Dr Leigh Broadhurst

Dr Leigh BroadhurstDr C. Leigh Broadhurst, University of Maryland, USA, is an analytical and field research geochemist with a wide range of scientific interests, and her research publications span fields from high temperature magmatic simulations to the origin of type-2 diabetes. Dr Broadhurst participates in a cross-disciplinary scientific collaboration that investigates the impact of brain-specific nutrition on the origin of modern human intelligence. A particular area of interest is the role of coastal sites  --  and coastal foods such as shellfish, fish and seabirds  --  on the development of human intelligence and culture, and migration out of Africa. Dr Broadhurst has also been an author, lecturer and consultant to the natural products industry for 20 years, with a special emphasis on long-chain polyunsaturated fatty acids, which are essential for normal infant intellectual development and are found abundantly in many varieties of seafood.


  • Seafood - We Really Did Evolve to Eat It!  Part 1
    The natural food diet is the diet humans evolved on and, when you stray away from that, there are going to be consequences.

    We need long-chain polyunsaturated fatty acids (oils) to construct our brain and retina, in particular arachidonic acid and docosahexaenoic acid (DHA), which is the one that's in the product called fish oil, along with another one called EPA … and, in a coastal environment with seafood, these are abundant.

  • Seafood - We Really Did Evolve to Eat It!  Part 2
    We need the things that seafood provides for us: iodine, selenium, iron, copper, zinc. We need all these things in order to create and maintain both our brain's intellect and visual acuity, and also our metabolism to support that very, very energy expensive brain. It all ties in together.

    You have to have some fish. It was always in your diet and, when you remove it, there are consequences.
