Carbohydrates, often referred to as carbs, are vital nutrients essential for maintaining daily energy levels. Insufficient intake can lead to fatigue, low blood pressure, decreased blood sugar levels, and increased cravings. Explore the significance of carbs for health in this Mytour Blog article.
Exploring Carbohydrates: Origins and Significance
Carbohydrates, or carbs for short, represent one of the three essential macronutrients responsible for providing energy to the body, alongside proteins and fats. Derived from the chemical composition, carbohydrates consist of carbon, oxygen, and hydrogen. They encompass starches, sugars, and fibers found in various fruits, vegetables, and dairy products or derivatives.
According to nutrition experts, a deficiency in carbohydrates can result in feelings of fatigue, lack of energy, reduced appetite, and disruption of daily activities. Therefore, the average adult male requires approximately 250–270g of carbs per day, while adult females need around 225–250g of carbs per day to efficiently carry out activities and achieve optimal productivity in their work.

Fundamentally, carbohydrates are divided into two main types:
- Simple Carbohydrates (Monosaccharides, Disaccharides): This carbohydrate group contains one or two sugar molecules. For example, fructose (found in fruits), galactose (found in dairy products), sucrose (table sugar), lactose (milk), and maltose (found in beer, vegetables). Additionally, simple carbs are also found in candies, soda, soft drinks, syrups, etc. However, these foods are often made from refined sugars, lacking in fiber, vitamins, and minerals beneficial for health.
- Complex Carbohydrates: This group consists of carbohydrates with a structure of three sugar molecules or more. Complex carbs are typically found in foods rich in good carbohydrates such as lentils, peanuts, potatoes, corn, celery, grains, whole-grain bread, etc. According to nutrition experts, simple carbs are absorbed faster than complex carbs, so they can quickly provide energy to the body. However, consuming too many simple carbs can increase blood sugar levels, leading to heart disease and diabetes.
The Role of Carbohydrates in Health
Understanding the role of carbohydrates is crucial to recognizing their importance in the body. Below are the significant roles of carbohydrates with the body and health that you should know:
Providing Energy to the Body
The primary role of carbohydrates is to provide energy to the body for performing daily activities. According to scientific research, when carbohydrates enter the body, they are metabolized into glucose. After a complex process, glucose is transported into the bloodstream to provide energy to the cells in the body.
Supporting Workout Processes
Carbohydrates are an essential source of energy to maintain health and enhance effectiveness during workouts. If lacking in carbohydrates, you may feel fatigued, experience reduced motivation, and have decreased workout capacity. Therefore, experts recommend having a light meal before exercising, approximately 1–3 hours prior, which can include a combination of carbs and protein such as oatmeal, peanut butter, Greek yogurt, or a mix of nuts and raisins.

Excess glucose is stored in the body as glycogen (mainly in the liver). If there's too much glucose, it's converted into fat. This storage process helps maintain energy levels between meals. However, the amount of stored glucose in the liver only provides enough energy for about a day.
Some Carb-Rich Foods
Here are some suggestions for the most carb-rich foods available today that you can choose to supplement your daily diet and balance your body's nutrients.

Carb-Rich Foods (Source: Internet)Consequences of Excessive Carb Consumption
Consuming too many carbohydrates can lead to headaches and a rapid increase in blood sugar. When this happens, the body will produce more insulin to regulate blood sugar levels back to a safe range, and excess glucose will be converted into fat. This is detrimental to health, especially when the body is overweight or obese, as it increases the risk of diabetes and other diseases.
Effects of Insufficient Carb Intake
If your diet lacks sufficient carbohydrates, it can lead to constipation due to a deficiency in fiber and nutrients. In this situation, you need to supplement protein and fats to provide energy for your body.
Considerations When Adding Carbs
Once you understand the role of carbs, it's important to note the following when adding carbs to your daily intake to avoid affecting your health:
- Nutrition experts advise consuming a maximum of about 10-15% simple carbs and 85-90% complex carbs to prevent blood sugar spikes and the onset of diabetes.
- People with diabetes need to be cautious about their carb intake because their bodies can no longer regulate blood sugar levels safely. Diabetic patients should consult their doctors to understand how to manage their condition effectively.

A low-carb diet is based on the principle of limiting starch consumption (carbohydrates), such as carbs found in grains, vegetables, and fruits, while emphasizing foods high in protein and fats. Digesting protein requires the body to use stored calcium, thereby increasing the burden on the kidneys. Additionally, the body needs to consume more saturated fats to replace carbs, which is not beneficial for long-term health.
Some individuals who may need to supplement carbs include:
Those who often feel tired, stressed, cold, or have poor sleep quality.
Individuals who struggle to gain muscle despite diligent exercise.
Those experiencing a plateau in weight loss.
Women with irregular menstrual cycles or menstrual cramps.
According to scientific research, an adult needs to consume about 2500 calories for all activities throughout the day. Of these, a reasonable amount of calories provided by carbohydrates is 50-60%, equivalent to 1250-1500 calories. Therefore, you should plan your menu to consume only 312-375g of carbs per day, as 1g of carbs releases 4 calories.
Hopefully, the valuable information shared by Mytour has helped answer your question what are carbs? Carbohydrates are an important source of energy for the body, enhancing metabolic processes and maintaining vitality. However, you need to balance the amount of carbs to ensure optimal health and body condition.
