Many people have a love-hate relationship with carbs. As in, loving to eat cakes, cookies, pasta, and chips, but hating what these tasty foods do to our moods, bodies, and waistlines.

Nutritional experts are also divided. Some diets completely eliminate carbohydrates while others tout moderation and filling up on more wholesome carbs like legumes, whole grain breads, and vegetables and fruit.

So, where’s the middle ground? The answer seems to be eating less bad—and more good—carbs, since your body does need a daily amount that it can process into usable energy. That makes it all the more important to know the difference between the two and understand what carbohydrates actually do and why you need them.

What are carbohydrates?

Humans have three macronutrients in their diets: fats, proteins, and carbohydrates. Like fats and proteins, carbs are important for a varied, well-balanced diet—especially since they are a vital source of energy for the body. In fact, an average adult should get 45-60% of their daily energy from carbohydrates.

Here’s how it works. Once carb-heavy foods are digested, they eventually turn into glucose, which the cells of our bodies absorb and use for energy to complete many daily functions. However, cells can’t process nearly all the carbs we like to eat, and the leftovers are kept in reserve for two days. If they’re still not used by that time, they are turned into fat, which the body hangs on to for a long-range energy supply in case food becomes scarce.

Because of this natural fat-morphing phenomenon, carbs have gotten a bad rap, and they are the first thing many diets will tell you to nix when you want to lose weight (though it’s been proven that low-fat diets are more effective). Regardless, not all carbs should be eliminated since completely removing them from the diet denies your body an essential nutrient it needs to function.

However, there are some types to watch out for and limit.

Types of carbohydrates

The issue is that there are different kinds of carbohydrates in many of the foods we eat—simple and complex. Generally, these are referred to as “bad” and “good” carbs. Simple (bad) carbohydrates are comprised of one or two sugar molecules, while complex (good) carbs are comprised of many chains of sugar molecules. The more dense, the more vitamins, minerals, and fiber are available for the body to use.

Simple carbs are often referred to as “empty calorie” foods and beverages, and frequently have loads of added sugar. They are a quick, albeit unsatisfying, source of energy because there aren’t any nutrients involved. Complex carbs, on the other hand, include whole grain or naturally occurring sugar sources that pack in more nutrients for your body, providing you with lasting energy.

Both simple and complex carbs are categorized into three main groups:





Foods that have a high amount of starch include:

Vegetables like peas, corn, lima beans, and potatoes

Dried legumes, such as lentils, pinto beans, kidney beans, black-eyed peas, and split peas

Grains, including oats, barley, bread, and rice

Not all starches are created equal, though. Whole grains are always a better option because they have not been processed and stripped of their health benefits. Whole grain foods include the entire kernel, which is made up of three parts—the bran, germ, and endosperm. The bran and germ contain fiber, B vitamins, minerals, essential fatty acids, and vitamin E. Conversely, refined grains (like your typical white bread), contain only the endosperm, which doesn’t have much nutritional value.


Sugars are grouped into two types:

Naturally occurring sugars, like those in milk (lactose) or fruits (fructose).

Added sugars, which are used in processed foods. Fruit that has been canned and placed in heavy syrup is a prime example.

While some assume all sugars are bad, that’s not the case. Fruit is a healthy food that naturally has sugar in it and is supposed to be eaten multiple times per day.

However, the processed products is where we again run into issues—many have added sugars that go by a variety of names including:

Anhydrous dextrose

Cane crystals or cane sugar

Corn sweetener, corn syrup, or corn syrup solids

Crystal dextrose

Evaporated cane juice

Fructose sweetener

Fruit juice concentrates

High-fructose corn syrup

Liquid fructose

Malt syrup

Natural sweeteners like raw honey, pure maple syrup, and agave nectar can be enjoyed in moderation since they don’t have the same effects and are therefore less damaging.


Fiber comes strictly from plant foods and are indigestible. Rather, fiber passes through your intestines—some of it cleansing the large intestine and some of it removing cholesterol and fatty acids from your stomach. Consuming 25-30 grams of fiber daily not only provides plentiful digestive health benefits of keeping you regular and keeping cholesterol low, but it also helps you portion food more appropriately since it keeps you feeling full and satisfied.

