How much tuna can a diabetic eat?

My father has diabetes and he loves seafood, especially tuna. We're always careful about his diet. I was wondering, how much tuna can a diabetic eat without it causing any issues?

For diabetes, it is all about moderation, my mother always says. Tuna is good for protein, but it can have mercury sometimes, so not too much. My doctor told me to have fish a few times a week, maybe a small serving. Best to ask your own doctor or a dietician for a personalized plan.

This is exactly the kind of question that makes me anxious! Tuna is healthy, but then you worry about mercury or if it spikes sugar. I always wonder how much is 'moderate.' Does anyone else constantly second-guess their food choices with diabetes?

Tuna is generally good for diabetics – high protein, low carb. However, moderation is key due to potential mercury levels, especially in larger tuna species. Aim for 2-3 servings (around 100-150g per serving) of light tuna per week. Always prefer tuna in water, not oil, and check the sodium content.

My uncle has diabetes and he eats tuna sometimes. His dietician told him it's good for protein but don't overdo it because of mercury. Like maybe twice a week, small portion. And always the one in water, not oil. Check the sodium too, some are super high.

Tuna can be a good protein source for diabetics. It's usually fine in moderation. Just be mindful of the type (in water is better) and portion size. It's always best to discuss with your doctor or a dietician for personalized advice.
