Prospective Study of Glycemic Load, Glycemic Index, and Carbohydrate Intake in Relation to Risk of Biliary Tract Cancer.

Abstract Title: Prospective Study of Glycemic Load, Glycemic Index, and Carbohydrate Intake in Relation to Risk of Biliary Tract Cancer. Abstract Source: Am J Gastroenterol. 2016 Jun ;111(6):891-6. Epub 2016 Mar 29. PMID: 27021191 Abstract Author(s): Susanna C Larsson, Edward L Giovannucci, Alicja Wolk Article Affiliation: Susanna C Larsson Abstract: OBJECTIVES: Diets that induce a high glycemic response might increase the risk of biliary tract cancer (BTC). We evaluated the hypothesis that diets with high glycemic load (GL) and high glycemic index (GI), which are measures of the glycemic effect of foods, are associated with an increased incidence of BTC. METHODS: We used data from a population-based prospective study of 76,014 Swedish adults (age 45-83 years; 57% men) who were free of cancer and had completed a food-frequency questionnaire in the autumn of 1997. Incident cancer cases were ascertained by linkage with the Swedish Cancer Registry. Data were analyzed using Cox proportional hazards regression models. RESULTS: During a mean follow-up of 13.3 years (1,010,777 person-years), we identified 140 extrahepatic BTC cases (including 77 gallbladder cancers) and 23 intrahepatic BTC cases. A high dietary GL was associated with an increased risk of BTC. The multivariable relative risks for the highest versus lowest quartile of dietary GL were 1.63 (95% confidence interval (95% CI), 1.01-2.63) for extrahepatic BTC, 2.14 (95% CI, 1.06-4.33) for gallbladder cancer, and 3.46 (95% CI, 1.22-9.84) for intrahepatic BTC. Dietary GI was statistically significantly positively associated with risk of extrahepatic BTC and gallbladder cancer. We observed no statistically significant association between carbohydrate intake and BTC risk, although all associations were positive. CONCLUSION: Although these data do not prove a causal relationship, they are consistent with the hypothesis that high-GL and high-GI diets are associated with an increased risk of BTC.

Metabolic Correction as a tool to improve diabetes type 2 management.

Abstract Title: Metabolic Correction as a tool to improve diabetes type 2 management. Abstract Source: Bol Asoc Med P R. 2015 Apr-Jun;107(2):54-9. PMID: 26434085 Abstract Author(s): Jorge R Miranda-Massari, Michael J Gonzalez, Alvarez-Soto Fernando, Carlos Cidre, Iván M Paz, Jorge Charvel, Viridiana Martínez, Jorge Duconge, Aileen Aponte, Carlos M Ricart Article Affiliation: Jorge R Miranda-Massari Abstract: Diabetes Mellitus type 2 (DM2) is a metabolic disease that develops by a decrease in sensitivity of insulin receptors as an effect of the disruption certain metabolic functions in the processing of glucose. DM2 patients have, uncontrolled glucose levels, and commonly have problems with obesity and cardiovascular disease. Patients are treated with standard diet, insulin, diabetic oral agents and antihypertensive drugs, but this approach does not completely stops tissue deterioration since it does not address the metabolic root of the disease. Metabolic correction is proposed as a suitable adjunct treatment to improve clinical outcomes. Metabolic correction is based on diet modification, proper hydration and scientific supplementation directed to improve cellular biochemistry and metabolic efficiency. In addition, other possible benefits may include reduction in medication use, disease complications and medical costs. To test the results of a metabolic correction program, 25 patients with DM2 participated in an education program about adequate food consumption that promoted control of blood glucose levels. Anthropometric measurements and blood tests were performed during a 13 week program based on a low carbohydrate diet, proper hydration and magnesium supplementation. The metabolic correction program implemented by a proprietary educational system resulted in significant reductions in glucose, triglycerides, cholesterol, weight and waist circumference. Improvements in these values could represent an important reduction of coronary heart disease risk factors as well as other chronic degenerative diseases. In addition there was medication dosage reduction in one or more medications in 21 of the 25 participating patients, which suggest that the program has the potential to improve health outcomes and reduce health care costs.

