The United States Department of Defense (DoD) recognizes that nutrition is critical for the health, readiness, and performance of its service members. To translate complex nutritional science into practical guidance, the military utilizes a unique program called Go for Green® (G4G).
Found primarily in military dining venues, G4G serves as the DoD’s cornerstone nutrition guidance initiative. Its core mission is to make it simple for soldiers, sailors, airmen, marines, and guardians to identify and choose foods and beverages that fuel peak performance and support overall health.
This is achieved through an intuitive “stoplight” labeling system—using Green, Yellow, and Red codes—that provides quick visual cues about the nutritional quality of menu items right at the point of decision.
By making high-performance options more visible and accessible, G4G creates food environments that naturally support the well-being and operational effectiveness of those serving the nation. This initiative represents a significant government effort to embed health promotion directly into the daily lives of military personnel, simplifying nutrition information to empower healthier choices.
Go for Green® (G4G): Fueling the Force
What It Is: Official Definition and Primary Goals
Go for Green® (G4G) is officially defined as a Department of Defense joint-service performance-nutrition program designed to improve the food environments where service members live, work, and train. It employs a standardized stoplight color-coding system—Green, Yellow, and Red—to label foods and beverages, making it quick and easy for personnel to select options that best support their energy needs and performance goals.
The primary aim of G4G is to optimize the “nutritional fitness” of the force. Nutritional fitness is recognized as a crucial component of the DoD’s Total Force Fitness framework, a holistic approach emphasizing the interconnectedness of various wellness domains (physical, mental, social, spiritual, etc.) for overall health, performance, and readiness.
G4G advances nutritional fitness by increasing the access, availability, and knowledge of high-performance food and drink options, specifically those coded Green. The ultimate goal is to “make the healthy choice the easy choice” within military dining settings.
This focus on modifying the environment itself, rather than solely relying on individual education, is a key aspect of the program’s strategy. By ensuring high-performance options are readily available and easily identifiable, G4G actively shapes the dining landscape to nudge service members towards choices that enhance their capabilities.
The program explicitly links nutritional choices to mission success. The language used in official descriptions consistently connects G4G to optimizing “performance, readiness, and health” and enabling service members to perform optimally “under the most rigorous conditions”. This framing underscores that G4G is viewed not merely as a wellness benefit but as a strategic tool essential for maintaining an effective and resilient fighting force.
The Journey of G4G: From Concept to Current Program
The Go for Green® program seen today is the result of significant evolution and refinement over more than a decade. Its origins trace back to 2008 with the U.S. Army’s “Soldier Fueling Initiative,” which first introduced the concept of using stoplight colors to label foods in dining facilities. Recognizing the value of this approach, the program was subsequently adopted by all branches of the military.
Since its inception, G4G has undergone several major updates, reflecting a growing understanding of effective nutrition intervention strategies:
G4G 1.0 (Started 2008): The initial version focused primarily on the core concept of stoplight labeling using standardized food cards and informational posters.
G4G 1.5 (Implemented 2015–2016): This iteration added more structure, introducing menu coding goals (targets for the number of Green/Yellow/Red items), basic food placement strategies (choice architecture), and standardized initial staff training.
G4G 2.0 (Implemented 2017): The current version represents a significant leap forward, transforming G4G into a “more robust, multicomponent nutrition program”. Key enhancements include ongoing staff training, active promotion of Green-coded items, a formal marketing plan, and clearly defined program requirements for consistent implementation across facilities. G4G 2.0 also saw the development of crucial evaluation tools, like the Program Fidelity Assessment (PFA), designed to measure how well facilities are adhering to program standards—a first in G4G’s history.
This evolution from simple labeling to a comprehensive, multi-component program mirrors broader trends in public health and nutrition science. It demonstrates a recognition within the DoD that simply providing information (labels) is often insufficient to drive significant behavioral change.
G4G 2.0 incorporates strategies that actively shape the food environment (placement, menu standards) and provide ongoing support (training, marketing), reflecting a more sophisticated approach to health promotion. The introduction of fidelity assessments also signals a commitment to evidence-based practice and continuous quality improvement, ensuring the program is implemented effectively and consistently.
The G4G program is formally governed by the DoD Nutrition Committee, and major revisions, like those leading to G4G 2.0, were approved by the Joint Subsistence Policy Board. Its implementation is supported by key military policies, including DoD Manual 1338.10 (DoD Food Service Program) and the joint-service regulation AR 40–25/OPNAVINST 10110.1/MCO 10110.49/AFI 44–141 (Nutrition and Menu Standards for Human Performance Optimization).
