Dairy Products Reduce Diabetes Risk
Milk and other dairy products are often recommended to limit the consumption, especially those high in fat. But the latest study says dairy products contain fatty acids that can prevent diabetes mellitus.
Fatty acids, called trans-palmitoleic acid in high amounts in the body will reduce risk of diabetes by 62 percent. According to a study reported in the Annals of Internal Medicine journal.
“People which have high content of trans-palmitoleicnya fatty acid also have higher levels of good cholesterol and triglycerides. This will reduce insulin resistance and lower levels of inflammation markers,” said lead researcher Dr.Dariush Mozaffarian of Brigham and Women’s Hospital and Harvard School of Public Health, according to Healthday News.
Palmitoleic acid is actually found naturally in the human body. These acids are also found in dairy products even though the numbers are small. The source of this acid that comes from outside the body is referred as trans-palmitoleic acid. Milk high in fat has a higher acid levels than non-fat milk.
Studies in animals show palmitoleic acid protects the body from insulin resistance. Similarly, in humans. But experts have not been able to find the exact cause.
For this, Mozaffarian and colleagues analyzed data from 3,700 people who followed Cardiovascular Health Study. All respondents are aged 65 years and over and lives in the United States.
Blood samples of the respondents were checked to determine the amount of trans-palmitoeic acid levels as well as cholesterol, triglycerides, C-reactive protein and glucose levels. The respondents were also interviewed about their daily consumption patterns.
People who have high levels of trans-palmitoleic acid appeared to have low levels of fat in the body. They also have higher levels of good cholesterol and low bad cholesterol. Meanwhile, levels of C-reactive protein (a marker of inflammation) is low.
And as expected levels of insulin resistance in their body are lower. This means their risk for type 2 diabetes is lower.
Although the result of this study found links between milk consumption with a lower risk of diabetes, experts who responded to this study says there is no single study that can be used as a guide of diet for the community.
But experts said the results of this study show that not all high-fat products is bad for health.
