Limes are small, round, and green, while lemons are usually larger, oval-shaped, and bright yellow. Nutritionally, they're almost identical and share many of the same potential health benefits. Both fruits are acidic and sour, but lemons tend to be sweeter, while limes have a more bitter flavor.
Lemons have significantly more citric acid than limes. Plus, they are an excellent source of potassium and magnesium. But, when it comes to other nutrients, lime fruits are actually a bit healthier. They contain higher concentrations of phosphorous, vitamins A and C, calcium, and folate.