Part of a Bigger Picture: G4G and DoD Nutrition Standards
Go for Green® does not exist in isolation; it serves as a practical application tool designed to help service members meet the broader, comprehensive nutrition standards established by the Department of Defense. These overarching standards, detailed in regulations like AR 40-25 and its sister-service equivalents, aim to optimize human performance across the force. Resources like the Warfighter Nutrition Guide provide detailed, science-based nutritional strategies for military personnel operating under demanding conditions.
G4G functions as the vital link between these complex nutritional guidelines and the everyday food choices made by service members. The G4G coding criteria, which determine whether a food is labeled Green, Yellow, or Red, are carefully developed based on scientific literature, input from DoD nutrition professionals, and federal dietary guidelines. These criteria are reviewed periodically (at least every five years) to ensure they align with current scientific evidence and food product availability.
Essentially, G4G acts as a user-friendly interface for complex nutritional policy. Instead of requiring each service member to memorize detailed nutrient requirements or analyze nutrition facts panels for every meal component, G4G translates the underlying science and standards into a simple, visual code displayed directly on food cards in the dining facility. This makes it significantly easier for personnel to identify and select foods that align with DoD performance nutrition goals at the moment they are making their choices.
While G4G effectively highlights nutrient-dense, performance-enhancing foods, it is not designed as a specific diet plan, such as a low-calorie or macronutrient-restricted diet. Service members seeking personalized nutrition recommendations for specific goals (like weight management or precise macronutrient targets) are advised to consult with a registered dietitian. G4G complements general healthy eating principles, like those promoted by MyPlate, by providing a tailored, performance-focused lens within the military food environment.
Decoding the Colors: How G4G Guides Food Choices
The G4G Stoplight: Green, Yellow, Red Explained
The core of the Go for Green® program is its simple, intuitive stoplight color-coding system. Each color provides immediate guidance on the nutritional quality and performance impact of a food or beverage item:
Green (High-Performance Fuel): Items labeled Green are the most nutrient-dense choices, providing the optimal fuel for performance and health. Service members are encouraged to choose Green-coded foods and drinks often, making them the foundation of their meals whenever possible. The visual cue for Green items is typically a checkmark symbol on the food card.
Yellow (Moderate-Performance Fuel): Yellow-coded items offer moderate nutritional value. While acceptable choices, they are less optimal than Green options. These foods and drinks should be consumed occasionally. The visual cue for Yellow items is often a caution symbol.
Red (Low-Performance Fuel): Foods and beverages labeled Red are the least nutritionally beneficial and may potentially hinder performance, recovery, or health goals if consumed frequently. These items are typically higher in calories, unhealthy fats, added sugars, and/or sodium, and lower in essential nutrients. Service members are advised to consume Red-coded items rarely or in limited portions. The visual cue for Red items is usually a stop sign symbol.
This clear, visual system is designed to cut through nutritional complexity and allow for rapid decision-making in busy dining facility lines. The stoplight analogy is easy to grasp: Green means “go” (eat often), Yellow means “caution” (eat sometimes), and Red means “stop and think” (eat rarely).
What Makes a Food Green, Yellow, or Red?
The assignment of a Green, Yellow, or Red code to a menu item is not arbitrary. It follows a standardized process using specific G4G Criteria and a detailed G4G Coding Algorithm, applied by trained and certified G4G coders to ensure consistency and accuracy across all services and installations. While the full algorithm involves a point system based on multiple nutritional factors, the core principles guiding the classification can be understood through several key considerations:
Preparation Method: How a food is cooked significantly impacts its nutritional profile. Items prepared using deep-frying methods are automatically classified as Red. Healthier methods like baking, grilling, steaming, broiling, or roasting are favored.
Presence of Harmful Ingredients: Certain ingredients trigger an automatic Red classification due to their negative health implications. These include trans fats (listed as “partially hydrogenated oils” on ingredient labels) and added monosodium glutamate (MSG).
Fat Quality and Quantity: The algorithm assesses both the percentage of calories derived from saturated fat and the percentage from total fat. Lower amounts generally score better. However, there are exceptions for foods rich in heart-healthy unsaturated fats, such as salmon or certain oil-based dressings, which may score well for total fat even if the percentage is slightly higher, provided the saturated fat remains low.
