What is difference between simple and complex sugar ?
Carbohydrates can be broken up into two different groups: simple and complex. Simple carbohydrates general comprise what we know as sugars, while complex carbohydrates consist of starches and fiber.
The two types of carbs also differ in their molecular structures. Simple carbohydrates comprise just one or two sugars, like fructose, lactose, and sucrose. Single sugars are known as monosaccharides, while carbs with two sugars are called disaccharides. Complex carbohydrates are polysaccharides, meaning they contain three or more sugars.
The different molecular structures have a huge effect on how the carbs are digested. Simple carbs are much easier for the body to break down and absorb, leading to quicker bursts of energy, while complex carbs take longer to digest, allowing for a more sustained flow of energy over a longer period of time. Simple carbs also tend to cause sudden spikes in blood sugar, sugar highs, and eventual crashes.
