The guidance provides clear oral health and nutrition advice for the whole population. A special focus is given to the under-5s as intervention in the earliest years is vital for improved outcomes in the short and long term and will positively impact across the life course. A focus is also given to nutritionally vulnerable older people as this group has specific nutritional and oral health needs, and are a priority group emphasised in recent government policy. There are other long-term diseases where further specialist advice would also be needed. Between-meals snack and drink advice is also given and will be a useful reference to enable professionals to give practical, consistent advice to all age groups.
