Mid‑July analyses continued to reinforce the emerging consensus that full‑fat dairy, including ultra‑high‑temperature (UHT) milk, does not pose intrinsic cardiovascular risks. A July 12 overview explained that UHT processing (135–150 °C for seconds) destroys most microbes and extends shelf life without altering protein, calcium or energy content; only modest losses of heat‑sensitive vitamins (B12, folate, C) occur. Reported health complaints are linked to lactose intolerance or milk‑protein allergy, not the aseptic packaging. The same overview cited a 25‑year cohort study showing a 24 % lower risk of coronary artery calcification among high full‑fat dairy consumers, suggesting benefits from calcium, potassium, vitamin D, or displacement of less healthy foods. Parallel meta‑analyses of 22 European and North American studies, published in Nutrition Research on 14 July and reiterated on 16 July, found that naturally occurring trans fats in butter, cheese, milk and yogurt are not associated with increased cardiovascular disease, distinguishing them from industrial trans fats. In August, new findings from a University of Toronto study published in The Journal of Nutrition further challenged guidelines favoring low-fat dairy. The 12-week trial involving 74 overweight adults found that consuming three daily servings of full-fat dairy did not increase body weight, alter body composition, or raise cholesterol levels compared to a low-dairy diet. Participants consuming full-fat dairy showed lower blood pressure and higher intakes of calcium, protein, and vitamin D. Researchers suggested these results support the ‘dairy-matrix’ hypothesis, arguing that the nutritional impact of dairy depends on its complex food structure rather than individual nutrients like saturated fats alone. The study noted that full-fat dairy may be associated with a lower risk of metabolic syndrome, type-2 diabetes, and hypertension. Lead author G. Harvey Anderson, Ph.D., remarked that ‘the fear of fat in dairy has completely misled us about dairy and its advantages.’
