Can this be as accurate as recording meals? Everyone's way of eating is unique to them.

Even though Diet ID doesn’t record exactly what each person eats, its power lies in its ability to match a known overall eating pattern to theirs– a pattern whose nutritional details are as close, if not closer, than you might expect. To verify this method, researchers have begun validation studies. Participants have their blood drawn, use Diet ID, and fill out a lengthy Food Frequency Questionnaire (FFQ), which is the “gold standard” dietary assessment tool. Unlike the FFQ, Diet ID’s pre-analyzed nutrient breakdown and HEI score can be predictably mapped to your own health risk in a matter of just seconds. So far, results indicate that Diet ID is at least as good as the FFQ for determining the quality and general nutrient breakdown of a person’s diet.
