I’ve always been under the impression…
i would guess maybe because they have been marketed as healthy snacks (hell they are low fat - rolling eyes). food that is actually healthy is not directly marketed as such advertising would make it ridiculously expensive. producers of processed grain products are able to have large misinformation campains based on misperceptions about what causes people to be overweight.
if you want to eat rice cakes, don’t eat them because they are healthy. they most certainly are not and are devoid of nutrients. eat them because you choose to eat them as part of your diet which should otherwise include lean animal protein, fruits and veggies, and healthy fats. eating them before or after a workout may actually help you somewhat, but there are many better products (Surge) that fit the bill.
there is no such thing as good and evil, but as nutritional choices go, rice cakes are barely above fast food in the hierarchy of optimizing nutrient intake.
