Globally, about 42 million people now have dementia, with Alzheimer’s disease as the most common type of dementia. Rates of Alzheimer’s disease are rising worldwide. The most important risk factors seem to be linked to diet, especially the consumption of meat, sweets, and high-fat dairy products that characterize a Western Diet. For example, when Japan made the nutritional transition from the traditional Japanese diet to the Western diet, Alzheimer’s disease rates rose from 1% in 1985 to 7% in 2008, with rates lagging the nutrition transition by 20-25 years. The evidence of these risk factors, which come from ecological and observational studies, also shows that fruits, vegetables, grains, low-fat dairy products, legumes, and fish are associated with reduced risk. “Using Multicountry Ecological and Observational Studies to Determine Dietary Risk Factors for Alzheimer's Disease,” a review article from the Journal of the American College of Nutrition presents the data.
The treatment of concussions and traumatic brain injury (TBI) is a clinical challenge. Clinical studies thus far have failed to identify an effective treatment strategy when a combination of targets controlling aspects of neuroprotection, neuroinflammation, and neuroregeneration is needed. According to emerging science and clinical experience, aggressive intake of omega-3 fatty acids (n-3FA) seems to be beneficial to TBI, concussion, and post-concussion syndrome patients. This research is presented in "Concussions, Traumatic Brain Injury, and the Innovative Use of Omega-3s", a review article from the Journal of the American College of Nutrition, official publication of the American College of Nutrition.
The increasing proportion of the population who prefer to remain childless is a major social problem for many European countries. However this trend has not (so far) been the result of the expansion of education. This is the conclusion of new research, published in the journal Population Studies.
Understanding what counts as an addiction, and what can be done to address it is the work of researchers across many disciplines. But what tools are used to ‘measure’ addiction, and are these capable of legitimising an addiction or improving our knowledge of it?
