Could a high-carb diet cause dementia?

When it comes to brain health, a calorie isn't just a calorie. The calories we get from high-carb foods, like pasta, crackers, and bread, are packed with the simple sugar glucose. In an interview published in Alternative and Complementary Therapies, Dr. David Perlmutter points to recent research that suggests that high levels of glucose could potentially lead to a number of brain disorders like dementia, Alzheimer's, and impaired cognition. "It is a profound correlation to recognize that even subtle elevations of blood glucose—well below levels to be considered diabetic—may already be damaging the brain." Dr. Perlmutter said in the interview. Perlmutter recommends a diet rich in healthy fats, low in carbs, and relatively gluten-free. [DailyMail]

Believing in Hell has a damning effect on your happiness. 

Go figure: Brooding over the fire and brimstone that awaits one's eternal soul can put a serious damper on worldly satisfaction. Research published in PLoS One reviewed an international survey that looked to find out how believing in heaven and hell affects people emotionally. Researchers found that while religious beliefs tended to have positive emotional benefits overall, societies that place more emphasis on the dreary possibility of a hellish afterlife were less happier than those that put more weight behind a belief in heaven.