Fiber Content: Higher fiber content is rewarded in the scoring system. Foods rich in dietary fiber, like whole grains, fruits, vegetables, and legumes, generally receive more points.
Sugar Content: The amount of total sugar per serving is evaluated, with lower sugar content scoring more points. This helps limit intake of added sugars, which provide calories but few essential nutrients.
Level of Processing: The algorithm favors foods made primarily from whole-food ingredients (e.g., fresh/frozen produce, unprocessed meats, whole grains, plain dairy). Items that are heavily processed or contain highly refined ingredients generally score lower, as processing can strip nutrients and often involves adding unhealthy fats, sugars, and sodium.
Beverages are coded using similar principles, focusing on factors like added sugar content, use of artificial ingredients, saturated fat (in creamy drinks), and the presence of beneficial nutrients like vitamins and minerals.
These criteria reflect contemporary nutrition science priorities, emphasizing whole foods, fiber, and healthy fats while discouraging excessive intake of saturated and trans fats, added sugars, sodium, and highly processed ingredients. The automatic Red classifications for specific preparation methods and ingredients send a clear signal about detrimental food characteristics. The multi-factor point system allows for a more nuanced assessment of overall nutritional quality compared to relying on single nutrient cut-offs (except for the automatic Red flags).
Examples: What You Might See in Each Category
To make the G4G system more concrete, here are examples of common food items typically found within each color category in military dining facilities. Note that specific preparation methods can influence the final code.
| Category (Color/Symbol) | Performance Level | General Characteristics | Common Examples |
|---|---|---|---|
| Green (✓ Checkmark) | High-Performance Fuel | Nutrient-dense, less processed, lower in unhealthy fats/sugar/sodium, often higher fiber. | Baked or grilled chicken/fish, lean meats, eggs, tofu, beans/lentils, whole grains (oatmeal, brown rice, quinoa), fresh/frozen fruits & vegetables, salads, water, skim/1% milk, plain yogurt, unsweetened tea/coffee. |
| Yellow (⚠️ Caution) | Moderate-Performance Fuel | Moderately processed, average nutrient density, may have some added sugar/fat/sodium. | Leaner processed meats (some deli meats), white pasta/rice, waffles/pancakes, low-fat flavored yogurt, granola, pretzels, 100% fruit juice, sports drinks. |
| Red (🛑 Stop Sign) | Low-Performance Fuel | Highly processed, high in calories, unhealthy fats, added sugars, and/or sodium, low fiber. | Deep-fried foods (french fries, fried chicken), fatty processed meats (sausage, bacon*), pastries, cookies, cake, sugary cereals, candy, chips, creamy sauces/dressings, soda, sweetened tea/coffee drinks, energy drinks. |
*Note: Some facilities may use oven-frying techniques for items like bacon, potentially affecting their code compared to deep-fried versions.
This table provides a quick reference for understanding the types of foods associated with each G4G color code, helping to visualize how the system guides choices toward more performance-oriented options.
Beyond the Color: Understanding Sodium Labels
In addition to the primary Green, Yellow, or Red color code indicating overall nutritional quality, G4G food cards feature a separate symbol to provide specific information about sodium content. This is represented by a saltshaker icon, often with varying levels indicated, corresponding to:
- Low Sodium
- Moderate Sodium
- High Sodium
The specific thresholds (measured in milligrams, mg) that define these categories vary depending on the type of food item being assessed (e.g., an entrée will have different thresholds than a side dish, soup, or condiment). A detailed sodium table within the G4G coding guidelines specifies these thresholds for different food categories. Notably, certain items like plain fruits and most beverages are typically not assigned a sodium code.
The decision to include a distinct sodium label alongside the main color code highlights the particular importance placed on sodium management within the military context. While sodium content does factor into the overall Green/Yellow/Red determination, its separate labeling allows service members to make more informed choices specifically related to their sodium intake.
This may be particularly relevant due to sodium’s role in hydration, blood pressure regulation, and performance, especially under conditions of heat stress or intense physical exertion often encountered in military operations. This dual system provides a more comprehensive nutritional picture, enabling personnel to manage both overall food quality (color code) and sodium intake (saltshaker code) effectively. Ensuring the accuracy of both codes is emphasized as crucial for building diner trust and facilitating informed choices.