Synergic chemoprevention with dietary carbohydrate restriction and supplementation of AMPK-activating phytochemicals: the role of SIRT1. 📎

Abstract Title: Synergic chemoprevention with dietary carbohydrate restriction and supplementation of AMPK-activating phytochemicals: the role of SIRT1. Abstract Source: Eur J Cancer Prev. 2015 Mar 19. Epub 2015 Mar 19. PMID: 25747515 Abstract Author(s): Jong Doo Lee, Min-Ah Choi, Simon Weonsang Ro, Woo Ick Yang, Arthur E H Cho, Hye-Lim Ju, Sinhwa Baek, Sook In Chung, Won Jun Kang, Mijin Yun, Jeon Han Park Article Affiliation: Jong Doo Lee Abstract: Calorie restriction or a low-carbohydrate diet (LCD) can increase life span in normal cells while inhibiting carcinogenesis. Various phytochemicals also have calorie restriction-mimetic anticancer properties. We investigated whether an isocaloric carbohydrate-restriction diet and AMP-activated protein kinase (AMPK)-activating phytochemicals induce synergic tumor suppression. We used a mixture of AMPK-activating phytochemical extracts including curcumin, quercetin, catechins, and resveratrol. Survival analysis was carried out in a B16F10 melanoma model fed a control diet (62.14% kcal carbohydrate, 24.65% kcal protein and 13.2% kcal fat), a control diet with multiple phytochemicals (MP), LCD (16.5, 55.2, and 28.3% kcal, respectively), LCD with multiple phytochemicals (LCDmp), a moderate-carbohydrate diet (MCD, 31.9, 62.4, and 5.7% kcal, respectively), or MCD withphytochemicals (MCDmp). Compared with the control group, MP, LCD, or MCD intervention did not produce survival benefit, but LCDmp (22.80±1.58 vs. 28.00±1.64 days, P=0.040) and MCDmp (23.80±1.08 vs. 30.13±2.29 days, P=0.008) increased the median survival time significantly. Suppression of the IGF-1R/PI3K/Akt/mTOR signaling, activation of the AMPK/SIRT1/LKB1pathway, and NF-κB suppression were the critical tumor-suppression mechanisms. In addition, SIRT1 suppressed proliferation of the B16F10 and A375SM cells under a low-glucose condition. Alterations in histone methylation within Pten and FoxO3a were observed after the MCDmp intervention. In the transgenic liver cancer model developed by hydrodynamic transfection of the HrasG12V and shp53, MCDmp and LCDmp interventions induced significant cancer-prevention effects. Microarray analysis showed that PPARα increased with decreased IL-6 and NF-κB within the hepatocytes after an MCDmp intervention. In conclusion, an isocaloric carbohydrate-restriction diet and natural AMPK-activating agents induce synergistic anticancer effects. SIRT1 acts as a tumor suppressor under a low-glucose condition.This is an open-access article distributedunder the terms of the Creative Commons Attribution-NonCommercial-NoDerivatives 3.0 License, where it is permissible to download and share the work provided it is properly cited.

Effects of a moderate low-carbohydrate diet on preferential abdominal fat loss and cardiovascular risk factors in patients with type 2 diabetes. 📎

