Health Benefits of Sardines

The presence of macro-nutrients and micro-nutrients in sardines without having a high fat content makes them very useful for our body. Below are some of the most important benefits of sardines.
Prevention of Heart Diseases: Sardines are rich in omega-3 fatty acids helpful in preventing heart diseases. The omega-3 fatty acids found in them play a major role in controlling heart diseases. Research has shown that omega-3 fatty acids such as EPA or Eicosapentaenoic Acid and DHA or Docosahexaenoic Acid break down bad LDL cholesterol in the body and help in preventing heart diseases. Omega-3 fatty acids are also known to break down arterial plaque, which blocks arteries and increases blood pressure. By clearing the plaque, these fatty acids help in controlling blood pressure as well.
Prevents Blood Clots: Blood clots in the artery system can be dangerous for the cardiovascular system. Regular intake of omega-3 fats, which are found in fish like sardines, is good for the heart because it helps in reducing cholesterol and blood pressure, thereby preventing strokes and atherosclerosis.
Reduced Risk of Age-Related Macular Degeneration: Age related macular degeneration (AMD) is a condition which is usually seen among people age 50 or more Macular and retinal degeneration over the years results in loss of vision. Recent studies have shown that taking fish, particularly fish like sardines, resulted in a reduced risk of developing AMD. On the other hand, taking regular fat or saturated fat can increase the risk of developing AMD. Everything in moderation!

Anti-Cancer Properties: Cancer research has shown that the intake of calcium and vitamin D can be very helpful in preventing certain types of cancers, including colorectal cancer. Sardines are one of the best sources of calcium and vitamin D.

Strengthens Bones: As mentioned, sardines are a good source of calcium, and regular calcium helps in strengthening bones. A good amount of calcium, coupled with exercise can strengthen bones and prevent diseases, such as osteoporosis, in the future.
Healthy Immune System: Consuming sardines can help in building up the immune system. Research suggests that sardine fish oil may improve immune system by increasing the count of immune cells.
Healthy Skin: Who wouldn’t want healthy and glowing skin? The essential fats found in sardines play an essential role at the cellular level in skin cells. It not only decreases skin inflammation, but it will also make the skin more beautiful.
Insulin Resistance: Insulin resistance is one of the major factors to look for in diabetes. In cases where there is insulin resistance, the insulin produced in the body is utilized less efficiently. This, in turn, means that there is more glucose in the blood than there usually should be. Some studies have shown that insulin resistance can be reduced by consuming sardines. The protein found in sardines has shown itself to be effective in reducing insulin resistance, compared to casein protein.
Antioxidant Properties: Sardines contain selenium, which is helpful in neutralizing the free radicals and protecting the organs from damage

.Rich in Proteins: Sardines are good suppliers of proteins. Proteins are made up of amino acids, which are essential building blocks of life. These proteins that we eat are broken down into amino acids, which are used by our body to build muscles and play essential roles

Sardines – Purchase and Storage

Sardines are available in many varieties and are cheap compared to some of the other fish. Sardines are best when consumed fresh. Canned sardines can be stored in a cool place. Please check for the “best before” date on the can. Canned sardines come in a variety of flavors, such as mustard flavor, seasoned with sauce, with or without salt, and other versions. Depending on the taste, people make their own choice.

Sardine Recipes

Sardines can be baked or cooked quite easily. Cooked sardines can be served as a main dish, a side dish and can even be added to salads.
Fresh sardines can be prepared by applying a mixture of your favorite spices such as pepper, salt, garlic, lemon juice, condiments, and flavoring agents, as well as grilled or barbequed.

Sardine and vegetable salad is yet another simple Greek recipe. Take sardines and sauté them in olive oil for a few minutes. Cut small pieces of tomato, cucumber, olives and feta and add them to the sautéed sardines. Add lemon, vinegar, salt and pepper, and sprinkle parsley on the salad.

A Word of Caution!
There are certain things to remember while eating sardines in general.

High Purine Content:Sardines contain high amount of purines. Purines are basic structures that form DNA and RNA. These purines break up into uric acid. High levels of uric acid concentrations are known to put a great deal of pressure on kidneys as kidneys have to flush out excess amounts of uric acid. Purines should also be avoided in case of gout attacks.

Higher Levels of Mercury: In recent times, due to mercury-filled pollutants being released into the atmosphere and eventually finding their way into oceanic waters, the microorganisms in the ocean and fishes such as sardines invariably absorb the mercury and their consumption may result in mercury poisoning. However, in normal quantities, this should not occur.

Allergic Reactions: Sardines may cause allergic reactions in some people. Research shows that some organic compounds known as vasoactive amines such as tyramine, serotonin, typtamine, phenylethylamine and histamine are found in sardines. These can cause allergic reactions such as constriction of the muscles of the intestine, increased heart rate, headache, asthma, bronchi, constriction of blood vessels, and an increase of hypertension. In most cases, a very high ingestion of the above-mentioned compounds can result in these symptoms.
