美国官方饮食指南被“推翻”了？这几点值得国人餐桌借鉴

Core Viewpoint - The newly released 2025-2030 Dietary Guidelines for Americans emphasizes the importance of consuming "real food" and shifts focus from what and how much to eat, to where food comes from, marking a significant change in U.S. nutrition policy [1][4]. Group 1: Key Recommendations - The new guidelines recommend a diet centered around whole, nutrient-dense foods such as poultry, meat, eggs, seafood, legumes, nuts, whole grains, and intact fruits and vegetables [4][6]. - There is a strict limitation on foods and beverages containing added salt, sugar, artificial flavors, synthetic colors, preservatives, and non-nutritive sweeteners, specifically avoiding highly processed packaged foods [6][9]. - The guidelines encourage home cooking using gentle methods like baking, roasting, and stir-frying, while advising against frying [6][12]. Group 2: Structural Changes - The traditional food pyramid has been fundamentally inverted, placing high-quality proteins, dairy, healthy fats, and fresh fruits and vegetables at the top, while whole grains have been moved to the tip [7][9]. - This inversion signifies a redefinition of food priorities, aiming to shift public focus towards protein-rich foods and away from high carbohydrate intake, which has been linked to obesity and metabolic diseases [10][12]. Group 3: Protein and Fat Recommendations - The new guidelines increase the recommended protein intake for adults to 1.2-1.6 grams per kilogram of body weight, nearly doubling the previous recommendation of 0.8 grams [10][12]. - While the guidelines promote the inclusion of high-fat foods like butter and full-fat dairy, they also set a cap on saturated fat intake at 10% of total daily energy, which could be easily exceeded [15][16]. - The guidelines take a stricter stance on added sugars, recommending zero intake, especially for children under 10, contrasting with the previous guideline of limiting added sugars to 10% of total energy [17][19]. Group 4: Fruit and Vegetable Intake - The guidelines suggest prioritizing colorful, whole vegetables and fruits, recommending a daily intake of 3 servings of vegetables and 2 servings of fruits [20]. - Compared to the Chinese dietary guidelines, which recommend higher vegetable and fruit intake, the U.S. guidelines may appear insufficient for optimal health benefits [21]. Group 5: Cultural Considerations - The principles of "real food," "high-quality protein," and "strict sugar control" in the U.S. guidelines resonate with China's dietary principles of food diversity and balanced intake [21]. - However, it is emphasized that dietary guidelines should be tailored to local populations' epidemiological characteristics and dietary habits, suggesting that the Chinese population should not blindly follow foreign guidelines [21].