Finding G4G: Where Service Members See the Program
Environments: From Dining Halls to Vending Machines
The Go for Green® program is most prominently implemented in appropriated-fund military Dining Facilities (DFACs – the term commonly used by the Army and Air Force) and Galleys (the term used by the Navy and Coast Guard). These are the primary locations where service members, particularly enlisted personnel and those living in barracks or on ships, consume their meals.
However, the reach of G4G extends beyond these traditional dining halls. Recognizing that service members obtain food from various sources throughout their day, the DoD aims to create a consistently supportive food environment across installations. Therefore, G4G labeling principles and signage are increasingly being applied in other food venues, including:
- Snack bars and cafés
- Grab-and-go kiosks and fueling stations
- Mini-markets and convenience stores (Exchanges or NEX/MCX locations)
- Commissaries (military grocery stores), sometimes using related programs like the “Thumbs Up Nutrition Guide”
- Vending machines, often featuring healthier “FitPick” options aligned with G4G principles
- Military Treatment Facilities (MTFs)
The program also encourages service members to apply G4G principles “Anywhere!” – providing resources and guidance for making healthier choices when eating outside of designated G4G-labeled venues, dining out in the local community, or cooking at home.
This strategy of extending G4G beyond the main dining halls aims for environmental saturation. By encountering consistent nutritional cues across multiple food access points on an installation—from the main meal line to a quick snack from a vending machine—service members receive reinforced messages about healthy eating.
This pervasive approach makes healthier choices more convenient and visible throughout the service member’s daily routine, maximizing the program’s potential impact on overall dietary habits. The goal is to embed performance nutrition support into the fabric of the military environment, wherever personnel live, work, and train.
Visual Identity: Food Cards, Signage, and Strategic Placement
Go for Green® relies on a clear and consistent visual identity to communicate nutritional information effectively at the point of decision. The key visual elements include:
Standardized Food Cards: These are the cornerstone of the G4G visual system. Placed at or near each menu item, these cards display essential information: the food or drink name, the G4G color code symbol (Green checkmark, Yellow caution sign, or Red stop sign), the sodium code symbol (saltshaker indicating Low, Moderate, or High), and the official G4G logo.
Using standardized, approved cards is crucial for program integrity and diner recognition; facilities are advised against creating their own versions. Accuracy in matching the card to the correct menu item and its corresponding code is heavily emphasized to build diner trust.
Signage and Promotional Materials: Beyond the individual item cards, facilities use posters, table tents, and menu boards to explain the G4G program and promote healthier options. Special signs, such as “Featured Meal” signs, are used to highlight specific Green-coded meals or combinations offered that day. Marketing and education materials are a required component of G4G 2.0.
Strategic Placement (Choice Architecture): G4G 2.0 moves beyond simply labeling foods; it actively incorporates principles of choice architecture to make healthier options easier to select. This involves deliberate food placement strategies within the dining facility serving lines. Common techniques include:
- Placing Green-coded items at the beginning of the serving line
- Positioning Green options at eye level on shelves or displays
- Displaying healthier items more prominently or in front of less-nutritious (Red) options
An example layout might place steamed vegetables and grilled chicken before mashed potatoes and fried fish.
Menu Design and Goals: G4G 2.0 also includes specific “Menu Coding Goals” that require dining facilities to offer a minimum percentage of Green-coded items for various meal components (like entrées, starches, vegetables) at each meal, while limiting the number of Red-coded options. The overarching aim is to “shift menu design away from an overabundance of Red-coded items towards more Green-coded items,” ensuring that healthy choices are consistently available.
The integration of these visual cues and placement strategies demonstrates that G4G 2.0 leverages insights from behavioral science. By manipulating the environment—making the Green choices more visible, accessible, and convenient—the program aims to “nudge” service members towards healthier selections.
This approach recognizes that subtle environmental factors can significantly influence behavior, sometimes even more powerfully than conscious deliberation based on nutritional information alone. It’s about making the high-performance choice the path of least resistance.
The Impact of Eating Green: Benefits for Service Members
Boosting Nutritional Fitness and Meal Quality
The implementation of Go for Green®, particularly the more comprehensive G4G 2.0 version, has demonstrated measurable success in improving the nutritional quality of meals consumed by service members. The program directly targets the enhancement of “nutritional fitness” by empowering personnel to identify and select nutrient-dense foods more easily.
Formal evaluations of G4G 2.0 have provided evidence of its effectiveness. One key study conducted at military dining facilities measured meal quality using the Healthy Eating Index (HEI), a standardized score reflecting adherence to dietary guidelines. The results showed a statistically significant improvement in average HEI scores after G4G 2.0 was implemented, rising from a median score of 55.0 (out of 100) before the intervention to 64.1 after. This indicates that diners were making objectively healthier choices following the program’s introduction.
