The world's top 5 food crops (see chart) ALL have high phytate content - and of interest, wheat, corn, rice, barley, sorghum,;oats, rye, and millet provide 56% of the food energy and 50% of the protein consumed on earth (1985 figures).

Of 195,000 species of edible plants, only ~17 species provide 90% of mankind's food supply
Prior to the Agricultural Revolution and man living in settlements, humans existed as non-cereal-eating hunter-gatherers, obtaining calories mostly from wild animal meats, fruits and vegetables (i.e. not from grains) - Furthermore, this drastic dietary change occurred without any significant change to mankind's genetic make-up, and although it can easily provide the bulk of needed daily caloric intake, a cereal-based diet may or may not be wholly beneficial for human physiology:
Several health issues were recognized after the change from hunter-gatherer to cereal-based diets - including:
