Compare per 100g or per 100 calories. Suggested serving amount implies an amount that is considered appropriate to consume at one time. Which is fine for non-essential foods but nonsensical for baby formula.
BTW manufacturers can (and do) play games with the suggested serving amount to make their product appear healthier or more desirable. Standardize on a common denominator for a product category and stick to it. Then, if needed, call out how many units of the product are in that standard size.
GP's point is that you're not going to significantly reduce the suggested serving size of an essential food on account of having made it sweeter because the other nutrients are still needed.
A person's caloric and nutrient needs will vary from moment to moment, a suggested daily serving is merely an average value for average people used as an objective frame of reference.
And if we're going to argue whether a food has more or too much sugar than other foods, we need to use an objective frame of reference as a point of comparison.
Anyway, the Nestle hate in this overall thread is just as worthless as the Boeing bashing and Musk Derangement Syndrome seen in other threads.
"An objective frame of reference" sounds like it should be standardized. A suggested serving amount is pretty arbitrary and up to the manufacturer to determine, and is the opposite of "objective".
For formula-fed infants the suggested serving amount is "exactly as much they want".
