Abstract: A method and apparatus for allowing the user to simultaneously monitor and modify the intake of specific nutrients in a graphical manner. A booklet is utilized for simultaneously monitoring two independent nutrients so as to ensure that the total amount of intake of the first and second nutrients satisfies the requirements of their respective predetermined values. The booklet includes a chart with a series of vertical and horizontal marks to form a grid with numerical labels along the edges of the grid. The user determines the maximum daily intake of the two nutrients based on specific parameters for the individual. A line is drawn parallel to each axis of the chart to indicate the minimum or maximum daily intake of each nutrient. The intersection of the lines is the starting point for each day, graphically showing the user the allowable quantities for each nutrient. The booklet also includes food listings which supply the user with the necessary values for charting each of the variables.
