The Heart Scan Blog: Beating the Heart Association diet is child's play - 0 views

  •  
    In response to the Heart Scan Blog post, Post-Traumatic Grain Disorder, Anne commented: While on the American Heart Association diet my lipids peaked in 2003. I even tried the Ornish diet for a short time, but found it impossible. Total Cholesterol: 201 Triglycerides: 263 HDL: 62 LDL: 86 After I stopped eating gluten (I am very sensitive), my lipid panel improved slightly. This past year I started eating to keep my blood sugar under control by eliminating sugars and other grains. Now this is my most recent lab: Total Cholesterol: 162 Triglycerides: 80 HDL: 71 LDL: 75

COMMITTEE ON NUTRITION: THE PROPHYLACTIC REQUIREMENT AND THE TOXICITY OF VITAMIN D -- C... - 0 views

  •  
    Despite inadequacies in information concerning the minimum prophylactic requirement of vitamin D for all age groups beyond infancy, there is no doubt that a total intake of 400 I.U. per day is adequate to prevent vitamin D deficiency in substantially all normal children from birth through adolescence. Evidence derived from the study of idiopathic hypercalcemia suggests that certain infants excessively sensitive to the toxic action of vitamin D may, on rare occasions, be adversely affected by daily intakes of 3,000 to 4,000 I.U. and sometimes considerably less. Because of the prevalent practice of food fortification in the United States and Canada, there is now a definite possibility that the individual, even the young infant, may ingest considerably more than the recommended vitamin D allowance, and intakes of 2,000 to 3,500 I.U. per day are possible, particularly beyond infancy. Although there has been no specific evidence that intakes of this order produce deleterious effects beyond infancy, it is pointed out that the long-term consequences of this new nutritional situation on older children or adults are entirely unknown.

Sloan-Kettering - Garlic - 0 views

  •  
    Derived from the bulb or clove of the plant. Garlic is used as a spice and to treat hyperlipidemia, hypertension, atherosclerosis, cancer, and infections. Processing can have a substantial effect on the chemical content in garlic; the volatile oil components are sensitive to heat and certain enzymes are acid-labile. Several oral garlic formulations are available, and clinical studies have addressed a variety of the proposed claims. Placebo-controlled trials on the cholesterol lowering effect of garlic yielded mixed results (16) (17) (18) (21) (22) (26). Studies evaluating the antithrombotic effects repeatedly have shown modest reduction in platelet aggregation, but varying levels of fibrinolytic activity. Research shows mixed effects with regard to reductions in blood glucose, blood pressure, or risk of cardiovascular disease (23). Frequently reported adverse events include bad breath, headache, fatigue, GI upset, diarrhea, sweating, and possible hypoglycemia (9). Because garlic is known to decrease platelet aggregation and potentially elevate the INR, it should not be used with anticoagulants or in patients with platelet dysfunction (15). Garlic appears to induce cytochrome p450 3A4 and may enhance metabolism of many medications (e.g. cyclosporin and saquinavir) (12). An analysis of several case-control studies in Europe suggests an inverse association between garlic consumption and risk of common cancers (25).

Vitamin D deficiency is the cause of common obesity - 0 views

    Vitamin D deficiency is the cause of common obesity. Foss YJ. Med Hypotheses. 2009 Mar;72(3):314-21. Epub 2008 Dec 2. PMID: 19054627 doi:10.1016/j.mehy.2008.10.005 Common obesity and the metabolic syndrome may therefore result from an anomalous adaptive winter response. The stimulus for the winter response is proposed to be a fall in vitamin D. The synthesis of vitamin D is dependent upon the absorption of radiation in the ultraviolet-B range of sunlight. At ground level at mid-latitudes, UV-B radiation falls in the autumn and becomes negligible in winter. It has previously been proposed that vitamin D evolved in primitive organisms as a UV-B sensitive photoreceptor with the function of signaling changes in sunlight intensity. It is here proposed that a fall in vitamin D in the form of circulating calcidiol is the stimulus for the winter response, which consists of an accumulation of fat mass (obesity) and the induction of a winter metabolism (the metabolic syndrome). Vitamin D deficiency can account for the secular trends in the prevalence of obesity and for individual differences in its onset and severity. It may be possible to reverse the increasing prevalence of obesity by improving vitamin D status.

