How much tuna is too much tuna I eat tuna at least once a day just plain old tuna with half avocado
With the avocado, that may be a little high in fat
tuna has one of the highest counts of mercury. It's too bad too cause it is such a good source of protein and omega 3s. So yeah everyday might be a little excessive
No the avacado is better. Avacado is a super food. Eat it and enjoy. Mayo is bad. I have no mayo in my home. I haven't used may since the early 2000. I wasn't raised on it. So I have no need for it.
tuna won't kill ya! 2 or 3 tins a week is fine, just switch it up with salmon/tilapia/shrimp
with mayo you may as well inject fat straight into your veins! I used to love tuna and mayo but have it with soy sauce now instead or make a tuna melt with low fat cheese.
Avocado is awesome too, just be careful as it's high in healthy fats so usually 1/2 a day or one is best for most people. As you've told me that you have a problem with carbs though it might be better for you to have higher healthy fats each day to compensate
