    Input: OBJECTIVE Adverse effects of hypercaloric , high-fructose diets on insulin sensitivity and lipids in human subjects have been shown repeatedly . The implication s of fructose in amounts close to usual daily consumption , however , have not been well studied . This study assessed the effect of moderate amounts of fructose and sucrose compared with glucose on glucose and lipid metabolism . RESEARCH DESIGN AND METHODS Nine healthy , normal-weight male volunteers ( aged 21–25 years ) were studied in this double-blind , r and omized , cross-over trial . All subjects consumed four different sweetened beverages ( 600 mL/day ) for 3 weeks each : medium fructose ( MF ) at 40 g/day , and high fructose ( HF ) , high glucose ( HG ) , and high sucrose ( HS ) each at 80 g/day . Euglycemic-hyperinsulinemic clamps with [6,6]-2H2 glucose labeling were used to measure endogenous glucose production . Lipid profile , glucose , and insulin were measured in fasting sample s. RESULTS Hepatic suppression of glucose production during the clamp was significantly lower after HF ( 59.4 ± 11.0 % ) than HG ( 70.3 ± 10.5 % , P < 0.05 ) , whereas fasting glucose , insulin , and C-peptide did not differ between the interventions . Compared with HG , LDL cholesterol and total cholesterol were significantly higher after MF , HF , and HS , and free fatty acids were significantly increased after MF , but not after the two other interventions ( P < 0.05 ) . Subjects ’ energy intake during the interventions did not differ significantly from baseline intake . CONCLUSIONS This study clearly shows that moderate amounts of fructose and sucrose significantly alter hepatic insulin sensitivity and lipid metabolism compared with similar amounts of glucose OBJECTIVE To examine associations between type 2 diabetes and fiber , glycemic load ( GL ) , dietary glycemic index ( GI ) , and fiber-rich foods . RESEARCH DESIGN AND METHODS This was a prospect i ve study of 36,787 men and women aged 40 - 69 years without diabetes . For all self-reported cases of diabetes at 4-year follow-up , confirmation of diagnosis was sought from medical practitioners . Case subjects were those who reported diabetes at follow-up and for whom there was no evidence that they did not have type 2 diabetes . Data were analyzed with logistic regression , adjusting for country of birth , physical activity , family history of diabetes , alcohol and energy intake , education , 5-year weight change , sex , and age . RESULTS Follow-up was completed by 31,641 ( 86 % ) participants , and 365 cases were identified . The odds ratio ( OR ) for the highest quartile of white bread intake compared with the lowest was 1.37 ( 95 % CI 1.04 - 1.81 ; P for trend = 0.001 ) . Intakes of carbohydrate ( OR per 200 g/day 0.58 , 0.36 - 0.95 ) , sugars ( OR per 100 g/day 0.61 , 0.47 - 0.79 ) , and magnesium ( OR per 500 mg/day 0.62 , 0.43 - 0.90 ) were inversely associated with incidence of diabetes , whereas intake of starch ( OR per 100 g/day 1.47 , 1.06 - 2.05 ) and dietary GI ( OR per 10 units 1.32 , 1.05 - 1.66 ) were positively associated with diabetes . These relationships were attenuated after adjustment for BMI and waist-to-hip ratio . CONCLUSIONS Reducing dietary GI while maintaining a high carbohydrate intake may reduce the risk of type 2 diabetes . One way to achieve this would be to substitute white bread with low-GI breads BACKGROUND Because egg yolk has a high cholesterol concentration , limited egg consumption is often suggested to help prevent ischemic heart disease ( IHD ) . OBJECTIVE We epidemiologically examined the validity of this recommendation . DESIGN We analyzed the relations of egg consumption to serum cholesterol and cause-specific and all-cause mortality by using the NIPPON DATA 80 ( National Integrated Project for Prospect i ve Observation of Non-communicable