1. Understanding Starch: The Basics
Starch is a complex carbohydrate that serves as a primary energy source for humans. It is composed of numerous glucose molecules linked together. When consumed, the body breaks down starch into glucose, which is then used for energy.
1.1. What is Starch?
Starch is a polysaccharide, meaning it consists of many glucose units linked together. These glucose units are arranged in two main forms: amylose and amylopectin. The ratio of amylose to amylopectin determines the properties of the starch, such as its digestibility and texture.
1.2. Types of Starches
There are two main types of starch:
- Amylose: This is a linear chain of glucose molecules. High amylose starches tend to be more resistant to digestion.
- Amylopectin: This is a highly branched chain of glucose molecules. High amylopectin starches are more easily digested.
1.3. Health Benefits of Starches
Starches, when consumed in moderation, offer several health benefits. They provide a sustained energy source, which is crucial for physical activity and cognitive functions. Resistant starches, in particular, promote gut health by feeding beneficial bacteria in the colon.
