Now, let us look at the nutrition that sardines provide.
Nutritional Information
According to the USDA, 2 sardines give you 209 calories along with a host of nutrients, ranging from vitamin A and vitamin D to a source of calcium and phosphorus. What’s better, sardines have no carbohydrates or sugar, making them very healthy. Find below the nutritional value of sardines as given by USDA (1). Sardines’ nutritional value is very high and can be beneficial to your health in many ways. Let’s read next about the different health benefits of sardines.
Potential Health Benefits Of Sardines
Sardines are considered a great addition to our diets because they offer a multitude of benefits. Due to their large reserve of nutrients such as vitamins and essential minerals, they are considered healthy (2). It is also a high-protein food that is likely to keep you satiated for a long time. Let’s check out all the benefits in detail below.
May Help Reduce The Symptoms of Alzheimer’s
Did your mother ever tell you that eating fish is good for your brain? She was probably right. Sardines fall under the category of fatty fish due to its high level of omega-3 fatty acids. A study was conducted to see the effect of fatty fish such as sardines in diseases like dementia, Alzheimer’s disease, and vascular disease. According to the 2022 Alzheimer’s Disease Facts and Figures published in Alzheimer’s & Dementia: the Journal of the Alzheimer’s Association, approximately 6.5 million Americans aged 65 and older live with Alzheimer’s dementia. In 2019, 121,499 deaths from Alzheimer’s were recorded in the United States, making it the sixth-leading cause of death. There was an increase of over 145% in reported deaths from Alzheimer’s between 2000 and 2019, contrasting declines in deaths from stroke, heart disease, and HIV during the same period. The researchers found that in comparison to lean fish, consumption of fatty fish twice a week showed a decrease in the risk of developing dementia by 28% and Alzheimer’s by 41%. While this study suggests that fatty fish may be good for brain health, more studies need to be conducted to understand the connection between sardines and brain health (3).
May Play A Role In Preventing Cardiovascular Diseases
Eating a healthy diet rich in fish may prevent the development of cardiovascular disease (4). Experts conducted a study to see the effect of eating a sardine-rich diet on inflammation, metabolic control, and gut bacteria. 35 patients diagnosed with diabetes were asked to follow a standard diabetes diet, or a diet rich with 100g of sardines for 5 days for 6 months. The results saw a decrease in plasma insulin levels and an increase in gut bacteria. Researchers suggest that having a sardine-enriched diet may be essential in reducing the risk of heart diseases, although more research needs to be conducted on this topic (5).
May Play A Protective Role Against Diabetes
In a study that was conducted, 152 people with prediabetes and old age were asked to consume sardine two times per week for 1 year. The results showed that those in the sardine group had a decreased risk of developing diabetes. Along with this, the patients showed a decrease in triglyceride as well as an increase in HDL cholesterol (good cholesterol), omega3, and bile acid levels. This study indicates that sardines may play a protective role against diabetes and anyone at a high risk of developing diabetes (7).
May Aid In The Development Of Healthy Bones
The calcium in sardines is reported to be 91.7 mg, according to USDA (1). Calcium and vitamin D are necessary for the development of healthy bones and play an important role in preventing bone disorders such as osteoporosis, and rickets (7), (8). Sardines are high in calcium, so you can add these silver swimmers to your diet for healthy bones (9). A Vitamin D-rich food like sardine can also lowers cholesterol levels and reduces the chances of muscle inflammation.
May Protect Your Skin From UV-rays Of The Sun
If you like getting tanned but still need to protect your skin from those UV rays, then sardines may help you in that. An in-vitro study was conducted to see the anti-inflammatory activity and skin absorption of essential fatty acids from fish oil extracts. The researchers obtained oils from three fish oils, namely, sardine, mackerel, and horse mackerel. The results showed that sardine fish oil extract had a higher concentration of omega-3 fatty acids and anti-inflammatory activity compared to the other two (10). While the study suggests that sardines may play a role in protecting our skin UV rays, more studies need to be conducted to substantiate this fact. Conner Phillips, a YouTuber, shared how eating sardines continuously for over 60 days improved his health. He found that he felt more satiated and the nutrients in the fish helped him last an entire day. He said, “Sardines are amazing for if you’re gonna go out to eat. Eating one of these (sardines) first off I found, first, I make better decisions; second, I’ve found that I feel better when we’re done eating (i).“ You can see from the above section that sardine benefits you in more than one way. From playing a role in the development of healthy bones to protecting your skin against UV-rays, and diabetes, sardines may prove to be a great addition to your diet. Let’s look at the different ways through which you can add sardines to your menu.

Let’s see about the possible side effects you can develop from eating sardines.
Possible Side Effects Of Sardines
Sardines, like their marine siblings, are very good for us. But just like everything, it has its cons too. With pollution increasing every year and rivers being poisoned with toxic metals, it has become a little dangerous to consume fish. A study was conducted to see the negative effects of sardines on rats (11). The rats were fed either red or white sardines for 60 days. The researchers observed an increase in their uric acid level along with the high accumulation of lead in the liver. Thus, it is highly advised that you buy fresh sardines and wash them properly before consumption. Excessive sardine consumption may have several other side effects:
Risk Of Mercury Poisoning: Mercury is a heavy metal that may cause severe health issues. This often happens when the body absorbs too much mercury from food sources like fish.
Risk Of Heart Disease: Sardines are usually canned in vegetable oils. These oils are rich in omega-6 fatty acids. Consuming excessive amounts of omega-6 fatty acids (through different food sources) may increase the risk of heart diseases, obesity, diabetes, and other health conditions.
May Cause Vitamin A Excess: Vitamin A is a fat-soluble vitamin that boosts your eyesight, immune system, and reproductive organs function. However, consuming excess vitamin A may increase the risk of developing cancer.
Currently, there is little research to show the possible side effects of sardines on our health. More studies will need to be conducted to understand the link between the two. Let us have a look at some simple and delicious ways to prepare sardines.
