Assignment 4: Tracking Carbohydrates, Lipids and Proteins

Chapter 4:

1.     Discuss why the statement “carbohydrates make us fat” is not accurate considering peoples’ diets in other parts of the world.

2.     How are carbohydrates and diabetes related to each other?

3.     Why are people who consume many of their carbohydrates in the form of high-fructose corn syrup (HFCS) more apt to overeat than people who consume carbohydrates in the form of starches?

4.     Why is it difficult to attribute the increase in obesity and related illnesses to added sugars alone?

Solution

1). After absorption from the food, glucose is metabolized to produce ATP by cellular respiration. However, our body does not use all the glucose at a time, so, the excess glucose is stored in the body.

The fates of glucose other than the cellular respiration are.

1). Excess glucose absorbed from the food is converted into glycogen by the hormone insulin (released from the beta cells of pancreas).

2). Conversion of glucose into fat by a process called “lipogenesis.” Lipogenesis occur in the liver cells and cells of adipose tissue.

Thus, the excess glucose is mostly stored in the form of fat, which gradually leads to obesity if it is not consumed for energy production.

Not only foods rich in carbs, but foods rich in fat and sedentary life styles are also the primary causes of obesity. And the statement \"carbohydrates makes us fat\" is not appropriate for those who are taking \"adequate carbohydrates but not excess carbohydrates.\"
