A sheet of paper is composed primarily of cellulose, an indigestible plant fiber that provides no nutrition to humans. This means that when asking what is the nutritional value of a sheet of paper, the answer is effectively zero, and eating it can pose significant health risks.

Agar-agar, a gelling agent from red algae, is approximately 80% dietary fiber. This high fiber content is the key to understanding how our bodies process it, as humans are not able to fully digest or break down the complex carbohydrate. Instead, it passes through the digestive system largely intact, offering significant benefits to gut health.

Despite being a protein, research shows that fibrous, structural keratin is largely indigestible to humans. This reality often leaves many wondering: does keratin have nutritional value if we can't break it down and absorb it like other proteins?

Cellulose is the most abundant organic polymer on Earth, making up the tough cell walls of plants. So, is cellulose a carb or protein? The definitive answer is that cellulose is a complex carbohydrate, specifically a polysaccharide, composed of repeating glucose units.

According to the FDA, hydroxypropyl methylcellulose (HPMC) is classified as a Generally Recognized as Safe (GRAS) food additive, not because it is easily absorbed, but because the human body cannot digest it. This modified plant-based fiber passes through the digestive tract largely intact, offering unique functional properties in food and medicine rather than nutritional value.

Did you know that despite being a complex carbohydrate made of glucose, cellulose provides humans with zero calories? The primary reason is that humans lack the specific enzyme required to break down its unique molecular structure, making it indigestible for our bodies.

Rice husk, also known as rice hull, is a hard, fibrous coating that protects the grain of rice during its growth. Produced in large quantities as a byproduct of rice milling, historically it was consumed only in times of severe food scarcity. Modern nutritional science confirms that while rich in insoluble fiber, raw rice husk is not suitable for human consumption and poses several health risks.

According to the Mayo Clinic, dietary fiber refers to the parts of plant foods that the human body cannot digest or absorb. This indigestible component, often referred to as roughage or bulk, is a crucial part of a healthy diet, even though it is not broken down for energy.

Most traditional wax candies, like Nik-L-Nips, are made from food-grade wax, which is non-toxic but also indigestible, meaning your body cannot process it. So, is it bad to eat the wax from wax candy? The short answer is yes, you should avoid swallowing it.

Did you know that humans lack the crucial enzyme needed to break down cellulose, the main component of plant cell walls? This is why it is not a specific plant that cannot be digested, but rather certain components present in virtually all plant matter that remain largely undigested by the human body.
