Vinegar adds flavor but minimal calories, with only about 3 calories per tablespoon.


Some mayonnaise contains added sugars like sucrose or high fructose corn syrup, which adds additional calories. Kewpie mayonnaise does not contain added sugars.


While salt enhances flavor, it contributes no calories.


Water also adds bulk and texture without adding any calories.

So in summary, the high amounts of oil and egg yolks are what mainly contribute to the calorie content in Kewpie mayonnaise. Reducing or changing these ingredients could alter the calorie profile, but would also affect the taste and texture.

Effects of Storage and Preparation on Calories

How you store and prepare Kewpie mayonnaise does not significantly affect the calorie content. However, here are some things to consider:


– Properly storing mayonnaise in the refrigerator according to the package instructions ensures no separation of ingredients or degradation that could alter the nutrition profile.

– Leaving mayonnaise out at room temperature for too long can cause separation of oil, leading to inconsistent calories when served.


– The calories remain the same whether Kewpie mayonnaise is served chilled, at room temperature, or briefly warmed in a recipe.

– Whipping or beating the mayonnaise does not change the calories but adds volume and changes texture.

– Combining mayonnaise with other ingredients like spices, lemon juice, or herbs does not alter the calories significantly.

– Spreading mayonnaise thinner or thicker on a dish changes the total amount used and thus calories consumed.

So while storage and preparation does not directly affect calorie content, these factors can impact serving size and how much mayonnaise (and calories) you ultimately consume.

Tips for Cutting Calories

If you are looking to reduce the calorie intake from mayonnaise, here are some tips:

– Use a reduced-fat mayonnaise like Kewpie’s low-calorie option
– Opt for lighter serving sizes like 1 teaspoon or 1/2 tablespoon
– Substitute half the mayonnaise in a recipe with low-calorie Greek yogurt
– Mix mayonnaise with mustard, vinegar, or lemon juice to make it spread further
– Choose lower-calorie toppings and fillings in sandwiches and wraps
– Use mayonnaise sparingly as a spread or dressing rather than a main ingredient
– Or simply avoid it altogether if looking to significantly cut calories

Making small tweaks to how you use Kewpie mayonnaise can help reduce excess calories while still allowing you to enjoy its signature flavor.

Nutritional Benefits

In addition to calories, Kewpie mayonnaise does offer some nutritional value:

Healthy fats
– The rapeseed oil provides heart-healthy monounsaturated and polyunsaturated fats.

– Egg yolks contain choline, an essential nutrient important for brain and liver health.

Vitamin E
– Rapeseed oil provides vitamin E, a powerful antioxidant.

So while high in calories and fat, the ingredients in Kewpie mayonnaise like oil and egg yolks also impart some nutritional benefits.


To summarize key points:

– 1 tablespoon (15g) of Kewpie mayonnaise contains 90 calories

– The reduced-fat version has 45 calories per serving

– Calorie content is comparable to other popular mayonnaise brands

– Oil and egg yolks primarily contribute to calories

– Storage and preparation have minimal effects on calories
