The term "Vegetarian" is used to describe the practice of abstaining from eating meat or fish, and sometimes other animal products, especially for health, moral, religious, or environmental reasons.

There are different types of vegetarian diets depending on what foods they include and exclude. All vegetarians do not consume meat products and poultry. Some, however, allow consumption of eggs and dairy. Veganism is a form of a strictly plant-based diet as it excludes consumption and use of all animal products and sources.

Vegetarian diets are regarded as healthier provided they include variety of plant-based whole products, high in nutrients and fibre, low in cholesterol, unhealthy fats, sugar and refined salt. Numerous studies found that a well-planned, unrefined vegetarian diet may significantly lower the risk of various health problems.

Vegetarians avoid not only meat products but also nutritional supplements that contain ingredients derived from meat. Majority of the HealthAid® products are suitable for Vegans and Vegetarians.
