Brown fat is that magical tissue that you would want more of. Unlike white fat, which stores calories, brown fat burns energy and scientists hope it may hold the key to new obesity treatments. But it has long been unclear whether people with ample brown fat truly enjoy better health. For one thing, it has been hard to even identify such individuals since brown fat is hidden deep inside the body.

Now, a new study in Nature Medicine offers strong evidence: among over 52,000 participants, those who had detectable brown fat were less likely than their peers to suffer cardiac and metabo...

Ridlon and endocrinologist David Morris explain the mechanism that links gut bacteria to hypertension in humans.

1 in 3 American adults suffers from high blood pressure, or hypertension. The disease can be passed down in families, and certain lifestyle factors such as smoking, high-sodium diets, and stress can increase the risk. In recent years, scientists have discovered that certain gut bacteria may contribute to hypertension, as well. In a few studies, when gut bacteria were killed off with antibiotics, patients with hypertension saw a drop in blood pressure. And when gut bacteria were transplanted from hypertensive people into normal mice, they developed high blood pressure...

Eosinophils stimulate β3 adrenoreceptors through the release of soluble factors.

Immune cells which are reduced in number by obesity could be a new target to treat diseases such as type 2 diabetes and hypertension that affect overweight people, according to a collaborative study between The University of Manchester, Lund University and the University of Salford. In a study published in the journal Scientific Reports, reseachers investigated eosinophils. Eosinophils are present in perivascular adipose tissue (PVAT), which surrounds blood vessels and helps to maintain normal blood vessel function by reducing artery contraction.

The current research found that eosinophils were considerably reduced in the PVAT in obesity in mice, and that the PVAT function was severely impaired, contributing ...

Hypertension was associated with exposure to some air pollutants commonly associated with the burning/combustion of fossil fuels, dust and dirt, a new study shows. Researchers suggest people – especially those with high blood pressure – limit their time outdoors when pollution levels are high. “In our analysis of 17 previously-published studies we discovered a significant risk of developing high blood pressure due to exposure to air pollution,” said Tao Liu, Ph.D. “People should limit their exposure on days with higher air pollution levels, especially for those with high blood pressure, even very short-term exposure can aggravate their conditions.”

They performed a meta-analysis of available published studies in the world assessing health effects of all air pollution on HT risk...
