Food questionnaires are fake science: let us look at spoons

All is for water
tea spoon UK = 3,5516328125 g no more no less
tea spoon US = 4,92892161458 g more precise
coffee spoon Fr = 5 g

You understand why I am not going through the details of the different cups bowls and other subtle differences of our culinary ware...

But I don't resist to quote the WHO:
"4 MARCH 2015 ¦ GENEVA - A new WHO guideline recommends adults and children reduce their daily intake of free sugars to less than 10% of their total energy intake. A further reduction to below 5% or roughly 25 grams (6 teaspoons) per day would provide additional health benefits."
We are in a mess.
