2. Health awareness: not picky about food may also indicate that this person has a strong health awareness. They may be aware of the health benefits and nutritional value of different foods, so they prefer a balanced diet and avoid excessive preference for certain foods.
3. Regional culture: In some regions or cultures, people may be more accustomed to trying different foods, so not picky about food may also be related to their regional cultural background.
