A vegetarian diet is a type of diet that excludes meat, fish, and poultry. This includes all types of animal flesh such as beef, pork, chicken, and seafood. Some vegetarians may also choose to avoid other animal products such as dairy and eggs.
Types of Vegetarian Diets
There are several different types of vegetarian diets:
- Lacto-ovo vegetarian: This type of vegetarian includes dairy and egg products in their diet.
- Lacto-vegetarian: A lacto-vegetarian consumes dairy products but avoids eggs.
- Ovo-vegetarian: An ovo-vegetarian consumes eggs but avoids dairy products.
- Vegan: A vegan diet excludes all animal products, including dairy, eggs, and honey.
Health Benefits of a Vegetarian Diet
Following a vegetarian diet can have numerous health benefits. These include:
- Lower risk of heart disease: Studies have shown that vegetarians tend to have lower levels of bad cholesterol and blood pressure, reducing their risk of heart disease.
- Reduced risk of certain cancers: Plant-based diets are high in antioxidants and phytochemicals that may help prevent cancer.
- Better weight management: Vegetarians often consume fewer calories and have a lower body mass index (BMI) compared to non-vegetarians.