You can’t really go wrong with adding more of any source of fiber in your diet. Here are some foods to consider:

Legumes such as black beans, kidney beans, pinto beans, garbanzo beans, white beans, and lentils

Fruits and vegetables—ones with edible skin or seeds (apples, corn, and berries) will pack even more fiber

Whole grains including whole wheat pasta and whole grain cereals and breads

Nuts of all kinds—peanuts, walnuts, and almonds are excellent choices

Bad carbs

We’ll start with the bad news first. Bad carbs, which have little health value, are found in many popular snacks and sweets, including:

Desserts such as ice cream, cookies, cakes, and candy

Breads not made from whole grains

Pastries such as croissants or scones

Sugary beverages like soda and fruit drinks

Potato chips, crackers, fried foods, and pizza

Pastas that are not made from whole grains

You may enjoy indulging in foods that have bad carbs in them from time to time, but a diet heavy in these types of foods can negatively impact your overall health. People who regularly eat too many bad carbs can experience:

Weight gain. Eating the above foods packs on the calories, which your body can’t really use since they offer little nutritional value. When you eat large amounts of bad carbs, greater amounts of insulin are also needed, which can in turn lead to insulin resistance and cause fat accumulation.

Bowel issues. Fiber is an excellent way to keep your large intestine healthy, but you’ll only find it in plant-based foods.

Nutrient deficiency. The food pyramid acts as an excellent reminder that your body won’t get much out of highly processed foods. Instead of sweets and refined carbs, the whole grain options, vegetables, and fruits make up the majority of what your body truly needs to operate.

Risk of diabetes. Many of the bad carb options are packed with sugar. Eating too many of them could cause your blood sugar levels to easily get out of control, especially if there is a family history of diabetes.

Risk of heart disease. Refined carbs increase your triglyceride count, which is a type of fat circulating in your blood. Once this number gets too high, your risk of stroke and heart attack increases.

Good carbs

As you might have already guessed, the healthiest types of carbs are found in natural, whole foods. When eaten on a regular basis, they contribute to a healthy diet and provide vitamins, minerals, fiber, and a slew of nutrients that add to your overall well-being.

Some examples of carbohydrates that you should always add to your diet include:



Whole grain breads

Grains including quinoa, brown rice, bulgur, buckwheat, and couscous

Fruits including bananas, blueberries, plantains, oranges, and apples

Vegetables including broccoli, carrots, sweet potatoes, celery, beets, spinach, cucumbers, bell peppers, and tomatoes

Cornflakes or all bran

Consistently consuming good carbs can positively impact your health. When you increase the amount of whole grains, vegetables, fruits, and other good carb-friendly foods, you’ll experience:

Easier weight management. Consuming foods with good carbs offers your body the nutritional value and energy you need. You’ll also feel much more satisfied after a meal of whole grains and vegetables than after consuming a bowl full of potato chips.

Healthy bowel movements. Fiber is a vital player in staying regular and keeping your large intestine as healthy as possible.

Heart health. Just as consuming bad carbs will increase cholesterol, it’s much easier to manage cholesterol levels on a diet of whole grains and good carbs.

Adding more good carbs into your diet

Want some easy ways to incorporate more (good) carbs into your diet? Try these tips:

Start the day right. Carbs give you energy, after all, so why not make it your first meal of the day? Enjoy a hot cereal like this homemade oatmeal made with rolled oats, dried fruit, spices, protein powder, and coconut sugar. Or give quinoa porridge a try. You could also opt for a regular cold cereal that has a whole grain listed high up in the ingredients list and doesn’t contain a lot of sugar, such as this pumpkin flax granola. A good tip is to look for something with at least four grams of fiber and no more than eight grams of sugar per serving.

Use whole grain breads. Opt for 100% whole wheat bread or any kind that lists the first ingredient as whole wheat, rye, or another whole grain. Enjoy as your morning toast or as part of your lunch or mid-day snacks.

Think outside the (bread) box. Yes, bread is usually a go-to carb option, but remember that grains like brown rice and quinoa are also prime carbohydrates. Try these creative food swaps so you can still eat your pizza, tortillas, and more without the bad stuff.

Opt for whole fruit instead of its juice. Fruit juice is certainly a better option than soda, but even then you’re losing much of the natural goodness you would get eating it whole, including a good amount of fiber.

Beans instead of potatoes. Sure, potatoes are an easy option, but beans can be just as versatile and delicious. Potatoes can contribute to weight gain, while beans will fill you up just the same and are an amazing source of good carbs. Not only that, but you’ll also get a nice dose of protein as well.
