What Your Child Eats May Affect Blood Sugar Control and Inflammation in Type 1 Diabetes

The Dietary Inflammatory Index, or DII, is a scoring system that measures how inflammatory a diet might be based on the foods someone eats. Some foods and nutrients promote inflammation in the body, while others help reduce it. A higher DII score means a diet has more pro-inflammatory properties; a lower score means the diet is less inflammatory.

Researchers studied 78 children and adolescents with Type 1 diabetes, ages 5 to 19, tracking what they ate over three days and measuring their blood sugar control, cholesterol levels, and inflammatory markers. They calculated a DII score for each child based on their dietary records.

After adjusting for factors like age, sex, body weight, calories eaten, and how long they'd had diabetes, the researchers found clear patterns: children eating more pro-inflammatory diets had higher HbA1c levels, higher LDL cholesterol, and more inflammatory substances circulating in their blood. They also had higher levels of leptin, a hormone linked to body weight, and lower levels of adiponectin, a protective hormone.

The pro-inflammatory diets contained more total fat, saturated fat, and cholesterol, but less fiber and protective nutrients like vitamins A and E, omega-3 fatty acids, and beta-carotene.

Blood sugar control is central to managing Type 1 diabetes, and HbA1c is the standard way doctors measure how well that control is working over time. This study suggests that diet composition—not just carbohydrate counting—may play a role in how well children's blood sugar stays managed.

Inflammation itself is important to pay attention to in diabetes, because chronic inflammation is linked to long-term complications including heart disease. This research adds to growing evidence that the types of foods children choose may influence both their immediate blood sugar control and their long-term cardiometabolic health.

This is an observational study, meaning it shows associations between diet patterns and health outcomes—not that one directly causes the other. The findings don't prove that changing the inflammatory potential of diet will improve blood sugar control, only that the two are connected in this group of children.

Families managing Type 1 diabetes typically work with their healthcare team on carbohydrate counting and insulin dosing. Nutritional management is already recognized as central to care. These results suggest that families might also consider the quality and nutrient density of foods alongside carbohydrate content, though individual nutrition decisions should always be made in consultation with a dietitian and diabetes care team who know the child's specific situation.
