Dairy Products Contain Fatty Acids That Reduce The Risk Of Developing Type 2 Diabetes

Dairy Products Contain Fatty Acids That Reduce The Risk Of Developing Type 2 Diabetes.
New scrutinization suggests that whole-fat dairy products - ordinarily shunned by healthfulness experts - contain a fatty acid that may discount the risk of type 2 diabetes. The fatty acid is called trans-palmitoleic acid, according to the burn the midnight oil in the Dec 21, 2010 issue of the Annals of Internal Medicine, and commonality with the highest blood levels of this fatty acid reduce their odds of diabetes by 62 percent compared to those with the lowest blood levels of it. In addition, "people who had higher levels of this fatty acid had better cholesterol and triglyceride levels, soften insulin stubbornness and lower levels of mutinous markers," said study author Dr Dariush Mozaffarian, co-director of the program in cardiovascular epidemiology at Brigham and Women's Hospital and Harvard School of Public Health.

Circulating palmitoleic acid is found honestly in the benign body. It's also found in small quantities in dairy foods. When it's found in sources longest the human body, it's referred to as trans-palmitoleic acid. Whole draw off has more trans-palmitoleic acid than 2 percent milk, and 2 percent milk has more of this fatty acid than does glide milk. "The amount of trans-palmitoleic acid is proportional to the amount of dairy fat," said Mozaffarian.

Animal studies of the needless to say occurring palmitoleic acid have previously shown that it can watch over against insulin resistance and diabetes, said Mozaffarian. In humans, research has suggested that greater dairy consumption is associated with a lessen diabetes risk. However, the reason for this association hasn't been clear.

To assess whether this overlooked and rather rare fatty acid might contribute to dairy's unmistakable protective effect, the researchers reviewed data from over 3700 adults enrolled in the Cardiovascular Health Study. All of the participants were over 65 and lived in one of four states: California, Maryland, North Carolina and Pennsylvania.

Blood samples were analyzed for the mien of trans-palmitoleic acid, as well as cholesterol, triglycerides, C-reactive protein and glucose levels. Participants also provided poop on their usual diets.

People with higher levels of trans-palmitoleic acid had measure less well-to-do on their bodies, according to the study. They also had higher "good" cholesterol levels and put down overall cholesterol levels. They had lower levels of C-reactive protein, a marker of inflammation. And they showed signify of lower levels of insulin resistance, according to the study.

Most significantly, however, those with higher trans-palmitoleic acid levels had reduce odds of developing type 2 diabetes. Those with the highest levels of trans-palmitoleic acid reduced their advantage of type 2 diabetes by nearly two-thirds. Mozaffarian said it's abstruse to know exactly how many servings of dairy it would take to get to the highest levels of trans-palmitoleic acid, but said it was favoured three to five servings a day, depending on the class of dairy consumed.

However, he said, it's too soon to make any dietary recommendations based on the results of just this finding. "This con confirms that something about dairy is linked very strongly to a lower jeopardize of diabetes, but no single study should be enough to change guidelines," he said, adding that he hopes this study will induce more research.

Dr Sue Kirkman, senior vice president of medical affairs and community message for the American Diabetes Association, agreed that it's too soon to change dietary guidelines, but said the findings do suggest "that things may be more Byzantine than we might simplistically think. It looks like we can't rephrase all trans-fats are bad, as this one was associated with decreases in diabetes, insulin resistance and C-reactive protein levels".

Dr Joel Zonszein, chief honcho of the Clinical Diabetes Center at Montefiore Medical Center in New York City, concurred, noting, "this was a very nice, and very robust, association. Maybe strong exploit isn't so bad, but I don't think there's enough evidence to show that we should start drinking total milk. We need to understand the mechanism behind this association review. Dietary changes in this power tend to be to extremes, but this study should not be used to make changes in the diet; it's just an observation suitably now".
