Milk ingredient may protect against obesity

A natural ingredient found in milk may protect people against obesity, even consuming a high-fat diet, according to a research project. The study, conducted by researchers at the École Polytechnique Fédérale de Lausanne, Switzerland, and at Cornell University in New York, found that mice fed with high doses of nicotinamide ribosídeo (NR) together with foods high in fat, burned more fat and were protected against obesity. 

The mice fed with NR gained 60% less weight than animals fed with the same diet without supplementation of NR. The rats that consumed the NR also become better runners thanks to greater muscular endurance. 

Research has shown that the NR precursor of NAD +, enhances the oxidative metabolism and protect against induction of obesity by high fat diets, indicating that NR can also play an important role in prevention of weight gain and diabetes other mammals, including humans. 

"Scientists hypothesized that these effects are the result of an improvement in mitochondrial function. Another investigation, they were able to show that supplementation with NR indirectly stimulated the activity of sirtuin enzymes. These enzymes improve metabolic functions associated with mitochondria such as the burning of lipids and cellular oxidative capacity, "the École Polytechnique Fédérale. 

"These benefits are not the only advantages of this 'hidden vitamin.' The fact that is present naturally in many foods become significantly easier for people to accept their use in nutritional or therapeutic context." 

Investigators said that at present, it is still impossible to determine the amount of milk that a person would need to effectively consume these advantages, in that investigators have not yet been able to measure the concentration of NR in milk. As a result, it is more likely that the NR serve as a new type of supplement to improve metabolism.
