1. Definition: Simple carbohydrates, also known as sugars, consist of one or two sugar molecules (monosaccharides or disaccharides).
2. Monosaccharides (Single Sugar Molecules):
   a. Glucose: The primary source of energy for cells. Found in fruits, honey, and corn syrup.
   b. Fructose: The sweetest natural sugar. Found in fruits and honey.
   c. Galactose: Found in dairy products and is a component of lactose.
3. Disaccharides (Two Sugar Molecules):
   a. Sucrose (Table Sugar): Composed of glucose and fructose. Found in sugar cane and sugar beets.
   b. Lactose (Milk Sugar): Composed of glucose and galactose. Found in dairy products.
   c. Maltose (Malt Sugar): Composed of two glucose molecules. Found in malted grains.
4. Sources: Fruits, honey, dairy products, table sugar, syrups, processed foods (candy, pastries, sugary drinks).

Complex Carbohydrates (Starches and Fibers): carbohydrates calculator

1. Definition: Complex carbohydrates are polysaccharides, meaning they consist of long chains of sugar molecules linked together.
2. Starches:
   a. Definition: Long chains of glucose molecules that the body breaks down into glucose for energy.
   b. Sources: Grains (wheat, rice, corn, oats), starchy vegetables (potatoes, sweet potatoes, corn), legumes (beans, lentils, peas).
3. Fibers:
   a. Definition: Non-digestible complex carbohydrates that provide numerous health benefits.
   b. Types:
   i. Soluble Fiber: Dissolves in water, forming a gel-like substance. Helps lower cholesterol and regulate blood sugar levels. Found in oats, beans, fruits, and vegetables.
   ii. Insoluble Fiber: Does not dissolve in water. Adds bulk to the stool, promoting regular bowel movements. Found in whole grains, vegetables, and wheat bran.
   c. Sources: Whole grains, fruits, vegetables, legumes, nuts, and seeds.

The Digestion and Metabolism of Carbohydrates: carbohydrates calculator Fueling the Body

Understanding how the body processes carbohydrates is crucial for making informed dietary choices.

Digestion: carbohydrates calculator

1. Mouth: The digestion of carbohydrates begins in the mouth with the enzyme amylase, which starts breaking down starches into smaller sugar molecules.
2. Stomach: The stomach’s acidic environment deactivates amylase.
3. Small Intestine: Pancreatic amylase further breaks down starches into disaccharides. Enzymes in the small intestine lining (sucrase, lactase, maltase) break down disaccharides into monosaccharides (glucose, fructose, galactose).
4. Absorption: Monosaccharides are absorbed into the bloodstream through the small intestine lining.

B. Metabolism: carbohydrates calculator

1. Glucose Uptake: After absorption, glucose enters the bloodstream. Insulin, a hormone produced by the pancreas, facilitates the uptake of glucose by cells for energy.
2. Energy Production: Inside the cells, glucose is used in cellular respiration to produce ATP (adenosine triphosphate), the primary energy currency of the cell.
3. Glycogen Storage: Excess glucose is stored as glycogen in the liver and muscles for later use.
4. Fat Conversion: If glycogen stores are full, excess glucose is converted into fat and stored in adipose tissue.
5. Fiber’s Role: Fiber, being non-digestible, passes through the digestive system, promoting gut health and regulating blood sugar levels.

IV. Good Carbs vs. Bad Carbs: Making Wise Choices
