Are Carbs Bad For You? The Truth About Carbohydrates.

"Carbs make you fat! Don't eat carbs...just have a low carb diet!"


Such claims were made by diets and experts alike beginning in the 90's when special attention was given to low carb or carb free diet. Remember the Atkins diet? Yes, it's still around and followers adhere to low carb diets (without regard to fats or other group intakes).


The purpose of today's post is to educate you that not ALL carbohydrates are bad and that, if taken in moderate amounts, they can help you achieve your goals.


Premise: Not all carbohydrates are created equal!


What are carbohydrates?
Carbohydrates, also referred to as "carbsare "one of the main types of nutrients. They are the most important source of energy for your body. Your digestive system changes carbohydrates into glucose (blood sugar). Your body uses this sugar for energy for your cells, tissues and organs. It stores any extra sugar in your liver and muscles for when it is needed." (U.S. National Institute of Health - http://www.nlm.nih.gov/medlineplus/carbohydrates.html)


Why are carbohydrates needed?
Carbohydrates are the human body's source of energy. Carbs are to humans as gasoline is to a car, in other words, your body cannot function without them.


Carbohydrates are broken down into glucose before they can enter the bloodstream. Excess carbs are stored as glucose in your liver and this is referred to as glycogenGlycogen is used to fuel workouts and other intense activities.


Carbohydrate Classifications
Carbohydrates are classified in two types: simple and complex.


Simple carbohydrates are "sugars—including dextrose, fructose, lactose, maltose, sucrose, white sugar, corn syrup, honey, and turbinado sugar—that are quickly and easily absorbed into the bloodstream." (http://medical-dictionary.thefreedictionary.com/simple+carbohydrates)


Examples of foods containing simple carbohydrates include many processed or refined foods including; white bread, soda, white sugar, corn syrup, fruit juice, cake, most packaged cereals, and candy to list a few.


Complex Carbohydrates are "polysaccharides; nutritional compounds composed of multiple monosaccharide (simple sugar) building blocks. Complex carbohydrates include starches, glycogen, and cellulose." (http://medical-dictionary.thefreedictionary.com/complex+carbohydrates)


Example of foods containing complex carbohydrates include whole grain food items, lentils, many vegetables, brown rice, low fat yogurt, and more.


For more examples of each, refer to: http://howtothinkthin.com/instincts2.htm


Which type is better? Why?
Complex Carbohydrates are the better carbohydrate. 


The reason being complex carbohydrate foods have been shown to enter the blood stream gradually and trigger only a moderate rise in insulin levels, which stabilizes appetite and results in fewer carbohydrates that are stored as fat. Unrefined or ‘whole grain’ carbohydrates found in products like brown rice, whole wheat pasta and bran cereals are digested slowly. They contain vitamins, minerals and fiber which promote health. Fiber and nutrient-rich vegetables, fruits and beans which are carbohydrates also have many important functions for the body and are important for good health. (http://www.sparkpeople.com/resource/nutrition_articles.asp?id=590)


Simple carbohydrates cause a spike in blood sugar levels and then a crash which can elevate the appetite to want more food and increase the risk of fat storage.


It should also be noted that complex carbs provide an excellent source of fiber (which promotes digestive health.)
