If you have diabetes or are currently overweight, there are several studies that suggest that eating fish is a very good thing for you.
One study we reviewed, which was conducted by Louisiana State University, showed that populations that eat a lot of fish containing omega-3 fatty acids – like tuna, salmon and mackerel – have lower rates of Type 2 diabetes compared to those populations who eat less fish. They then looked at the effect of omega-3 fatty acids and how our body uses insulin. The results were amazing.
According to researcher Dr. Yvonne Denkins in 2002, “after 12 weeks, researchers found that 70% of the participants showed a decrease in insulin resistance, and in 50% of the patients that change was significant.”
At melslife, we look at every study with suspicious eyes. We never really know for sure who funded the study, what criteria was used, were the subjects honest with the researchers, and so on.
What we do know is that fish is a nutrient-dense food and an excellent source of protein, vitamin B12 and iron. If you have diabetes, fish is not going to hurt you. Fish should be part of a balanced diet.
If you are trying to lower your bad cholesterol, improve your blood pressure and have a healthy heart, fish is great for you. Seafood is one of the most nutritionally balanced foods.
Cold-water fish like salmon, tuna, mackerel and halibut are full of omega-3 fatty acids. These are probably the best fish for lowering your cholesterol and high blood pressure.
Omega-3s have been shown to lower triglycerides, a type of fat in our bloodstream, and help keep our bodies from over-producing eicosanoids, a group of hormone-like substances. Omega-3 fatty acids may also slow down the growth of plaque in our arteries and reduce inflammation.
The American Heart Association reviewed the benefits of fish and fish oils and concluded that they help prevent cardiovascular disease, including fatal and non-fatal heart attacks, strokes and coronary artery disease. Fish oils are beneficial for the following reasons:
We are not doctors, but all of the above sound good to us. If you want to have a healthier heart, lower your cholesterol and live with your diabetes, eat more fish.
Some wild fish – like swordfish, shark and mackerel - may contain harmful toxins because of their water environment. Try eating these fish in moderation, if at all. Nursing mothers, pregnant women and young children should not eat these fish, or at the very least, consult your doctor or nutrition expert.