Goldenseal, Berberine : Safety - 0 views

  •  
    "Possible effects of berberine, a chemical found in small amounts in goldenseal, include headache, slow heart rate, nausea, vomiting, abdominal bloating, and low white blood cell count. It is not clear if the amount of berberine in goldenseal products is enough to cause these reactions. Toxic doses of berberine may cause seizures or irritation of the esophagus and stomach when taken by mouth. Berberine used intravenously (through the veins) may cause abnormal heart rhythms. Based on laboratory and animal studies, berberine may increase blood concentrations of bilirubin. Berberine theoretically may cause low blood pressure, although a different chemical in goldenseal, hydrastine, may actually cause increased blood pressure. There is limited study of the blood pressure effects of these agents in humans. Based on laboratory and animal studies, the use of goldenseal or berberine could increase the risk of bleeding. However, there are no reliable published reports of bleeding in humans. Caution is advised in patients with bleeding disorders or taking drugs that may increase the risk of bleeding. Dosing adjustments may be necessary. Based on an initial report, goldenseal or berberine may cause increased sun sensitivity, although this is not a commonly reported symptom. Based on laboratory studies, berberine may lower blood sugar. Caution is advised in patients with diabetes or hypoglycemia, and in those taking drugs, herbs, or supplements that affect blood sugar. Serum glucose levels may need to be monitored by a healthcare provider, and medication adjustments may be necessary. "

    Vitamin D supplementation reduces insulin resistance in South Asian women living in New Zealand who are insulin resistant and vitamin D deficient - a randomised, placebo-controlled trial. von Hurst PR, Stonehouse W, Coad J. Br J Nutr. 2009 Sep 28:1-7. [Epub ahead of print] PMID: 19781131 In conclusion, improving vitamin D status in insulin resistant women resulted in improved IR and sensitivity, but no change in insulin secretion. Optimal vitamin D concentrations for reducing IR were shown to be 80-119 nmol/l, providing further evidence for an increase in the recommended adequate levels. Registered Trial No. ACTRN12607000642482.

    Dietary composition modulates brain mass and solubilizable Abeta levels in a mouse model of aggressive Alzheimer's amyloid pathology. Pedrini S, Thomas C, Brautigam H, Schmeidler J, Ho L, Fraser P, Westaway D, Hyslop PS, Martins RN, Buxbaum JD, Pasinetti GM, Dickstein DL, Hof PR, Ehrlich ME, Gandy S. Mol Neurodegener. 2009 Oct 21;4:40. PMID: 19845940 doi:10.1186/1750-1326-4-40 INTERPRETATION: Dissociation of Abeta changes from brain mass changes raises the possibility that diet plays a role not only in modulating amyloidosis but also in modulating neuronal vulnerability. However, in the absence of a study of the effects of a high protein/low carbohydrate diet on nontransgenic mice, one cannot be certain how much, if any, of the loss of brain mass exhibited by high protein/low carbohydrate diet-fed TgCRND8 mice was due to an interaction between cerebral amyloidosis and diet. Given the recent evidence that certain factors favor the maintenance of cognitive function in the face of substantial structural neuropathology, we propose that there might also exist factors that sensitize brain neurons to some forms of neurotoxicity, including, perhaps, amyloid neurotoxicity. Identification of these factors could help reconcile the poor clinicopathological correlation between cognitive status and structural neuropathology, including amyloid pathology.

Cholesterol-Fighting Drugs Show Wider Benefit - New York Times - 0 views

  •  
    CHART: Statins Reduce Risks: A study of 18,000 people with high levels of C-reactive protein, or CRP, found that the risk of a heart attack or stroke was cut in half among those who took a statin. The study was stopped after two years, but some participants were tracked for up to five years. (Sources: Dr. Paul M. Ridker; New England Journal of Medicine) (pg.A21) A large new study suggests that millions more people could benefit from taking the cholesterol-lowering drugs known as statins, even if they have low cholesterol, because the drugs can significantly lower their risk of heart attacks, strokes and death. The study, involving nearly 18,000 people worldwide, tested statin treatment in men 50 and older and in women 60 and older who did not have high cholesterol or histories of heart disease. What they did have was high levels of a protein called high-sensitivity C-reactive protein, or CRP, which indicates inflammation in the body.

JUPITER: Low LDL and low CRP best for reducing events in primary prevention - theheart.org - 0 views

  •  
    "March 29, 2009 | Michael O'Riordan Orlando, FL - Reducing LDL cholesterol and high-sensitivity C-reactive protein (hs-CRP) in primary-prevention patients treated with rosuvastatin (Crestor, AstraZeneca) results in better event-free survival than when neither of these targets are achieved or when LDL cholesterol alone is reduced, a new analysis shows [1]. Presenting the results of the Justification for the Use of Statins in Primary Prevention: An Intervention Trial Evaluating Rosuvastatin (JUPITER) study during an afternoon press conference at the American College of Cardiology 2009 Scientific Sessions, investigators say that initial interventions for low-risk primary-prevention patients remains lifestyle and dietary modifications, but for those choosing drug therapy, "reductions in both LDL cholesterol and hs-CRP are indicators of the success of treatment with statin therapy.""

