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.

Relationship Between Diet and Health Remains Unclear

What's the Latest Development?

A recently unearthed study has further complicated the relationships between certain kinds of diets and the risk of contracting heart disease. In the late 60s and early 70s, scientists followed a group of men who substantially reduced their intake of saturated fats. "The men were followed for an average of 39 months, and those on the polyunsaturated-rich diet lowered their cholesterol levels by an average of 13 percent. But they also were more likely to die, and in particular to die of a heart attack, than those who stuck with their usual diet, which consisted of about 15 percent saturated fat."

What's the Big Idea?

While diets high in saturated fats are known to increase cholesterol, exactly how cholesterol influences heart disease remains to be fully understood. Philip Calder, a professor of nutritional immunology at the University of Southampton, in England, says the link between cholesterol and heart disease may not be as strong as we think. "That possibility lends credence to other studies showing that assiduously sticking to a diet rich in fish oils, another heart-healthful fat, doesn't necessarily protect people from heart attacks or strokes; and that those who carry extra pounds, even to the point of being slightly obese, may live longer than people who weigh less."
