While pimples are not as simple as too much milk or sugar in your diet, both have a significant impact. Nutritional deficiencies as well as excesses can worsen acne.
Our typical Western diet is full of inflammatory fats - saturated fats, trans fats, too many omega-6, inflammatory, processed vegetable oils like soy and corn oils. These increase IGF-1 and stimulate pimple follicles.
I've been more or less vegetarian for about 40 years. Health diet really helps. I do meditation every day, and either yoga or sport several times a week.
For the sake of argument and illustration I will presume that certain articles of ordinary diet, however beneficial in youth, are prejudicial in advanced life, like beans to a horse, whose common ordinary food is hay and corn.
For most of my 20s, I looked like I was 12. Now that I'm pushing 40, I guess I look closer to... 15? It must be my macrobiotic diet. Oh, wait, except that I don't have one of those.
I don't diet, I don't do fads, I've just decided to not eat carbs. So no more bread and pasta for the month. I can't live without chocolate, though. I've always got a bar in my handbag. It has to be 72%. Any less and it's too sweet, any more and it's inedible. Like I said, I'm very particular.
