Why Diabetic Tuna Recipes Should Not Be Used Too Often
Fish should be on your menu at least twice a week if you have diabetes. Certain fish species such as salmon and herring as well as tuna contain the so-called heart-healthy omega-3 fatty acid which promote heart health and reduce the risk of cardiovascular disease. Despite the fact that canned tuna is one of the best sources of this heart-healthy fat, diabetic tuna recipes should not be used too often.
As you most likely already know, tuna does not contain only omega-3 fatty acids and other important nutrients but it also contains mercury. Unfortunately, this is not one of the urban legends and eating tuna in larger amount too often could pose certain health risks. And mercury is present in just about all can of tuna regardless of the brand, while larger tuna species such as albacore tuna for instance are even higher in mercury content. But considering that it is considered safe for pregnant women to eat up to 12 ounces of canned light tuna and 6 ounces of albacore tuna, it cannot hurt if you stick to these guidelines. After all, if they are safe for pregnant women they should be safe for the rest of the population as well.
Despite relatively high mercury content, you can continue to enjoy your favourite diabetic tuna recipes without jeopardizing your health. However, it may also be a good idea to consider including other fish species into your diet which are just as good or even a better source of omega-3 fatty acids but are relatively low in mercury content. Examples include the above mentioned salmon, while a good choice are also herring and pollock. Large fish species such as shark, swordfish, tile fish and king mackerel, on the other hand, are even higher in mercury than canned tuna and should be on your menu even less frequently.
If you do not like fish or worry about the effects of mercury content in tuna on your health, you should perhaps consider using fish oil or fish oil capsules. Both contain the heart-healthy omega-3 fatty acid and a high level of antioxidants which offer protection against the effects of the free radicals that are believed to be responsible for a number of diseases including cancer. Fish oil and fish oil supplements are of course made from fish as well including species which are high in mercury, however, most manufacturers remove mercury and other contaminants with special purifying process.