Disease And its Trends in the Aged , 1980 ) data base . At the baseline examination in 1980 , a nutritional survey was performed by using the food-frequency method in Japanese subjects aged > or = 30 y. We followed 5186 women and 4077 men for 14 y. RESULTS The subjects were categorized into 5 egg consumption groups on the basis of their responses to a question naire ( > or = 2/d , 1/d , 1/2 d , 1 - 2/wk , and seldom ) . There were 69 , 1396 , 1667 , 1742 , and 315 women in each of the 5 groups , respectively . Age-adjusted total cholesterol ( 5.21 , 5.04 , 4.95 , 4.91 , and 4.92 mmol/L in the 5 egg consumption categories , respectively ) was related to egg consumption ( P < 0.0001 , analysis of covariance ) . In women , unadjusted IHD mortality and all-cause mortality differed significantly between the groups [ IHD mortality : 1.1 , 0.5 , 0.4 , 0.5 , and 2.0 per 1000 person-years , respectively ( P = 0.008 , chi-square test ) ; all-cause mortality : 14.8 , 8.0 , 7.5 , 7.5 , and 14.5 per 1000 person-years , respectively ( P < 0.0001 , chi-square test ) ] . In men , egg consumption was not related to age-adjusted total cholesterol . Cox analysis found that , in women , all-cause mortality in the 1 - 2-eggs/wk group was significantly lower than that in the 1-egg/d group , whereas no such relations were noted in men . CONCLUSION Limiting egg consumption may have some health benefits , at least in women in geographic areas where egg consumption makes a relatively large contribution to total dietary cholesterol intake BACKGROUND Dietary carbohydrates may influence the development of  type 2 ( non-insulin-dependent ) diabetes  , for example , through effects on blood glucose and insulin concentrations . OBJECTIVE We examined the relations of baseline intake of carbohydrates , dietary fiber , dietary magnesium , and carbohydrate-rich foods and the glycemic index with incidence of diabetes . DESIGN This was a prospect i ve cohort study of 35988 older Iowa women initially free of diabetes . During 6 y of follow-up , 1141 incident cases of diabetes were reported . RESULTS  Total grain , whole-grain , total dietary fiber , cereal fiber , and dietary magnesium intakes  showed strong inverse associations with incidence of diabetes after adjustment for potential nondietary confounding variables . Multivariate-adjusted relative risks of diabetes were 1.0 , 0.99 , 0.98 , 0.92 , and 0.79 ( P for trend : 0.0089 ) across quintiles of whole-grain intake ; 1.0 , 1.09 , 1.00 , 0.94 , and 0.78 ( P for trend : 0.005 ) across quintiles of total dietary fiber intake ; and 1.0 , 0.81 , 0.82 , 0.81 , and 0.67 ( P for trend : 0.0003 ) across quintiles of dietary magnesium intake . Intakes of total carbohydrates , refined grains , fruit and vegetables , and soluble fiber and the glycemic index were unrelated to diabetes risk . CONCLUSION These data support a protective role for grains ( particularly whole grains ) , cereal fiber , and dietary magnesium in the development of diabetes in older women To determine the relations of diet with risk of clinical noninsulin-dependent diabetes , we analyzed data from a prospect i ve cohort of 84360 US women . During 6 y of follow-up we identified 702 definite incident cases . Because body mass index ( BMI ) is a powerful risk factor for diabetes , we examined the relations of fat ( including type ) , fiber , sucrose , and other components of diet to risk of diabetes , among women with BMI s ( in kg/m2 ) less than 29 kg/m2 . After controlling for body mass index , previous weight change , and alcohol intake , we observed no associations between intakes of energy  , protein , sucrose ,  carbohydrate  ,  or fiber and risk of diabetes . Compared with women in the lowest quintile of energy-adjusted intake , and relative risks ( and tests for trend ) for those in the highest quintile