Protein in Tuna: A Rich Source of Essential Nutrients
Tuna is a fish renowned for its high protein content. A 3-ounce serving of canned tuna contains approximately 20 grams of protein. This protein is of high quality, meaning it is easily absorbed and utilized by the body. Tuna is also a good source of essential amino acids, which are the building blocks of protein. These amino acids are vital for muscle growth, repair, and overall bodily function.

The protein content of bread varies depending on the type of bread used. Whole-wheat bread tends to have a higher protein content than white bread. For example, a slice of whole-wheat bread contains about 3 grams of protein, while a slice of white bread contains about 2 grams of protein. However, the protein content of bread is generally lower than that of tuna.
Other Ingredients: Minimal Protein Contribution
Other ingredients in a tuna sandwich, such as mayonnaise, lettuce, and tomato, contribute minimal amounts of protein. Mayonnaise contains a small amount of protein from eggs, while lettuce and tomato are primarily sources of vitamins and minerals.
