A diet is considered vegetable-rich if
Culinary Vegetables form a significant quantity of the diet, even if the diet includes periods such as individual meals, entire days or even weeks (e.g. a hygienic water fast) which are not vegetable-rich.
Consider it as a guideline that Culinary Vegetables form at least 25% of the weight of total food consumed, averaged over a period of at least a month.
Consumption of Culinary Vegetables on individual days may vary widely, from perhaps 0% to 60% of the volume of total food consumed.
Each bite of Culinary Vegetables contains more minerals than fruit, and can help ensure sufficient dietary mineral intake. To get more minerals and less calories, eat more Culinary Vegetables.
