Describe the digestion of carbohydrates?in five sentence.
Answers
Answer:
During digestion, starches and sugars are broken down both mechanically (e.g. through chewing) and chemically (e.g. by enzymes) into the single units glucose, fructose, and/or galactose, which are absorbed into the blood stream and transported for use as energy throughout the body.

Answer:
What are carbohydrates?
Carbohydrates give the body energy to go about your day’s mental and physical tasks. Digesting or metabolizing carbohydrates breaks foods down into sugars, which are also called saccharides. These molecules begin digesting in the mouth and continue through the body to be used for anything from normal cell functioning to cell growth and repair.
You’ve probably heard that some carbohydrates are considered “good” while others are “bad.” But really, it’s not so simple.
There are three main types of carbohydrates. Some carbohydrates are naturally occurring. You can find them in whole fruits and vegetables, while others are processed and refined, and either lacking in or stripped of their nutrients. Here’s the deal:
Types of carbohydrates
The three types of carbs are:
starches or complex carbs
sugars or simple carbs
fiber
Both simple and complex carbohydrates break down into glucose (aka blood sugar). A simple carb is one that’s comprised of one or two sugar molecules, while a complex carb contains three or more sugar molecules.
Fiber, on the other hand, is found in healthy carbs, but isn’t digested or broken down. It’s been shown to be good for heart health and weight management.
Naturally occurring simple sugars are found in fruit and dairy. There are also processed and refined simple sugars that food companies may add to foods such as sodas, candy, and desserts.
Good sources of complex carbohydrates include:
whole grains
legumes
beans
lentils
peas
potatoes
Fiber is found in many healthy carbs such as:
fruits
vegetables
whole grains
beans
legumes
Consuming fibrous, complex and simple carbs from naturally occurring sources like fruit may protect you from disease and may even help you maintain your weight. These carbs include more vitamins and minerals.
However, processed and refined carbohydrates are high in calories but relatively void of nutrition. They tend to make people gain weight and may even contribute to the development of obesity-related conditions, like type 2 diabetes and heart disease.
Daily intake
Carbohydrates should make up 45 to 65 percent of your daily calorie intake according to American dietary guidelines.
For a person eating a standard 2,000 calories a day, this means that carbohydrates might make up 900 to 1,300 of those calories. This figures out to around 225 to 325 grams each day. However, your carb intake will vary based on your individual needs.
