We did a little human testing on our fraternal twin infants. The slightly smaller of the two was fed formula which had HFCS as an ingredient, the other was fed formula not containing HFCS as the sweetener. Our smaller son quickly gained more weight and started to outweigh his brother by a pound. The (initially) smaller twin still outweighs his brother. They are now ~21 lbs and 19 lbs respectively @11mo
