deviation from traditional diet causing disease Are obesity, diabetes, cardiovascular illnesses and more the result of a "mismatch" between the meals we eat and the foods our bodies are prepared for?

"No one diet is universa..
Individual suicide risk can be dramatically altered by social 'sameness,' The study, published in the Proceedings of the National Academy of Sciences, examined the relationship between suicide and social "sameness"—living in communities with other individuals who share common social characteristics, such as employment and marital status, ethnicity or place of birth.Researchers found that social similarity reduced well-known individual risks of suicide for those younge..
depression and immune response An inflammatory autoimmune response within the central nervous system similar to one linked to neurodegenerative diseases such as multiple sclerosis (MS) has also been found in the spinal fluid of healthy people, according to a new Yale-led study comparing immune system cells in the spinal fluid of MS patients and healthy subjects. The research, published Sept. 18 in the journal Science Immunolo..
어른이 되었을 때의 사회생활과 어릴 때 스트레스의 관계 When baboons experience trauma in early life, they have higher levels of stress hormones in adulthood—a potential marker of poor health—than their peers who don't experience trauma, even if they have strong social relationships as adults, according to a study led by a University of Michigan researcher. The study examined the links between childhood adversity, adult social relationships and gluco..

Beginning in the 1990s, Ehleringer, distinguished professors Denise Dearing and Thure Cerling and colleagues started loo..
장수와 철분의 관계 The international study using genetic data from more than a million people suggests that maintaining healthy levels of iron in the blood could be a key to ageing better and living longer. The team pinpointed ten regions of the genome linked to long lifespan, healthspan and longevity. They also found that gene sets linked to iron were overrepresented in their analysis of all three measures of age..
운동이 몸에 주는 영향 Exercise is one of the best-studied and most powerful ways of protecting the brain from age-related cognitive decline and has been shown to improve cognition in individuals at risk of neurodegenerative disease such as Alzheimer's disease and frontotemporal dementia—even those with rare gene variants that inevitably lead to dementia. But many older adults are not able to exercise regularly due to..
