Symbols of addiction
Why do some people have a crazy need for certain food or drink? This series of four articles explores the complex underlying causes of addiction.
The simple consequence was starvation when food was scarce, then overeating whenever excess food was around – and the human body had evolved to cope with this by storing excess food ( energy) as body fat which would get used up during times when the food supply is limited.
So it can be seen that our own genes can potentially lead humans to food addiction, especially if they cannot control their instincts to consume sugary and high- nutrition foods.
In the distant past, these foods provide comfort and relief in a harsh environment and it is probable that they can still invoke the same feelings today – the only problem is that modern shops and supermarkets have an unlimited supply of food all year round and therefore the instinct to overeat does not serve humans quite so well these days.
