Kewpie Japanese Mayonnaise contains 686 kcal, 74.6g of fat (10.9g saturated), 0.6g of carbohydrate (0.4g sugar), 2.5g of protein and 1.8g of salt per 100g. A standard mayonnaise portion — 1 teaspoon (7g) — delivers 48 kcal, 0.03g of sugar and 0.13g of salt.
Kewpie is the most popular mayonnaise in Japan, distinguished by its use of egg yolk rather than whole egg (giving a richer, creamier emulsion), rice vinegar for a milder tang, and MSG (E621) for umami depth. At 686 kcal per 100g and 74.6g of fat, it is similar in energy density to Hellmann's Real Mayo. The MSG content contributes to its distinctively savoury flavour.
Portion size matters significantly for condiments. A small squeeze or single teaspoon contributes little to daily intake. But condiments are easy to apply generously: 1 teaspoon (7g) delivers 0.03g of sugar and 0.13g of salt, while 4 tablespoons (60g) delivers 0.24g of sugar and 1.08g of salt. Adding multiple condiments to a single meal multiplies this further.
Sugar
Kewpie Japanese Mayonnaise contains 0.4g of sugar per 100g. 1 teaspoon (7g) delivers 0.03g of sugar. Sugar in condiments is all free sugar: unlike the naturally occurring sugars in whole fruit or plain dairy, there is no food matrix to slow absorption.
Salt
Kewpie Japanese Mayonnaise contains 1.8g of salt per 100g. 1 teaspoon (7g): 0.13g (2% of the adult daily limit of 6g); 1 tablespoon (15g): 0.27g (5% of the adult daily limit of 6g); 2 tablespoons (30g): 0.54g (9% of the adult daily limit of 6g); 4 tablespoons (60g): 1.08g (18% of the adult daily limit of 6g).
Ingredients and ultra-processed food
Kewpie Japanese Mayonnaise is a commercially produced mayonnaise. Its ingredients are: Vegetable oils 70% (rapeseed oil, soybean), egg yolk 14%, grain vinegar (water, alcohol, apple juice, corn, barley malt, glucose, sake lees, sugar), water, salt, spice (mustard), flavour enhancer (E621/MSG), spice extract (mustard). Uses egg yolk only rather than whole egg, and contains MSG..
A home-made equivalent would typically require fewer ingredients. The processing aids are used to deliver a consistent flavour, texture and shelf life at scale that home preparation cannot match.
