The Dietary Guidelines for Americans (DGA) shape federal nutrition programs, clinical counseling, and food industry practice for an estimated 330 million people. The 2025-2030 edition, released in January 2026, departs substantially from prior editions. This narrative review appraises the new DGA from a preventive cardiology standpoint, mapping its major recommendations onto current cardiometabolic evidence and consensus statements of major cardiovascular and nutrition societies. The 2025-2030 edition aligns with current cardiometabolic evidence in limiting added sugars, emphasizing fruits, vegetables, and whole grains, and retaining the cap on saturated fat at less than 10% of daily energy. It diverges, however, on several issues, such as dropping the longstanding recommendation to replace saturated fat with unsaturated fat, framing well-planned vegetarian and vegan patterns as excessively at risk of nutritional deficiencies, and endorsing full-fat dairy and animal cooking fats. Furthermore, it raises protein targets, removes the quantitative alcohol limits carried out since 1990 despite evidence of dose-dependent harm, reintroduces a food pyramid that was not consumer-tested and omits sustainability and equity. This review is organized by dietary component, distinguishing recommendations that contradict evidence from those that either extrapolate beyond the current evidence or that lack practical operationalization. We examine governance and conflict-of-interest concerns, including industry ties among authors of the supporting Scientific Foundation, and we examine affordability. We close with proposals for the next revision cycle that separates population guidance from targets clinicians can apply to high-risk patients, and outline a research agenda to address current evidence gaps.
