Doctor's Note

I addressed this issue previously in videos such as:

Isn’t it illegal to sell meat contaminated with dangerous bacteria? Unfortunately no. See why in my video Salmonella in Chicken & Turkey: Deadly But Not Illegal. Reminds me of the case I wrote about in Supreme Court case: meat industry sues to keep downed animals in food supply.

    I am hoping someone can tell me if the resveratrol in red grapes is degraded or eliminated when cooking? My friends tell me that the pasteurized organic grape juice I sometimes drink has no resveratrol remaining due to the heat of pasteurization. For some reason I am a bit skeptical.

    • Phil

      Your friends are correct; little or no resveratrol remains after pasteurization. But the point is moot since grape juice has such a small amount in it to begin with. To get the amount that Sinclair used in his experiments would require you to drink hundreds of bottles of wine a day. What a headache you’d have!

      (continued from below) Don’t think you need to take 250mg of resveratrol to get the benefits found in experiments. The drug worked by activating the SIRT1 gene. You can get the same effect by intermittent fasting. There are two versions of this regimen. You can either limit your calorie intake to 500 calories a day and then eat as much as you wish on alternate days (and probably loose quite a bit of weight) or you can simply eat each day during an eight hour window, say from noon to eight. One gets used to skipping breakfast, but not to alternate day dieting. Of course, if you’re already on a low fat diet, you may not get additional benefits from resveratrol at all.

        Interesting information, Phil. I recently instituted an 8-hour feeding window regimen noting your reference in the comment above (after initially hearing of the concept in the Perfect Health Diet book). It seems to be going just fine, but I would love to see some more information on the benefits, effects, etc. The effect you reference seems interesting, but previously unknown to me. Might you know of any information sources? Thanks.

        When you said “if you’re already on a low fat diet, you may not get additional benefits from resveratrol at all.” What does low fat have to do with resveratrol? This is new to me.

      • guest

        I too would like to know why if you are not on a low fats diet then the resveratrol would include no benefits.

        can’t see how one would not receive benefits from resveratrol if on a low fat diet. It is true that a diet high in omega-6, transfats and hyrdrogenated fats increases inflammation and free-radical damage. Resveratrol may help to reduce some of the damage. But, people not eatting as much damaging fat can also benefit. Personally, I like to make sure I have adequate fat in my diet – minus 2 of the damaging ones that I mentioned and higher omega-3 to omega-6 ratio.

    “Use of antibacterial agents creates selective pressure for the emergence of resistant strains.” FC Tenover, …. so remove the selective pressure (i.e. use antibiotics sensibly) and the baddies revert, no more superbugs. Food science marches on.

    So interesting. Thanks Dr. Greger!

    It frustrating that the United States hasn’t taken strong leadership on this. Everyone is so afraid of Big Agribusiness.

    It would be great to see the data on organic vs conventional vs free range on more than just Beta lactamase stuff.

    Are you going to cover “superbugs” in vegetables too?

    For a real world perspective, chicken for example is usually eaten cooked – maybe not perfectly handled, but cooked nonetheless. Many contaminated vegetables on other hand are often eaten raw. Thus the actual risk of exposure to antibiotic resistant bacteria may be higher from vegetables or fruit than from meat.

    “Overall, consumption of raw vegetables represents a route of human exposure to antibiotic-resistant bacteria and resistance determinants naturally present in soil.”

    good reason to buy all food from farmers we know or grow our own. The organic vegetable farms are also contaminated by manure run-off from factory farms.
