Why are carbohydrates important?

Carbohydrates are an essential part of our diet. Most importantly, they provide the energy for the most obvious functions of our body , such as moving or thinking, but also for the ‘background’ functions that most of the time we do not even notice 1. During digestion, carbohydrates that consist of more than one sugar get broken down into their monosaccharides by digestive enzymes, and then get directly absorbed causing a glycaemic response (see below). The body uses glucose directly as energy source in muscle, brain and other cells. Some of the carbohydrates cannot be broken down and they get either fermented by our gut bacteria or they transit through the gut without being changed. Interestingly, carbohydrates also play an important role in the structure and function of our cells, tissues and organs.

How do carbohydrates affect the body?

A diet needs to be nutritionally balanced, including the proper type and amount of carbohydrates. An increase or decrease in carbohydrates beyond the desired amount can affect both physiological and metabolic processes. An increase in simple carbohydrates may contribute to obesity, a disease that puts individuals at an even greater risk for further disorders such as cardiovascular disease. Carbohydrate intake also contributes to non-insulin-dependent diabetes (type 2 diabetes), a growing epidemic. However, foods rich in non-starch polysaccharides and low-glycemic foods protect against diabetes. Increased sugar consumption also contributes to the development of dental caries. [8][9]

Where does carbohydrate digestion occur?

Carbohydrate digestion begins in the mouth where salivary am ylase starts the breakdown. After breaking down throughout the digestive system, monosaccharides are absorbed into the bloodstream. As carbohydrates are consumed, the blood sugar levels increase, stimulating the pancreas to secrete insulin. Insulin signals the body’s cells to absorb the glucose for energy or storage. If blood glucose falls, the pancreas makes glucagon, stimulating the liver to release stored glucose.

What are the symptoms of carbohydrate malabsorption?

Carbohydrate malabsorption can present with symptoms of constipation, diarrhea, flatulence, and abdominal pain. It may occur as a result of congenital or acquired defects in enzyme metabolism or intestinal mucosa. Celiac and Crohn's disease are examples of secondary malabsorption. Small intestinal bacterial overgrowth (SIBO) can occur as a result of gastric bypass or gastric dysmotility disorders (chronic diabetes, scleroderma), resulting in compromise of the absorptive interface and severe malabsorption. On the other hand, lactose intolerance is a primary lactase deficiency. Lactase is the enzyme that breaks down lactose, a disaccharide, into monosaccharides glucose and galactose in the brush border of enterocytes. Lactase deficiency is the most common enzyme deficiency in the world.[10]  The most frequently used method for diagnosing carbohydrate malabsorption in the hydrogen exhalation test. In incomplete absorption, undigested carbohydrates enter the colon where hydrogen-gas-producing bacteria reside. The hydrogen gas (H2) level is measured on the first exhalation. Non-metabolized carbohydrates act as osmotic agents in the gastrointestinal tract, contributing to the symptoms of diarrhea and flatulence. Treatment of most carbohydrate malabsorption disorders includes avoidance of the associated mono- or disaccharide. [11][12]

What are the three macronutrients in the human body?

These molecules contain carbon, hydrogen, and oxygen atoms. Carbohydrates play an important role in the human body. They act as an energy source, help control blood glucose and insulin metabolism, participate in cholesterol and triglyceride metabolism, and help with fermentation. The digestive tract begins to break down carbohydrates into glucose, which is used for energy, upon consumption. Any extra glucose in the bloodstream is stored in the liver and muscle tissue until further energy is needed. Carbohydrates is an umbrella term that encompasses sugar, fruits, vegetables, fibers, and legumes. While there are numerous divisions of carbohydrates, the human diet benefits mostly from a certain subset.[1][2][3]

Healthy adult diets should include 45% to 65% carbohydrates as part of the daily intake, equaling about 200 g to 300 g per day. Carbohydrates contain about 4 kcal/ gram (17 kJ/g). Fiber is an important carbohydrate as well. Healthy adults should consume about 30 g per day of fiber, as it is found to reduce the risk of coronary heart disease, strokes, and digestive issues.
