Comparison of the Nutritional Values of Infant Formulas Available in Saudi Arabia

Sugar content in infant formula: Accuracy of labeling and conformity to guidelines

BACKGROUND

Infant formulae are a primary source of nutrition during the first years of life, to which sugars are frequently added. This may contribute to adverse dental health problems if consumed excessively when coupled with prolonged and nocturnal feeding habits.

AIM

To assess the amount and type of dietary sugars in commercially available infant formulae in the UAE.

DESIGN

Sucrose, glucose, and fructose were measured in 71 different brands of commercially available infant formulae for retail sale in the UAE. Analysis was performed using high-performance liquid chromatography with refractive index detection. Sugar values were compared with the reported levels on the nutritional labels. A comparison between findings, product labels, and international standards for infant formulae was performed.

RESULTS

Of the 71 samples, 23 had detectable sugar levels, varying between sucrose, glucose, and fructose. Ten samples were found to have sugars contributing to more than 5% of total energy intake ranging between 5.68% and 27.06%. All infant formula packages had carbohydrate levels mentioned on the labels, but very few mentioned the added sugar content.

CONCLUSIONS

Many infant formula products tested contained sugars that exceeded the standard recommended intake. Tighter regulations that monitor the amount of sugar in infant formulae and guidelines for comprehensive labeling systems are required.

A systematic comparison between infant formula compositions using the Bray-Curtis Similarity Index

BACKGROUND

Making an informed choice between the available infant formulas is challenging, as there is no unbiased tool allowing a systematic comparison between the very long lists of infant formula compositions.

AIM

The aim is to present the Bray-Curtis Similarity Index (BCSI) as a tool for systematic comparison between standard stage-1 infant formula (SS-1-IF) compositions.

METHODS

We obtained the nutrient levels from the packaging labels of 23 SS-1-IFs available in Al-Ahsa, Saudi Arabia, in April 2018. The international legislations that launched infant formula standards endorse targeting the minimum rather than the maximum proposed nutrients levels. Thus, we blindly compared between displayed nutrients levels on each of the 23-studied SS-1-IF and the minimum international proposed nutrient levels via using the BCSI.

RESULTS

The range of the total displayed components was 38-57. Except for docosahexaenoic acid, all displayed components were within the standard recommended range. The BCSI summarized all displayed nutrients in a single number. The BCSI of the studied SS-1-IF ranged from 0.4141 to 0.79730. We ranked the 23 studied SS-1-IFs based on the higher BCSI is the closer to the minimum proposed nutrient levels. A dendrogram segregated the SS-1-IFs into four clusters based on their BSCI and total numbers of all displayed components.

CONCLUSIONS

We think the BCSI is an appropriate tool for a systematic comparison between SS-1-IFs compositions and may help for choosing a SS-1-IF.