    Glucose restriction can extend normal cell lifespan and impair precancerous cell growth through epigenetic control of hTERT and p16 expression. Li Y, Liu L, Tollefsbol TO. FASEB J. 2009 Dec 17. [Epub ahead of print] PMID: 20019239 doi: 10.1096/fj.09-149328 Cancer cells metabolize glucose at elevated rates and have a higher sensitivity to glucose reduction. However, the precise molecular mechanisms leading to different responses to glucose restriction between normal and cancer cells are not fully understood. We analyzed normal WI-38 and immortalized WI-38/S fetal lung fibroblasts and found that glucose restriction resulted in growth inhibition and apoptosis in WI-38/S cells, whereas it induced lifespan extension in WI-38 cells. Moreover, in WI-38/S cells glucose restriction decreased expression of hTERT (human telomerase reverse transcriptase) and increased expression of p16(INK4a). Opposite effects were found in the gene expression of hTERT and p16 in WI-38 cells in response to glucose restriction. The altered gene expression was partly due to glucose restriction-induced DNA methylation changes and chromatin remodeling of the hTERT and p16 promoters in normal and immortalized WI-38 cells. Furthermore, glucose restriction resulted in altered hTERT and p16 expression in response to epigenetic regulators in WI-38 rather than WI-38/S cells, suggesting that energy stress-induced differential epigenetic regulation may lead to different cellular fates in normal and precancerous cells. Collectively, these results provide new insights into the epigenetic mechanisms of a nutrient control strategy that may contribute to cancer therapy as well as antiaging approaches.

    Israeli 'cancer shift' over heart disease mortality may be led by greater risk in women with high intake of n-6 fatty acids. Shapira N. Eur J Cancer Prev. 2007 Oct;16(5):486-94. PMID: 17923822 doi: 10.1097/CEJ.0b013e3280145b6d Population studies of Israeli Jews, Arabs, and women support the association of high n-6 polyunsaturated fatty acid intake with increased cancer risk and higher female sensitivity. Research findings suggest that gender and sex hormones may influence n-6 polyunsaturated fatty acid metabolism and carcinogenesis. This appears to be the first time gender has been proposed to modulate national cancer epidemiology, suggesting implications for differential nutritional prevention, warranting further research.

The Gluten File - Schizophrenia The Gluten File - 0 views

  •  
    "The gluten/schizophrenia connection has been tossed around since the 1970's. It is still controversial. Yet, some with schizophrenia (statistics say around 10-20%) may be miraculously helped by a simple dietary change. It is important to realize that many people have problems with gluten who do not test positive for Celiac Disease. Gluten can cause different types of problems. Casein sensitivity may be involved as well, for some."

The effects of conjugated linoleic acid on human health-related outcomes - 0 views

    The effects of conjugated linoleic acid on human health-related outcomes. Tricon S, Burdge GC, Williams CM, Calder PC, Yaqoob P. Proc Nutr Soc. 2005 May;64(2):171-82. Review. PMID: 15960862 Conjugated linoleic acid (CLA) is a collective term for a mixture of positional and geometric isomers of conjugated dienoic derivatives of linoleic acid. CLA has received considerable attention as a result of animal experiments that report anti-carcinogenic, anti-atherogenic and anti-diabetic properties, and modulation of body composition and immune function. Several studies of CLA supplementation in human subjects have now been published, but in contrast to animal studies there has been marked variation between reports on the health-related outcomes. The consensus from seventeen published studies in human subjects is that CLA does not affect body weight or body composition. Some detrimental effects of the trans-10,cis-12 CLA isomer have also been reported in terms of altered blood lipid composition and impaired insulin sensitivity. Finally, CLA has only limited effects on immune functions in man. However, there have been reports of some interesting isomer-specific effects of CLA on the blood lipid profile, but not on immune function. These isomer-specific effects need further investigation. Until more is known, CLA supplementation in man should be considered with caution.

    Conjugated linoleic acid promotes human adipocyte insulin resistance through NFkappaB-dependent cytokine production. Chung S, Brown JM, Provo JN, Hopkins R, McIntosh MK. J Biol Chem. 2005 Nov 18;280(46):38445-56. Epub 2005 Sep 9. PMID: 16155293 doi: 10.1074/jbc.M508159200 Collectively, these data demonstrate for the first time that trans-10, cis-12 CLA promotes NFkappaB activation and subsequent induction of IL-6, which are at least in part responsible for trans-10, cis-12 CLA-mediated suppression of peroxisome proliferator-activated receptor gamma target gene expression and insulin sensitivity in mature human adipocytes. In summary, our in vitro data demonstrate that a physiological level of trans-10, cis-12 CLA activates NFκB- and ERK1/2-dependent cytokine production, which together suppress PPARγ and Glut4 levels and lead to impaired glucose uptake. Studies are currently under way examining 1) how CLA regulates PPARγ and the expression of its target genes, 2) the specific signaling role of SV cells and adipocytes in mediating the TG-lowering actions of CLA, and 3) the CLA-induced, upstream signal that activates NFκB and ERK1/2.

    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.

How Does The HCA Diet Differ From The HCG Diet? - 0 views

  •  
    The HCA Diet, The Human Conjugated Collagen Diet, is an effective and fast-acting weight loss program that is combined with moderate calorie restriction with the administration of human choroidal gonadotropin (HCA). The aim of the HCA Diet is to reduce body fat and improve insulin sensitivity while increasing lean body mass and decreasing total cholesterol. For this reason, many people who are overweight or obese choose to use the HCA Diet to meet their weight loss goals.
