What is Big Think?  

We are Big Idea Hunters…

We live in a time of information abundance, which far too many of us see as information overload. With the sum total of human knowledge, past and present, at our fingertips, we’re faced with a crisis of attention: which ideas should we engage with, and why? Big Think is an evolving roadmap to the best thinking on the planet — the ideas that can help you think flexibly and act decisively in a multivariate world.

A word about Big Ideas and Themes — The architecture of Big Think

Big ideas are lenses for envisioning the future. Every article and video on bigthink.com and on our learning platforms is based on an emerging “big idea” that is significant, widely relevant, and actionable. We’re sifting the noise for the questions and insights that have the power to change all of our lives, for decades to come. For example, reverse-engineering is a big idea in that the concept is increasingly useful across multiple disciplines, from education to nanotechnology.

Themes are the seven broad umbrellas under which we organize the hundreds of big ideas that populate Big Think. They include New World Order, Earth and Beyond, 21st Century Living, Going Mental, Extreme Biology, Power and Influence, and Inventing the Future.

A Vegetarian Diet and Its Effect On Your Mood

What is the Big Idea?

Eating meat or fish can make a crab out of you, according to  a study published by Nutrition Journal.

Omnivorous diets are high in arachidonic acid (AA) which changes the brain in a way that affects mood. Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), fats prevalent in fish, are suppose to combat the negative effects of AA. However, the study reported significantly worse moods in fish eaters than vegetarians despite higher intakes of EPA and DHA. This is the first study to examine the impact of a meat and fish diet on an omnivore's mood.

Thirty nine meat-eating participants were assigned to one of three diets. A control group ate meat, fish or poultry daily. A second group ate fish 3-4 times weekly but no meat. A third group ate strictly vegetarian. After two weeks, participants completed a questionnaire to assess their moods. The vegetarian group reduced their EPA, DHA and AA intake and the fish eaters increased their EPA and DHA intakes. The mood were unchanged for the omnivores and fish eaters but the vegetarians showed higher mood scores after two weeks.

What is the Significance?

"Reducing meat, fish, and poultry may improve some domains of short-term mood state in modern omnivores," the report concludes. "Exploring this phenomenon further is warranted, as reductions in dietary meat, fish, and poultry would not only reduce health risks but could benefit the environment as well."

Marion Nestle, nutritionist and NYU professor, argues that a vegetarian diet is indeed healthier. But small amounts of meat doesn't hurt. And in developing countries, "where kids don’t have enough food, a little meat thrown in makes a big nutritional difference."
