Homo sapiens brain size is 20% less than it was 29,000 years ago. IQ is also falling 7% a generation. Mental illness is on the increase. Why?
Why are our brains shrinking?
Today’s guest is Professor Michael Crawford. He discovered that brains are made out of omega-3 DHA in the 1970s. He is the Director of the Institute of Brain Chemistry and Human Nutrition.
At Chelsea & Westminster he has shown that pregnant women lacking omega-3 make a ‘filler fat’ called oleic acid, blood levels of which predict brain developmental and cognitive problems in their babies. His new book The Shrinking Brain explains why humanity is devolving, with dire consequences, unless we take action now to put nutrition and brain health at the top of the agenda.

My guest today is Bob Quinn - a true pioneer of ancient, organic grains. In this rare opportunity to meet with him in his 80th year, en route to Italy, recorded in the car on the way to the airport, we unpack the whole story from the origins of the organic, wholegrain movement in the 80’s, up to now. He explains why it isn't gluten that’s causing so many people to react to wheat (other than coeliacs), what’s really happening, and what needs to happen to our food supply. His hat contains Kamut Khorosan grain - mine is made from our alpacas.
My guest today, Professor Robert Lustig - neuroendocrinologist and Professor Emeritus from the University of California San Francisco (UCSF), world-renowned for unravelling how sugar, fructose and ultra-processed foods degenerate health - proposes that there is one messed up underlying process that almost all contributors to cognitive decline compound. This is an overload of reactive oxygen species (ROS), or oxidants, due to a four step dance that grinds healthy metabolism to a halt. If this is right - and I think it is - this means there are four avenues open to us all to prevent the damping down of energy, both in the brain, but also in the body. Find out how in this podcast.

My guest is Dr Tommy Wood, who is Associate Professor of Neuroscience and Paediatrics at the University of Washington. He also heads research at the Food for the Brain Foundation and brain trains professional athletes including Olympians and Formula 1 racing drivers.
In today’s podcast, my guest is Dr Bill Wilson, a front-line physician who practiced medicine in Minnesota and Massachusetts for over 40 years. Three years ago, Dr Wilson was diagnosed with mild cognitive impairment - often described as pre-dementia. Instead of accepting it as inevitable, he took action. The result? He reversed it. Now, drawing on both his medical background and personal experience, Dr. Wilson has developed a sharp, highly practical focus on neuroscience. In this conversation, he breaks down exactly what helped restore his cognitive function - and, just as importantly, what truly matters for anyone on the slippery slope of cognitive decline. If brain health is something you—or someone you love—are thinking about, this episode is essential listening.