Specific dietary improvements observed in the study included an increased selection of whole grains, seafood, and plant-based proteins, along with a reduction in the consumption of refined grains. Furthermore, diners’ perceptions shifted positively; significantly more participants agreed that the main dishes offered were nutritious and performance-based after the G4G 2.0 rollout compared to before. There was also a significant increase in the percentage of diners reporting that they used the color-coded labels to help them choose performance-enhancing foods.
These findings validate the multi-component approach of G4G 2.0. The combination of clear labeling, increased availability of Green options (driven by menu coding goals), and strategic placement appears effective in creating a “supportive food environment” that demonstrably shifts dietary patterns towards healthier profiles. It shows the program can successfully bridge the gap between nutritional recommendations and actual food choices on the plate.
Enhancing Performance, Readiness, and Recovery
The benefits of improved nutritional choices facilitated by G4G extend directly to critical military outcomes: performance, readiness, and recovery. Official sources consistently emphasize that good nutrition provides the essential fuel needed for service members to operate effectively in demanding roles.
Choosing Green-coded, high-performance foods and drinks is linked to tangible enhancements in both physical and cognitive capabilities. These nutrient-rich options can lead to improved physical fitness, better mood regulation, and increased endurance. Optimal fueling enables service members to perform better across multiple domains – “cognitively, mentally, psychologically, and physically”. This holistic view is central to the DoD’s Total Force Fitness concept, which recognizes that readiness depends on more than just physical strength.
Beyond immediate performance, a diet rich in high-quality nutrients, as promoted by G4G, plays a crucial role in recovery. Consuming nutrient-dense meals supports more productive workouts and facilitates faster recovery from the physical and mental stresses inherent in military training and operations, as well as recovery from injuries. This enhanced resilience contributes directly to maintaining individual and unit readiness.
The program’s focus on “nutritional fitness” is therefore intrinsically linked to the military’s core mission. By helping service members make food choices that support optimal functioning and faster recovery, G4G contributes to sustaining a healthy, resilient, and operationally ready force capable of meeting any challenge. The benefits are viewed comprehensively, encompassing not just physical output but also mental acuity, psychological well-being, and the ability to bounce back from stress, all of which are vital for mission success.
Addressing Challenges: Cost and Knowledge Gaps
While evaluations demonstrate G4G 2.0’s effectiveness in improving meal quality and diner satisfaction, they also highlight areas that present ongoing challenges or require further attention.
One practical consideration identified in a study evaluating G4G 2.0 implementation was cost. The research found that the intervention, which emphasized more fresh ingredients and potentially higher-quality proteins, resulted in an average increase of 11% in the cost per plate. While improved nutrition offers long-term value, this immediate cost increase could pose a barrier to widespread, sustainable implementation across all facilities, particularly within fixed budgets. Future efforts may need to explore strategies for optimizing menus to achieve nutritional goals while managing costs effectively.
Another area noted for improvement is nutritional knowledge. The same study found that, despite the positive changes in eating behaviors, the overall nutrition knowledge scores among both diners and foodservice staff remained relatively low (below 60% accuracy on a questionnaire) even after the G4G 2.0 program was implemented. However, the study did observe that individuals who were exposed to the G4G program and received at least one hour of nutrition education demonstrated a greater proportion of correct responses to knowledge questions.
This suggests that while the environmental changes introduced by G4G (labeling, placement, availability) are effective in nudging healthier behaviors and improving meal quality, they may not automatically translate into a deep understanding of nutrition principles among the target audience. Achieving significant improvements in nutrition knowledge likely requires dedicated, ongoing, and potentially more engaging educational strategies to complement the environmental interventions of G4G.
It underscores that influencing behavior and enhancing knowledge are related but distinct goals, both requiring tailored approaches for optimal program success. Continued research is suggested to evaluate facilitators and barriers related to availability, access, cost, consumption, and outcomes related to health and performance.

Understanding G4G and Military Nutrition: Key Concepts & FAQs
Key Concepts Explained
To fully grasp Go for Green® and its context, understanding these key terms is helpful:
Performance Nutrition: This goes beyond general healthy eating. It’s specifically defined as consuming “high-quality nutrition — the appropriate amount at the right time for the right event” to optimize performance. It focuses on fueling the body to function at its peak cognitively, mentally, psychologically, and physically, especially under demanding military conditions. G4G is a primary tool supporting performance nutrition in the military.
