List Of Refined Carbs And Why They Are Bad For You September 27, 2018

Ever heard of simple things causing complex problems? Well, refined carbs do that. Refined carbs are processed carbs that affect the body by causing a quick spike in the insulin levels (1). Most snacks, fried foods, and sugary treats are loaded with simple carbs. And consuming these in excess over a period can cause obesity, diabetes, PCOS, and cardiovascular diseases (2), (3), (4). Hence, you must avoid or limit the intake of refined carbs. But which foods are refined carbs? Are all carbs bad? Read on to find the answers to your questions. We have also compiled a list of foods that are refined carbs, carbs that are good for you, and much more. Swipe up!

Refined carbs are processed carbs – which means most of the minerals, vitamins, and fiber are removed.

Complex carbs are good or healthy carbs that contain dietary fiber (complex and large molecules) that gets slowly digested and does not cause a quick spike in glucose levels. Whole grains, fruits, and veggies are complex carbs. However, processing (milling and grinding) the healthy carbs reduces the particle size of the carbs and make them get digested and absorbed quickly into the body (5). This process results in a spike in the glucose levels and can lead to many health complications.

But before we get to why refined carbs are bad for you, let’s take a look at the list of foods that are sources of refined carbs.

Sources Of Refined Carbs

  • Refined flour
  • Milk powder
  • Pasta
  • White bread
  • White rice
  • White sugar
  • Breakfast cereals
  • Pastries/cakes
  • Doughnuts
  • Churros
  • Wafers and snacks
  • Sweets
  • Mashed or fried white potatoes
  • Soda
  • Packaged fruit/vegetable juice
  • Energy drinks
  • Batter fried foods
  • Biscuits

The list may make you a little sad, but once you know what these foods can do to your body, you’d probably want to avoid or limit consuming them. Here’s how refined carbs affect your body and why it is best to avoid them.

Refined carbs are bad for various reasons. Here are some evidence-based reasons you should limit or avoid consuming refined carbs:

  • Refined Carbs Are Low In Nutrients

As you can tell from the refined carbs foods list, all of them taste good and have a feel-good effect on us. But these foods are high in calories and have zero nutritional value.

During the processing, the whole grains are stripped of the bran (outermost layer of whole grains) that contains fiber, vitamins, and minerals. The germ is also removed during processing, which contains vitamin B, antioxidants, phosphorus, magnesium, iron, selenium, and manganese.

So, with the most nutritious part removed from the whole grain, refined carbs are just empty calories that you consume (6).

  • Refined Carbs Raise Blood Glucose

Refined carbs have no nutritional value. They are high in calories and have a high glycemic index.

Glycemic index is a number given to a food, depending on how it affects the blood glucose levels (7). Refined carbs tend to raise the blood glucose levels quickly, and they have a short-term effect on satiety.

On the other hand, complex carbs are low glycemic index foods and low in calories and keep you full for a longer duration.

  • Refined Carbs Make You Diabetic

When the blood glucose levels rise, the beta cells in the pancreas secrete insulin (8). Insulin helps shuttle the glucose molecules into the cells, where glucose is converted to usable energy.

But when you consume too many refined carbs and keep consuming them in the form of snacks and sugary treats, the blood glucose and insulin levels remain high. Over time, your body becomes insulin resistant, i.e., the cells stop recognizing insulin (9). As a result, the blood glucose levels remain high. The cells are devoid of glucose, making you lethargic and hungry all day long.

So, you consume food, but to no effect as your blood glucose levels soar high. The end result – obesity, diabetes, and PCOS (10), (11).

  • Refined Carbs Cause Obesity

Refined carbs get digested and absorbed into the body easily and quickly. As a result, you tend to feel hungry quickly, which can make you prone to binge eating (12). Though you “feel” you are hungry, your body actually has more glucose in store than the energy it needs to perform normal body functions. So, the extra glucose is stored in the body as fat.

Scientists have also found that consuming too many refined and simple carbs causes inflammation in the body. Simple and refined carbs tend to stimulate triglycerides-forming enzymes, and the fat cells release free fatty acids that activate the inflammatory signaling pathways (13). When your body is constantly under stress with high levels of inflammation, it stores calories you consume in foods as fat.

  • Refined Carbs Cause Belly Fat

The more you consume refined carbs, the more the chances that you will accumulate fat in your belly region. It is one of the most dangerous types of fat and is tough to get rid of.

Many studies have established that long-term consumption of excessive refined carbs can increase stress levels, causing fat molecules to get accumulated in the visceral cavity (14), (15).

  • Refined Carbs Increase The Risk Of Heart Disease

Refined carbs get digested and absorbed easily, making you overeat. Your body starts to store the excess glucose as fat, and the triglyceride levels also shoot up. If you do not keep a check on your refined carb intake, you will be at the risk of fatal heart disease.

Scientists found that people who consumed whole grains were at lower risk of heart disease than people who consumed refined carbs (16).

  • Refined Carbs Cause Gut Problems

The good gut bacteria help in digestion, and they feed on dietary fiber found in food sources of complex carbs. But refined carbs have no dietary fiber.

Being on a high-refined carb diet can reduce the number and variety of good gut bacteria, which can affect digestion and cause constipation (17).

  • Refined Carbs Intake May Cause Cancer

Being on a high-refined carb diet may increase the risk of cancer (18), (19). Refined carbs are closely related to obesity caused by inflammation in the body.

When your body is in a constant state of inflammation, your body’s stress levels go up. And this may trigger DNA mutation, leading to the production of proteins that may cause cancer.

It is clear that refined carbs are potentially dangerous for you and are one of the main reasons for the obesity epidemic and many other related health issues. The best way to tackle this problem is to replace the refined carbs with good carbs and nutrient-dense foods. Here’s how you can do that.

It’s not tough to get rid of the bad carbs from your diet. Here’s another list of foods containing good carbs that you can consume.

Sources Of Good Carbs

  • Fruits
  • Veggies
  • Nuts
  • Freshly pressed fruit/vegetable juice (without sugar)
  • Whole grains
  • Homemade salads

  • Popcorn

Conclusion

Learning to fine-tune your carb cravings plays a big part in the way you treat your body. Killing your soul and depriving your body will not work. Neither will overeating and consuming high amounts of refined carbs. Start limiting the quantity of refined carbs you consume per day. And over a period, you will be able to avoid refined carbs completely and not even crave for them. Start today and provide your body the food that it really needs and deserves. Take care!
