NephroPal: Evolutionary Lifestyle - 0 views

    "Should you eat low carbohydrate and high saturated fat, or high carbohydrate and low fat, that is the question? This question is causing a tremendous back and forth in the medical and nutrition industry. It is unbelievable that the medical profession has not at least thoroughly tested the question. How is it that a magnificent experiment had been going on for 2.5 million years, the hunter gatherer Paleolithic life. This continued up to and until about about 10,000 years ago, with the advent of agriculture. After that time is when the diseases of the metabolic syndrome started to appear. This information is a matter of history. If a layman like me can recognize the validity of an experiment that continued for 2,5 million years, and produced healthy individuals, relative to the diseases of the metabolic syndrome, such as: obesity, diabetes type 2, cardiovascular disease and stroke, and some cancers to name just a few, then how is it, that the consensus opinion of the medical profession and nutritionists think that the hunter gatherer lifestyle of our ancient ancestors is unhealthful or dangerous? The consensus opinion says that low fat (trim all visible fat from the animal protein) and high carbohydrate food is the "healthy eating" choice for us. I personally know that instead of being healthy,it is unhealthy, because by following my doctors advice over the last 50 years many of the above mentioned diseases started to appear on my charts. "

Fructose may promote metabolic syndrome - 0 views

  •  
    "(NaturalNews) A research team from the University of Washington (UW) recently published a study in Physiology & Behavior revealing that moderate consumption of fructose- and high fructose corn syrup-sweetened beverages leads to significant alterations of lipid metabolization in the liver. Conducted on rats, the study also noted marked increases in both cholesterol and triglyceride levels in rats that fed on fructose-sweetened beverages.

    Fructose is a monosaccharide sugar that is found in various fruits. It is a simple sugar that is often promoted as being a healthy "fruit" sugar, however the reality is that fructose is just one component of the complex sugar composition that occurs naturally in fruit. Most granulated fructose available today, called crystalline fructose, is derived from fructose-enriched corn syrup.

    Similarly, high fructose corn syrup is a fructose-enriched form of highly-processed corn syrup that is commonly found in soda, ketchup, candy, dressings, and many other processed foods. The biggest concern about fructose is the fact that, unlike sucrose, it passes undigested through the small intestine where it enters the portal vein and heads directly to the liver. "

Could Omega-3s Boost Blood Fat Levels?: MedlinePlus - 0 views

  •  
    "THURSDAY, Dec. 17 (HealthDay News) -- In a surprise finding, Canadian researchers report that the immediate effect of the fish oil fatty acids that are good for the heart is a short-term increase in blood fats and the molecules that help them form clots.

    "We were surprised to find that the acute response has some potentially negative effects in comparison to what you might expect from chronic, long-term intake," said Lindsay E. Robinson, an associate professor of nutrition at the University of Guelph, and leader of the group reporting the finding in the January issue of the Journal of Nutrition.

    However, the study results shouldn't affect the current recommendation for eating more oily fish to get the omega-3 polyunsaturated acids that reduce the risk of blood clots that can cause heart attacks and stroke, Robinson said.

    "The recommendation to increase intake is very well-studied, and this doesn't change it," she said.

    And the effects were seen in a selected group of middle-aged men with metabolic syndrome, a combination of high blood pressure, obesity and elevated blood fat levels, Robinson noted.

    In the study, eight men had controlled intake of three regimens: high doses of omega-3 fatty acids, low doses of them and just plain water. Robinson and her colleagues measured several blood components involved in clotting, including fats and clotting factors such as plasminogen-activator inhibitor-1 (PAI-1) for the following eight hours.

    PAI-1 inhibits the destruction of blood clots, so high levels of it in the blood increase the risk of artery-blocking clots.

    The researchers found that both omega-3 fatty acid regimens increased blood fat and clotting factor activity. But the increase in clotting factor was greater for the higher doses of omega-3 fatty acids than for the lower intakes.

    Robinson said her group hopes to do further studies of the immediate effects of omega-3 fatty acid intake. "We need to look at the mechanisms, why blood lipid levels go up," she

    Acute Ingestion of Long-Chain (n-3) Polyunsaturated Fatty Acids Decreases Fibrinolysis in Men with Metabolic Syndrome.
    Montegaard C, Tulk HM, Lauritzen L, Tholstrup T, Robinson LE.
    J Nutr. 2009 Nov 4. [Epub ahead of print]
    PMID: 19889809
    doi:10.3945/jn.109.111427

    Individuals with metabolic syndrome (MetS) often have elevated plasma plasminogen activator inhibitor-1 (PAI-1) and tissue plasminogen activator (t-PA), contributing to an increased risk of cardiovascular disease. PAI-1 and t-PA may be affected by chronic (n-3) long-chain PUFA [(n-3)LCPUFA] supplementation; however, the acute impact of fat ingestion on these risk factors has not been established. Our objective was to investigate the acute effect of (n-3)LCPUFA on plasma PAI-1, t-PA, and platelet aggregation. We conducted a randomized crossover study in which men (n = 8, ≥45 y) with MetS consumed water or a high-saturated fat beverage (1 g fat/kg body weight) with either a high or low content of (n-3)LCPUFA. Blood samples were collected over 8 h to measure triacylglycerol (TAG), PAI-1, t-PA, and platelet aggregation. Both fat loads resulted in a significant increase in whole blood TAG concentration, plasma PAI-1 and t-PA concentrations, and PAI-1 activity, as well as a significant decrease in t-PA activity during the postprandial period. Interestingly, PAI-1 concentration and activity increased more following the high (n-3)LCPUFA compared with the low (n-3)LCPUFA beverage (P < 0.05). Furthermore, the high (n-3)LCPUFA beverage resulted in a lower t-PA activity (P < 0.05), whereas the effects of the 2 fat loads on the plasma t-PA concentration and platelet aggregation did not differ. Overall, acute intake of a high (n-3)LCPUFA beverage shifted the balance between plasma PAI-1 and t-PA, which might indicate a lower capacity for fibrinolysis

