Digestive Intelligence tells the fascinating story of how our digestive systems are really our bodies' second brain and how we think and live our emotions via our stomach. Dr Matveikova explains that the digestive system (equivalent to the size of a village football pitch hiding inside our bellies!) contains more than one million neurons, identical to those in the brain, and is responsible for producing 90% of the body's hormone, serotonin, which makes us feel happy and full of wellbeing. It follows that, if our stomach is 'out of sorts' we feel irritable and lacking in energy; and those feelings block our intellectual productivity, disorientate us and completely change our thought patterns and physical processes. Here is Dr Matveikova s advice on how to nurture our second brain and get both our brains working in powerful and creative harmony.
