When it comes to maintaining a strong immune system, what you eat can directly impact your body’s ability to stave off illnesses such as multiple sclerosis and lupus. For younger women of childbearing age specifically, consuming seafood high in mercury has been shown to increase the risk of autoimmune difficulties, a consequence of immune cells attacking healthy tissue. These illnesses primarily affect women, with a whopping 50 million Americans suffering from various forms.
The Search for an Explanation
One of the difficulties in addressing autoimmune disorders is the lack of a clear understanding of what triggers their development. Genetics do not account for a substantial number of cases, leading researchers to wonder if environmental factors might play a role. In a study conducted at the University of Michigan, mercury exposure was identified as a major risk factor for autoimmunity among women.
Autoimmune diseases such as rheumatoid arthritis, lupus, inflammatory bowel disease, Sjorgen’s syndrome, and multiple sclerosis are ranked among the top ten causes of death among American women. Clearly, identifying and mitigating the risks associated with these conditions is crucial.
Seafood to Watch Out For
While seafood can be a valuable source of protein and healthy fats, certain types are also known to contain high levels of mercury, making them potentially dangerous, especially for women in their childbearing years. The types of seafood you should avoid or minimize in your diet include king mackerel, swordfish, and tilefish. To enjoy the health benefits of seafood without the dangerous mercury content, try consuming safer options such as salmon, shrimp, and canned light tuna.
Findings from the National Health and Nutrition Examination Survey
The University of Michigan study in question analyzed health information from the National Health and Nutrition Examination Survey for women aged 16 to 49 conducted between 1999 and 2004. The results of this examination revealed that women exposed to higher levels of mercury through their seafood consumption were more likely to have elevated amounts of autoantibodies—immune cells which can attack the body’s own tissues. It is this buildup of autoantibodies that often precedes the development of an autoimmune disease.
While it’s important to note that the presence of autoantibodies does not definitively mean an autoimmune disease will develop, they are known to be significant predictors of future autoimmune disease. They can potentially predate the appearance of symptoms and associated diagnoses by several years. As women of childbearing age are at an increased risk of developing autoimmune diseases, being mindful of seafood consumption is essential for maintaining optimal health.
Making Informed Choices
While seafood can be a great source of lean protein and essential fatty acids, it’s important to be aware of the potential dangers associated with certain types of fish. By choosing seafood options low in mercury and moderating your overall consumption, you can minimize your risk of developing autoimmune disorders and maintain a strong, healthy immune system.
For further information and guidance on choosing the right seafood, consult resources provided by the FDA or Environmental Working Group. These organizations can provide up-to-date information on mercury levels in various types of seafood and help you make the best choices for your health.