were 0.61 ( P trend = 0.03 ) for vegetable fat , 0.62 ( P trend = 0.008 ) for potassium , 0.70 ( P trend = 0.005 ) for calcium , and 0.68 ( P trend = 0.02 ) for magnesium . These inverse associations were attenuated among obese women ( BMI s greater than or equal to 29 ) BACKGROUND The consumption of sucrose-sweetened soft drinks ( SSSDs ) has been associated with obesity , the metabolic syndrome , and cardiovascular disorders in observational and short-term intervention studies . Too few long-term intervention studies in humans have examined the effects of soft drinks . OBJECTIVE We compared the effects of SSSDs with those of isocaloric milk and a noncaloric soft drink on changes in total fat mass and ectopic fat deposition ( in liver and muscle tissue ) . DESIGN Overweight subjects ( n = 47 ) were r and omly assigned to 4 different test drinks ( 1 L/d for 6 mo ) : SSSD ( regular cola ) , isocaloric semiskim milk , aspartame-sweetened diet cola , and water . The amount of intrahepatic fat and intramyocellular fat was measured with (1)H-magnetic resonance spectroscopy . Other endpoints were fat mass , fat distribution ( dual-energy X-ray absorptiometry and magnetic resonance imaging ) , and metabolic risk factors . RESULTS The relative changes between baseline and the end of 6-mo intervention were significantly higher in the regular cola group than in the 3 other groups for liver fat ( 132 - 143 % , sex-adjusted mean ; P < 0.01 ) , skeletal muscle fat ( 117 - 221 % ; P < 0.05 ) , visceral fat ( 24 - 31 % ; P < 0.05 ) , blood triglycerides ( 32 % ; P < 0.01 ) , and total cholesterol ( 11 % ; P < 0.01 ) . Total fat mass was not significantly different between the 4 beverage groups . Milk and diet cola reduced systolic blood pressure by 10 - 15 % compared with regular cola ( P < 0.05 ) . Otherwise , diet cola had effects similar to those of water . CONCLUSION Daily intake of SSSDs for 6 mo increases ectopic fat accumulation and lipids compared with milk , diet cola , and water . Thus , daily intake of SSSDs is likely to enhance the risk of cardiovascular and metabolic diseases . This trial is registered at clinical trials.gov as NCT00777647 IMPORTANCE Epidemiologic studies have suggested that higher intake of added sugar is associated with cardiovascular disease ( CVD ) risk factors . Few prospect i ve studies have examined the association of added sugar intake with CVD mortality . OBJECTIVE To examine time trends of added sugar consumption as percentage of daily calories in the United States and investigate the association of this consumption with CVD mortality . DESIGN , SETTING , AND PARTICIPANTS National Health and Nutrition Examination Survey ( NHANES , 1988 - 1994 [ III ] , 1999 - 2004 , and 2005 - 2010 [ n = 31,147 ] ) for the time trend analysis and NHANES III Linked Mortality cohort ( 1988 - 2006 [ n = 11 733 ] ) , a prospect i ve cohort of a nationally representative sample of US adults for the association study . MAIN OUTCOMES AND MEASURES Cardiovascular disease mortality . RESULTS Among US adults , the adjusted mean percentage of daily calories from added sugar  increased from 15.7 % ( 95 % CI , 15.0%-16.4 % ) in 1988 - 1994 to 16.8 % ( 16.0%-17.7 % ; P = .02 ) in 1999 - 2004 and decreased to 14.9 % ( 14.2%-

We conclude based on high quality evidence from r and omized controlled trials ( RCT ) , systematic review s and meta-analyses of cohort studies that singling out added sugars as unique culprits for metabolically based diseases such as obesity , diabetes and cardiovascular disease appears inconsistent with modern , high quality evidence and is very unlikely to yield health benefits .
While it is prudent to consume added sugars in moderation , the reduction of these components of the diet without other reductions of caloric sources seems unlikely to achieve any meaningful benefit
