Our food in the Anthropocene

Food has become the leading cause of human mortality

Foley et al. 2011

And food fails the environment

Science based targets create a shared ambition

Diet drives the global burden of disease

2500 calories diet constructed

based on the GBD risk

analysis.

Protective foods are those

that lower risk including

polyunsaturated fatty acids

(PUFA).

Harmful are foods that above

a minimum allowed cause

harm.

Cancer $114,253 $101,743 $12,510 -11%

Musculoskeletal disorders $116,528 $115,916 $612 -1%

Following the GBD recommended diet would have reduced US health expenditure in 2006-2010 by $130 billion per year – a 6% reduction.

Food fails health

Today’s food systems drive environmental harm

The Sixth Extinction:An Unnatural History

Elizabeth Kolbert

“We are deciding, without quite meaning to, which evolutionary pathways will remain open and which will forever be closed. No other creature has ever managed this, and it will, unfortunately, be our most enduring legacy.”

Book Review by Al Gore, New York Times, Feb. 2014
