BOSTON, Sept. 8 /PRNewswire-USNewswire/ -- 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."

I've seen this posted everywhere... people should investigate to see what the actual study involved.

Can any guru's here comment on this study,

Would really would like to here what you folks have to say.

The Daily Lipid: New Study Shows that Lying About Your Hamburger Intake Prevents Disease and Death When You Eat a Low-Carb Diet High in Carbohydrates

Also read the linked critique(second paragraph) which shows in pretty good detail what they considered low carb diets.

 

[PHIL HERNON]

Yes

I believe it and it has been known for a long time........BUT, you can be healthier with the grass fed beef, free range chickens, free salmon...........but stick to plant sources for fats if possible. Low carb diets miss too many phytonutrients......I would never recommend it

 

[Cosmicdrifter]

This is nothing new; vegetarian cultures have greater longevity than those who take in high protein, saturated fats, and simple carbohydrates. Seventh Day Adventists live on average about 6 years longer than meat eaters.

The longest lived people on the planet, the Okinawans, eat low calorie diets with mostly fish and vegetables - plus they are very active (manual labor).

It does not take a rocket scientist to accept the premise that eating a crappy diet is not going to optimize your longevity.

On the other hand, studies of centenarians in the US indicate that genetics overrule most every other variable. People that are destined to live long do so irrespective of what they drink, eat, smoke, or whether they exercise.

These studies are so vague and frequently unscientific. Unless the test subjects were seriously into health and their diet, I'm doubtful that they consistently kept to their low carb diet and consistently were more heavily weighted toward plant vs. animal based sources or vice versa.

And what about all the other permutations as a good comparison and baseline, such as high carb/high protein/low fat, etc. (Again just an example). At the end of the day, the low carb/high protein (primarily from animal-based sources) may be the second best option when compared to the other possible combinations. I'm just saying that these studies are only one little piece of a much, much bigger picture.

I know people likely won't click on the link in my post... but as a short snippet the average carb intake among the low carb groups was between 35 and 60% of their calories.

whaaaaat?!?!?!?

Jeez I might as well just play russian roulette then because those "low" carb numbers would make me a whale ha (60% low?!)

 

[PHIL HERNON]

Well

After tracking my blood work every 3 months for 20 years gives me an indication as to what is the healthiest way to eat.

I'd hate to find out what high carb means.

I read it and it was very interesting.
