The so called FOOD PYRAMID

UH! After a Scandinavian 1972 model the US developed their own food pyramid model that showed the food choices and proportions we should eat. They have been trying to improve it since 1992. A newer variation is the Healthy Plate.
I have some problems with this.
Who could eat consciously and in scientific proportions of essentials molecules and by counting building blocks?
Nobody. It's like when we are told don't think about something. In that moment you have already thought about it and it's too late. We get hungry, and before we know it we eat. Sometimes if we listen to our body we eat what it needs such as the first fresh strawberries that still has the flavour of the sun, the seasonal water melon, the fresh peas or the small new potatoes that is so good with parsley. Our body lets us know that it is getting low on some nutrition so please, fill up. Hopefully you listen and respond well.
We are all different. In North America we came from many different countries and culture, only a few years or decades, maybe a hundred years tie us together with our neighbour. We are all people of the same species so why would it matter?
It does matter. Our own survival depends on the survival mechanisms our own ancestors developed, where they had been, how they survived. They passed it on through their genes to many generations and finally to us.
This is what we need to know and listen to. A few hundred years back it was no problem at all in close knit communities. But now?
I can't even advise you to go to your mother because in North America mothers have been part of the convenient, processed food generations. But try to find out where your grandparents and their parents came from and how they lived.
Did they live in Asia and ate fish rice and vegetables but no dairy or beef?
Did they come from Middle Europe and had a lot of pork and potatoes, some basic vegetables, seasonal fruit, apple and nuts all year around?
How did they prepared their meals? Try that!
All millions of species on Earth have survived for hundreds of millions of years by passing on the knowledge, the habits to the new generations. They didn't have to know why they just ate the right stuff and survived.
So if dairy doesn't agree with you maybe you shouldn't have it. If pork is too heavy for you maybe you should eat something else. No fancy meals, or exotic plants that promise magic power because it is the best for the people that has had it for hundreds of years.
As my father used to say, eat modestly and sensibly and it will be fine.
