Low-Carbohydrate Diets and All-Cause and Cause-Specific Mortality
http://www.annals.org/content/153/5/289.abstract
Abstract Background: Data on the long-term association between low-carbohydrate diets and mortality are sparse. Objective: To examine the association of low-carbohydrate diets with mortality during 26 years of follow-up in women and 20 years in men. Design: Prospective cohort study of women and men who were followed from 1980 (women) or 1986 (men) until 2006. Low-carbohydrate diets, either animal-based (emphasizing animal sources of fat and protein) or vegetable-based (emphasizing vegetable sources of fat and protein), were computed from several validated food-frequency questionnaires assessed during follow-up. Setting: Nurses' Health Study and Health Professionals' Follow-up Study. Participants: 85 168 women (aged 34 to 59 years at baseline) and 44 548 men (aged 40 to 75 years at baseline) without heart disease, cancer, or diabetes. Measurements: Investigators documented 12 555 deaths (2458 cardiovascular-related and 5780 cancer-related) in women and 8678 deaths (2746 cardiovascular-related and 2960 cancer-related) in men. Results: The overall low-carbohydrate score was associated with a modest increase in overall mortality in a pooled analysis (hazard ratio [HR] comparing extreme deciles, 1.12 [95% CI, 1.01 to 1.24]; P for trend = 0.136). The animal low-carbohydrate score was associated with higher all-cause mortality (pooled HR comparing extreme deciles, 1.23 [CI, 1.11 to 1.37]; P for trend = 0.051), cardiovascular mortality (corresponding HR, 1.14 [CI, 1.01 to 1.29]; P for trend = 0.029), and cancer mortality (corresponding HR, 1.28 [CI, 1.02 to 1.60]; P for trend = 0.089). In contrast, a higher vegetable low-carbohydrate score was associated with lower all-cause mortality (HR, 0.80 [CI, 0.75 to 0.85]; P for trend ≤ 0.001) and cardiovascular mortality (HR, 0.77 [CI, 0.68 to 0.87]; P for trend 0.001). Limitations: Diet and lifestyle characteristics were assessed with some degree of error. Sensitivity analyses indicated that results were probably not substantively affected by residual confounding or an unmeasured confounder. Participants were not a representative sample of the U.S. population. Conclusion: A low-carbohydrate diet based on animal sources was associated with higher all-cause mortality in both men and women, whereas a vegetable-based low-carbohydrate diet was associated with lower all-cause and cardiovascular disease mortality rates.

Low-Carbohydrate Diets and All-Cause and Cause-Specific Mortality
This "study" was based on self reporting of consumption, very unreliable.
In addition, the diet aimed for was far higher in carbs than any of us consider low carb.

This study seems to fly in the face of Inuit health on an all meat diet, before trading posts exposed them to processed carbohydrates. -- - Billy "Fascism should more properly be called corporatism because it is the merger of state and corporate power." - Benito Mussolini. http://www.democracynow.org/2010/7/2/maude http://english.aljazeera.net/video/m...515308172.html |

Primary Funding Source: National Institutes of Health. Presumably, most people who go on a low-carb diet are overweight or obese to begin with and likely to have a higher mortality anyway. Was that controlled for? We know most people who go on diets are unsuccessful. Do we know how long the low-carbers stayed on their diets? Were they obese at death? |

You expect the lies in politics but I guess science has been taken over by
politics. At least the real low carbers are on the watch and have some legitimate studies to come back with.

At least in the medical fields and probably any others that engender lots of
public interest. "FOB" wrote in message ... You expect the lies in politics but I guess science has been taken over by politics.
