Veganism isn't healthy by default

Veganism promotes Diabetes, dental diseases and muscle wasting.
I'm not saying a proper, balanced vegan diet can't exist, but 99% of vegan either can't afford it or don't follow such a diet. In fact most vegans diet is incredibly unhealthy carb-fests(fruits and sweet vegetables, and "healthy" nuts/legumes with high carb content).

First carbs ruins teeth, carb-heavy diet will 100% cause caries and cavities even with daily flossing and brushing. The sugar in the salive itself will feed bacteria.

Second, carb heavy diet forces one to store carbs as fat, gaining weight and edging close to diabetes which is fueled by carbs.

Third, muscles need exercise and protein, most vegan consume either too little protein or slack off on exercise(causing weight gain with carbs) making their muscles weak and malnourished.

Fourth, carb-centric diet of most vegans lead to premature aging with Advanced Glycation End-Products(fried/baked sugary foods)."stiffer and more brittle cartilage"

Fifth, carbs directly cause aging with their hormonal/genetic impact.

all carbs ruin teeth

Vegans eat lots of carbs, their saliva is filled with it, their gums and teeth are covered with carb layers. Do you expect bacteria to ignore the all-you-can-eat carb feast?

carbs always cause carries

They do, its bacteria food.

vegans eat more fried food than ghouls do

Vegans eat more sugary food in general, which when baked/fried forms advanced glycation end-products which cause aging of tissues.
