Protein is made up of 22 amino acids. 9 (i think) are essential, while the remaining 13 can be made up from those 9. As bodybuilders we want to supply our bodies with all 22 so they can be put to use straight away. Tuna is either missing, or very low in some amino acids, so it's best to eat another protein source with it to get a better (more complete) spread of aminos. Same goes for any none animal sources of protein such as legumes.
You could also add amino acids to each deficient meal. I sometimes use Extreme Aminos. |
