Final answer:
Removing chicken skin is recommended to reduce fat intake and avoid harmful substances. Wrapping food tightly in foil before freezing minimizes freezer burn by preventing air from drying out the food's surface.
Step-by-step explanation:
It is generally recommended to remove the skin from chicken before eating it to reduce the intake of fats, particularly saturated fats, which are prevalent in the skin. The skin is also where potentially harmful substances can accumulate. Therefore, removing it can decrease the consumption of these substances, contributing to a healthier diet.
When freezing foods, wrapping it tightly with foil is advisable to minimize freezer burn. Freezer burn occurs when air reaches the food's surface and dries it out. Tightly wrapped foil prevents air from coming into contact with the food, thus reducing the risk of oxidation and moisture loss that leads to freezer burn.
