Low-fat dairy foods may help reduce risk of type 2 diabetes

10.05.2005


Study finds men who consume more dairy products have lower incidence of diabetes

The consumption of low-fat dairy foods may reduce men’s risk of developing type 2 diabetes, according to a study in the May 9 issue of Archives of Internal Medicine. The report from researchers at Massachusetts General Hospital (MGH), Harvard School of Public Health (HSPH) and Brigham and Women’s Hospital (BWH) – the first large-scale, prospective examination of a relationship between dairy intake and diabetes risk – analyzes data from the HSPH-based Health Professionals Follow-up Study.

"Our study found that men consuming higher levels of dairy products, especially low-fat dairy foods, had a significantly lower risk of developing type 2 diabetes during a 12-year period," says Hyon Choi, MD, DrPH, director of Outcomes Research in the MGH Rheumatology Unit, the paper’s lead author. "While individuals should consider both the benefits and risks of dairy foods before considering changing their diets, consuming up to two servings daily of low-fat dairy products can probably be recommended for most people."



Lifestyle factors such as diet, exercise and weight are established risk factors for type 2 diabetes. Several recent studies have suggested that dairy consumption may help control weight and blood pressure and reduce the risks of health problems such as coronary artery disease and gout. Other research has implied that dairy foods could help prevent insulin resistance, a precursor of type 2 diabetes. The researchers conducted the current study to directly examine the relationship between dairy consumption and diabetes.
Initiated in 1986, the Health Professionals Follow-up Study has gathered information regarding the relationship between dietary factors and several illnesses from more than 50,000 men employed in the health professions. Every two years participants complete questionnaires regarding their diseases and health-related topics like smoking and exercise, and every four years the questionnaires also collect comprehensive dietary information.

The current study evaluated information from more than 41,000 participants who did not have diabetes, cardiovascular disease or cancer when the study began. Those men who reported developing type 2 diabetes during the study period completed a supplementary survey, which confirmed the diagnosis in about 1,200 participants. The researchers then analyzed the dietary information all participants provided in 1986, 1990 and 1994 to determine how diet related to their risk of developing diabetes.

Results showed that those men consuming higher levels of dairy foods had significantly less risk of developing type 2 diabetes than did those consuming the lowest levels, and further analysis showed the risk reduction was almost exclusively associated with low-fat or non-fat dairy foods. In general, each serving-per-day increase in dairy intake resulted in a 9 percent reduction in the risk of developing the disorder. Controlling for consumption of several other types of food, activity level and family history did not change the association.

"Additional studies will be required both to confirm this relationship and to see if the results apply to women or to men younger than this group, who were in their 50s when they joined the study," says Choi. "Another question to be investigated would be whether adjusting dairy intake could be helpful to people with established type 2 diabetes, and the mechanism behind any relation between dairy intake and diabetes risk also needs to be clarified."

Choi is an instructor in Medicine at Harvard Medical School. His co-authors are senior author Frank Hu, MD, PhD; Walter Willett, MD, DrPH; Meir Stampfer, Md, DrPH; and Eric Rimm, ScD; all of HSPH and the Channing Laboratory at BWH. The study was supported by grants from the National Institutes of Health.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
