Humans possess intelligence when it comes to selecting a nutritious diet
Studies have shown animals use flavour as a guide to the vitamins and minerals they require. If flavour serves a similar role for humans, then we may be imbuing junk foods such as potato chips and fizzy drinks with a false ‘sheen’ of nutrition by adding flavourings to them. In other words, the food industry may be turning our nutritional wisdom against us, making us eat food we would normally avoid and thus contributing to the obesity epidemic.
