What dietary advice should I trust?

It is vital that personalised dietary advice comes from trained, qualified professionals. Even medical doctors need to refer patients to registered nutritionists or dietitians who work alongside them, as they themselves are not extensively trained in this area. General dietary advice should come from official health organisations such as the Department of Health, the Irish Nutrition and Dietetic Institute, the Irish Heart Foundation; and global organisations such as the International Osteoporosis Foundation or The World Cancer Research Fund. Advice from such organisations can be trusted as it is delivered from expert panels that assess the totality of up-to-date research and is therefore much more trustworthy and robust than single studies or personal theories proposed by individual practitioners.
