Reinforces what was already believed, rather than introducing something new.
This randomized crossover trial of 30 adults with overweight/obesity found that 6 weeks of increased mixed-dairy consumption (3 servings/day) did not attenuate postprandial inflammatory, metabolic, antioxidant, or vascular responses to a high-fat meal challenge compared with a low-dairy diet (≤1 serving/day). The study confirms that while acute dairy exposure may have anti-inflammatory effects, habitual dietary intake of dairy does not translate to modifications in the acute postprandial response to a high-fat meal.
Randomized crossover trial. Adults with overweight/obesity (BMI 32.0±4.5 kg/m²); 18 female and 12 male participants.. Intervention: Higher-dairy diet: 3 servings/day of mixed dairy products (milk, yogurt, and cheese) for 6 weeks.. Compared with: Lower-dairy diet: ≤1 serving/day of mixed dairy products for 6 weeks.. n = 30. Not stated..
No significant trial*time interactions observed for any measured outcome (inflammatory, metabolic, antioxidant, vascular). Interleukin-6 showed significant main time effect (p=0.013) with pre vs 6h change of Δ0.49 pg/mL, but no between-group difference. Triglycerides showed significant main time effect (p<0.001) with pre vs 6h change of Δ0.744 mmol/L, but no between-group difference.

Clinicians should note that while acute dairy consumption may attenuate postprandial inflammation, counselling patients to increase habitual dairy intake as a strategy to improve postprandial metabolic or inflammatory responses to high-fat meals is not supported by this evidence. The null finding suggests that chronic dietary modification alone may not replicate acute anti-inflammatory effects.
A well-designed randomized crossover trial that confirms the absence of a hypothesized benefit, showing that habitual dairy consumption does not modify postprandial responses to high-fat meals despite acute dairy effects being known.

Consuming dairy products acutely prior to a meal has been shown to attenuate postprandial inflammation, but it is unclear if increasing dairy consumption habitually within the diet imparts similar benefits to this acute inflammatory response. The purpose of this study was to compare postprandial inflammatory, antioxidant, metabolic and vascular responses to a high-fat meal challenge (HFMC) following 6-weeks of a habitually higher mixed-dairy diet vs. 6-weeks of a low mixed-dairy diet. Using a randomized crossover design, 30 participants with overweight/obesity (OW/OB) (18/12 female/male; BMI: 32.0±4.5 kg/m 2 ) completed two, 6-week dietary interventions separated by a ≥4-week washout, consisting of either: 1) a higher-dairy (HD) diet (3 servings/d total: milk, yogurt and cheese) or 2) lower-dairy (LD) diet (≤1 serving/d). Participants then consumed a high-calorie, high-fat, fast-food, breakfast meal and had blood drawn pre-meal and postprandially (1h, 2h, 4h, 6h). Vascular measurements and muscle biopsies were taken pre-meal and 4h postprandially. There were no significant trial*time interactions, but significant main time effects were observed for inflammatory (interleukin-6: p=0.013; pre vs 6h=Δ0.49pg/mL), metabolic (triglycerides: p<0.001; pre vs 6h=Δ0.744mmol/L), antioxidant (total blood glutathione: p=0.021; pre vs 4h=Δ-0.101μmol/g Hb) and vascular measurements (systolic blood pressure: p=0.006; pre vs 4h=Δ4 mmHg) across the postprandial period. In conclusion, while the HFMC induced minor inflammatory, lipid, antioxidant and vascular postprandial responses, 6-weeks of increased mixed-dairy product consumption did not further modulate these responses. This lack of effect may be attributed to the intervention not altering acute digestion and absorption kinetics of the high-fat meal.
