Carbohydrates Carbohydrates are complex sugar molecules composed of more than two and up to ten sugar molecules are termed as oligosaccharides. More complex molecules made up of more than ten sugar molecules are known as polysaccharides. These complex structures are called carbohydrates. A good example of a carbohydrate is starch and cellulose.
Starch is composed of glucose monomers present in its cyclic structure. Cellulose is the main structural material of plants. It is also a polymer of glucose. Other such instances are insulin, glycogen, chitin, pectin, etc. Mostly carbohydrates are insoluble in water. They are not digested until broken down into simpler forms.
They are assimilated by the body into simple sugars which are then absorbed in the intestines. Finally, we may say that carbohydrates are polymers of simple sugars having different physical and chemical properties. Sugars are soluble in water while carbohydrates are insoluble in water. Sugars have a sweet taste while carbohydrates are not sweet. Sugars are readily digested in the body while carbohydrates have to be broken down into simpler molecules before being digested.
Difference Between Sugars and Carbohydrates. The Nutrition Facts on food labels can help. Although carbohydrates have just 4 calories per gram, the high sugar content in snack foods means the calories can add up quickly, and these "empty calories" usually have few other nutrients. Make good carbohydrate choices buy whole grains, fruits, veggies, and low-fat milk and dairy products , limit foods with added sugar, and encourage kids to be active every day.
And don't forget to be a good role model. Kids will see your healthy habits and adopt them, leading to a healthier lifestyle in childhood and beyond. Reviewed by: Jane M.

The two main forms of carbs are: simple carbohydrates or simple sugars : including fructose, glucose, and lactose, which also are found in nutritious whole fruits complex carbohydrates or starches : found in foods such as starchy vegetables, whole grains, rice, and breads and cereals So how does the body process carbs and sugar?
As the sugar level rises, the pancreas releases the hormone insulin, which is needed to move sugar from the blood into the cells, where the sugar can be used as energy The carbs in some foods mostly those that contain simple sugars and highly refined grains, such as white flour and white rice are easily broken down and cause blood sugar levels to rise quickly. Some carbohydrate-dense foods are healthier than others. Are Some Carbs Bad? And complex carbs: Break down more slowly in the body: Whole grains contain all three parts of the grain the bran, germ, and endosperm , whereas refined grains are mainly just the endosperm.
Whole grains give your body more to break down, so digestion is slower. When carbs enter the body more slowly, it's easier for your body to regulate them. Are high in fiber: High-fiber foods are filling and, therefore, discourage overeating. Plus, when combined with plenty of fluid, they help move food through the digestive system to prevent constipation and may protect against gut cancers.
Provide vitamins and minerals: Whole grains contain important vitamins and minerals, such as B vitamins, magnesium, and iron. What About Sugar? Consider these facts: Each ounce ml serving of a carbonated, sweetened soft drink has the equivalent of 10 teaspoons 49 ml of sugar and calories. You can find added sugars in different types of foods — even ones you may not think of as sweet, such as ketchup, bread, and canned baked beans.
That said, the main sources of added sugars are sugar-sweetened beverages, candy, desserts, ice cream, and sugary cereals Look at the nutrition facts panel on a food product to find out how many grams of added sugar it contains. This made it difficult to determine just how much added sugar you consumed. Many large food companies have already complied, making it easier to assess the added sugar content of products. The American Heart Association recommends that women and men get less than 25 grams and 38 grams of added sugar per day from their diet, respectively Getting more than these amounts makes it difficult to meet your nutrient needs while staying within your daily calorie limits Names for added sugars include:.
Labels list ingredients in descending order of predominance by weight, with the ingredients used in the greatest amount first, followed by those in smaller amounts. This means that if a product lists sugar as the first ingredient, you know it contains more sugar than anything else. You can identify added sugars by looking at the food label and reading the ingredient list. Limiting your calories from added sugar can help you meet your nutrient needs while staying within your daily calorie limits.
Yet, sugar is only one component of your diet. Research suggests that sugar only becomes problematic to your health when it comprises too much of your diet or if you get more calories than you need from sugar 10 , 33 , 34 , Besides, simple sugars are found naturally in a wide range of healthy foods, such as fruits, vegetables, and dairy.
These foods bring a variety of other important nutrients to your diet, such as vitamins, minerals, antioxidants, and fiber. Sugar is detrimental to your health when it makes up too much of your diet or you get excess calories from sugar. Therefore, limiting but not completely avoiding sugar — specifically added sugar — is worthwhile for your health. However, excess added sugar is linked to obesity and increased heart disease and cancer risk. You can find out how much added sugar a product has by looking at the nutrition facts panel or reading the ingredient list.
Despite the harmful effects added sugars can have on your health, you can eat them in moderation and as part of an overall healthy diet. Experts believe that excess sugar consumption is a major cause of obesity and many chronic diseases.
