Sardines: Health Benefits and Nutritious Aspects Explored
Sardines, small oily fish, are not only a delicious addition to your diet but also a powerhouse of essential nutrients. One of the key benefits of sardines lies in their rich content of omega-3 fatty acids, which are crucial for maintaining heart, brain, joint, and eye health.
Omega-3 Benefits: Heart, Brain, Joint, and Eye Health
Omega-3 fatty acids, specifically EPA and DHA, found in abundance in sardines, offer several health advantages. For instance, they help lower triglycerides, reduce blood pressure, decrease inflammation, and may reduce mortality and severity of heart disease.
In the brain, EPA and DHA maintain cell membrane health, improve cognitive function, support mood regulation, and may reduce age-related cognitive decline. Omega-3s also counteract chronic inflammation linked to many lifestyle diseases, improving joint flexibility and reducing stiffness.
Moreover, DHA plays a vital role in maintaining healthy vision and retinal function.
Recommended Daily Intake
Authoritative guidelines suggest consuming at least two servings of fatty fish per week, such as sardines, to provide roughly 500 mg to 1,000 mg of combined EPA and DHA daily on average. For those not meeting this requirement through their diet, omega-3 supplements can be a viable alternative, typically providing 250–500 mg of EPA and DHA daily.
Other Nutrients in Sardines
Besides omega-3, sardines are a good source of other nutrients essential for healthy bones, such as vitamin D, magnesium, and phosphorus. They are also an excellent source of vitamin B12, with a 100-g serving containing almost four times an adult's recommended daily allowance (RDA) of this vitamin.
Sustainable and Versatile
When it comes to sustainability, the Monterey Bay Aquarium Seafood Watch recommends avoiding the European pilchard, often referred to as a sardine, as it may not be ecologically sustainable. However, sardines, in general, are a sustainable seafood choice.
Sardines make a healthful quick lunch when added to a salad, served on toast, or put in a pasta dish. With their versatility, they can easily be incorporated into various meals.
Cautions and Considerations
It's worth noting that omega-3 can interact with anticoagulant medications, such as warfarin. Additionally, the FDA recommends consuming no more than 3 grams per day of EPA and DHA combined.
Selenium, an important antioxidant, is also present in sardines. An adult's RDA for selenium is 55 micrograms per day, and a 100-g portion of canned sardines in oil contains 68 micrograms of this mineral.
Lastly, the Environmental Protection Agency (EPA) advises that fish low in mercury is important for developmental and health benefits for females aged 16-49 years old, pregnant and breastfeeding people, and young children.
In conclusion, incorporating sardines into your weekly diet can provide a beneficial dose of omega-3 fatty acids and other essential nutrients, supporting your overall health and well-being. With their versatility and sustainability, sardines offer a quick, easy, and healthy meal option.
