Foods contain the nutrients that your body needs. Different foods have different nutrients for growth and development, immunity, cognitive health, better hair and skin, and serve other purposes. A nutritionist has profound knowledge and wisdom to help you improve your physical and mental health, to live a healthy life and perform better in studies or work. A degree as a nutritionist and/or dietician can land you in prestigious and significant positions in health units, sports organizations, clubs, and other organizations as their in-house nutritionist, work with doctors, and complement treatments with balanced nutrition or practice independently as a consultant nutritionist.
