Link Between Poverty and Obesity A Recent Phenomenon

It’s a well-established fact that poor people in America are disproportionately affected by obesity, but a new study reveals that this relationship is only about 30 years old.
“We found that the relationship between low income and high rates of adult obesity in the U.S. is not observable until the early 1990s,” said co-author Dr. Alex Bentley, head of the Department of Anthropology at the University of Tennessee at Knoxville. “As recently as 1990, this was not a detectable problem.”

How Folate Deficiency Ties In to Mental Health Disorders, Infertility

Folate deficiency has been associated with mental illness, age-related dementia, infertility and fetal deformation of the brain and spinal cord (neural tube defects).

Probiotic Treatment May Benefit Bipolar Patients

Probiotic treatment may help alleviate some symptoms of bipolar disorder, according to a new study by researchers at Sheppard Pratt Health System in Baltimore, Maryland.
The findings show that previously hospitalized bipolar patients who were given a probiotic supplement stayed out of the hospital longer and required less in-patient treatment time compared to a placebo group. The most dramatic improvements were seen in patients with the highest levels of gut inflammation at the beginning of the study.
