Explosive book claims cereal destroys your brain


Neurologist says grains can cause dementia, headaches and depression.

EVERY time you tuck into a bowl of cereal or plate of pasta, you're killing your brain. That's the dramatic diagnosis of a US neurologist whose recently published New York Times best seller has captured media headlines for calling wheat, carbohydrates and sugar "the brain's silent killer".

According to Dr. David Perlmutter's book Grain Brain, all carbs – even the ones that are touted as healthy like whole grains – can cause everything from dementia, ADHD and anxiety to chronic headaches and depression.

In fact, the Florida-based neurologist goes so far as to claim that the human requirement for dietary carbs is "none – none whatsoever".

It's a theory that goes beyond simply advocating a low-carb diet for weight loss, or a gluten-free diet for those who suffer from celiac disease or gastrointestinal discomfort. Instead, the bold claims turn the pillars of the Western diet on their head, vilifying whole grains and wheat as agents of disease.

Perlmutter's take on the best dietary way to optimize brain power? A fat-rich, low-carb diet.

Foods he approves of, for instance, include avocados, olive oil, nuts, cheeses and salmon. Foods high on the Glycemic Index and those that contain gluten should be avoided, including foods that have long been touted as healthy forms of carbs such as wheat, rye, bulgur, barley and oats.

In essence, Perlmutter's prescription for a brain-friendly diet could be described as a variation of the gluten-free diet, the Paleo diet or the Atkins diet. On the last, the doctor tries to differentiate the Grain Brain diet by saying that while the Atkins diet makes no distinction between fatty, grain-fed meats, which are high in inflammatory Omega-6 fats, Perlmutter recommends meat, fowl and fish that are grass-fed, free range or wild caught. – AFP Relaxnews

Posters nudge British workers to take the stairs


Stair use has increased by 29% in buildings with the posters.

WHILE more restaurant chains are putting up calorie counts of their menu items, a British initiative has a novel idea: install posters in offices and public buildings displaying how many calories you'll burn by taking the stairs versus the elevator.

StepJockey, a British government-backed startup that launched this week, bases its principles on the "nudge theory", with posters and a new app that employees can download to calculate how many calories they burn when walking up flights of stairs rather than using elevators or escalators.

In buildings where posters are displayed, stair use increased by 29%, and employees who downloaded the app were five times more likely to walk up stairs, the website reports.

The UK Department of Health and London Mayor Boris Johnson provided funding for the project, The Independent reports.

"It is really important that we all do as much exercise as we can to reduce the risk of preventable illness and lead longer, healthier lives," added Lord Howe, minister for health, according to The Independent. – AFP Relaxnews
