How To Boost Fat Loss - Does a Low-Fat Dairy Habit Boost Parkinson's Risk?
Thursday, (HealthDay News) - Although you may think that eating low-fat dairy foods is a healthy movement, the new research suggests that the habit is linked to a slight increase in risk to develop Parkinson's disease.
Experts who reviewed the study pointed out that the discoveries are preliminary - the effect was modest and the research was not designed to prove cause and effect.
In the study, researchers analyzed data on about 130,000 men and women, tracing their eating habits every four years and the number of people diagnosed with Parkinson.
After 25 years, more than 1,000 people developed Parkinson, a progressive neurodegenerative disease that affected coordination and movement.
Those who consumed at least three parts of low-fat dairy dairy daily had a 34% greater risk of gaining the disorder than those who only consumed one day. Looking specifically to the consumption of milk, the researchers found that drinking more than a portion of low-fat milk or skim daily were also linked to a larger 39% chanceinson's development. (Low fat also included nonfat).
No such association was seen with the consumption of fatty dairy products such as integral milk.
Even so, the researchers said it was crucial to put the risk in perspective.
It is important to note that the risk of Parkinson's disease is still low, even among people in our study that consumed larger amounts of dairy or low-fat milk, "said study author Katherine Hughes , Harvard Thingen School of Public Health in Boston.
from 5.830 people who ate at least three portions per day of low fat dairy, only 1 percent (60 people), developed Parkinson during The quarter of the above century. To compare, from more than 77,000 who ate less than one day service, only 0.6 percent (483 people), received the diagnosis.
While the researchers found a Link, the findings did not have proven that eating dairy products makes Parkinson's.
"This was an observational study, as well as any observational study, there is the potential of bias," Hughes observed. For example, the risk could actually be due to some third factor related to Dairy ingestion and disease risk. To rule out this possibility, researchers controlled to other factors that affect the risks, such as drinking coffee, which has been connected at the lowest risk of Parkinson.
Researchers can not explain the link for sure. According to Hughes, a possible explanation is that the milk protein reduces the blood level of the urge, a substance derived from the uric acid excreted in the urine. Some surveys show that relatively high levels of Uratos (but not high enough to cause the condition known as drop) are linked to a lower risk of Parkinson.
Contaminants in dairy products, such as pesticides, also throw a paper, added Hughes.
Researchers can not say for sure why they found no link to fatty dairy, but said it could be that the fighting effects of saturated fats in saturated fats in high fat dairy can help A protective urge level.
The discoveries add weight to previous discoveries of laboratory research, said James Beck, scientific director of the Parkinson Foundation. But, he also warned that "all that they are able to do is draw a correlation", and not prove cause and effect.
"I would suggest that people did not change their diets dramatically," Beck said. "This is a modest increase at risk for a disease that, when you look at the general population, is still relatively rare."
Getting enough calcium of dairy products is important for other health reasons, Beck added, how to maintain bone health. A representative of the dairy industry also pointed to the other Benefits of Dairy, including a reduced risk of both heart disease and type 2 diabetes, and lower blood pressure.
A balanced and rich diet in nutrients, representative of all food groups - including dairy - while emerging science unfolds, "said Chris Cifelli. He is a vice president of nutrition research on the National Council of Leitians.
Cifelli added that "total dairy intake was not significantly associated" at the risk of Parkinson, and that only an association was shown between the two.
The study was funded by the US National Institutes of Health and the US Department of Defense. Online June 7 was published in Neurology magazine.
About 1 million people were diagnosed with Parkinson in the United States, according to Parkinson's foundation, and 60,000 new cases are diagnosed daily.
