Good fat exists: "brown" cells protect against obesity and diabetes by filtering out harmful proteins, a study reveals
- Brown fat, also called brown fat, converts food into body heat
- The researchers found that it also filters the amino acids called BCAA from blood that have been linked to diabetes and obesity
- People with little or no brown fat have not been able to screen BCAA's as well as those with high levels of brown fat.
It is true that not all fats are equal and that some fats can actually help us fight diabetes and obesity.
Scientists from Rutgers University, New Jersey, have discovered exactly how so-called brown fat is beneficial to our health.
Also known as brown adipose tissue, the main role of brown fat is to transform the food we eat into body heat.
The researchers learned that brown fat also filters out amino acids that can accumulate in the body, increasing the risk of diabetes and obesity.
But when people have little or no brown fat, their body does not purge this amino acid, making them more vulnerable to these chronic diseases.
A new study from Rutgers University has revealed that brown fat is essential for filtering the amino acids called blood BCAAs that have been linked to diabetes and obesity (image of the file).
Brown fat burns calories when it is activated by cool temperatures to generate body heat.
It is usually found in the neck and upper back, as well as around the kidneys and spinal cord.
Humans lose most of the brown fats after childhood, but they can be generated through exercise, restorative sleep, and frequent exposure to cold weather.
Studies have shown that adults with lower body mass index and normal blood sugar tend to have more brown fat.
The new study, published in Nature, revealed that brown fat helps the body filter the blood of so-called branched-chain amino acids (BCAA).
These proteins are not naturally produced by the body and can be found in foods such as eggs, fish, meat and milk.
BCAAs are commonly added to supplements because they have been known to help build muscle and reduce muscle soreness.
The usual doses for women are three to five grams a day and 15 to 20 grams a day for men.
However, in excessive amounts, BCAAs have been associated with abnormal blood glucose levels, diabetes, liver disease, and obesity.
The researchers found that people with little or no brown hair were not able to eliminate BCAAs from their blood as effectively as those with high blood counts.
"Our study explains the paradox that BCAA supplements can potentially benefit people with active brown fat, such as healthy people," said co-author, Dr. Labros Sidossis, director of the Department of Kinesiology and of Rutgers University.
"But this can be detrimental for others, including the elderly, obese people and people with diabetes."
For future research, the team is considering whether environmental factors – such as eating spicy food – or medications can control BCAAs filtering brown fat from the blood.
Dr. Sidossis said that this could lead to targeted drug therapies to help fight type 2 diabetes and obesity.
