Something Fishy. Something Hearty.
Fish oil has already been proven to reduce the risk of some types of cancer mainly because of the high levels of omega-3 fatty acids that it contains. Aside from cancer, fish oil is also beneficial in treating certain skin problems, joint pain relief and other rheumatoid problems. Certain studies have also concluded that it can possibly ward off Alzheimer’s Disease. However, it seems that fish oil does not cease to be promising up until this point only. It has also been studied to have effects against risk of heart ailments as well.
Several studies have been conducted with people who have already been diagnosed with heart illnesses. The first of these studies was conducted by Italian researchers on 7,000 patients where half of them were given daily omega-3 capsules while the other half was given a placebo. The second research was actually a parallel study that used Crestor. All of them were being tracked as they were still on their previous medication. After several years of tracking the patients, results have shown that omega-3 is slightly more effective than normal drugs that people with diagnosed heart failure take. The effect of omega-3 is actually related with a long term intake of at least 1 gram daily. This has shown a decrease in mortality and hospital admissions for coronary-related illnesses. These were synthesized results from two studies. This was concluded from one of the studies led by Professor Luigi Tavazzi. Professor Tavazzi does research work with the Italian Association of Hospital Cardiologists.
This whole idea might still go back to how certain solutions to heart illnesses can be natural rather than artificial. The effects of these studies, even though treated with some ambiguities because of a lack of direct comparison, can influence advice given to people who are being treated for heart problems. Whether they take in food supplements or capsules with omega-3 or simply increase their intake of fish, this still has to go through their physicians. Normally, people are advised to eat fish twice a week.
Given the complexities of treating heart failure, it is still advised that patients who decide to alter their diet consult their doctors first. In certain cases, the fish oil may not be good for people who have heart failure and high cholesterol. This was noted by Dr. Gregg Fonarow in an editorial with the journal article regarding these findings. Despite the fact that these can be taken from natural sources, people taking them in should still be monitored because they used a specific formulation for the studies.
Aside, of course, from fishes, good sources of omega-3 would be other seafood like oysters, crabs, and prawns. For those who are looking into a diet with less seafood and probably vegetarian, one can get a good amount of omega-3 from walnuts, spinach, broccoli, and cauliflower. However, natural, nowadays, is not necessarily that healthy as we would want them to be. It is still advised that one check the sources of these foods. For the seafood, one still needs to be wary of mercury poisoning or contamination to polychlorinated biphenyl or PCBs. But you can always get capsules and supplements from drug stores.
