Entry Requirements:

To become a nutritionist, you typically need a combination of specific subjects and further education, such as a degree or vocational qualification in nutrition or a related field. Here are the recommended subjects and qualifications that can help you on the path to becoming a nutritionist:

  1. Biology: biology is highly relevant as it provides foundational knowledge of human anatomy, physiology, and the biological processes that relate to nutrition and health.
