The body converts carbohydrates into glucose to provide the energy they need to function, including fiber, starches, and sugars. Compared to simple carbohydrates (sugars), complex carbs in fruits, vegetables, and whole-grain items are less likely to cause a surge in blood sugar. Ketogenic diets, for example, might be rich in fat. Many people are confused about carbohydrates, but it is vital to remember that eating carbohydrates from nutritious meals is more crucial than adhering to a rigid diet restricting or counting the grams of carbohydrates ingested.

Carbohydrates: What Are They?

  • Along with proteins and lipids, carbohydrates are one of the three macronutrients the body needs daily.

  • Carbohydrates come in three primary categories: starches, fiber, and sugars. Complex carbohydrates are frequently used to describe starches.

  • They can be found in grains, legumes, and starchy vegetables like potatoes and maize.

  • Sugars are the type of "simple carbohydrates" mentioned. Natural sugars may be found in honey, milk, fruits, and vegetables.

  • Processed meals, syrups, sugary beverages, and desserts include added sugars.

  • Carbohydrates are converted to glucose or blood sugar by the intestines.

  • Glucose is absorbed by the bloodstream and used by the body as fuel.

  • Blood sugar levels are impacted by how many carbohydrates people eat.

  • Blood sugar levels might rise when one consumes a lot of carbohydrates. Hyperglycemia, or high blood sugar, increases the likelihood of developing diabetes.

  • Some people who fail to consume enough carbohydrates get hypoglycemia or low blood sugar.

Why Do Human Beings Require Carbohydrates?

The body uses carbohydrates as a primary energy source to power the kidneys, heart, brain, muscles, and central nervous system. As an illustration, fiber is a carbohydrate that promotes healthy digestion, makes one feel full, and lowers blood cholesterol levels. When people fail to consume enough carbohydrates, the body might store additional carbohydrates in their muscles and liver for use later. A diet deficient in carbohydrates leads to headaches, weakness, drowsiness, vomiting, constipation, bad breath, and vitamin and mineral deficiencies.

What Are the Forms of Carbohydrates?

Complex Carbohydrates:

The chemical composition of a meal and the rate at which the body breaks it down decide whether it is a complex or simple carbohydrate. Complex carbohydrates are less likely to produce blood sugar. They also provide fiber, vitamins, and minerals that the body needs. Although people may be accustomed to hearing about "good carbohydrates," it might be wiser to think of them as "healthy carbohydrates."

Simple Carbohydrates:

A surplus of simple carbohydrates might make people gain weight. They can also make people susceptible to high cholesterol, diabetes, and heart disease. White bread, pastries, sodas, and other highly processed or refined meals are among the less healthy carbohydrates. These foods have simple carbohydrates, which can make it difficult to lose weight and can increase the risk of diabetes and heart disease.

What Are the Types of Carbohydrates?


Complex carbohydrates include starches. Although not all starches belong to this category, many do. The body processes complex carbohydrates more slowly. Consequently, satiety lasts longer, and blood sugar levels stay steady. Starchy carbohydrates can be found in:

  • Legumes and beans, including kidney beans, black beans, chickpeas, and lentils.

  • Fruits include melons, berries, and apples.

  • Foods from whole grains include oatmeal, whole-wheat bread, and brown rice.

  • Veggies include potatoes, maize, lima beans, peas, and others.


Fruits, vegetables, and whole-grain goods are plant-based foods that include fiber. There is no fiber in any animal products, including dairy and meat. A complex, beneficial carbohydrate is fiber. The human body cannot break down fiber. As it passes through the intestines, most of it stimulates and aids in digestion.

Additionally, fiber controls blood sugar and reduce cholesterol, and prolongs feelings of fullness. According to experts, adults should ingest 0.89 to 1.07 ounces of fiber daily. The majority of us only get half of that.

  • Legumes and beans, such as pinto beans, black beans, chickpeas, and lentils, are among the foods high in fiber.

  • Fruits, particularly those having edible skins (apples, peaches, and berries) or seeds.

  • Among the many types of nuts and seeds are almonds, peanuts, walnuts, seeds from pumpkins, and the seeds of sunflowers.

  • Whole-grain foods include cereal, oats, quinoa, and brown rice.


One kind of simple carbohydrate is sugar. The human body readily metabolizes simple carbohydrates. Blood sugar levels quickly rise and then fall as a result. One can have a sudden rush of energy after eating anything sweet, followed by a sensation of exhaustion. Two varieties of sugar exist:

  • Natural sources of sugars include milk and fresh fruit.

  • Added sugars, including soda, canned fruit, candy, and juice. Sweets include things like ice cream, bars of candy, and bakery items.

The way the human body handles glucose is the same. It is unable to differentiate between naturally occurring and added sugars. However, meals with natural sugars include vitamins, minerals, and occasionally fiber. Sugar consumption must be restricted to maintain appropriate blood sugar levels. Additionally, sweet foods and beverages frequently have higher calorie counts that may lead to weight gain. Meals like white flour, sweets, candies, juices, fruit drinks, soda pop, and sweetened beverages should be avoided, as well as processed meals and foods with added sugar.

  • There is no established daily carbohydrate recommendation.

  • The quantity that is good for individuals depends on age, gender, medical issues, degree of exercise, and weight objectives.

  • Some people with diabetes find that counting carbohydrates helps them control their blood sugar.

  • To encourage weight reduction, some people reduce their carbohydrate consumption.

  • The Atkins diet and the ketogenic (keto) diet are two well-known low-carbohydrate diet plans.

  • Long-term adherence to stringent dietary restrictions can take time and effort. Significant levels of animal fat and oils are present in several carb-restricted diets.

  • Experts are still trying to determine the healthfulness of low- or no-carbohydrate diets.

  • Before attempting a low- or no-carb diet, consult a physician.


The type of carbohydrate one chooses to consume is crucial since specific sources are healthier than others. The kind of carbohydrates in the diet is more significant than their high or low quantity. Eating reasonable amounts of carbohydrates that are whole grains and high in fiber can be healthful. Reduce refined carbohydrates in the diet and replace them with lean protein, whole grains, fruits, vegetables, legumes, and fats from vegetable sources. Make a habit of including as many healthy carbohydrates as possible while lowering the overall carbohydrate content from 55 percent of calories to approximately 40 percent.
