<p>On fiber:</p>
<p>Unlike some, Lustig doesn’t seem to be saying that fiber has any particular health benefit beyond its ability to slow the absorption of sugar and/or carbohydrates. He believes that the problems arise from hitting the liver (especially) with a big shot faster than it can be processed. So, by consuming sugar and carbs with fiber, it is absorbed over a longer period of time. So I would infer that he’s not so concerned with the total fiber number as he is with eating it along with servings of sugar or carbs. He’s also realistic in what he can get people to do dietwise, so he’s attacking the big monsters in the diet: sugar and and refined junk carbs and recommending just eating real food will get you in the ballpark (hard to argue with that!)</p>
<p>I don’t really know where the USDA got it’s daily recommended fiber numbers, but I have no reason to believe that they are any more reality-based than the other USDA recommendations! My personal (admittedly cynical) view is that, if the USDA publishes a dietary recommendation, it’s probably wrong and probably bought and paid for. Not coincidentally, the shelves of my grocery store make it pretty obvious that a lot of money is being made pitching “High Fiber” products (including, I believe, [Honey</a> Nut Cheerios](<a href=“http://whatsyourmodotorg.files.■■■■■■■■■■■■■/2013/01/honey-nut-cheerios.jpg]Honey”>http://whatsyourmodotorg.files.■■■■■■■■■■■■■/2013/01/honey-nut-cheerios.jpg), which claim to lower cholesterol and reduce the risk of heart disease based on their fiber content ). So, right there is a vested interest in pitching fiber. Pretty clever way of making anyone believe that Honey Nut Cheerios is good for you – a product that is 32% sugar by weight. Not to be tin-foil hat about it, but I consider the USDA to be an active participant in deceptive marketing.</p>
<p>Having said that, I haven’t read a shred of harm that can come from too much fiber (within reason), so I do try to keep my fiber up. I wash down two fish oil caps twice a day, before lunch and dinner, with a glass of psyllium husk fiber. It’s the water soluable fiber that is commonly added to products like “whole grain” bread and “whole grain” cereal to make them “high fiber” since they really aren’t “whole grain”. Basically Metamucil, except I buy a sugar-free, flavor-free version at GNC. That’s an added 10 grams of fiber per day, so with the amounts of veggies, lettuce, and fruit I eat, I can usually get to 20-25 grams a day. I got to 30 yesterday with a big serving of lima beans for dinner.</p>
<p>10g GNC Colon Pure Purified Psyllium Husk
05g Blue cheese salad for lunch
10g Baby Lima Beans
05g Fuji apple (Super Bowl splurge!)</p>
<p>I don’t know if the fiber and fish oil really does any good or not. But, it has coincided with good results in terms of weight and blood work, so I might as well keep at it. As an added bonus, the fiber makes me chug two good size glasses of water each day, which is not a bad thing.</p>
<p>If there is a link between metabolic syndrome/insulin resistance and colon cancer and if Lustig is right about the cause and prevention of insulin resistance, then right there is the mechanism for fiber’s benefit lowering colon cancer rates (and lowering heart disease and cholesterol and diabetes…).</p>
