Fructose from whole fruits and berries is fine, because you'd need to eat a lot of fruit to get unhealthy levels of this sugar.

have you a number (gr) of unhealthy levels of this sugar?

It's very easy to get to 60gr/day of fructose by eating fruits and vegetables. Just by eating 2 apples, 100 grams carrots, salad, and 200gr tomato you get those values.

Here's a bit of ungrounded speculation: someone mentioned a theory in another post that eating fruits started a fat-storing 'program' in the body, the idea being that fruits became ripe in the autumn and we gorged on them before the winter.

What if eating a low calorie high protein diet in the same way initiated a 'winter time program' with various physiological and behavioural changes useful for a cold winter...

If this was the case, the length of time we were in this state each year could vary depending on the seasons and the amount of food people were able to store. Perhaps low carb high protein diet is not the ur-diet, but just a possible diet for some of the time. Maybe the advantages of different diets could be balanced by cycling them?

Also, if it was the case that this was a 'program' humans could naturally go into, it could mean that people are in fact genetically predisposed to different diets. For example, when the inuit moved to a perma-winter situation it would not be necessary for them to evolve from scratch to adapt to this climate. I forget the details of the theory, but there's a way that the expression of genes can be altered to produce changes over a shorter timespan than evolution, for example the increase in people's size over the last few hundred years.

or asians are better off eating seafoods than bison or cattle?

I wonder if anyone knows of studies done on centenarians regarding their diets? I realize genetics + lifestyle + luck plays a big role in reaching 100 years + old, but do they have anything in common regarding what they eat?

Do most 100 + year old people have a lifetime of eating low carb, high fat diets? Or little meat, lots of veggies, etc.? Epidemiological studies on long-lived populations are of some help, but what are the similarities, if any, for those who live 100 + as to their diets?

Jeanne Clement was big on chocolate and olive oil, for instance, but I don't know what her diet looked like otherwise.

low calorie high protein

Of course I meant to say low carb high protein

Well if it is possible that changes are possible on a smaller timescale than evolution then there could be any number of local adaptions. I don't know whether this is actually possible or not. I wish I could remember where I read about it.

Epigenetic inheritance is one way, but what I'm thinking of is something where the genome is in fact changed, but a small change in one gene can rapidly change a whole characteristic i.e. it is relatively easy for a mammal to evolve a slightly longer neck compared to evolving compound eyes or something.

However, now I come to think of it if the ability to live on a low carb high protein diet was part of our inheritance rather than an entirely new change could it not be relatively quick for a population to become more specialised towards this diet? Imagine: a small group of hunter gatherers moves North or suffers a cold spell. The ones who by random chance do less well on a mainly animal diet fail to thrive and are killed or can't compete for mates. The remaining inbreed with each other.

I still don't think there has been anything shown, at least peer-review published, that gluten causes problems for more than ~1% of the population.

I don't eat much wheat, but i usually eat high gluten wheat when i do, since i'm eating for that quality...pizza crust or tortilla shells.
