Dedicating hours each day to acquiring, preparing, consuming, and cleaning up for the sake of the latest “good nutrition” fad is not my idea of intelligent behavior.
If “nutritionists” want to be of any use, they need to identify "good" tasty foods which real people can readily acquire and quickly consume with little to no preparation & cleanup time.
If "nutritionists" cannot identify such foods from what is currently available, then they need to work with and pressure the food industry to produce such foods. In other words, accept the reality that normal people live in a real world of limited time and deal with it.
Otherwise we're back to the same old routine of; “If it tastes good, spit it out.”
Italy is full of happy overweight old people in their eighties and nineties. The ones in the country that is. They have low stress cause they are happy and part of an extended family and they drink red wine. It’s not difficult to figure out.
