Some people like to add lemon to dishes because of its fragrant, mildly sour flavor. However, experts advise against squeezing lemon onto hot food to maximize the nutritional value of this fruit.

This habit destroys the vitamin C in the lemon, and you won’t get the full benefits,” she added.
The expert advises that whenever you want to use lemon in cooking, let the food cool down a bit before squeezing the lemon juice on it.
Dr. Sawinder Kaur, Head of Food Technology and Nutrition at Lovely Professional University (India), agrees with this view: “Vitamin C is sensitive to temperature and light. The degradation of vitamin C can occur at temperatures from 30°C to 85-95°C depending on the exposure time. This vitamin is also water-soluble. Adding lemon juice to hot food can destroy the vitamin and affect the activity of enzymes.”
