What are the digestion, absorption, and metabolism of the macronutrients?






As we consumed our food, the  next process is digestion and distributing the nutrients where it is needed. Consuming carbohydrates such as complex carbs are mainly digest and the body will use it as an energy source. Carbohydrates that high in sugar and fat are considered simple carbs, generally stored as fat. The chemical reaction of enzymes “amylase” helps to digest carbs and absorb it for energy. Simple carbs such as refined sugar, are mainly stored in the fat cells, which has no value for the body. Complex carbs are useful to the metabolism and energy that the body demands. During the digestion, protein releases an amino acid that accommodate the growth and development of the muscles tissues. As the enzymes speed up the process of the digestion of protein. It is necessary to Include protein with three main meals to provide enough energy to keep your metabolism running throughout the day. “When a person eats food proteins, whether from cereals, vegetables, beef, fish, or cheese, the body must first alter them by breaking them down into amino acids; only then can it rearrange them into specific human body proteins.” Sizer, F. & Whitney, E. (2013). We have good, and bad fat in the food that we eat. Once the fat is digested it is carried through the blood stream and is used to fuel the body. Again, too much consumption of fat will be stored in the body instead of using it for energy. All of the Macronutrients are good for our, too much of it can do just as much harm. One thing that all three of the macronutrients have in common is, it fuel the body to sustain your daily activities.
