Adding more fish to your diet might lower your risk of colorectal cancer, according to a new meta-analysis. The researchers reviewed 41 studies in which fish consumption had been recorded. People who ate the most fish were 20 percent less likely to be diagnosed with rectal cancer than those who ate the least. The investigators caution that the study does not show how much fish is enough and how it should be cooked.

    Is it true that farm raised fish may are fed corn products that are stored in silos which are also sprayed with pesticide and in turn are contained in the fish? Is the water really clean enough for farm raised production meaning that they most likely eat left over residue and waste products in the water versus wild caught fish?

    I, too, would be interested in your opinion as to how fish oil supplements might compare to consuming actual fish. I try to do both but often fall short on the actual fish-consuming. Always take a high-quality supplement, though.

    >The type of fish doesn’t matter
    Beg to disagree here. Wild-caught fish eat foods that generate high levels of the Omega 3 oils. Farm-raised fish are fed corn-based food, and do not contain the same levels of Omega 3, which is the likely source of the benefit from eating fish in the first place.
    Agreed, deep-frying cancels any benefit you will get from either version.
    Most of these dietary studies are long-term enough that farmed fish wasn’t a major factor in the beginning. It is now.
    It’s the same as grass-fed vs corn-fed beef. Completely different fat profile. Corn feeding is the problem, not the meat itself.

    Does this information regarding fish consumption hold true for canned sardines as well? And if so, are sardines packed in oil preferable to sardines packed in salt water?
    PEOPLE’S PHARMACY RESPONSE: Yes, sardines are a good source. For this purpose, it doesn’t matter whether they are packed in oil or in water. Pick what you like, unless you are counting calories. (In that case, water is better.)

    How much fish? What kind of fish? We eat fish once a week but really don’t care for it and smother it in onions/garlic/ginger. Would we be just as well off to take fish oil? thanks
    PEOPLE’S PHARMACY RESPONSE: Two or three times a week are thought better than once. The type of fish doesn’t matter as much as not preparing it by deep-frying it. Onions, garlic and ginger sound great, with benefits of their own along with the fish.
