Seriously, do we actually NEED all these different ones? There must surely be enough vitamins and minerals in a smaller number? Only a limited range is available in season and some of us are conscious of air miles used to transport exotic fruits, for example. ( Sorry, I know this was intended as a light hearted thread).
Isn't it to do with the microbiome which improves digestion, the immune systems and metabolism. Different plants have different microbiomes.
I was surprise to hear on the Royal Institution Christmas Lectures that Chris Van Tulleken's microbiome will have more in common with his pet cat's microbiome than with his twin brother Xander's ... because the cat drinks from the kitchen tap!
