Associating product content dimensions with products for at least two purchases, where the product content dimensions include quantitative or qualitative values of any of nutrients, calories, ingredients, chemicals, and combinations thereof. Generating a cumulative set of data points for a given product content dimension over a period of time or set of purchases. Fitting the data to trend equations where slopes can be used to determine consumption rates for a given member over a period of time or a set of purchases.
