US 2025-2030 Dietary Guidelines: Addressing Alcohol Intake Recommendations

The US Department of Health and Human Services and the US Department of Agriculture released the 2025-2030 Dietary Guidelines for Americans on January 7, 2026. Along with establishing the first-ever limit on processed foods, firmly encouraging a focus on whole foods, and recommending a higher proportion of protein, the guidelines come with several uncertainties and limitations.1

Prominent among these uncertainties is a significantly broader suggestion of how people should manage their alcohol intake. Rather than explicitly stating a recommended number of drinks, the guidelines now advise patients to limit their alcohol intake. To address and attempt to explain this vague suggestion, Diabetes Dialogue cohosts Diana Isaacs, PharmD, and Natalie Bellini, DNP, met with Susan Weiner, MS, a nationally recognized dietitian and diabetes care and education specialist.

Weiner opens by raising substantive concerns about revisions to alcohol-related recommendations in the newly released US dietary guidelines, emphasizing the clinical and policy implications of shifting from quantitative to more ambiguous language. She notes that previous guidelines clearly defined alcohol limits—less than two drinks per day for men and one drink per day for women—while also specifying standard drink sizes and citing evidence linking alcohol consumption to adverse outcomes such as cancer, liver disease, metabolic dysfunction, and other chronic conditions. In contrast, the updated guidance broadly advises individuals to “drink less,” without numerical thresholds, detailed definitions, or accompanying references to alcohol-related harms. Weiner argues that this lack of specificity reduces the guidance’s practical value for clinicians and increases the risk of misinterpretation by patients, who may rationalize unsafe drinking behaviors under vague recommendations.

The discussion highlights how this ambiguity is particularly concerning in populations with diabetes or alcohol-induced dysglycemia, where alcohol can acutely and chronically disrupt glucose regulation, exacerbate liver disease, and affect multiple organ systems. Bellini reflects on the importance of having firm, evidence-based language that clinicians can reference directly in counseling and documentation, noting that tighter guidance previously served as a useful clinical tool. Bellini expresses worry that the revised wording may be perceived as a loosening of standards, potentially undermining public health messaging at a time when alcohol consumption increased during and after the COVID-19 pandemic.

Beyond individual patient care, the conversation emphasizes that dietary guidelines function as policy instruments. Weiner notes that these recommendations shape nutrition education curricula taught to children, influence school lunch programs, and may affect federal food and nutrition programs such as WIC, SNAP, and even military food services. From this vantage point, changes to alcohol guidance could have broad societal consequences, reinforcing the need for clarity and scientific rigor.

The segment also explores how professional organizations interpret and adopt federal dietary guidelines. Isaacs observes that groups such as the American Heart Association appear to be maintaining more conservative, established recommendations (such as the plate method, emphasis on lean meats, and limiting saturated fats) despite broader inclusions in the new guidelines, including butter and beef tallow. Weiner anticipates that organizations focused on cardiovascular disease, cancer, and metabolic health will publicly scrutinize and potentially challenge the revised alcohol language, given its established links to disease, mental health outcomes, and excess caloric intake. The discussion concludes with the expectation that further debate and guidance from professional societies will emerge, underscoring that alcohol cannot be excluded from clear, evidence-based dietary recommendations.
