This is mainly due to the fact that sugar and fat (and salt) are strong flavour carriers and are therefore almost never dispensed with.
For this reason, there are three typical ways of marketing ‘healthy’:
With fruit content. However, fruit is often rather insignificant and people are more likely to eat even worse because they have already eaten something healthy. In addition, fruit has a high sugar content and not a few calories and the same applies to such products.
Less sugar. But instead more fat.
Reduced fat. But more sugar.
With vitamin ABCX. And of course – exactly – with lots of sugar and fat.
I look at the list of ingredients and the nutritional values of EVERY food. It is worth it!
