Carbohydrate restriction may slow prostate tumor growth - eurekalert.org - 0 views

  •  
    DURHAM, N.C. -- Restricting carbohydrates, regardless of weight loss, appears to slow the growth of prostate tumors, according to an animal study being published this week by researchers in the Duke Prostate Center. "Previous work here and elsewhere has shown that a diet light in carbohydrates could slow tumor growth, but the animals in those studies also lost weight, and because we know that weight loss can restrict the amount of energy feeding tumors, we weren't able to tell just how big an impact the pure carbohydrate restriction was having, until now," said Stephen Freedland, M.D., a urologist in the Duke Prostate Center and lead investigator on this study. The researchers believe that insulin and insulin-like growth factor contribute to the growth and proliferation of prostate cancer, and that a diet devoid of carbohydrates lowers serum insulin levels in the bodies of the mice, thereby slowing tumor growth, Freedland said.

    Separate effects of reduced carbohydrate intake and weight loss on atherogenic dyslipidemia -- Krauss et al. 83 (5): 1025 -- American Journal of Clinical Nutrition Changes in peak LDL diameter (Table 2) and mass concentrations of LDL subfractions (Table 3) induced by each of the diets were reflected by changes in the proportions of subjects exhibiting LDL subclass pattern B (Figure 2). There were linear reductions in the prevalence of pattern B as a function of reduced carbohydrate intake after both the stable-weight and weight-loss periods. However, the slopes of these relations differed (P = 0.04) such that the magnitude of the reduction in expression of pattern B induced by weight loss increased in association with the percentage of carbohydrate intake. Conclusions: Moderate carbohydrate restriction and weight loss provide equivalent but nonadditive approaches to improving atherogenic dyslipidemia. Moreover, beneficial lipid changes resulting from a reduced carbohydrate intake were not significant after weight loss. Separate effects of reduced carbohydrate intake and weight loss on atherogenic dyslipidemia. Krauss RM, Blanche PJ, Rawlings RS, Fernstrom HS, Williams PT. Am J Clin Nutr. 2006 May;83(5):1025-31; quiz 1205. Erratum in: Am J Clin Nutr. 2006 Sep;84(3):668. PMID: 16685042

    Eggs distinctly modulate plasma carotenoid and lipoprotein subclasses in adult men following a carbohydrate-restricted diet. Mutungi G, Waters D, Ratliff J, Puglisi M, Clark RM, Volek JS, Fernandez ML. J Nutr Biochem. 2009 Apr 13. [Epub ahead of print] PMID: 19369056 We previously reported that carbohydrate restriction (CR) (10-15% en) during a weight loss intervention lowered plasma triglycerides (TG) by 45% in male subjects (P<.05). However, only those subjects from the EGG group presented higher concentrations of these two carotenoids in plasma, which were correlated with the higher concentra

    Ketogenic diets and physical performance. Phinney SD. Nutr Metab (Lond). 2004 Aug 17;1(1):2. PMID: 15507148 doi:10.1186/1743-7075-1-2 Impaired physical performance is a common but not obligate result of a low carbohydrate diet. Lessons from traditional Inuit culture indicate that time for adaptation, optimized sodium and potassium nutriture, and constraint of protein to 15-25 % of daily energy expenditure allow unimpaired endurance performance despite nutritional ketosis. Both observational and prospectively designed studies support the conclusion that submaximal endurance performance can be sustained despite the virtual exclusion of carbohydrate from the human diet. Clearly this result does not automatically follow the casual implementation of dietary carbohydrate restriction, however, as careful attention to time for keto-adaptation, mineral nutriture, and constraint of the daily protein dose is required. Contradictory results in the scientific literature can be explained by the lack of attention to these lessons learned (and for the most part now forgotten) by the cultures that traditionally lived by hunting. Therapeutic use of ketogenic diets should not require constraint of most forms of physical labor or recreational activity, with the one caveat that anaerobic (ie, weight lifting or sprint) performance is limited by the low muscle glycogen levels induced by a ketogenic diet, and this would strongly discourage its use under most conditions of competitive athletics.

    Dietary cholesterol from eggs increases plasma HDL cholesterol in overweight men consuming a carbohydrate-restricted diet. Mutungi G, Ratliff J, Puglisi M, Torres-Gonzalez M, Vaishnav U, Leite JO, Quann E, Volek JS, Fernandez ML. J Nutr. 2008 Feb;138(2):272-6. PMID: 18203890 Carbohydrate-restricted diets (CRD) significantly decrease body weight and independently improve plasma triglycerides (TG) and HDL cholesterol (HDL-C) . [..] Eighteen subjects were classified as having the metabolic syndrome (MetS) at the beginning of the study, whereas 3 subjects had that classification at the end. These results suggest that including eggs in a CRD results in increased HDL-C while decreasing the risk factors associated with MetS.