Abstract Title: Effects of a moderate low-carbohydrate diet on preferential abdominal fat loss and cardiovascular risk factors in patients with type 2 diabetes. Abstract Source: Diabetes Metab Syndr Obes. 2011 ;4:167-74. Epub 2011 Apr 29. PMID: 21779148 Abstract Author(s): Tae Sasakabe, Hajime Haimoto, Hiroyuki Umegaki, Kenji Wakai Article Affiliation: Department of Clinical Nutrition, Haimoto Clinic, Yayoi, Kasugai, Aichi, Japan; Abstract: BACKGROUND: Reports have shown that visceral adipose tissue (VAT) is more closely linked to cardiovascular risk factors (CRFs) than subcutaneous adipose tissue (SAT). We aimed to elucidate preferential abdominal fat loss and the correlations between abdominal fat reductions and changes in CRFs achieved with a moderate low-carbohydrate diet (LCD) in patients with type 2 diabetes (T2DM). PATIENTS AND METHODS: Fifty-two outpatients (28 men and 24 women, mean age± SD: 60.0 ± 10.5 years) with hemoglobin A(1c) (HbA(lc)) levels ≥ 6.5% were on an LCD for 6 months. Over a 6-month period, we measured their abdominal fat distribution (using CT) and assessed CRFs, including body mass index (BMI), HbA(1c), fasting blood glucose (FBG), serum insulin, high-densitylipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and triglyceride levels. RESULTS: The patients showed good compliance with the LCD (1812± 375 kcal/day, % carbohydrate:fat:protein = 35:40:19 for men; 1706 ± 323 kcal/day, % carbohydrate:fat:protein = 41:36:21 for women). Significant decreases (P = 0.05) in BMI and HbA(1c) levels were observed, along with an increase in HDL-C (P = 0.021) in men and a decrease in LDL-C (P = 0.001) inwomen. VAT (-21.6 cm(2), P<0.001 in men; -19.6 cm(2), P<0.001 in women) and SAT (-13.5 cm(2), P = 0.004 in men; -19.1 cm(2), P = 0.003 in women) significantly decreased. The loss of VAT (%ΔVAT) was greater than that of SAT (%ΔSAT) in women (P = 0.022). A similar but not significant predominance of VAT loss was detected in men (P = 0.111). In women, the %ΔSAT significantly correlated with changes in FBG (ΔFBG) (r = 0.417) and HDL-C (ΔHDL) (r = -0.720), as was %ΔVAT with changesin triglyceride (ΔTG) (r = 0.591). CONCLUSION: Six months of a moderate LCD resulted in preferential VAT loss only in women, with significant correlations between %ΔSAT and both ΔHDL and ΔFBG, as well as between %ΔVAT and ΔTG. Our results suggest that an LCD has the potential to reduce abdominal fat in patients with T2DM and deterioration of serum lipid profiles. Article Published Date : Jan 01, 2011

Low-carbohydrate diet disrupts the association between insulin resistance and weight gain.

Abstract Title: Low-carbohydrate diet disrupts the association between insulin resistance and weight gain. Abstract Source: Metabolism. 2009 Aug;58(8):1116-22. Epub 2009 Jun 18. PMID: 19439329 Abstract Author(s): Jose O Leite, Ryan DeOgburn, Joseph C Ratliff, Randy Su, Jeff S Volek, Mary M McGrane, Alan Dardik, Maria Luz Fernandez Article Affiliation: Department of Nutritional Sciences, University of Connecticut, Storrs, CT 06269, USA. Abstract: The cornerstone to treat metabolic syndrome and insulin resistance is dietary intervention. Both low-carbohydrate diet (LCD) and low-fat diet (LFD) have been reported to induce weight loss and improve these conditions. One of the factors associated with a subject's adherence to the diet is satiety. The aim of this study was to evaluate the effects of LCD and LFD on body weight, appetite hormones, and insulin resistance. Twenty guinea pigs were randomly assigned to LCD or LFD (60%:10%:30% or 20%:55%:25% of energy from fat/carbohydrate/protein, respectively) for 12 weeks. Weight and food intake were recorded every week. After this period, animals were killed and plasma was obtained to measure plasma glucose and insulin, appetite hormones, and ketone bodies. Guinea pigs fed LCD gained more weight than those fed LFD. The daily amount of food intake in grams was not different between groups, suggesting that food density and gastric distension played a role in satiety. There was no difference in leptin levels, which excludes the hypothesis of leptin resistance in the LCD group. However, plasma glucagon-like peptide-1 was 47.1% lower in animals fed LCD (P<.05). Plasma glucose, plasma insulin, and insulin sensitivity were not different between groups. However, the heavier animals that were fed LFD had impairment in insulin sensitivity, which was not observed in those fed LCD. These findings suggest that satiety was dependent on the amount of food ingested. The weight gain in animals fed LCD may be related to their greater caloric intake, lower levels of glucagon-like peptide-1, and higher protein consumption. The adoption of LCD promotes a unique metabolic state that prevents insulin resistance, even in guinea pigs that gained more weight. The association between weight gain and insulin resistance seems to be dependent on high carbohydrate intake. Article Published Date : Aug 01, 2009

Role of Ketogenic Diets in Neurodegenerative Diseases (Alzheimer's Disease and Parkinson's Disease).

