Difference Between Simple and Complex Carbohydrates
May 15, · Examples of such foods include: candy. sugary drinks. syrups. table sugar. fruit juice concentrate. products with added sugar, such as baked goods or some cereals. Author: Aaron Kandola. Jan 15, · Carbohydrates are sugars that come in 2 main forms – simple and complex. This is also referred to as simple sugars and starches. The difference between a simple and complex carb is in how quickly it is digested and absorbed – as well as it’s chemical structure. Most carbohydrates can be broken down by digestion into glucose and these are the carbohydrates we shall look at in this article.
Simple and complex carbohydrates are the two forms of carbohydrates which are consumed zre animals. Carbohydrates are also called starch or sugars. Carbohydrate is a biological molecule composed what are simple and complex carbohydrates carbon C ximple, hydrogen H and oxygen O atoms, with a hydrogen to oxygen atom ratio of The main difference between simple and complex carbohydrates is that simple carbohydrates are quickly digested and absorbed by the body whereas complex carbohydrates take time to be digested.
An adult man should consume less than 70 g of sugars per day and an adult woman should consume less than 50 g of sugars per day. Simple carbohydrates are carbohydrates that contain single monosaccharide units. They are found in natural food sources such as milk, fruit, and vegetables.
Simple sugars give food a sweet taste. The blood glucose levels are elevated by simple sugars since they are easy to digest and are readily absorbed. Monosaccharides and arre are two types of simple carbohydrates. Monosaccharides include glucose, galactoseand fructose. Glucose is a simple sugar that circulates in the bloodstream of animals. Glucose is produced by plants during photosynthesis. Galactose occurs in milk in the form of lactose.
Galactose is less sweet than glucose and fructose. Fructose is fruit sugar and mainly occurs in plants. A glucose molecule is shown in figure 2.
Disaccharides include sucrose, lactose, and sjmple. A sucrose molecule is made up of glucose and fructose molecules. Sucrose is the organic compound which is transported by the phloem. Lactose is made up of a glucose and a galactose aee. Maltose is made up of two glucose molecules. It is produced in the breakdown of starch by amylase. Complex carbohydrates are polysaccharides which are made up of hundreds or thousands of monosaccharide units. They are also called polysaccharides.
Complex carbohydrates are more slowly digested and take time to absorb to the body. Green vegetables, starchy vegetables such as potatoes and corn, peas, lentils, beans, whole grain and food produced by the whole grain are composed of complex carbohydrates. Some sources of complex carbohydrates are shown in figure 3. Figure 3: Complex How to stop your nose from itching. Usually, the whole grain food raises blood sugar levels more slowly than simple carbohydrates.
However, higher levels of polysaccharides may increase the blood glucose levels considerably. Simple Carbohydrates: Simple carbohydrates refer to the carbohydrates that contain single monosaccharide units.
Complex Carbohydrates: Complex carbohydrates refer to a polysaccharide that is made carbohyfrates of hundreds or thousands of monosaccharide units.
Simple Carbohydrates: Simple carbohydrates are easy to digest. Complex Carbohydrates: Complex carbohydrates take carbohydfates to digest. Simple Carbohydrates: Monosaccharides and disaccharides are types of simple carbohydrates.
Complex complsx Polysaccharides such as starch are complex carbohydrates. Simple Carbohydrates: Simple carbohydrates contain sweetness. Complex Carbohydrates: Complex carbohydrates are less sweet than simple carbohydrates. Simple Carbohydrates: Simple carbohydrates quickly raise blood glucose levels. Complex Carbohydrates: Complex carbohydrates slowly raise blood glucose levels.
Simple and complex carbohydrates are the two forms of carbohydrates consumable by animals. Simple smiple are monosaccharides and disaccharides. Complex carbohydrates are polysaccharides such as starch. Simple carbohydrates are cojplex digestible and absorbable by the body. But, complex comppex take time for digestion. Therefore, the main difference between simple and complex carbohydrates is their complexity. Hultin, Ginger. Figure 1: How to cancel a sent text message on iphone. Figure 2: Glucose.