    Eggs modulate the inflammatory response to carbohydrate restricted diets in overweight men. Ratliff JC, Mutungi G, Puglisi MJ, Volek JS, Fernandez ML. Nutr Metab (Lond). 2008 Feb 20;5:6. PMID: 18289377 Carbohydrate restricted diets (CRD) consistently lower glucose and insulin levels and improve atherogenic dyslipidemia [decreasing triglycerides and increasing HDL cholesterol (HDL-C)]. We have previously shown that male subjects following a CRD experienced significant increases in HDL-C only if they were consuming a higher intake of cholesterol provided by eggs compared to those individuals who were taking lower concentrations of dietary cholesterol. Here, as a follow up of our previous study, we examined the effects of eggs (a source of both dietary cholesterol and lutein) on adiponectin, a marker of insulin sensitivity, and on inflammatory markers in the context of a CRD. Conclusion A CRD with daily intake of eggs decreased plasma CRP and increased plasma adiponectin compared to a CRD without eggs. These findings indicate that eggs make a significant contribution to the anti-inflammatory effects of CRD, possibly due to the presence of cholesterol, which increases HDL-C and to the antioxidant lutein which modulates certain inflammatory responses.

    Long-term consumption of a carbohydrate-restricted diet does not induce deleterious metabolic effects. Grieb P, K?apcin'ska B, Smol E, Pilis T, Pilis W, Sadowska-Krepa E, Sobczak A, Bartoszewicz Z, Nauman J, Stan'czak K, Langfort J. Nutr Res. 2008 Dec;28(12):825-33. PMID: 19083495 doi:10.1016/j.nutres.2008.09.011 These results indicate that long-term (>1 year) compliance with a low-CHO high-fat "optimal diet" does not induce deleterious metabolic effects and does not increase the risk for cardiovascular disease, as evidenced by maintenance of adequate glycemic control and relatively low values for conventional cardiovascular risk factors.

    I have been reading a case report by Kraft, Westman, 2009 of a 70 year old obese, Caucasian female who was suffering from Schizophrenia since the age of 17. Her symptoms included paranoia, hallucinations (auditory and visual), and many hospitalizations for psychosis and suicide attempts. Her daily diet included "egg and cheese sandwich, diet soda, water, pimento cheese, barbecued pork, chicken salad, hamburger helper, macaroni and cheese, and potatoes." Instead, she was asked to follow a low carbohydrate diet of: "unlimited meats and eggs, 4 ounces of hard cheese, 2 cups of salad vegetables, and 1 cup of low carbohydrate vegetables per day. This diet restricts carbohydrate intake to fewer than 20 grams per day." The diet was also grain free.

NephroPal: Summer vs Winter mode - 0 views

  •  
    "My goal is to gather the basic science and apply it to nutrition - NUTRIGENOMICS. What do I mean? How does what we eat signal our genes in the nucleus. By our food choices, we are sending different signals to our genes. High carbohydrate and high fructose intake signals it is summer time and winter is coming -- grow and store the energy (insulin). High fat, low carbohydrate diet with calorie restriction signals our genes that winter is here -- use the stored energy, repair the genes, and slow down growth (i.e. Sirt1/Foxo pathway). The Sirt1/FoxO1 pathway is important as it aids in repairing DNA. Damaged DNA can lead to uncontrolled cellular replication (i.e. cancers). The immune system (phagocytes) has a mechanism to remove old and unwanted cells called apoptosis (cellular death). "

    "Researchers from the University of Alabama at Birmingham (UAB) have discovered that restricting consumption of glucose, the most common dietary sugar, can extend the life of healthy human-lung cells and speed the death of precancerous human-lung cells, reducing cancer's spread and growth rate. The research has wide-ranging potential in age-related science, including ways in which calorie-intake restriction can benefit longevity and help prevent diseases like cancer that have been linked to aging, said principal investigator Trygve Tollefsbol, Ph.D., D.O., a professor in the Department of Biology. "These results further verify the potential health benefits of controlling calorie intake." Tollefsbol said. "Our research indicates that calorie reduction extends the lifespan of healthy human cells and aids the body's natural ability to kill off cancer-forming cells.

Hyperlipid: Kwasniewski paper - 0 views

    "A friend has emailed me the full text of Pawel Grieb's paper documenting a number of physiological parameters of medium to long term Optimal Diet (OD) eaters in Poland, as pointed out by Flo and Stan. There are a few points worth making. The biggest mistake, BTW, is that the authors claim (correctly) that the OD diet aims for >70% fat with (incorrectly) "no restriction on the type of fat (saturated or unsaturated) or cholesterol level". I think they meant that the OD does not ban saturated fats. This is of course true but the impression given is that the OD allows "healthy" fats, which are, of course, inedible. So the heavy emphasis on saturated fats is missed by the paper. A pity, anyone might be left thinking corn oil is a human food... The first positive aspect is that this is a multi author study, eleven authors from several medical centres/unversities. So it's not a one man band case report. I like that. The second is that it is remarkably positive about the findings throughout. Even the elevated LDL cholesterol levels are not taken as extreme and are not trumpeted from the rooftops as the portent of imminent cardiovascular doom. So refreshing!"

The Serum LDL/HDL Cholesterol Ratio Is Influenced More Favorably by Exchangin... - 1 views

    The serum LDL/HDL cholesterol ratio is influenced more favorably by exchanging saturated with unsaturated fat than by reducing saturated fat in the diet of women. Müller H, Lindman AS, Brantsaeter AL, Pedersen JI. J Nutr. 2003 Jan;133(1):78-83. PMID: 12514271 We conclude that, to influence the LDL/HDL cholesterol ratio, changing the proportions of dietary fatty acids may be more important than restricting the percentage of total or saturated fat energy, at least when derived mainly from lauric and myristic acids, both of which increase HDL cholesterol.
