Yes, sardines are a good source of magnesium, providing a valuable amount of this essential mineral along with other nutrients like omega-3s, calcium, vitamin D, and protein, making them a nutrient-dense food for bone health and overall well-being. While canning can reduce some mineral content, they remain a significant source.
Moreover, sardines are a source of potassium, magnesium, and zinc, which are nutrients with observed BP lowering properties, as well as niacin and zinc, which in turn are candidates for improving circulating levels of lipids and lipoproteins (40–44).
Food. Good sources of magnesium include green leafy vegetables, legumes, nuts, seeds, whole grains, and certain beverages. Magnesium may also be added to some breakfast cereals and other fortified foods. In general, approximately 30% to 40% of the magnesium obtained from food and beverages is absorbed by the body.
You feel good after eating sardines because their rich nutrients, especially omega-3s, Vitamin D, B12, protein, calcium, and iron, boost mood, energy, brain function, heart health, and bone strength, while providing sustained fullness, making you feel satisfied and uplifted. This nutrient density combats deficiencies that can cause low mood or fatigue, leading to a positive feeling of well-being.
Ten common signs of low magnesium include fatigue, muscle cramps/twitches, loss of appetite, nausea, weakness, abnormal heart rhythms, numbness/tingling, headaches, anxiety/irritability, and insomnia, with more severe deficiency potentially causing seizures or high blood pressure. These symptoms often start subtly and worsen, affecting both physical and mental health.
Sardines may contain excess sodium and are high in purines.
Sardines and salmon are considered to be high in proteins, although sardines contain slightly higher levels. Sardines contain 24.6 grams of protein per 100 grams, while salmon contains 22.1 grams. The essential amino acid profile of sardines is richer than that of salmon.
Fish Help You Have a Healthy Heart
Fish contain omega-3 fatty acids that act as an energy source and help keep the lungs, blood vessels, and immune system functioning properly. Omega-3 fatty acids are found in every kind of fish but are especially high in salmon, trout, sardines, herring, mackerel, tuna, and oysters.
It's recommended that you eat two servings of fruit per day as part of a healthy diet. Consider these to check that box plus the one for magnesium: Avocados: One whole avocado = 58 mg of magnesium. Bananas: One medium banana = 32 mg of magnesium.
Common causes of low magnesium include:
For drinks high in magnesium, opt for mineral waters, fruit juices (especially orange, cherry, watermelon), plant-based milks (soy, almond), and homemade concoctions using raw cacao, coconut milk, or magnesium powders mixed with water or smoothies, with hot chocolate (made with raw cacao) and herbal teas (like nettle) also being good choices.
Aside from magnesium, almonds contain vitamin E, protein, fibre, and heart-healthy monounsaturated fats that lower cholesterol. Eggs: A staple in many diets, eggs contain magnesium and other nutrients. Each large egg contains 5-6 milligrammes of magnesium, a scarce mineral.
Achieving 100% of the daily recommended magnesium intake can be accomplished by eating foods rich in magnesium, such as:
Sardines in water VS oil: which one is better? Sardines in olive oil taste better - arguably. Sardines in water have roughly half as much fat, but the amount of saturated fat isn't a lot higher in olive oil-packed sardines. In other words sardines in olive oil have more fat, but it's the good stuff.

The unhealthiest fish to eat are typically large, predatory species high in mercury like shark, swordfish, king mackerel, and imported tilefish, plus bluefin tuna, which are dangerous for brain/nerve health, especially for pregnant women and children; also, farmed salmon and some imported tilapia/catfish raise concerns for contaminants and antibiotics, while orange roughy and Atlantic cod are often cited for high mercury and overfishing/sustainability issues.
Some of the healthiest fish include salmon, sardines, and tuna. White fish like cod and tilapia are also nutritious, but they don't have as many omega-3s as oily fish. Some fish are high in mercury, while others are overfished or endangered. It's best to eat both of these types of fish less often.
Scombroid Fish Poisoning
This including mackerel, tuna, king fish, herring, sardines, marlin, anchovies and bluefish. Affected fish often have a metallic or peppery taste. Scombroid poisoning symptoms usually start within 30 minutes of eating.
Pre-cooked pasta in sauce is one of the unhealthiest canned foods. While they might be tasty meals, the reason they have that addictive flavour is due to high levels of sugar and salt. For example, a can of Heinz Alphaghetti contains 1,490 mg of sodium and 18 g of sugar.
Washing Canned Fish Can Rinse Away Some Of Its Flavor
She did note that "if you find the oil or brine too strong, you can lightly rinse fish like sardines or tuna," but she warned us that you should "be mindful that you'll lose some of that preserved flavor."
Among the known magnesium deficiency causes are prescription medications such as diuretics, antibiotics, painkillers and cortisone, which can deplete magnesium levels in the body by impairing absorption or by increasing excretion by the kidneys.
Since magnesium plays a role in neuromuscular transmission and muscle contraction, it has been hypothesised that magnesium deficiency may predispose to muscle cramps. Thus magnesium supplements are often recommended to prevent cramps.
Bananas are the richest fruit in magnesium. If eaten dried, its magnesium content is higher. More generally, dried fruits such as figs, dates and apricots are an important source of magnesium. Recipe idea: Try a banana-spinach smoothie.
