definitely a culture thing, italians believe in REAL food and small portions, americans believe in NO-FOODS and big portions. don’t know what the rest of the world believes though.
my american friend likes no fat, no sugar, no dairy, no gluten, no everything (even he isn’t food intolerant to anything). instead he likes protein shakes, big portions of chicken, 6 egg white omelets loaded with lean bacon, whole wheat pizza loaded with fat free mozzarella and chicken, low fat sourcream, fat free cream cheese. he always eats until the belly is full an explodes.
my italian friend likes full fat, real sugar, dairy galore, daily non-whole wheat pasta, yes real food. he detests protein shakes, chicken, he eats only 1 egg a day or less, bacon only for carbonara, full fat creme fraiche. he eats in moderation, never till full.
p.s. one time i asked my american friend to make me his signature 3-egg omelet but using only the yolks and not the whites, because if you think of it, whites also have calories, and till this day he thinks my 3 egg yolk omelet is less healthy than a 3 whole egg one.
