Introduction to Vegetarian and Vegan Diets

Vegetarianism and veganism are popular lifestyle choices centered around the exclusion of animal products from one's diet. While both focus on plant-based eating, there are critical differences:

Vegetarians abstain from meat but may consume dairy, eggs, and other animal-derived products.
Vegans avoid all animal products, including meat, dairy, eggs, and often other by-products like honey and gelatin.

This guide provides a structured introduction to these diets, outlining benefits, nutritional considerations, food choices, and tips for beginners.
