The Scientific Advisory Committee on Nutrition (SACN) has derived new energy reference values. For most population groups, except for infants and young children, the values have increased. This change reflects the more accurate methods used to assess energy expenditure; the evidence base available to Committee on Medical Aspects of Food Policy was more limited and as a result energy requirements were underestimated for some age groups.
It is important to note that Dietary Reference Values (DRVs) should be used to assess the energy requirements for large groups of people and populations, but should not be applied to individuals due to the large variation in physical activity and energy expenditure observed between people.
Despite SACN’s best efforts to base its recommendations on the most up to date evidence, it should be noted that there is less Doubly-Labelled Water (DLW) data available for infants, younger adults (18 to 30 years) and those aged 80 years.
The Committee hopes that this will be addressed in the future
