Three servings of full-fat dairy a day: a 12-week study found no negative effect

Findings have been published suggesting full-fat dairy may be healthier than conventional dietary advice has assumed. In a 12-week study, adults who ate three servings a day showed no meaningful negative effects.

The relationship between saturated fat and dairy has long been contested in nutrition science. The view that the dairy matrix — the food as a whole — may behave differently from its individual nutrients has gained ground in recent years.

Researchers stress that a single study does not change dietary guidelines. Even so, the findings add weight to calls to reassess classifications built on fat content alone.

MHA Analysis

It is true that a single study does not move dietary guidelines, but this finding is not alone — the view that the dairy matrix behaves differently as a whole than its individual nutrients has gained ground steadily. The trouble with classifying by fat content is that it places cheese and butter in the same bracket despite the same saturated fat behaving differently in each. Twelve weeks is reasonable for metabolic markers but short for cardiovascular outcomes, which is why this reads as a call to reconsider the classification rather than a licence.
