Knowing your environment

At fist our ancestors lived in the forests full of greenary.As they scavenged for food, the ability to differentiate its colour among the other colours of nature evolved.

Colour changes in leaves, fruits and vegetables can indicate age or ripeness and even offer a warning that something may be poisonous or rotten.

Today, we use this ancestral instinct at a farmers market or grocery store.

This change in colour also applies when glancing over an aisle of bright bell peppers. Our eyes help us find our favoured ripeness and sweetness. Green peppers, with more chlorophyll, are less sweet. As they turn yellow and red, the peppers become sweeter.
