美国发布2025 - 2030年饮食指南, 要求更多全食、少糖、高蛋白质摄取量。 The U.S. releases 2025–2030 Dietary Guidelines urging more whole foods, less sugar, and higher protein intake.

美国发布了新的《2025-2030年饮食指南》,建议增加全食品的蛋白质摄入量,减少加糖和加工食品的消费,并重点关注最低加工和营养含量选择。 The U.S. released new 2025–2030 Dietary Guidelines recommending increased protein intake from whole foods, reduced consumption of added sugars and processed foods, and a focus on minimally processed, nutrient-dense options. 与以前版本相比,10页的文件大大简化,强调全谷物、水果、蔬菜和健康脂肪,包括肉类和奶制品等动物来源,同时将饱和脂肪限制在每日热量的10%。 The 10-page document, a significant simplification from previous versions, emphasizes whole grains, fruits, vegetables, and healthy fats, including animal-based sources like meat and dairy, while limiting saturated fat to 10% of daily calories. 它建议每公斤体重1.2至1.6克蛋白质,并劝阻非营养性甜食者。 It advises 1.2 to 1.6 grams of protein per kilogram of body weight and discourages non-nutritive sweeteners. 这些准则的发布没有科学小组的投入,科学小组发现关于超处理食品的证据太不确定,将影响联邦方案,如《国家学校午餐方案》,尽管实施可能需要数年时间。 The guidelines, issued without input from a scientific panel that found evidence on ultraprocessed foods too uncertain, will influence federal programs like the National School Lunch Program, though implementation may take years.
