apple has a sugar content of up to 15%. This means that an apple weighing about 100 grams now contains the equivalent of more than four teaspoons of sugar. The findings have also shown that sugar intake among children has risen to alarming levels compared to only ten years ago. They eat about as much sugar as adults, but, of course, adult consumption is far smaller relative to body size.
