The correlation between the prevalence of brown fat and enhanced cardiac or metabolic health has been verified by recent research, the largest of its type ever undertaken in humans.
The study validates the relatively recent theory proposing that large health benefits are provided by adipose tissue, generally referred to as brown fat.
A few various types of fat tissue are housed in the body. However, the most typical ones are white fat. They are the fat cells we are both working on getting rid of because they are the kind that makes up the overwhelming majority of our body's fat cells.
On the other side, brown fat is widely considered to be much more metabolically active, consisting of higher concentrations of mitochondria rich in iron that enable the body to burn it off easily. Brown fat is present in babies in high volumes. Still, it was assumed until recently that we lost the potential to produce it when we get older.
Valuable Resource
Researchers found in 2009 that brown fat is still available in limited quantities in adults. As a cure for obesity and other diseases, this finding sparked a surge of the study exploring how to make white fat brown.
The difficulties in detecting this specific form of adipose tissue was one problem that slowed down research into the potential beneficial benefits of brown fat. The first author of the current research, Tobias Becher, states that brown fat can only be detected using PET scans, rendering it impossible to perform mass population surveys.
These scans, Becher said, are costly and use radiation. He added that specialists don't want to expose several stable individuals to it.
The study examined evidence from more than 50,000 vets who had received PET scans for regular cancer assessment to provide an overview of the impact of brown fat on a broad population scale. The researchers could accurately compare brown fat with a variety of cardio-metabolic disorders after controlling for the effects of individual cancer forms and phases.
The findings indicated that a lower incidence of many chronic conditions was correlated with brown fat inclusion. Such subjects with current brown fat were considerably less likely to develop type 2 diabetes. Lower rate of hypertension and heart diseases were also linked with brown fat.
Although obesity is normally correlated with reduced brown fat function, the researchers said that certain obese people who maintain brown fat operation seem to be shielded from excess weight-related conditions. They added that the notion also promotes brown fat's ability as a clinical aim outside weight reduction itself and distinguishes obesity from illness.
Is Brown Fat More Than An Energy Burning Powerhouse?
While scientists know that brown fat is used far more easily by the body as an energy source, it is still uncertain if it will produce wider health benefits. One result that indicates brown fat could do more than only burn calories quicker than white fat is the correlation with lower rates of hypertension.
Another researcher working on the current report, Paul Cohen, clarified that they are contemplating the likelihood of brown fat tissue doing more than eating glucose and burning calories, and even potentially taking part in hormonal signaling to other organs.
Over the past few years, a vast amount of study has concentrated on discovering ways to either encourage the body to generate more brown fat or transform pre-existing white fat into its more metabolically advantageous cousin. The approaches suggested include everything from exercise-like hormones, nanoparticle injections, medications, and even gene therapy that might function like a "fat switch."
The researchers published the new study in the journal Nature Medicine.
