The body uses three main nutrients to function— carbohydrate, protein, and fat. These nutrients are digested into simpler compounds. Carbohydrates are used for energy (glucose). Fats are used for energy after they are broken into fatty acids.

As we digest food, our body transports and utilises various vitamins, minerals, protein, carbohydrates and fats at different points along the digestive tract. The absorption process begins around 3-6 hours after eating.

Carbohydrates are your body's main source of energy: They help fuel your brain kidneys heart muscles and central nervous system. For instance fiber is a carbohydrate that aids in digestion helps you feel full and keeps blood cholesterol levels in check.

Sugars mostly make up carbohydrates. They get their name from their chemical composition: carbon, hydrogen, and oxygen (thus carbo-hydrate). Generally, the length of the sugar chain making up the carbohydrate can determine the rate of digestion and absorption.

(a) Carbohydrates are one of the main types of nutrients found in food. They are the most important source of energy for the body of many organisms, including humans. Carbohydrate provides about 4 kcal per gram and is the energy that is used first to fuel muscles and the brain.

Food that we eat gives us energy to go through our day. It gives us energy by providing energy to the cells inside our body. Carbohydrates in food are used first. When they are all used up, the body then uses fats, and then proteins as energy sources.

Slow carbs, as the name suggest release energy slowly into the body. Fast carbs release energy at a much higher pace and get used quickly. Higher the GI level, quicker is the delivery of sugar and energy in the body.

They also come in a variety of forms. The most common and abundant forms are sugars, fibers, and starches. Foods high in carbohydrates are an important part of a healthy diet. Carbohydrates provide the body with glucose, which is converted to energy used to support bodily functions and physical activity.

When carbs are digested, they're turned into glucose. Glucose is the main source of energy for your body. Simple carbs can provide a quick burst of energy, but complex carbs will provide energy for your body for a longer period of time because they release the sugar into your bloodstream more slowly.

1. Introduction. Alongside fat and protein, carbohydrates are one of the three macronutrients in our diet with their main function being to provide energy to the body. They occur in many different forms, like sugars and dietary fibre, and in many different foods, such as whole grains, fruit and vegetables.

Nutrients of Human Metabolism Carbohydrates, lipids, and proteins are the major constituents of foods and serve as fuel molecules for the human body.

For example, a food that contains 20 grams (g) of total carbs and 10 g of dietary fiber has 10 g of net carbs. This final number, 10 g, is the amount of carbohydrates the food contains that the body can digest into glucose.

Carbohydrate digestion begins in the mouth with the mechanical action of chewing and the chemical action of salivary amylase. Carbohydrates are not chemically broken down in the stomach, but rather in the small intestine.
