Relation between dietary fat and energy and micronutrient intakes

Area of Science:

• Pediatric Nutrition
• Cardiovascular Disease Prevention
• Dietary Assessment

Background:

• Concerns exist regarding the energy and nutrient adequacy of low-fat diets for children, particularly in Western populations aiming to prevent cardiovascular disease.
• Understanding the relationship between fat intake and nutrient composition in children's diets is crucial for public health recommendations.

Purpose of the Study:

• To analyze the nutrient composition of self-selected low-fat diets in schoolchildren.
• To determine if reduced fat intake compromises energy and nutrient adequacy in children aged 8-12 years.

Main Methods:

• A dietary analysis was conducted on 174 randomly selected schoolchildren (aged 8-12 years) from middle and high socioeconomic groups.
• Nutrient intake and composition were assessed in relation to varying levels of fat consumption.

Main Results:

• Mean energy intake from fat was 31%, with 44% of children consuming less than 30% of energy from fat.
• Lower fat intake correlated with increased intake of sugar, but also higher nutrient densities of thiamin, niacin, folate, vitamin C, magnesium, and iron.
• Increased fruit, vegetable, and grain consumption was noted with decreased fat intake.
• Parental educational level was the primary determinant of fat intake, showing an inverse relationship.

Conclusions:

• Self-selected low-fat diets among children from average to high socioeconomic backgrounds do not appear to compromise major nutrient or energy intake.
• These findings suggest that low-fat dietary patterns can be adequate for children, provided they emphasize nutrient-dense foods like fruits, vegetables, and grains.
