I am curious about whether tuna or sardines are healthier. This is a general question, not about a particular diet. I know the idea of what’s healthy is subjective but I suppose the factors that one could compare include daily values of minerals and vitamins that each provide, salt level, and mercury, trans-fats, and other concerns. Thanks.
Sardines for me. Too paranoid about mercury content in tuna, plus they taste better (to me).
I like toasting some bread with a little olive oil or mayo, seasoned tomato slices (salt is fine), arugula, squirt of lemon juice, sardines).
It’s better pressed.
If I’m bored I eat it out of the can (but it’s gotta be in oil not water 😬).
Both tuna and sardines are healthy options as they are high in protein and omega-3 fatty acids. Sardines are generally considered to be a better choice as they are lower in mercury and other toxins commonly found in larger fish such as tuna. Sardines also have a higher bone-to-meat ratio, which means they are a good source of calcium. They also have a higher amount of vitamin D. Tuna also has a good amount of omega-3s, but it’s also a higher source of mercury, which can be harmful in large amounts. The best choice depends on the individual’s dietary restrictions, preferences, and the source of the tuna or sardines. It’s always important to get fish from a reputable source and to be aware of any advisories or warnings regarding the consumption of certain fish species.
Sardines are generally healthier in mineral content and less mercury. Apparently they are also more sustainably fished in general. Overall better for you and the environment.
Not a scientific source but a decent overview of the different profile of tuna vs sardines and links to sources: https://foodstruct.com/compare/fish-sardine-atlantic-cannedinoil-drainedsolidswithbone-vs-tuna
Also I I use an app called GoodFish that tells you what are the most sustainable brands/types of fish in your area. I’m I australia though so not sure if there is an equivalent app for other parts of the world.
