We need to define what do you mean by "Superior". In terms of morality? This begs the question, "What is morality?". Is it subjective? If yes, then no. If no, then we need to define the tenants of morality. Are the tenants of morality subjective or objectives? If subjective, then even though there exists an objective morality out there, we all however, by the limits of our being, will be following the subjective tenants of morality. Therefore the notion of 'Superiority' will be in question.
Now, allow me to offer a Dharmic perspective. It works on the philosophy of Ahinsa - the minimum harm path.
This accepts the fact that life is suffering and dependent on violence. Therefore, our goal should be live a life in a manner that minimizes harm to ourselves and others. Depending on this notion, different actions are hierarchically put in terms of their decreasing harm.
In terms of food choice, here it is:
Eating humans < Eating animals < Eating plants < Eating plant fruits < Drinking water < Eating and drinking nothing.
Basically it is less harmful for you and the environment if you eat nothing than drink water than eat fruits of plants than eat plants than eat animals than eat humans. So we should eat nothing and die? Well there is where the Dharmic traditions say, "The greatest harm or violence is one that is done upon oneself". So, if you think by not eating you are harming yourself then drink water. If you think by not eating you are harming yourself then eat fruits and so on. But if you can survive on little but just cannot help but control your gluttony then that's called morally wrong way to live or Adharmic way to live.
This means if your body needs meat for one reason or another for betterment of health, by all means go ahead and eat meat. In the end it all depends on what your body needs to remain healthy should be deciding what you eat; rather than your taste buds and some rigid ideology.
PS.
This is not vegan philosophy. It's the philosophy of Ahinsa as described in Hinduism, Buddhism, and Jainism.
