Which class of nutrients is critical for maintaining body temperature and protecting organs?

1. Proteins

2. Fats

3. Carbohydrates

4. Vitamins

The correct answer is: Fats

Fats play a crucial role in maintaining body temperature and protecting vital organs. They serve as an insulatory layer under the skin, which helps to retain heat and regulate body temperature. Additionally, fats are involved in cushioning and protecting internal organs from trauma, as they surround these organs and absorb impact. This protective function is especially important for organs like the kidneys and heart, which need to be safeguarded from physical stress. Moreover, fats are also essential for the absorption of fat-soluble vitamins (A, D, E, and K), which contribute to overall health and wellbeing. While proteins, carbohydrates, and vitamins are also important nutrients, their primary roles do not focus on insulation and organ protection to the same extent as fats. This makes fats the correct choice when specifically identifying the nutrient class critical for these functions.
