DESCRIPTION: The relationship between fish consumption and diabetes risk may be due to toxic pollutants that build up in the aquatic food chain.

This is the first of a 3-part video series on the role industrial pollutants may play in our diabetes epidemic. Stay tuned for Diabetes and Dioxins ( ) and Pollutants in Salmon and Our Own Fat ( ).

More on the changing views surrounding fish oil supplements in Is Fish Oil Just Snake Oil? ( )

Other foods associated with diabetes risk include processed meat and eggs. See Bacon, Eggs, and Gestational Diabetes During Pregnancy ( ) and Eggs and Diabetes ( ), while Indian gooseberries and flaxseeds may help (Amla Versus Diabetes, and Flaxseed vs. Diabetes, ).

Other videos on how polluted our oceans now are include:
• Fukushima and Radioactivity in Seafood ( )
• Food Sources of Flame Retardant Chemicals ( )
• DDT in Umbilical Cord Blood ( )
Food Sources of Perfluorochemicals ( )
• Fish Intake Associated with Brain Shrinkage ( )
• How Long to Detox from Fish Before Pregnancy ( )

    So very disturbing. There a lot of people here in the PNW who eat fish but who are on otherwise plant based diet. Same in the Caribbean as well! 🙁

  • Meta Patriot says:

    I’m calling Greger out on this one Omega-3 fatty acids increase insulin sensitivity, which helps to lower blood sugar levels. In the long term, this reduces insulin resistance, lowering blood sugar levels. Fish oils also reduce inflammation, which is a major factor in diabetes. so why the concern with fish? why not flax seed? Weight gain, especially abdominal fat along with little or no exercise increases the risk for Type II diabetes. In addition, these foods may increase the risk: Fast Foods: two or more fast food meals per week increases diabetes risk Trans Fats: trans fats increase inflammation, insulin resistance and elevate blood sugar levels Soft Drinks: each soft drink increases diabetes risk 60 percent.

  • elite1980s says:

    As the oceans are becoming more toxic through pollution like oil spills and radiation even heavy metals from the industrial complex, eating fish is becoming more risky. Tuna now days has twice the amount of mercury than ten years ago. Btw Monsanto experimented with agent orange in forests of Puerto Rico prior to using it in Vietnam. Now days they use depleted uranium in tank shells to reduce the life expectancy of people in the world (soldiers like surveillance).

    Why does fish consumption appear to increase diabetes risk even more than red meat?

  • mele host says:

    You would have to compare with long term effects of not eating meat or fish, compared to meat eaters and those that abstain for a short period for test purposes.

  • reinux says:

    Any word on what kind of fish it was?
    From what I understand, longer-lived fish are worse, because pollutants can bioaccumulate.

  • Jack Carroll says:

    I have been having a worry over the last few days that I might be a diabetic I have the tingling in my legs but that is the only symtom my family only have 1 person who had diabetes I hardly eat much only once a day but remain inactive and drink sugary drinks and sweet deserts like milky way

  • Magnum Build says:

    great message. good research…dont hate the doc for reading research…

  • The storm is letting up says:

    Guys relax.. although it seems like were all doomed to just eat air with all these findings, I think this analysis needs to be more accurate. Just eating fish twice a week? I think the kind of fish, it’s origin, and yes that’s also important in toxicity levels, you’re consuming has a HUGE impact on your body ( sardines vs tuna). I think it could be a little misleading but at the same time if you are eating farmed or atlantic salmon you are eating a range of toxins and parasites so I can see how eating that just twice a week can promote diabetes. Your liver just takes a beating every time you eat shitty fish. Do your research, be very picky about the fish you eat.

  • Mac Apple says:

    But okinawans japanese, koreans, chinese and most asian countries would say otherwise because they eat a lot of fish and seafoods (tuna, mackerel, herring, sardines, shrimps, crabs, octopus, fish roe, milkfish, tilapia, red snapper and shellfish).

    • M. Bison says:

      You must be new here…..the traditional Okinawan diet is 96% vegan, only 1% of it is fish. Okinawans have the 2nd longest lifespans next to VEGAN ADVENTIST which beat literally every asian country you mentioned. Also dairy consumption is overall extremely low in Asia which profoundly affects diabetes rates .

    • Suchitra Colonne says:

      @M. Bison what about Indians, most of them are vegans and still diabetic. Pls explain


    Salamat po ng marami sa tips na binabahagi nyo,

    Dear sir, Only good sleep can stop sugar and pressure.

  • Suchitra Colonne says:

    I think more we listen to people more we get confused. Some say let’s diet, low carbs, vegan, vegetarian.. All sort of diets.. And we listen to all of them and are becoming masters of all diets.
