In my childhood, mothers read up on nutrition and meticulously regulated what their families ate. Call it the pro-vegetable era.
When my own children were little, the word was out that everyone should eat whatever they wanted to because their bodies would tell them what they needed. Call it the anti-vegetable era.
Now we are regularly deluged with studies about people who will live five months longer eating this food or that, mainly vegetables. Call it the neo-vegetable era
On the other hand, there are also several studies which have shown that people who are happy live longer--and I'm happier not eating vegetables. Call it the Fiorella-will-eat-whatever-the-heck-she wants-to era
