How many carbs are in tuna fish with mayonnaise?

I can't give you an exact number of carbs for tuna fish with mayonnaise. Here's why:

* Tuna variations: There are many types of tuna (canned, fresh, different brands). Their carb content can vary slightly.

* Mayonnaise types: Mayonnaise comes in regular, light, and even low-carb versions. The amount of carbs will vary significantly between these types.

* Serving size: The amount of tuna and mayonnaise you use will drastically change the total carb count.

Here's what you can do:

1. Check the labels: Look at the nutrition information on your specific tuna and mayonnaise containers. This will provide the most accurate carb counts for those products.

2. Calculate based on serving size: Once you know the carbs per serving of each ingredient, multiply by the amount you're using to get your total.

General guidelines:

* Tuna: Canned tuna in water is usually very low in carbs, often containing less than 1 gram per serving.

* Mayonnaise: Regular mayonnaise can have about 1 gram of carbs per tablespoon. Light versions often have less, and low-carb mayo can be even lower.

Remember, this is a very rough estimate. Always refer to the product labels for the most accurate information.
