Plans for large-scale AIDS vaccine trial dropped (AP)
AP - Plans for a large-scale trial of a potential AIDS vaccine are being dropped in favor of a smaller, more focused study, the National Institutes of Health said Thursday.
One of the most common questions that gets asked when someone is considering taking fish oil capsules is whether they will get the same benefits as they would from eating fish. This article will explore some of the differences between eating fish and taking a fish oil supplement.
According to a recent study in the December 2007 issue of the American Journal of Clinical Nutrition, there is no difference in how the body reacts to fish and fish oil. The researchers compared two groups of women -- one group ate two servings of fish a week; the other group took supplements instead. In both cases the effect of the fish oil on their bodies was the same regardless of its source.
Many people researching their decision would just stop at that, believing that it doesn't matter whether they eat fish or take supplements. But there are differences between the two that need to be considered.
First, the amount of oil you will get from eating fish is dependent on factors such as what type of fish, how it's cooked, and how much you eat. Add to that, different species have varying types of omega 3 fatty acids, most notably EPA and DHA. If you are using the fish oil for a specific treatment, then capsules containing a pre-determined combination of oils may be the better choice for you.
Another difference between fish and fish oil capsules is contamination and pollution. Many of the fish species that are good sources of omega 3 fatty acids are also prone to mercury contamination and other types of pollution. In contrast, the oil that is put into capsules has usually gone through some type of purification process to remove any contaminants.
And finally, there is the difference of taste. Some people just don't like the taste of fish, no matter how good it is for their health. Most supplements have no taste at all, or are flavoured with a fruit taste such as lemon in order to avoid the fishy aftertaste.
Even though there is, so far, no medical difference between eating fish and taking fish oil capsules, there is still the matter of personal differences. Whichever you choose, you will be doing your body a favour by providing it with the omega 3 acids that it needs for optimum health.
