Doctor's Note

For the role of saturated fat in breast cancer survival, see yesterday’s video. When the dietary guidelines recommend keeping intake of trans fat as low as possible, what does that mean on a practical level? See Good, Great, Bad & Killer Fats and Trans Fat, Saturated Fat and Cholesterol: Tolerable Upper Intake of Zero. Nice to see public health trump corporate interests. See Dietary Guidelines: USDA Conflicts of Interest for one of 25 videos I have on the guidelines. And if that isn't enough, there are hundreds of other videos on more than a thousand subjects.

    I’m really confused about soy. Especially when I see videos like these: http://www.youtube.com/watch?feature=player_detailpage&v=0uIn2L90wA8

    Can you do a huge video on soy or maybe point me in a direction that confronts these sort of claims.

      luvmy2pugs:  I’m late to this discussion, but I wanted to directly reply to your question. 

      “wilscot”‘s answer was so helpful to me, I”m sure you found it helpful also.  However, Dr. Greger does have quite a few videos that specifically deal with soy and were also extremely helpful.  There may even be a blog or two on the subject. 

      There are more videos than I want to list here, but I highly recommend that you use the search box at the top right of the screen to see what Dr. Greger has already done on the subject. 

      Good luck.

    Dr Greger would be able to provide a more expert reply regarding soy, but in the meantime I’ll make a few comments:
    Mercola is not well respected by the scientific or medical community and has got into trouble in the past for making inflated claims. He is against soy for the following reasons:
    – Most of it is GM – Response: if this bothers you choose organic
    – it has goitrogens which interfere with thyroid function – Response: my understanding is that this is only a problem in people who are low in iodine – so just make sure you are getting enough of this nutrient
    – it is estrogenic – Reponse: the science on this issue is so much more complex than Mercola indicates. On balance, soy isoflavones appear to be selective estrogen receptor modulators that may reduce estrogen levels where this is helpful (cancer) and boost them where helpful (bones and cognitive function). Three recent studies on breast cancer survivors have all found that soy intake was associated with better survival – that is the just about the best evidence you are going to get of its safety.
    – phytic acid – lots of high fibre whole foods have phytic acid. It can reduce nutrient absorption, but it is also thought to be a powerful antioxidant. Just make sure you eat a high nutrient density diet, and the phytic acid won’t be a significant problem and may be of benefit.
    – soy products contain MSG – well – check the labels – I can’t say I have ever seen this.
    There is a lot of web based paranoia demonising soy – it’s just a food, and like all foods has some pros and cons, but unlike some foods, the pros outweigh the cons.

      Very well said!

    This is very helpful. I have only recently taken interest in nutrition and started following a whole, plant based diet two months ago. Despite being normal weight, my blood pressure was terrible prior to trying the new diet. I used to believe that veganism was less healthy and that soy was terrible for you. Only recently have my eyes opened. Thanks to the diet changes my blood pressure is normal now despite my awful genes(something I thought I couldn’t control, both parents had high BP). That tells me I’m on the right path, but soy has been rough to figure out! Again, thanks for the info.

      I tend to find that Dr. Mercola is quite radical in his views and misconstrues evidence.
