Sugar should be controlled like alcohol and tobacco to protect public health, according to a team of UCSF researchers, who maintain in a new report that sugar is fueling a global obesity pandemic, contributing to 35 million deaths annually worldwide from non-communicable diseases like diabetes, heart disease and cancer.

Muscle force and functional capacity generally decrease with aging in the older population, although this effect can be reversed, attenuated, or both through strength training. Fish oil (FO), which is rich in n–3 (omega-3) PUFAs, has been shown to play a role in the plasma membrane and cell function of muscles, which may enhance the benefits of training. The effect of strength training and FO supplementation on the neuromuscular system of the elderly has not been investigated.

Age-related delays in neural timing are not inevitable and can be avoided or offset with musical training, according to a new study from Northwestern University. The study is the first to provide biological evidence that lifelong musical experience has an impact on the aging process.

A study recently published in Nature Genetics has found new evidence for a link between the body clock hormone melatonin and type 2 diabetes. The study found that people who carry rare genetic mutations in the receptor for melatonin have a much higher risk of type 2 diabetes.

Researchers involved in the Mayo Clinic Study of Aging report that more than 6 percent of Americans age 70 to 89 develop mild cognitive impairment (MCI) every year. Also, the condition appears to affect men and those who only have a high school education more than women and those who have completed some higher education. People with MCI are at the stage between suffering the normal forgetfulness associated with aging and developing dementia, such as that caused by Alzheimer's disease.

Eating food fried in olive or sunflower oil is not linked to heart disease or premature death, finds a paper published in the British Medical Journal online (bmj.com). The authors stress, however, that their study took place in Spain, a Mediterranean country where olive or sunflower oil is used for frying...

A pilot study suggests infrared analysis of white blood cells is a promising strategy for diagnosis of Alzheimer's disease. Spanish researchers, led by Pedro Carmona from the Instituto de Estructura de la Materia in Madrid, have uncovered a new promising way to diagnose Alzheimer's disease more accurately.

A study by academics at Northumbria University has shown for the first time that trekking-poles help hikers maintain muscle function while significantly reducing soreness in the days following a hike. In the study, 37 physically active men and women were split into two groups of equal fitness and asked to hike up and down Snowdon, the highest mountain in England and Wales.

Protein -- not sugar -- stimulates cells keeping us thin and awake, a new study suggests. A new study has found that protein and not sugar activates the cells responsible for keeping us awake and burning calories. The research, published in the Nov. 17 issue of the scientific journal Neuron, has...

There is no doubt that eating a balanced diet is essential for maintaining a healthy body weight as well as appropriate arousal and energy balance, but the details about how the nutrients we consume are detected and processed in the brain remain elusive. Now, a research study discovers...
