3 Major Types of Carb Foods
Carbohydrates are an important macronutrient that provides us with energy in the form of calories.

Carbohydrates are one of three macronutrients (the other two being protein and fats); they are one of three food groups that people should consume in substantial amounts to maintain optimal health.

Carbohydrates include starch, fiber, and sugars present in a wide range of foods, including grains, vegetables, fruits, and dairy products.

3 major types of carbohydrates

Three major types of carb foods include:

  1. Sugar
    • Naturally occurring sugars in fruits, vegetables, and milk/milk products
    • Refined sugars in sweet foods such as pastries, syrups, cookies, and soft drinks
  2. Starch
    • Potatoes
    • Beans and lentils
    • Corn
    • Peas
    • Grains, such as rice, oats, and wheat
  3. Fiber
    • Whole-grain foods, such as whole-grain bread, cereal, and pasta
    • Vegetables, particularly leafy greens and fruits
    • Nuts, such as peanuts, walnuts, and almonds
    • Seeds

What are carbohydrates?

Carbohydrates provide us with energy in the form of calories. When you consume carbohydrates, your body converts them into a type of sugar known as glucose, which increases your blood sugar levels and provides you with more energy.

Carbohydrates are often measured in grams. The average adult should consume about 135 grams of carbohydrates per day; however, each person should have their own carbohydrate target depending on factors such as physical activity, age, weight, and underlying health issues.

Are carbs good for your health?

The type of carb that you include in your diet may determine if your diet is healthy or unhealthy. In the field of food science, simple and complex carbohydrates are the two basic groups.

  1. Simple carbohydrates or bad carbs (monosaccharides and disaccharides)
    • Highly processed foods such as refined pasta or dough, white bread, white rice or pastries, and sugary drinks are examples of bad or simple carbohydrates. 
    • Because they digest rapidly and don't make you feel as full, these carbohydrates might cause overeating and weight gain.
    • Simple carbs are absorbed faster from the gut, giving you a brief, immediate spike of sugars and energy but making you feel hungry again sooner.
  2. Complex carbohydrates or good carbs (polysaccharides)
    • Have various nutrients and fiber and are rich in vitamins and minerals
    • Complex carbohydrates are absorbed more slowly than simple carbohydrates, resulting in longer energy and a longer feeling of fullness.
    • Examples of complex carbs include fruits, vegetables, nuts, lentils, whole grains, and beans.

The types of molecules that make up carbohydrates further distinguish them from one another.

  • Monosaccharides, which comprise glucose, galactose, and fructose, are the most prevalent and basic.
  • Disaccharides contain two monosaccharides linked together, for example, lactose and sucrose.
  • Polysaccharides are the most complex and contain several monosaccharides linked together. Their examples include starch and dietary fiber.

QUESTION

According to the USDA, there is no difference between a “portion” and a “serving.” See Answer

What foods contain healthy and unhealthy carbs?

Healthy carbohydrates not only are empty calories but also provide additional nourishment. 

The following are foods that are a component of a healthy diet and include good carbohydrates:

  • Beans
  • Lentils
  • Milk
  • Yogurt
  • Corn
  • Berries
  • Oats
  • Apples
  • Brown rice
  • Whole wheat pasta
  • Popcorn

Use little to no butter on your popcorn and sweet potatoes if you're attempting to lose weight. For sweetness, add fresh berries to your oatmeal in place of sugar. Additionally, although whole wheat pasta and brown rice are healthier options, you should still practice portion control while eating.

Carbohydrates that have had their natural nutrients stripped away for flavor or processing are considered bad carbs.

Limit or eliminate bad carbs such as:

  • White rice
  • Enriched pasta
  • Sweetened yogurt
  • Breakfast cereals
  • Refined sugars
  • Sugary beverages including sodas and juices
  • Sweetened nut butter
  • Pastries
  • Cookies

What are the advantages and downsides of including carbs in the diet?

Carbohydrates are found in many foods; however, some foods are more nutrient-dense than others. Choose carbohydrate foods that contain other nutrients. This ensures that the body receives not only energy but also other nutrients that it requires to function.

Five advantages of including carb foods in your diet

  1. Source of energy
    • One gram of carbohydrate contains approximately four calories, and carbs must account for 900 to 1,300 calories of your total 2,000-calorie diet. 
    • They give the energy that is required for optimal organ function.
  2. Prevent ketosis
    • A low-carbohydrate diet causes your body to rely on fats and proteins for energy, which can result in ketone breath and a bad taste in your mouth. 
    • Furthermore, not all organs and cells can use fats and proteins for energy as glucose sources.
  3. Promote weight loss
    • Complex carbs increase satiety and help you reach your weight loss goals faster. To achieve the best results, choose alternatives such as quinoa and salads and snack on whole fruits rather than juices or jams.
  4. Benefit athletes
    • Although protein is necessary for muscle growth, carbohydrates are required to provide athletes with a consistent energy source, especially during intense training sessions.
    • It provides them with enough glucose and prevents muscle fatigue.
  5. Improve digestion
    • Complex carbohydrates or fiber aid in proper digestion by modulating the gut microbiome. They prevent constipation and promote overall gut health.

Side effects of excess carbohydrates in the diet

Although carbohydrates are beneficial to your overall health, an excess of them, particularly simple carbohydrates or sugars, can cause:

What is a low-carb diet?

A low-carbohydrate diet is including food in your diet that has fewer carbs. There is no hard and fast rule for how few carbs should be consumed because it varies depending on the individual and diet.

A low-carbohydrate diet limits carbohydrate consumption while emphasizing protein and fat intake. Most low-carb diets allow carb consumption between 50 to 100 grams a day. Very-low-carb or keto diet may limit carb consumption to less than 50 grams a day.

There are several types of low-carb diets based on the types and amounts of carbs consumed. However, these common foods are part of the low-carb diet:

  • Lean meat
  • Eggs
  • Fish
  • Leafy vegetables
  • Healthy fats
  • Whole grains, fruits, dairy products, lentils, and beans (in limited quantities)

These foods are high in protein and fat and low in carbohydrates. Although scientific evidence suggests that low-carb diets have significant health benefits, they may not be the healthiest option for everyone.

Bottom line

The amount of carbohydrates a person should consume varies according to their age, gender, size, and activity level, making each person unique. In general, half of your plate should be fruits and vegetables, and the other half should be whole grains and protein. Include healthy fats in moderation.

Carbohydrates from fruits, vegetables, grains, legumes, and dairy will account for roughly half of your total calories for the day if you do this.

Carbohydrates are essential nutrients for the body and should not be avoided. Some carbohydrate-rich foods are high in fiber, vitamins, and minerals. 

Carbohydrates in their natural, fiber-rich form, as opposed to processed and refined carbs, are generally healthy and do not cause ill effects such as unhealthy weight gain. Prioritize vegetables, fruits, legumes, and whole grains when it comes to carbohydrate intake.

A well-balanced diet rich in complex carbohydrates, along with adequate sleep and physical activity, is more likely to keep a person healthy than focusing on removing a specific nutrient from the diet.
