Omega-3 fatty acid toxicity

For other environmental factors, the associations with autoimmunity have been suggested from epidemiologic studies and/or animal models or in vitro studies. Dietary factors such as iodine, nutritional supplements such as omega fatty acids, and food contaminants such as those found in the cooking oil associated with toxic oil syndrome have been linked with autoimmune disorders. Table 32.9 lists a number... 

Potential protective effect of selenium in fish. Selenium is known to bioconcentrate in fish, and selenium has been observed to correlate with mercury levels in the blood of fish consumed (Grandjean et al. 1992). Furthermore, there is evidence suggesting that consumption of methylmercury from fish, in conjunction with other beneficial constituents in fish (e.g., omega-3 fatty acids) may not result in the same toxicity dose-response relationship observed with methylmercury exposure from consumption of contaminated grain (as in the Iraqi population) (Davidson et al. 1998). 

But don t take too much vitamin D. More than 2,000 units daily for six months can raise blood-calcium concentrations to toxic levels. So unless your doctor tells you otherwise, keep the supplement dose to about half that. Or you could hold your nose and gulp down a tablespoon of cod liver oil. With 1,360 units of vitamin D (and lots of brain-healthy omega-3 fatty acids ), it s more than enough to jump-start your day. 4...
