Insights
High simple sugar intake in infant formula may increase LDL cholesterol. Formula-fed infants show higher glucose, insulin, and proprotein convertase subtilisin/kexin type 9 levels, linking sugar to early childhood high cholesterol.
Area of Science:
- Pediatrics
- Cardiovascular Health
- Nutritional Science
Background:
- Hypercholesterolaemia is a significant risk factor for cardiovascular disease.
- Cholesterol levels increase substantially from infancy to adulthood.
- Low rates of exclusive breastfeeding and high consumption of simple carbohydrate-rich formulas are prevalent in the USA.
Purpose of the Study:
- To investigate the potential link between simple sugar intake in infant formula and elevated LDL cholesterol in early childhood.
- To explore the association between formula feeding, glucose/insulin spikes, and proprotein convertase subtilisin/kexin type 9 (PCSK9) levels.
Main Methods:
- Observational study comparing cholesterol levels in neonates, infants, and adults.
- Analysis of infant feeding practices, specifically breastfeeding vs. formula consumption.
- Measurement of fasting glucose, insulin, and PCSK9 levels in formula-fed infants.
Main Results:
- Formula-fed infants exhibit higher levels of fasting glucose and insulin compared to breastfed infants.
- Elevated proprotein convertase subtilisin/kexin type 9 (PCSK9) levels were observed in formula-fed infants.
- These findings suggest a correlation between simple carbohydrate intake and increased LDL cholesterol in early life.
Conclusions:
- High intake of simple sugars from infant formulas may contribute to increased LDL cholesterol in early childhood.
- Formula feeding practices, characterized by simple carbohydrate-rich products, warrant further investigation regarding long-term cardiovascular health implications.
- Early life nutrition significantly impacts cholesterol metabolism and cardiovascular risk factors.
Abstract:
Hypercholesterolaemia is an important risk factor for cardiovascular disease. Both total and LDL cholesterol levels are three-fold higher at the end of the first year of life and about four-fold higher in adulthood compared with the neonatal period. In the USA, only 25% of infants are exclusively breastfed and simple carbohydrate-rich formulas are preferentially consumed. Spikes in fasting glucose and insulin have been reported in formula-fed infants and are associated with higher levels of proprotein convertase subtilisin/kexin type 9, suggesting a potential link between high simple sugar intake and consequent increase in LDL cholesterol in early childhood.

Glucose Transporters
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:
Overview of Carbohydrate Metabolism
Glucose transport into cells is facilitated by a family of transport proteins called GLUT (Glucose Transporters). GLUT4 is the primary glucose transporter for insulin-stimulated glucose...
