Mayonnaise glycemic index (GI)
Mayonnaise is very low in sugars, containing less than 1g in a 100g serving. Because of this, it is exceedingly difficult to consume a portion of mayonnaise needed to calculate an exact number for its glycemic index. However, it is assumed to be very low.
The main ingredients of mayonnaise are egg yolk, vegetable oil, vinegar or lemon juice, and flavorings or spices. If we look at these components separately, all have glycemic indices close to zero.
However, despite the low glycemic index, mayonnaise should be consumed in moderation since mayonnaise is a high-caloric food, and consuming high calories and being in a caloric surplus can lead to weight gain which in turn increases risks of cardiovascular and metabolic diseases (1).
