Vitamins are an important part of food and are absorbed through the small intestine. Vitamins are grouped based on how your body absorbs them. Water-soluble B-complex and C vitamins dissolve in water prior to absorption. Fat-soluble vitamins -- A, D, E and K -- dissolve in fat to be absorbed and stored for later use.

These vessels transport fat to the veins of your chest, and the blood carries fat to be stored in adipose tissue throughout your body. Proteins Protein is found in meat, eggs, dairy products, fish, nuts and beans. Before your body can use protein to build and repair tissues, the large molecules of protein must be digested by enzymes into small molecules called amino acids. Digestion of protein begins in your stomach with the aid of gastric juices.

Most lipids that you consume in your diet are fats. Some digestion occurs in your mouth and the stomach, but most takes place in the small intestine. Bile is produced by your liver, stored and released in your gall bladder and emulsifies fat globules into smaller droplets.

As glucose is removed from the blood stream, insulin levels go down and your cells start using fat for fuel instead of glucose. This is why you can go for long stretches – overnight, for example, when you’re sleeping, without eating. Your cells rely on fat for fuel. There are two types of body fat: fatty acids and triglycerides. Fatty acids are small enough to move in and out of cells and be used as fuel for cells. Fat is stored inside fat cells as triglycerides, three fatty acids bound together.

With less estrogen in the body, LPL can pull more fat into fat cells and store it there. The HSL enzyme works to make fat cells leaner by breaking down triglycerides into fatty acids that then can leave the fat cell and be used as fuel by other cells. So the higher HSL levels, the more fat we break down and burn. Insulin reduces HSL enzyme levels, which stops triglycerides from being broken down and means more fat is stored in fat cells.

High-fructose corn syrup is 55% fructose, 42% glucose, and 3% other carbohydrates. One important fact about fructose: it’s the carbohydrate your body converts to fat most easily. When you digest high-fructose corn syrup, much of the glucose in it ends up in the blood stream, raising your blood sugar levels.

While you need some cholesterol in your body, everything you need is produced in your liver. Any additional cholesterol you consume either builds up on artery walls -- a condition called atherosclerosis -- or is broken down and excreted. Types of Fat. Some types of fats are better for you than others. Limit saturated and trans fats in your diet.

Fats are an essential part of your diet; they help regulate body temperature, aid in hormone production, help your body absorb fat-soluble vitamins and several other functions. In order for your body to utilize fat for these functions, it has to be digested into a simpler, less complex molecule. During digestion, fats are broken down into fatty acids or cholesterol and absorbed into the bloodstream. Video of the Day

Nutrients are important substances that allow your body to perform required daily activities. Carbohydrates, fats and proteins are the major nutrients your body needs for growth, repair, movement and maintaining homeostasis. These macromolecules are broken down and absorbed into the body at different rates and into specific forms as they travel through the organs in your digestive system. Carbohydrates Carbohydrates are your body's preferred energy source and are found in the forms of starch, sugar and fiber.

As you digest carbohydrates, they go into the blood stream as glucose. To keep blood sugar levels under control, insulin signals the cells in your body to take in glucose from the blood stream. The cells use some of glucose for energy and store some for later use.
