I've heard Dr. Lustig's lecture,...Hi, Wati! I've heard Dr. Lustig's lecture, and the first hour is good. He talks about fructose, and he gives lots of biochemical evidence for what he says. I've written a couple of blog posts on fructose(<a href="http://lowcarb4u.blogspot.com/2008/07/fructose-not-as-healthy-as-it-appears.html" rel="nofollow">here</a> and <a href="http://lowcarb4u.blogspot.com/2008/07/fructose-ii.html" rel="nofollow">here</a>), and the more I learn about it, the more I try to avoid it.<br /><br />But by the end of Dr. Lustig's lecture, he drifts away from evidence-based findings and starts presenting ideas without backing them up with studies: glucose is the energy of life; lots of fiber is good for you; exercise helps you lose weight. I especially have a problem with the idea that glucose is the energy of life. Most of our tissues run more efficiently on fatty acids and ketone bodies than they do on glucose. A few tissues do require glucose for energy, but you really can get all you need through gluconeogenesis. You don't have to eat any glucose whatsoever.<br /><br />But thanks for the links. They provide some interesting "food" for thought.Stargazeyhttps://www.blogger.com/profile/09566854038842118222noreply@blogger.comtag:blogger.com,1999:blog-7890604293949783916.post-1983455789698620622010-05-12T22:25:31.644-05:002010-05-12T22:25:31.644-05:00Sorry I meant to say that Dr. Lustig recommends 5 ...Sorry I meant to say that Dr. Lustig recommends 5 macronutrients: Fibre, protein, fat, starch and sugar/ethanol (lumped together).<br /><br />CheersWatihttps://www.blogger.com/profile/07088202611536072114noreply@blogger.comtag:blogger.com,1999:blog-7890604293949783916.post-21385016440729190972010-05-12T22:15:27.240-05:002010-05-12T22:15:27.240-05:00Hello Stargazey, your speculation may be right. A...Hello Stargazey, your speculation may be right. According to Dr. Robert Lustig, fibre is very important. He recommends people to eat their carbs with fibre, ie, eat fruit, never drink the juice. Fructose, according to him, is poison and metabolised in the body the same way as ethanol. You may have known this, but you can watch his lecture: Sugar, the Bitter Truth <a href="http://www.youtube.com/watch?v=dBnniua6-oM" rel="nofollow">here</a>, or you can watch his interview <a href="http://nosurplus.com/the-politics-of-obesity-dr-robert-lustig-interview/" rel="nofollow">here</a>. It's interesting that he recommends that there should be 5, instead of 3 macronutrients, fat, protein, starch, sugar and ethanol. It's has provided me with a whole new understanding about carbs, and sugar in particular.<br /><br />By the way, I've been following your blog, and feel that you may be interested in this.<br /><br />Cheers!Watihttps://www.blogger.com/profile/07088202611536072114noreply@blogger.comtag:blogger.com,1999:blog-7890604293949783916.post-41009277155776229172010-05-06T07:46:13.428-05:002010-05-06T07:46:13.428-05:00Here's a thought based on what I learned from ...Here's a thought based on what I learned from doing this post:<br /><br />The fiber hypothesis and the carbohydrate hypothesis, taken together, might be combined into an <i>insulin hypothesis</i> that explains why primitive peoples tend to avoid the diseases of Western civilization. Groups like the Inuit, the Plains Indians and the Masai ate very few carbs and very little fiber. A very-low-carb diet does not produce insulin spikes, and fiber would not have been needed to smooth out the insulin response to the ingestion of protein.<br /><br />But native cultures that ate a higher percentage of carbohydrates were not eating refined carbohydrates like sugar, rice and flour. Their carbs had a low glycemic index and would have resulted in a slower, smoother insulin release than that seen from refined carbohydrates. The presence of fiber would have smoothed out any insulin peaks even more. The absence of insulin spikes in pre-Western diets suggests that these people would have been much less likely to have developed insulin resistance and with it, the diseases of Western civilization. That's just speculation, however.Stargazeyhttps://www.blogger.com/profile/09566854038842118222noreply@blogger.com
