Low Carb Diet Rich in Animal Fat and Protein Increases Risk of Death

Posted on: September 10, 2010

Those who adhered to a diet low in carbohydrates but rich in animal-based fats and proteins increased their risk of death – especially by cancer, according to a study published in the Annals of Internal Medicine, led by Simmons College nutrition professor Teresa Fung, Sc. D.

This study is the first of its kind to demonstrate the link between different types of low carbohydrate diets and mortality. It also sought to determine the long-term impact of low carbohydrate diets, which have been promoted as an effective option for weight loss and improving health.

Conversely, the study found that a diet low in carbohydrates but rich in plant-based fats and proteins was associated with a lower risk of mortality.

Fung, who teaches at the Simmons College School of Health Sciences, led the study with colleagues at the Harvard School of Public Health and Channing Laboratory, Brigham and Women’s Hospital.

“This research indicates that all low carb diets are not the same, and the differences have an indelible impact,” Fung said. “One that is based on plant foods is a better choice than one that is based on animal foods.”

The study is based on two cohorts of participants: more than 85,000 women enrolled in the Nurse’s Health Study (ages 34 to 59) who provided dietary information for 26 years; and more than 44,500 men enrolled the Health Professional’s Follow Up Study (ages 40 to 75) who provided dietary information for 20 years. All participants included in the study were free of heart disease, cancer or diabetes. The Nurses’ Health Study is based at Channing Laboratory, Brigham and Women’s Hospital and the Health Professionals’ Follow-up Study is based at Harvard School of Public Health.

In determining health risk, the study created low carbohydrate scores for the women and men, based on a multi-year evaluation of their diet intake with a focus on the proportion of carbohydrates, and fat and protein – whether derived largely from animal or vegetable-based sources.

During follow ups with the men and women, the study found that those who had a diet made up of more animal-based sources and a low-carbohydrate intake , scored higher for association with “all-cause” mortality and cancer mortality., Those who had a diet made up of more plant-based sources and a low-carbohydrate intake, scored lower for association with “all-cause” mortality, and cancer and cardiovascular mortality.

Participants with a higher animal low carbohydrate score were heavier and were more likely to be smokers, whereas those with a higher vegetable low carbohydrate score consumed more alcohol and whole grains. Variations in lifestyle and other dietary issues, such as smoking status, family history of colorectal cancer, aspirin use, and history of hypertension were controlled in the analyses.

The National Institutes of Health funded the study, “Low-Carbohydrate Diets and All-Cause and Cause-Specific Mortality: Two Cohort Studies.”

Simmons College is a nationally recognized private university located in the heart of Boston. The Simmons School of Health Sciences is a nationally recognized school that includes three graduate programs: nutrition and health promotion, nursing (advanced primary care), and physical therapy.

very good research, very useful for people comenn believing that too much fat in it are proteins, findrxonline few months ago talked about the importance of carbohydrates and which were most important for the development of the human body and the most beneficial for health care.

The study was ridiculously badly done, and doesn’t show what your headline claims.
1) the two diets studied were not low carb, they varied from a low of 185 g carb to over 300 g carbs daily, neither of which is low carb territory.
2) The diet questionnaires were very unreliable.
3) the so-called veg group is noted to have eaten almost as much meat as the meat group.
4) the people who wasted taxpayer money on this study should be embarrassed for their mishandling of scientific enquiry.
