Again they found no reductions in the group on calorie restriction. "That was puzzling because it was the first time we hadn't seen agreement between mice and rats on calorie restriction and humans on calorie restriction," Fontana explains. "But we know there are two major influences on IGF-1 levels: calorie intake and protein intake. So we decided to look at the influence of protein." Again, Fontana had a ready-made study group. His team has been following a population of strict vegans for several years. They tend to eat less protein than the CRONies from the CR Society, so he compared IGF-1 levels between the two groups. "The vegans had significantly less circulating IGF-1, even if they were heavier and had more body fat than CRONies," he says. "Protein in the diet seemed to correlate with the lower levels of IGF-1. The strict vegans took in about 10 percent of their total calories from protein, whereas those on calorie restriction tended to get about 23 or 24 percent of calories from protein." http://www.eurekalert.org/pub_releases/2008-09/wuso-rnd092408.php Thu, 25 Sep 2008 16:15:59 GMT http://www.eatqod.com/forum/viewtopic.php?f=8&t=244&p=711#p711 EurekAlert: They found that 29.1 % of cases had tumors with at least one methylated gene promoter. In case-case comparison, no significant association was found between methylation in tumors and any single genotype. However, in comparison to controls with the CC genotype, an increased risk of tumor methylation was associated with the CT genotype (OR = 2.5; 95%CI, 1.1 - 5.6). In case-case comparisons, folate/vitamin B12 was positively associated with tumor methylation. Adjusted odds ratios for tumor methylation in cases with high (above median) versus low (below median) serum folate/vitamin B12 levels were 4.9 (95%CI, 1.4 - 17.7), and 3.9 (95%CI, 1.1 - 13.9), respectively. The frequency of methylated tumors was significantly higher in high methyl donor than low methyl donor group, especially in those with MTHFR CT (p = 0.01), and CT/TT (P = 0.002) genotypes but, not in those with the CC genotype (P = 1.0). The results from this study indicate that high concentrations of serum folate/vitamine B12 are associated with the risk of promoter methylation in tumor-specific genes, and this relationship is modified by MTHFR C677T genotypes. These results support other recent reports that high folate and vitamin B12 status might serve as risk factors for CRC. http://www.eatqod.com/forum/viewtopic.php?f=8&t=244&p=711#p711 Thu, 25 Sep 2008 16:14:00 GMT http://www.ajcn.org/cgi/content/abstract/88/3/667 AJCN: Cognitive performance, activity, sleep, and mood are not adversely affected in healthy humans by 2 d of calorie-deprivation when the subjects and investigators are unaware of the calorie content of the treatments. http://www.ajcn.org/cgi/content/abstract/88/3/667 Sat, 13 Sep 2008 17:06:16 GMT http://www.eatqod.com/forum/viewtopic.php?t=151 A paper appeared in December of 2006 from Fontana's group, showing that being on a diet for 1 year in non-obese people resulted in a measurable loss in bone density. Losing the same amount of weight by exercising was not associated with a loss in bone density. Again this is why we're very cautious about following the QOD diet, or any diet, for a prolonged period of time. Exercise is a required component. And QOD should not be used as a lifestyle diet in the hope of prolonging longevity. The risk - benefits of this approach are as yet unknown. Certainly one needs to take calcium and magnesium EVERY day, and get adequate vitamin D stores. Perhaps reduction of fats may also be involved in the dieters. This whole issue needs to be better studied. http://www.eatqod.com/forum/viewtopic.php?t=151 Tue, 12 Dec 2006 18:49:34 GMT http://www.eatqod.com/forum/viewtopic.php?t=127 This is a fresh approach to the dieting question by a marketing research professor. The book is a fascinating read and witty and fun to boot. See the link for more information on Dr. Wansink's basic ideas as to how we can control our food intake to prevent becoming obese. http://www.eatqod.com/forum/posting.php?mode=newtopic&f=9 Sat, 11 Nov 2006 22:14:56 GMT http://www.eatqod.com/forum/viewtopic.php?t=122 Dieters should always be careful about their bone density. Particularly if they are people who lose