1. Present simple and present continuous: The answer uses the present simple ("I tend to eat," "I have," "I just stick") to describe habits and preferences, and the present continuous ("These days, supermarkets offer...") to describe current trends, showing good control of tense.
2. Complex sentences: The use of linking words like "mainly because," "so," and "regardless of" helps to create complex sentences and logical connections, which are important for higher band scores.
