Drinks are organized into the following sub-categories: juices, smoothies, carbonated beverages, energy drinks, sports drinks, and bottled water.
GoodGuide's drink ratings are based on the same methodology used to rate food products, including:
The nutritional value of a drink, as characterized by a standard method of nutrient assessment called the “Ratio of Recommended to Restricted Nutrients” (RRR);
Indicators of whether or not levels of specific nutrients exceed public health guidelines;
The presence of potentially hazardous additives such as certain food colors; and
Indicators of various production practices that influence the quality of a food product.
Health Scoring Methodology
The Ratio of Recommended to Restricted Nutrients (RRR) calculates the ratio of “good” to “bad” nutrients, essentially providing an overall picture of a drink's nutrition profile. For drinks, the list of recommended nutrients includes protein, calcium, iron, vitamin A, vitamin C, and fiber and the list of restricted nutrients includes calories, saturated fat, cholesterol, sugar, and sodium.
