It's just a thought, so I am likely to be wrong in many ways, but would love to hear your opinion!
I wonder if we were perhaps a bit healthier when we had less choice? Before globalisation. There are the positives such as more choice for those with varied dietary requirements, etc, but maybe some down sides too?
Is it even optimal to eat fruit every day as we are advised to? At one time we would have had seasonal options and that would be it. Even a middle class child at one point was excited to find an apple and orange in their xmas stocking, so I imagine it wasn't a constant supply.
Is it realistic, environmentally, to aim to eat so many different varieties of foods every day, or even week? And then there's dental health, if we are eating various fruits per day.
Are we healthier as a culture now that there is more choice? Food availability is always a positive, but I personally ended up cutting down in the past year just to simplify my shopping and produce less waste. I didn't need 8 different veggies (including olives, capers, etc) with my pasta, and have found just a trio of broccoli, spinach and tomato is easier on my gut.
I am no expert on this, far from it, but I do find it interesting. Having so much choice has occasionally put me into a quandary, where so much focus on nutrients and variety often eclipsed the joy of eating. I feel that there's possibly a good deal of decadence involved to even enable us to get in to such a quandary!
