We do tend to err on – if something is good for us, then more of that something is going to be even better. It makes logical sense when viewed through the lens of our general world-view.

But, just as in the case for consuming fruits, more, is not better. We have evolved to make the best use of micro-nutrients in portions sizes that our ancestors would have had access to. There is every chance fruits will have been in abundance at certain times of year but not year round as it is now.

Modern human biological evolution to this point – 2014 – has taken around 150,000 years. Modern supermarket, fruit-all-year-round, access is a less than fifty year affair. Clearly our evolution has not had time to be moved on to a point were massive consumption of micro-nutrients is necessary or beneficial, in fact it will probably never be so.

So as with most things human, past evolution plays the biggest part on what we should consume today, further, our past dictates our need and use of consumed foods – bodily homeostasis and physical movement.

Eat a balanced moderate portioned diet and engage in some form of physical activity on most days of the week. It’s what you’ve evolved to do.


This from the BBC News:

New research backs the five-a-day target for fruit and vegetables, but suggests eating more may have no added benefits.

An analysis of 16 worldwide studies suggested that for every portion of fruit and vegetables consumed, there was a lower risk of premature death.

But after five portions a day, there was no further impact, researchers report in The BMJ.