Low vitamin D linked with CVD risk factors in teens - theheart.org - 0 views

    "March 18, 2009 | Marlene Busko

    Palm Harbor, FL - In a large study of adolescents, low serum levels of 25-dihydroxyvitamin D (25[OH]D) strongly predicted prevalence of hypertension, hyperglycemia, and metabolic syndrome [1]. The findings were reported at the AHA 49th Annual Conference on Cardiovascular Disease Epidemiology and Prevention.

    Adolescents with vitamin-D levels in the lowest quartile were almost four times more likely to have metabolic syndrome than those with vitamin-D levels in the highest quartile. "I think that is quite alarming," lead author Dr Jared P Reis (Johns Hopkins Medical Institutions, Baltimore, MD) said in an AHA podcast issued to the media."

    CONCLUSIONS
    CLA and specifically the isolated isomers are interesting model fatty acids for studies of the effects of (structural differences of) unsaturated fatty acids in humans. Today, there is no clear indication for human use of CLA concentrates. The possible importance of the small reduction of body fat after supplementation with the commercially available CLA products, without evidence of an associated improvement in the metabolic profile, has to be weighed against the apparent reduction of HDL cholesterol and an increased lipid peroxidation. The possible health consequences of prolonged treatment periods are at present unknown. Human supplementation with high doses of the trans-10,cis-12 CLA isomer should be avoided while awaiting further information on possible effects and side effects. However, it cannot be excluded that future studies could point to clinical applications, eg, as a result of antitumorigenic properties or as a tool to prevent weight gain. This possibility certainly requires more research to increase the understanding of the mechanisms behind the effects of CLA and specific CLA isomers on a molecular level. More controlled studies in defined populations are needed, as are controlled studies for comparisons of the effects of different and well-defined (mixtures of) isomers and human studies of longer duration to secure long-term effects and safety.

Selfish Brain Theory - Wikipedia, the free encyclopedia - 0 views

  •  
    "The "Selfish Brain" theory describes the characteristic of the human brain to cover its own, comparably high energy requirements with the utmost of priorities when regulating energy fluxes in the organism. The brain behaves selfishly in this respect. The "Selfish brain" theory amongst other things provides a novel explanation for the origin of obesity, the severe and pathological form of overweight. The Luebeck obesity and diabetes specialist Achim Peters developed the fundamentals of this theory between 1998 and 2004. The interdisciplinary "Selfish Brain: brain glucose and metabolic syndrome" research group headed by Peters and supported by the German Research Foundation (DFG) at the University of Luebeck has in the meantime been able to reinforce the basics of the theory through experimental research. Scientists the world over now consider this work as pioneering for the study of the causes of pathological eating disorders and the development of innovative therapies."

    Hypovitaminosis D is associated with insulin resistance and beta cell dysfunction.
    Chiu KC, Chu A, Go VL, Saad MF.
    Am J Clin Nutr. 2004 May;79(5):820-5.
    PMID: 15113720

    Conclusions: The data show a positive correlation of 25(OH)D concentration with insulin sensitivity and a negative effect of hypovitaminosis D on ß cell function. Subjects with hypovitaminosis D are at higher risk of insulin resistance and the metabolic syndrome. Further studies are required to explore the underlying mechanisms.

    Parathyroid hormone, but not vitamin D, is associated with the metabolic syndrome in morbidly obese women and men: a cross-sectional study.
    Hjelmesaeth J, Hofsø D, Aasheim ET, Jenssen T, Moan J, Hager H, Røislien J, Bollerslev J.
    Cardiovasc Diabetol. 2009 Feb 3;8:7.
    PMID: 19187564
    doi:10.1186/1475-2840-8-7

    CONCLUSION: The PTH level, but not the vitamin D level, is an independent predictor of MS in treatment seeking morbidly obese Caucasian women and men. Randomized controlled clinical trials, including different therapeutic strategies to lower PTH, e.g. calcium/vitamin D supplementation and weight reduction, are necessary to explore any cause-and-effect relationship.

    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.

Low Vitamin D Hurts Teenagers' Hearts - 0 views

  •  
    March 11, 2009 -- Low vitamin D levels greatly increase a teenager's risk of diabetes and heart disease, Johns Hopkins researchers find.

    It is becoming clear that adults who get too little vitamin D are at higher risk for diabetes and heart disease. Now, it appears vitamin D levels also affect these risks earlier in life, say Johns Hopkins researchers Jared P. Reis, PhD, and colleagues.
