If really depends on what you're eating, because some foods have added lemon juice on them, like meat, fried rice, and such, while others, like a regular steak, are basic because it literally just has meat on it. But if you really want my opinion, I think that most foods are more likely to be acidic, like coffee, eggs, butter, fruit, cereal, as well as much more daily things that we eat. Although we also eat many basic common foods, acidic foods are much more common in your regular daily meal.
