Any dietary choices can be irresponsible and unhealthful. To illustrate, here’s a list of some vegan foods:
Alcoholic beverages
Soft drinks and “fruit” drinks
Almost all breads
Pasta
Granola bars
Almost all candy (except milk chocolate)
Sorbet
Potato chips, pretzels, and many snack foods
French fries
There are plenty more vegan items that are packed with calories, sugar, fat, or sodium, and that have little or no nutritional value. Still other choices, such as meat substitutes and frozen meals, are loaded with fillers and preservatives.
Not all vegetarian or vegan foods are created equal, and they’re not all healthful. Just like anyone else, a vegetarian needs to balance food choices and pick the right options. It’s very possible for someone to be a committed vegan or vegetarian, following the letter of the law stridently, yet eat very badly.
