HUMAN NUTRITION

Detailed explanation-1: -Triglycerides, cholesterol and other essential fatty acids-the scientific term for fats the body can’t make on its own-store energy, insulate us and protect our vital organs. They act as messengers, helping proteins do their jobs.

Detailed explanation-2: -Oils and fats supply calories and essential fats and help your body absorb fat-soluble vitamins such as A, D, E and K. The type of fat is just as important for health as the total amount of fat consumed. That’s why it’s important to choose healthier unsaturated fats.

Detailed explanation-3: -Fat is used for energy during exercise, especially after glycogen is depleted. Fats are packed together tightly without water and store far greater amounts of energy in a reduced space. A fat gram is densely concentrated with energy-it contains more than double the amount of energy than a gram of carbohydrate.

Detailed explanation-4: -Adipose cells play several critical roles in systemic metabolism and physiology. There are at least two classes of fat cells-white and brown. White fat is specialized to store energy in the form of triglycerides, an especially efficient method because this class of molecules is highly energetic and stored anhydrously.
