Vegetarian diet: How to get the best nutrition
Vegetarian diets continue to increase in popularity. Reasons for following a vegetarian diet are varied but include health benefits, such as reducing your risk of heart disease, diabetes and some cancers.
Yet some vegetarians rely too heavily on processed foods, which can be high in calories, sugar, fat and sodium. And they may not eat enough fruits, vegetables, whole grains and calcium-rich foods, thus missing out on the nutrients they provide.
However, with a little planning a vegetarian diet can meet the needs of people of all ages, including children, teenagers, and pregnant or breast-feeding women. The key is to be aware of your nutritional needs so that you plan a diet that meets them.
Types of vegetarian diets
When people think about a vegetarian diet, they typically think about a diet that doesn't include meat, poultry or fish. But vegetarian diets vary in what foods they include and exclude:
Lacto-vegetarian diets exclude meat, fish, poultry and eggs, as well as foods that contain them. Dairy products, such as milk, cheese, yogurt and butter, are included.
Ovo-vegetarian diets exclude meat, poultry, seafood and dairy products, but allow eggs.
Lacto-ovo vegetarian diets exclude meat, fish and poultry, but allow dairy products and eggs.
Pescatarian diets exclude meat and poultry, dairy, and eggs, but allow fish.
Vegan diets exclude meat, poultry, fish, eggs and dairy products — and foods that contain these products.
Some people follow a semivegetarian diet — also called a flexitarian diet — which is primarily a plant-based diet but includes meat, dairy, eggs, poultry and fish on occasion or in small quantities.
