Seafood choice has always been a kind of food that is favored by almost everyone. Besides delicious taste, seafood is also an excellent source of protein. Even better when compared with other protein sources derived from land or freshwater.According to the type and origin, seafood is divided into two groups. The first group, still called seafood, consisting of various types of fish. The second group is called Shellfish, who live in the ocean, beaches, and estuarium (estuary of the river). Meals are included in the group Shellfish shellfish, mollusks (such as sea cucumbers), the group crustacean (shrimp and crab), and squid-cumian. In general, it can be referred to by the term "seafood" only.
Healthy benefits
Complete amino acid content makes a very rich seafood nutrition. One of the most famous nutritional polyunsaturated fatty acids like Omega-3. In addition, seafood is also rich in vitamins and minerals. Not surprisingly, many studies prove that the seafood can reduce the risk of various diseases such as coronary heart disease, high blood pressure and cancer. New research published in the journal Diabetes Care in February 2010, states that fish consumption can provide protection against the risk of diabetes.
Another study released by the British Medical Journal in 2002 revealed that pregnant women with less intake of omega-3 fatty acids from deep sea fish, have increased risk of preterm delivery and birth weight less. To be healthy benefits of seafood will be maintained, we must understand the intricacies of the selection, processing, and how to eat.
Mandatory every week
Currently, a lot of seafood contaminated with methyl mercury (organic mercury). Pollution levels at each marine animals vary, depending on the environment, age and nature of the predators. Large and long-lived predators such as shark and marlin, more exposed to mercury compared with the short-lived small marine animals like shellfish and shrimp.
Seafood contaminated with mercury can cause poisoning. Symptoms of mercury poisoning in adults were tingling, and balance disturbances and sensory disturbances of the body. In fetuses, mercury can cause developmental delay and neuromuscular cognition. While the negative effects of mercury exposure to low levels of long-term, until now still not clear.
Besides mercury, there are also suspicions that many marine animals are contaminated industrial waste chemicals (PCBs, or polychlorinated biphenyls). Actually, this compound was not allowed to circulate again, but contamination still occurs today. Aka carcinogenic PCBs can trigger the growth of cancer cells.
Fortunately, the Journal of the American Medical Association in 2006 stated that our risk of cancer due to eating seafood is still very small when compared with healthy benefits that we will get.
So, it could still make as much seafood as a compulsory menu 1-2 servings per week. What is important, consider the type of seafood that we will though. Do not choose a large contamination levels, especially for women who are pregnant.
