Eating fish whole: Sardines
Different parts of a fish have different types of nutrients that are important for our health; this includes bones and organs. Therefore it makes sense to consume the fish whole, not just filets made from it. This is easier to do with small than big fish.Small fish have the added advantage that they have very low concentrations of metals, compared to large fish. The reason for this is that small fish are usually low in the food chain, typically feeding mostly on plankton, especially algae. Large carnivorous fish tend to accumulate metals in their body, and their consumption over time may lead to the accumulation of toxic levels of metals in our bodies.
One of my favorite types of small fish is the sardine. The photo below is of a dish of sardines and vegetables that I prepared recently. Another small fish favorite is the smelt (see this post). I buy wild-caught sardines regularly at the supermarket.
Sardines are very affordable, and typically available throughout the year. In fact, sardines usually sell for the lowest price among all fish in my supermarket; lower even than tilapia and catfish. I generally avoid tilapia and catfish because they are often farmed (tilapia, almost always), and have a poor omega-6 to omega-3 ratio. Sardines are rich in omega-3, which they obtain from algae. They have approximately 14 times more omega-3 than omega-6 fatty acids. This is an excellent ratio, enough to make up for the poorer ratio of some other foods consumed on a day.

Below is a simple recipe. I used it to prepare the sardines shown on the photo above.
- Steam cook the sardines for 1 hour.
- Spread the steam cooked sardines on a sheet pan covered with aluminum foil; use light olive oil to prevent the sardines from sticking to the foil.
- Preheat the oven to 350 degrees Fahrenheit.
- Season the steam cooked sardines to taste; I suggest using a small amount of salt, and some chili powder, garlic powder, cayenne pepper, and herbs.
- Bake the sardines for 30 minutes, turn the oven off, and leave them there for 1 hour.
The veggies on the plate are a mix of the following: sweet potato, carrot, celery, zucchini, asparagus, cabbage, and onion. I usually add spinach but I had none around today. They were cooked in a covered frying pan, with olive oil and a little bit of water, in low heat. The cabbage and onion pieces were added to the mix last, so that in the end they had the same consistency as the other veggies.
I do not clean, or gut, my sardines. Normally I just wash them in water, as they come from the supermarket, and immediately start cooking them. Also, I eat them whole, including the head and tail. Since they feed primarily on plant matter, and have a very small digestive tract, there is not much to be “cleaned” off of them anyway. In this sense, they are like smelts and other small fish.
For many years now I have been eating them like that; and so have my family and some friends. Other than some initial ew’s, nobody has ever had even a hint of a digestive problem as a result of eating the sardines like I do. This is very likely the way most of our hominid ancestors ate small fish.
If you prepare the sardines as above, they will be ready to store, or eat somewhat cold. There are several variations of this recipe. For example, you can bake the sardines for 40 minutes, and then serve them hot.
You can also add the stored sardines later to a soup, lightly steam them in a frying pan (with a small amount of water), or sauté them for a meal. For the latter I would recommend using coconut oil and low heat. Butter can also be used, which will give the sardines a slightly different taste.