Related Articles Role of Ketogenic Diets in Neurodegenerative Diseases (Alzheimer's Disease and Parkinson's Disease). Nutrients. 2019 Jan 15;11(1): Authors: Włodarek D Abstract The goal of this review was to assess the effectiveness of ketogenic diets on the therapy of neurodegenerative diseases. The ketogenic diet is a low-carbohydrate and fat-rich diet. Its implementation has a fasting-like effect, which brings the body into a state of ketosis. The ketogenic diet has, for almost 100 years, been used in the therapy of drug-resistant epilepsy, but current studies indicate possible neuroprotective effects. Thus far, only a few studies have evaluated the role of the ketogenic diet in the prevention of Parkinson's disease (PD) and Alzheimer's disease (AD). Single studies with human participants have demonstrated a reduction of disease symptoms after application. The application of the ketogenic diet to elderly people, however, raises certain concerns. Persons with neurodegenerative diseases are at risk of malnutrition, while food intake reduction is associated with disease symptoms. In turn, the ketogenic diet leads to a reduced appetite; it is not attractive from an organoleptic point of view, and may be accompanied by side effects of the gastrointestinal system. All this may lead to further lowering of consumed food portions by elderly persons with neurodegenerative diseases and, in consequence, to further reduction in the supply of nutrients provided by the diet. Neither data on the long-term application of the ketogenic diet in patients with neurodegenerative disease or data on its effects on disease symptoms are available. Further research is needed to evaluate the suitability of the ketogenic diet in the therapy of AD- or PD-affected persons. PMID: 30650523 [PubMed - in process]

Anti-Obesity Properties of the Dietary Green Alga, Codium cylindricum, in High-Fat Diet-Induced Obese Mice.

Related Articles Anti-Obesity Properties of the Dietary Green Alga, Codium cylindricum, in High-Fat Diet-Induced Obese Mice. J Nutr Sci Vitaminol (Tokyo). 2018;64(5):347-356 Authors: Li ZS, Zheng JW, Manabe Y, Hirata T, Sugawara T Abstract Marine carotenoids have been reported to prevent and alleviate lifestyle-related diseases including diabetes and obesity. We previously reported that siphonaxanthin, a green algal carotenoid, effectively suppresses adipogenesis in 3T3-L1 cells and prevents lipid accumulation in mesenteric adipose tissue of KK-Ay mice. Thus, we expect that dietary siphonaxanthin-rich marine green algae may effectively prevent obesity. Here, we assessed the effect of dietary siphonaxanthin-rich green algae (Codium cylindricum) on the development of diet-induced obesity in C57BL/6J mice. The mice were fed a low-fat diet (LF; 7% fat, w/w), a high-fat diet (HF; 35% fat, w/w), or a high-fat diet supplemented with 1% or 5% green algal powder (1GA or 5GA) for 78 d. Our results showed that weights of body and perirenal white adipose tissue (WAT) in the 5GA group were significantly lower than that in the HF group. The mesenteric and total WAT, as well as plasma and hepatic cholesterol concentrations tended to be lower in both the 1GA and 5GA groups compared to the HF group. Dietary green algal powder reduced the expression of lipogenesis-related genes and enhanced the expression of energy expenditure-related genes in the mesenteric WAT. Siphonaxanthin accumulated in the mesenteric WAT may contribute to the prevention of adiposity in mesenteric WAT. Furthermore, the reduction in the weight of WAT was attributed to the inhibitory effect on fat absorption of dietary fiber contained in the green algae. Overall, these results indicated that siphonaxanthin-rich green algae may be beneficial for the prevention of obesity and regulation of lipid metabolism.
