Discuss how fats, proteins, and carbs are digested and absorbed in the body, and describe the benefits from a dietary perspective. What are the good fats, bad fats, etc.? Why is fiber so beneficial?

Fats, proteins, and carbs are chemically digested and absorbed in the body. To do this there are organs that secrete enzymes that break down fats, proteins and carbs. The first place digestion of fats, proteins, and carbs takes place is in the mouth with saliva breaking down carbs as chewing the food takes place. Once the food is swallowed and has entered the stomach, gastric juices which is usually a mixture of water, enzymes, and hydrochloric acid further break down the food (Sizer & Whitney, 2011). Now in the intestine an emulsifier called bile is secreted along with pancreatic juices. Pancreatic juices have the ability to digest fats, proteins, and carbs. Bicarbonate is released in the intestine to neutralize stomach acids. “Digestion by human enzymes and absorption of carbohydrates, fat, and protein are essentially complete by the time the intestinal contents enter the colon (Sizer & Whitney, 2011).”

The benefits from a dietary perspective are that optimal function can be achieved through the digestion and absorption of fats, proteins, and carbs. Along with the digestion, it is important to factor in fiber. Fiber aids in digestion by binding to cholesterol and minerals. It is indigestible but can aid in the prevention of atherosclerosis and diabetes.

The ‘good’ fats in a diet are those that are unsaturated, like monounsaturated fats and polyunsaturated fats. The ‘bad’ fats are saturated fats and they are full of hydrogen. Hydrogenated oils should be avoided as they are trans-fat which is a type of fat that has hydrogen added to it.

To conclude this blog and part of the final, fats, proteins, and carbs, and even fiber, are all needed for regulatory functions. I have noticed that it’s a balance of the proper of nutrients. From my experience and education, you cannot limit one (fats, proteins, & carbs) to no longer be a part of your diet nor can you overindulge in one or more. Well, you can but as I’ve learned through trial and error that you don’t feel well and everybody thinks you look sick because you are not eating properly or you gain weight because you’re eating way to good (unhealthy).
