AJCN: Dairy products have no benefit in regulating blood sugar

Previous studies have shown that higher levels of fatty acid biomarkers (dairy fat intake) are associated with a lower incidence of type 2 diabetes.
, however, few trials have assessed the effects of dairy products on blood sugar stability, including fermented or full-fat dairy products.
recently, a study published in The American Journal of Clinical Nutrition compared the effects of eating low-fat milk, whole-fat milk, yogurt and cheese on blood sugar level regulation in people with metabolic syndrome.
the study, the researchers included 72 people with metabolic syndrome and divided them into three groups: the Restricted Dairy Diet Group, the Low-Fat Dairy Diet Group, and the Full-Fat Dairy Diet.
in the restricted dairy diet group, patients consume up to 3 times a week of skimmed milk.
in the low-fat dairy diet group, patients were treated with skimmed milk, skimmed yogurt and low-fat cheese more than 3 times a day.
in the full-fat dairy diet group, more than 3 times a day full-fat milk, full-fat yogurt and full-fat cheese.
12 weeks, the researchers measured glucose tolerance, insulin sensitivity, systemic inflammation, liver fat content, and weight in each group of patients.
showed no intervention in blood sugar regulation, regardless of dairy products.
-fat and full-fat dairy diets reduce insulin sensitivity compared to restricted dairy diets.
same time, weight also changed in three groups, with weight gain in patients on a full-fat dairy diet and no significant change in weight in patients on a low-fat dairy diet compared to the restricted dairy diet.
, there was no significant change in liver fat levels or systemic inflammation in the three groups.
, even if dairy food can reduce insulin sensitivity, it does not improve blood sugar levels in people with metabolic syndrome.
when assessing the effects of milk on overall health, the effects of food on blood sugar are only one of many considerations.
