Understanding the 'Basic 7'
Released by the U.S. Department of Agriculture (USDA) during World War II, the 'Basic 7' food guide was a pivotal moment in American nutritional history. Designed to ensure a healthy and balanced diet despite widespread rationing, this guide outlined seven specific food groups for daily consumption. The emphasis was on a variety of foods to ensure nutrient adequacy, particularly focusing on vitamins that were well understood at the time. The seven groups were:
- Group One: Green and Yellow Vegetables. This group highlighted the importance of Vitamin A, which was thought to improve eyesight, a concern for both soldiers and industrial workers. Foods included dark, leafy greens and yellow vegetables, served raw, cooked, or canned.
- Group Two: Oranges, Tomatoes, Grapefruit. A dedicated group for Vitamin C sources, this category also included raw cabbage and salad greens to prevent scurvy. These items were available and not as heavily rationed as meat or sugar.
- Group Three: Potatoes and Other Vegetables and Fruit. A broad category covering a wide range of produce, this group supplied fiber and additional carbohydrates. Potatoes were specifically promoted as an alternative to bread, which was more heavily rationed.
- Group Four: Milk and Milk Products. Recognized for its balance of protein, fat, and sugar, this group also emphasized calcium. Items like fluid milk, evaporated milk, and cheese were included.
- Group Five: Meat, Poultry, Fish, or Eggs. The primary protein source, this group was heavily impacted by rationing, leading to recommendations for substitutes. Alternate sources like dried beans, peas, nuts, and peanut butter were also listed here.
- Group Six: Bread, Flour, and Cereals. Recognizing that refined white flour lacked nutrients, this group promoted whole-grain, enriched, or restored bread, flour, and cereals. This was a shift from earlier nutritional advice and led to enriched products becoming more common.
- Group Seven: Butter and Fortified Margarine. Surprisingly, butter had its own food group. This was to ensure adequate intake of Vitamin A and to offer a fat source that provided satiety, especially during rationing when other fats were limited.
The Historical Context of the Basic 7
The 1943 guide was a direct response to wartime conditions. Rationing and food shortages meant that a simple, clear guide was necessary to help Americans maintain their health and productivity on the homefront. Unlike later guidelines, the focus was less on portion sizes and more on variety across the specific categories to ensure the intake of key nutrients like Vitamin A and C, which were seen as crucial for general wellness. It was a tool for national efficiency as much as public health, ensuring that the workforce and military personnel remained fit.
The separation of fruits and vegetables into three distinct groups is a notable characteristic of this guide. This detailed categorization shows the specific focus on ensuring adequate vitamin intake from different plant sources, a more granular approach than simply grouping them together as in later dietary guides. Likewise, the inclusion of butter and fortified margarine as a separate group underscores the importance placed on specific fortified nutrients and fat for satiety during a period of scarcity.
Comparison: 1943 'Basic 7' vs. Modern Guidelines
| Feature | 1943 'Basic 7' Guide | Modern Dietary Guidelines (e.g., MyPlate) | 
|---|---|---|
| Number of Groups | 7 | 5 (Fruits, Vegetables, Grains, Protein Foods, Dairy) | 
| Focus | Ensuring nutrient adequacy amid food rationing | Emphasis on proportionality, overall health, and chronic disease prevention | 
| Fruits/Vegetables | Separated into three distinct groups (Green/Yellow Vegetables; Oranges/Tomatoes/Grapefruit; Potatoes/Other Fruits/Veggies) | Combined into two groups (Fruits and Vegetables) and recommended to fill half the plate | 
| Fats | Butter and fortified margarine were a separate group | Emphasized as a separate, smaller component (like oils) or incorporated into other groups | 
| Grain Type | Included 'enriched' or 'restored' grains in addition to whole grains | Strong emphasis on whole grains | 
| Serving Guidance | Focused on having a variety from each group every day, with less emphasis on specific portion sizes | Uses visual cues (like a plate) and specifies recommended portion sizes for daily intake | 
| Physical Activity | Not included in the original graphic or messaging | Explicitly included in later iterations, such as MyPyramid | 
This comparison highlights the evolution of nutritional science and public health goals. While the Basic 7 was pragmatic for its time, modern guidelines reflect a greater understanding of macronutrients, chronic disease prevention, and the importance of physical activity.
Conclusion
The 1943 Guide to Good Eating, with its seven distinct food groups, was a landmark piece of nutritional guidance born from the necessities of a wartime economy. It provided a simple, structured approach for citizens to navigate the complexities of rationing while maintaining their health. The guide's division of fruits and vegetables into separate, vitamin-specific categories and the elevation of butter and fortified margarine to its own group stand as unique markers of its historical context. While superseded by more modern and scientifically advanced dietary models like MyPlate, the Basic 7 remains a fascinating and foundational chapter in the history of American nutrition.

Frequently Asked Questions
How many food groups did the 1943 guide have?
The 1943 Guide to Good Eating, also known as the Basic 7, featured seven distinct food groups.
What were the seven food groups in the 1943 guide?
The seven groups were: Green and Yellow Vegetables; Oranges, Tomatoes, and Grapefruit; Potatoes and Other Vegetables and Fruit; Milk and Milk Products; Meat, Poultry, Fish, or Eggs; Bread, Flour, and Cereals; and Butter and Fortified Margarine.
Why did the USDA introduce the Basic 7 in 1943?
The USDA introduced the guide to help American citizens maintain a nutritious diet during World War II, a period of widespread food rationing and shortages.
Was butter really its own food group in 1943?
Yes, in the 1943 Basic 7 guide, butter and fortified margarine were classified as their own separate food group to ensure sufficient Vitamin A intake and to help with satiety.
How did the Basic 7 differ from the later food pyramids?
The Basic 7 did not focus on portion sizes or a pyramid shape, but rather emphasized getting a variety of foods from all seven groups daily. Later pyramids, like the 1992 version, used a tiered structure to represent recommended serving amounts.
Did the 1943 guide mention physical activity?
No, the original Basic 7 guide focused exclusively on food groups and variety, without incorporating a physical activity component. Physical activity was later added to nutritional guidance, such as the 2005 MyPyramid.
How were fruits and vegetables categorized in the Basic 7?
Fruits and vegetables were separated into three distinct groups based on their nutrient content: Green and Yellow Vegetables (Vitamin A), Oranges/Tomatoes/Grapefruit (Vitamin C), and Potatoes and Other Fruits/Veggies (fiber and carbs).
