Becoming a Vegetarian

According to the 2010 Dietary Guidelines, vegetarian lifestyles have been associated with improved health outcomes such as lower levels of obesity, a reduced risk of heart disease and lower blood pressure.

Are you thinking of becoming a vegetarian? Here’s what you need to know.

What is a Vegetarian?

According the Academy of Nutrition and Dietetics, vegetarians are classified into the following categories:

  • Strict vegetarian or vegan: A vegetarian diet that excludes all animal products such as meat, poultry, fish, eggs, milk, cheese and other dairy products
  • Lactovegetarian: A vegetarian diet that excludes meat, poultry, fish and eggs, but includes dairy products
  • Lacto-ovovegetarian: A vegetarian diet that excludes meat, poultry and fish, but includes eggs and dairy products. Most vegetarians in the United States fall into this category.
  • Pescatarian: A vegetarian diet that excludes meat and poultry, and includes fish, eggs, and dairy products.
  • Flexitarian: A semi-vegetarian diet with a focus on vegetarian food with occasional meat, poultry, or fish consumption.

No matter which category you may fall into, you’ll still want to include whole grains, fruits, vegetables, nuts, seeds, and legumes into your diet. If you are eating a vegetarian diet, you may need to find other sources for the following nutrients.
