there are no limitations as there are with some other religions, just eat a balanced diet and avoid overly processed foods. generally a vegetarian or vegan diet is not advised here because it weakens you over time.
as for the rest, it depends on what your body needs. for example, many women are naturally low on iron so making sure you get enough is important. ive seen many people here advise men to eat more eggs because it helps in production of testosterone. my overall point being, focus on your health and your needs
