Your diet should be aligned to region you're living/upbringing. Don't just eat something because it is healthy which is what most of people are doing these days. Body, mind and Nature/Surrounding should be aligned with each other. Your mental health plays big role in physical health and vice versa. Whatever you eat, remember important thing is body movement. Keep moving as naturally as possible (exercise, walking, playing). For many people gym is not sustainble but you can always adopt another physical activity which is natural to you.
