Wonderful Question.
I have to say, our world is getting fatter, and it is not just from overeating!
It is the food it's self.The loads of sugar-butter, just calories galore!!!
You have touched on something, that really should be addressed right now.
Yes, in my opinion any chef right now, should be looking at ''The Menu''
for the coming years.
It is getting too late to eat all those death defying foods any longer.
I wonder how many chef's could sit down, and re-invent the way we eat.
Making it that we can eat yummy food, but less calories.
When I lived in LA,there was a place you could eat and nothing was over I think 700 calories, per meal.
Brilliant idea.
