Is it normal to eat sensibly, wisely, even sagely?

Through my experiment with fad diets and invented diets I invented a much less picky one: the lacto-beegan diet (with some exceptions), and there has to be exceptions, because upon experience and reflection and testing, I was starving, I couldn't even drink anything (I was thirsty and had to break the rules) or eat anything (I was hungry and ditto), it was that bad. I know most wise and sage people are picky eaters but through their experience they learned to eat almost anything within a 25% range of foods, not 10%, or even 5% (Tom tends to fit the 10% category, some day he'll learn he's going to starve almost to death!), therefore it's a serious problem. And dad thinks all pickiness is a serious problem, I think moderately picky is the best because then you'll eat and drink, I know from the experience of being a lacto-pescetarian, I would eat anything as long as it was no animal foods but fish and dairy, no eggs, and have anything vegetarian, therefore my diet now avoids the following things: wheat, corn, white rice, and darnel, and eggs unless specified below, and any drugs whatsoever if I can help it, even medicinal drugs, I also avoid surgery,
has the following things scarcely: fish, seafood, and shellfish (including eggs from them), sugar, salt, fats and oils, and dairy,
and the following things in moderation: coffee, tea, cocoa, caffeine, alcohol, smoking and tobacco, and that's it, it's simple and much less limited, and I'm glad, it's as varied as lacto-pescetarian, except that in most cases I would be a beegan. Would widening the variety in any way be normal? PS: once a lacto-pescetarian always a lacto-pescetarian, and once an eater of honey always an eater of honey. PSS: I would eat, drink, take and smoke something even if it was unpleasant or disgusting, I don't care any more, I don't even care if it's of very poor quality, it has to be this way, because I was starving, if I was on the street I would have to think about that, as most people don't eat unpleasant foods, which is unwise, think of what the Buddhists eat: accepting food that's unpleasant, and take that as a model.
