NutriProfile is based on a food frequency questionnaire which asks a number of simple questions on the amount and frequency of the food you eat to determine your dietary intake.
The most accurate way to analyse your diet is a 7-day weighed food intake, where each individual item of food you eat is weighed and evaluated over seven day period. This is clearly a very impractical and inconvenient way for most of us to analyse our nutrition.
To ensure its accuracy the food frequency questionnaire used in NutriProfile has been scientifically validated against 7-day weighed food intake records in 722 adults. This means the results from the food frequency questionnaire were compared against the more detailed 7-day weighed food intake. The results of this validation, (which are quite technical) are available through the link below for those with a special interest in this subject.
What they mean is that NutriProfile is an accurate and convenient way to analyse your nutrition, without having to weigh and record every single thing you eat for a week!
