High-Fat Diet Linked to Anxiety, Depression
November 9th, 2015; By Liam Davenport
Consuming a high-fat diet may cause brain changes that lead to anxiety and depression, and although switching to a healthy diet reverses metabolic changes, mood problems persist, preliminary research suggests.
Results of the mouse study showed that a high-fat diet is linked to type 2 diabetes and anxiety and depression and that such a diet blunts the beneficial effect of antidepressants.
The researchers found that there was a correlation between the development of metabolic symptoms and a high-fat diet and anxiogenic/depression-like symptoms, which increased over time.
Nine Risk Factors May Explain Two Thirds of AD Cases
September 1st, 2015
Nine potentially modifiable risk factors may explain two thirds of Alzheimer's disease (AD) cases globally, according to a comprehensive meta-analysis of published studies.
Risk factors include obesity, carotid artery narrowing, low educational achievement, hyperhomocysteine, depression, hypertension, frailty, current smoking, and type 2 diabetes (diabetes only in Asian populations).
According to the analysis, the population attributable risk (PAR) for each of the factors individually ranged from 0.175% to 24.5%, while a model combining all nine factors yielded a PAR of 66%.
