The Dietary Guidelines for Americans (DGA) are a key source of nutrition advice in the U.S., updated every five years by the USDA and HHS. The 2020-2025 edition provides recommendations for all ages, emphasizing healthy eating patterns based on personal and cultural preferences within calorie limits.
Limiting Key Dietary Components
A major focus of the DGA is reducing intake of certain components commonly overconsumed, allowing more room for nutrient-dense foods.
Added Sugars
Limit added sugars to less than 10% of daily calories for those aged two and older. Avoid added sugars entirely for children under two. Sugary drinks and desserts are primary sources.
Saturated Fat
The DGA recommends consuming less than 10% of daily calories from saturated fat for individuals aged two and older. This means choosing leaner meats, low-fat dairy, and replacing saturated fats with unsaturated fats from sources like seafood and nuts.
Sodium
The guidelines suggest limiting sodium to under 2,300 milligrams daily for ages 14 and up, with lower limits for younger individuals. Processed foods and restaurant meals contribute significantly to sodium intake.
Promoting Nutrient-Dense Foods
Increasing consumption of nutrient-dense foods and beverages is another core recommendation, helping individuals meet nutritional needs efficiently.
- Vegetables: Eat a variety from all subgroups.
- Fruits: Prioritize whole fruits over juice.
- Grains: Make at least half your grains whole grains.
- Dairy: Choose fat-free or low-fat options, including fortified soy beverages.
- Protein: Vary sources, including seafood (8 oz/week for adults), lean meats, poultry, eggs, legumes, and nuts.
Comparison of Recommendations for a Healthy Eating Pattern
| Dietary Component | Recommended Guideline (2020-2025) | Why it's Recommended |
|---|---|---|
| Added Sugars | <10% of total daily calories for ages 2+; avoid under age 2 | Helps manage calorie intake and reduces chronic disease risk. |
| Saturated Fat | <10% of total daily calories for ages 2+ | Lowers blood cholesterol and reduces cardiovascular disease risk. |
| Sodium | <2,300 mg per day for ages 14+; less for younger children | High intake is linked to high blood pressure. |
| Seafood | At least 8 ounces per week for adults | Provides essential nutrients like omega-3 fatty acids. |
| Whole Grains | Make at least half your grains whole grains | Good source of fiber and nutrients. |
| Dairy | Fat-free or low-fat dairy options | Provides calcium, potassium, and vitamin D with less saturated fat. |
Conclusion
The Dietary Guidelines for Americans recommend building a healthy eating pattern focused on nutrient-dense foods while limiting added sugars, saturated fat, and sodium. This framework helps individuals make healthier choices to improve health and reduce the risk of chronic diseases. The guidelines offer a flexible approach, encouraging personalized choices that fit individual needs, culture, and budget.
Adhering to the Dietary Guidelines
Implementing the DGA involves making gradual, sustainable changes. Simple shifts, like choosing water over sugary drinks or incorporating more seafood and legumes into meals, can make a significant difference. The DGA serves as a long-term guide for healthy eating.
