Patrick Holford is a British nutritionist/nutritional therapist and author. He appears regularly on television and radio in the UK and abroad. He has 36 books in print in 29 languages. His work promotes a wide variety of alternative medical approaches such as orthomolecular medicine, many of which are considered pseudoscientific by mainstream science and medicine. Holford's claims about HIV and autism are not in line with modern medical thought, and have been criticised for putting people in danger and damaging public health.
