Better Brain Health

Chocolate reduces stress. Fish stimulates the brain. Is there any truth to such popular beliefs? The findings of researchers around the world say yes: It appears we really are what we eat. A study in a British prison found that inmates who took vitamin supplements were less prone to violent behavior. And in Germany, a psychologist at the University of Lübeck has shown that social behavior is influenced by the ingredients consumed at breakfast. But what really happens in the brain when we opt for honey instead of jam, and fish rather than sausage? Scientists around the world are trying to find out. Neuro-nutrition is the name of an interdisciplinary research field that investigates the impact of nutrition on brain health. Experiments on rats and flies offer new insight into the effects of our eating habits. When laboratory rats are fed a diet of junk food, the result is not just obesity. The menu also has a direct influence on their memory performance. The role of the intestinal flora has been known for some time, but scientists are currently discovering other relationships. So-called "brain food" for example: The Mediterranean diet that’s based on vegetables and fish is said to provide the best nutrition for small grey cells. Omega-3 fatty acids, which are found in fish, for example, protect the nerve cells and are indispensable for the development of the brain - because the brain is also what it eats!

Heart vs Mind: What Makes Us Human?

The heart is the most symbolic organ of the human body. Throughout history it has been seen as the site of our emotions, the very centre of our being. But modern medicine has come to see the heart as just a pump; a brilliant pump, but nothing more. And we see ourselves as ruled by our heads and not our hearts. In this documentary, filmmaker David Malone asks whether we are right to take this view. He explores the heart's conflicting histories as an emotional symbol and a physical organ, and investigates what the latest science is learning about its structures, its capacities and its role. In the age-old battle of hearts and minds, will these new discoveries alter the balance and allow the heart to reclaim something of its traditional place at the centre of our humanity?