a lot of calcium in the urine. I think we pretty much all should be taking in 600 mg/day of calcium plus 1,000 (some say even higher) IU of vitamin D per day. There is also evidence, though that the acid produced by certain foods that we digest can leach away our bones. Atkins dieters need to pay attention to this, and switch more to milk and/or egg white as opposed to meat as the main source of protein. For a discussion of this, see the above paper just published in October of 2006. How to assess the acid content of food is tricky and controversial. One method is the PRAL method - see the Forum post for more information and a link. http://www.eatqod.com/forum/viewtopic.php?t=122 Fri, 03 Nov 2006 11:26:25 GMT http://www.eatqod.com/forum/viewtopic.php?p=178#178 Independent (UK): Dr James Johnson, who co-wrote the report with colleagues from Stanford and New Orleans universities, said the diet involves eating normally one day and then cutting food intake the next day to between 20 and 50 per cent. Dr Johnson, who reports having lost 35lbs in the first 11 weeks of being on the diet, said: "We have observed improvement in a variety of disease conditions, starting within two weeks, including insulin resistance, asthma, seasonal allergies, rheumatoid arthritis, osteoarthritis, infectious disease, periodontal disease, and cardiac arrhythmias." For people who want to lose weight, according to the report, the diet has the psychological advantage of not subjecting them to permanent food deprivation. But the scientists said what they call "up-day, down-day" dieting also has health-promoting effects. http://www.eatqod.com/forum/viewtopic.php?p=178#178 Sun, 18 Jun 2006 07:19:30 GMT http://www.eatqod.com/forum/viewforum.php?f=12 Just started up this link today.

Noticed some tooth sensitivity after eating a lot of pickles, snacking on oranges, and started to look into this. Googled: "dental erosion acid food". Came up with some interesting links about how acidity in certain foods, esp. vinegar (salad dressing), oranges, tomatoes, and also soft drinks can cause tooth enamel to soften and be destroyed. Brushing makes things worse. See the QOD forum for more information. As healthy eating becomes more popular, and people start eating more fruits and certain vegetables, drinking veggie juice, etc., this may start becoming more of a problem. Just getting on the radar screen of public consciousness. http://www.eatqod.com/forum/viewtopic.php?p=142#142 Tue, 09 May 2006 13:22:12 GMT http://www.eatqod.com/forum/viewtopic.php?p=126#126 One oversight in the book was insufficient attention to magnesium. As laid out in Mildred Seelig's book, people eating a Western diet and drinking water that has little Mg, all tend to be Mg-deficient. Eating QOD can make this worse, because many veggies are not that high in Mg. So, in addition to calcium supplements, we should also take some Mg. See the link for recommendations. http://www.eatqod.com/forum/viewtopic.php?p=126#126 Wed, 19 Apr 2006 17:00:40 GMT http://www.eatqod.com/forum/viewtopic.php?p=124#124 From Macdonald and Webber: "Similarly, the first 2 d of total starvation are accompanied by increased resting energy expenditure (Mansell et al. 1990; Webber & Macdonald, 1994), which is likely to be due in part to the energy costs of gluconeogenesis, ketogenesis and fatty acid-triacylglyceroi recycling. The rates of gluconeogenesis and fatty acid-triacylglycerol recycling seen after 2-3 d of starvation could easily account for 5% of resting energy expenditure. As starvation proceeds there is a fall in resting energy expenditure, such that it is normally below initial values after 4 d of starvation (for review, see Elia, 1992)." http://www.eatqod.com/forum/viewtopic.php?p=124#124 Thu, 13 Apr 2006 23:39:53 GMT http://www.eatqod.com/forum/viewtopic.php?t=21 Scroll to the bottom of the link for new comments. Basically, there are other veggie juices out there, some that may have a better taste than V8 (it's a matter of personal preference), including juices made by President's Choice (distributed by Jewel Foods in the US), Knudsen tomato juice, and Kagome juices. See the Forum link for the weblinks to the companies that make these alternative juices. http://www.eatqod.com/forum/viewtopic.php?t=21 Sun, 09 Apr 2006 01:07:26 GMT