Nutritional Fitness: Considered a core component of overall military readiness, nutritional fitness refers to the state achieved by optimizing nutrient intake to enhance health, boost performance, and ensure mission preparedness. Go for Green® directly aims to improve the nutritional fitness of service members.
Nutrient Density: This refers to the concentration of beneficial nutrients (vitamins, minerals, fiber, lean protein) within a food relative to its calorie content. Green-coded foods are typically high in nutrient density, providing substantial nutritional value per calorie, whereas Red-coded foods are often low in nutrient density (high in calories, low in essential nutrients).
Total Force Fitness (TFF): This is the DoD’s holistic framework for well-being and resilience. It recognizes that optimal performance depends on multiple interconnected domains, including physical health, mental acuity, spiritual well-being, social connections, and nutritional fitness. G4G supports the nutritional fitness domain within this larger TFF model.
Choice Architecture: This concept, borrowed from behavioral science, involves intentionally designing environments to make certain choices easier or more likely than others, without restricting options entirely. G4G 2.0 utilizes choice architecture through strategies like placing Green items prominently at the start of serving lines or at eye level. It’s about “nudging” healthier choices by making them more convenient and visible.
Program Fidelity: This term refers to how closely a program is implemented according to its original design and established requirements. High fidelity means the program is being delivered as intended. For G4G, program fidelity is assessed using the Program Fidelity Assessment (PFA) tool to ensure consistency and quality across different dining facilities.
Frequently Asked Questions (FAQs) about G4G
Here are answers to some common questions about the Go for Green® program:
What exactly IS Go for Green?
Go for Green® (G4G) is the Department of Defense’s standard system for helping service members choose healthy foods in military dining facilities. It uses simple Green, Yellow, and Red color codes, like a traffic light, to show the nutritional quality of menu items. Green foods are high-performance fuel (eat often), Yellow are moderate (eat sometimes), and Red are low-performance (eat rarely).
Who uses Go for Green?
The program is used across all branches of the U.S. military (Army, Navy, Air Force, Marines, Space Force, Coast Guard). It’s primarily implemented in military dining facilities (DFACs) and galleys.
How do they decide if a food is Green, Yellow, or Red?
Trained coders use a standardized G4G Coding Algorithm based on specific nutritional criteria. Key factors include preparation method (deep-fried is Red), presence of trans fat or MSG (also Red), saturated and total fat content, fiber, sugar, and the level of processing (whole foods are favored).
Is G4G a diet plan?
No, G4G is not a specific diet plan for weight loss or hitting exact macronutrient targets. It’s a guidance system to help service members easily identify more nutritious, performance-enhancing food options within the dining facility environment. For personalized diet plans, consulting a registered dietitian is recommended.
Where can I find G4G labels?
You’ll primarily see G4G labels on food cards in military dining facilities (DFACs/galleys). However, the program is expanding, so you might also see G4G-aligned labeling or options in other places on base like grab-and-go spots, snack bars, mini-markets, and even on some vending machines.
Does G4G actually work?
Yes, studies have shown that implementing G4G 2.0 leads to measurable improvements in the nutritional quality of meals chosen by service members, as indicated by higher Healthy Eating Index scores. Diners also report using the labels to make performance-focused choices more often after the program is implemented.
Can families or civilians use G4G principles?
Absolutely. While the labels are specific to military food venues, the underlying principles—choosing more whole foods, fruits, vegetables, lean proteins, and whole grains, while limiting processed foods, unhealthy fats, and added sugars—are beneficial for everyone. Many G4G resources, like recipes on the HPRC website, are publicly accessible and can be used by anyone interested in healthier eating.
What’s the difference between G4G 1.0 and G4G 2.0?
G4G 2.0 (the current version, implemented starting 2017) is much more comprehensive than the original G4G 1.0 (from 2008). While G4G 1.0 focused mainly on labels and posters, G4G 2.0 includes strategic food placement (“choice architecture”), specific menu goals to increase Green options, enhanced staff training, marketing components, and defined program requirements with fidelity assessments.
What does the saltshaker symbol mean?
In addition to the Green/Yellow/Red color code, food cards have a saltshaker symbol that indicates the relative sodium content of the item: Low, Moderate, or High. This helps service members manage their sodium intake specifically.
