※ 引述《minpanda 看板: FITNESS》之銘言： :《植物的逆襲》 https://nutritionstudies.org/the-plant-paradox-by-steven-grundy-md-commentary/ T. Colin Campbell有評論: It’s hard to turn on the TV these days without hearing about “fake news.” The proliferation of fabricated “facts” and ignored truths are a great menace to our society. As others have pointed out before, we’ve been living with fake news in consumer-level nutrition messaging for years. It doesn’t matter how many PhDs a person may have – standing in front of the nutrition bookshelf at the bookstore is a sure path to an overwhelming sense of confusion and uncertainty. Recently a new book has captured public attention, The Plant Paradox, by Steven Gundry, MD, focused on the surprising claim that lectins are the source of most, perhaps all human disease. It’s too time consuming to swat away every bit of nonsense that hits the popular media in nutrition, but we’ ve been getting a lot of questions about this book and its premise, that lectins are the true culprit of our ills. Dr. Gundry writes on his website, “I believe I’ve discovered some unconventional truths about human nutrition.” Unconventional? Yes. Truths? Not so fast. The Plant Paradox is written by an author who reminds us of his distinguished career in medicine, including his experience in research. Dr. Gundry says, “with all modesty” that he has “found there is a common cause for most health problems” and further that “it is based on ample research, including [his] own papers, published in peer-reviewed medical journals, but that no one has put it all together before.” He goes on to say that so-called “health ‘experts’ have pointed to our laziness, our addiction to fast food” etc., but according to him, “sadly, they are wrong … [and that] … the real cause is so well hidden that you would never have noticed it.” This sounds like we’ve come across quite the amazing secret, just now uncovered by Dr. Gundry. So, he wants to educate us—but about what? The first hint comes from the book’s title, “The Plant Paradox.” A reader might think, “Aha, perhaps something is wrong with all that whole grain, vegetable nonsense after all! I like this. I knew that there was a reason why I never liked veggies and why I should, instead, be eating grass-fed meat! This book is for me!” So, what, specifically, is wrong with plants? According to this book, it’s not only about that awful gluten that we have heard so much about but about a whole class of “highly toxic, plant-based proteins called lectins” of which gluten is a member. He says that “lectins are found not only in grains like wheat but also in the ‘gluten-free’ foods like … many fruits, vegetables, nuts, beans and conventional dairy products,” which “many of us regard as healthy.” After consumption, they “incite a kind of chemical warfare in our bodies, causing inflammatory reactions that can lead to weight gain and serious health conditions.” On pages 68-70, Dr. Gundry offers an enormous list of ailments that have resolved in patients following his lectin-avoidance protocol, including a huge variety of autoimmune diseases, cancer, heart disease and some of its risk factors, weight problems, slow infant growth, mental health problems, and some neurological conditions like Parkinson’s, dementia, and “cramps, tingling, and numbness.” These would be earth-shattering findings, if true. It’s particularly alarming because these findings lie in opposition to well established observations about diet and health. For one, populations who have transitioned to rich, Western diets generally adopt a diet lower in lectins. A transition to a Western diet is characterized by more meat, more added fats and sugars, and fewer beans and whole grains[1]. One of the commonalities of the blue zones, areas of long-lived populations, is that they consume legumes[2] (and Americans, by and large, don’t). Consumption of beans has been shown to be beneficial for a wide range of diseases, including diabetes[3], heart disease[4], cancer[5], and in weight management[6][7] (Dr. Gundry allows vegetarians and vegans to eat beans, but only those that have gone through a pressure cooker, and yet research demonstrating the huge array of benefits of consuming beans does not require pressure cookers). Increased whole grain consumption, compared to low whole grain consumption, has been shown to be beneficial for a wide range of chronic disease as well, including early death and death from cardiovascular disease[8]. Earth shattering findings demand extraordinary scientific evidence. It would be nice to see some peer-reviewed science that supports his astounding claims, so we took a peek through the early part of the book to see what kind of references he offers. His first big claim (pg xv) is that his findings are published in peer-reviewed medical journals. His “peer-reviewed” medical publication cited is an abstract published in the journal supplement for a poster presentation. Making a poster to display at a conference is nice, but this is a world apart from publishing actual clinical trial results in a peer reviewed journal. In other words, there is no detailed publication of his methods, his subjects, his results, or his intervention as would be commonly expected in a normal publication. His glowing description of this abstract is misleading, to put it mildly. -- 「你要專心仰賴耶和華，不可倚靠自己的聰明，在你一切所行的事上都要認定他，他必指引你的路。」（箴言3:5-6) -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 111.243.58.168 (臺灣) ※ 文章網址: https://www.ptt.cc/bbs/FITNESS/M.1568293479.A.D44.html
