There are currently 6 FOOD SPIRAL®s (Healthy, Diabetes (1,800 Calories = 18 Factors, Carb Counting (15 gm. Carbs = 1 Factor, Low Sodium (2,000 mg. = 20 Factors, Renal = 2,000 mg. Na & K and 1,000 mg. Phosphorus = 20 Factors and Renal Diabetes = 2,000 mg. Na & K and 1,000 mg. Phosphorus = 20 Factors) – each designed for a different dietary challenge. Each Food Spiral® is based on the 3 simple colors of a traffic light. Green Foods are considered “GO” foods. We recommend eating these foods at all meals. Yellow Foods are “CAUTION” foods. We recommend eating these foods less often, or 1 to 2 times a day maximum. Red Foods are “STOP” foods. We recommend eating these foods very seldom, or 3 to 4 times a week maximum. These colors signify how healthy a food is for the FOOD SPIRAL® you are using. Now that we understand the 3 colors, it is time to add the 6 food groups to the FOOD SPIRAL®. Foods on the FOOD SPIRAL® are organized as healthiest to least healthy from top to bottom, left to right, light to dark and large too small.