Keeping track of carbohydrates in the diet is an important part of managing type 2 diabetes. It's also helpful to have some knowledge of the difference between the two types of carbohydrates: simple carbs that are found in everything from table sugar to fruit, and complex carbs, or starches, that occur in foods such as whole grains and starchy vegetables like sweet potatoes.
Each type of carb impacts blood glucose levels somewhat differently. Carbohydrate is one of the three macronutrients in food that provide fuel for the body to function properly. The other two are protein and fat. During digestion, all three are broken down into the elements the body can use for energy: Protein is reduced to amino acids and fat is reduced to fatty acids , both of which are then stored for future use. Carbohydrates, on the other hand, are broken down into glucose sugar which, after a quick stop in the liver, enters the bloodstream and is immediately available to be taken up by cells for energy.
This is why eating carbs can affect blood sugar levels so quickly and dramatically. It's also why it's so important for people with type 2 diabetes to keep tabs on the carbs they eat. In this disease, either the pancreas does not produce enough of a hormone called insulin that regulates blood glucose levels or the body has become resistant to the effects of insulin. In both cases, glucose can build up in the bloodstream.
Simple carbohydrates are, as the name implies, simple structures. In chemical terms, they're small molecules consisting of a single monosaccharide or of two monosaccharides linked together—this is called disaccharides. Glucose, the type of sugar the body and brain use for energy, is a monosaccharide, as are fructose and galactose.
The disaccharides include lactose, sucrose, and maltose. Simple carbs are fairly easy for the body to digest. Most of these carbs are processed in the small intestine, where enzymes break them down into individual components that then pass through the intestinal walls into the bloodstream to be used for energy.
Any sugar that isn't used right away is converted to fat and stored. This is why eating foods with lots of added sugar can contribute to weight gain. Many foods containing naturally occurring simple carbohydrates are rich sources of vitamins, minerals, antioxidants, fiber, and other nutrients.
These foods can—and should—be a part of a diabetes-friendly diet. Examples include:. Fruits are valuable sources of vitamins, minerals, antioxidants, and fiber, as are vegetables and grains.
By the same token, dairy products offer protein, calcium, and vitamin D. However, not all simple sugars are processed at the same rate. For instance, because whole fruit contains fiber, the fructose it contains is digested and absorbed more slowly than, say, sucrose, and may have a less dramatic effect on blood glucose levels. The added sugars in many processed foods are also simple carbs—think sugary drinks, syrups, cookies, and jellies.
These tend to be "empty calories" with little nutritional value, and they more easily lead to weight gain and health problems like heart disease. Complex carbohydrates, known as oligosaccharides and polysaccharides, are made up of longer, more complex chains of sugar molecules. It takes the body longer to digest complex carbs than to process simple carbs.
Some complex carbohydrate foods contain fiber, vitamins, and minerals and take longer to digest. This means they have a less immediate impact on blood sugar, causing it to rise more slowly. Certain complex carbs are better choices than others. Note that all of these foods are excellent sources of fiber. Fiber helps keep blood sugar levels from spiking too high, helps regulate cholesterol levels, and is important for intestinal health.
With complex carbs, it's best to avoid or limit grains that have been refined and processed foods made from refined grains. The part of the kernel that's left, the endosperm, is starchy and has less fiber and nutrients. Sometimes vitamins and minerals are added back into refined grains in which case they typically are labeled as enriched , but this is no substitute for naturally occurring grains.
Processed foods made from refined grains include:. Note that many of these foods are also sources of added sugar, further making them less than ideal for managing blood glucose. How different people respond to specific types of carbs, and even to individual foods, can vary widely. This is one reason there's no such thing as a standardized treatment protocol for diabetes.
That said, when planning meals and snacks , it's generally advisable to focus on getting most of your carbohydrates—both simple and complex—from natural, unrefined, and unprocessed sources, like fresh fruits and vegetables, whole grains and products made from whole grains, low-fat dairy products, and legumes.
