A Confusing Issue
I often hear people say that carbs are bad. I’ve heard conversations where people say they are cutting out carbs to lose weight.
It seems as though there are countless conflicting opinions on carbs.
So, are carbs (carbohydrates) good or are they bad?
The real, true, and accurate answer is that it depends.
As you may have surmised, all carbs are NOT created equally.
Black beans and candy bars are both loaded with carbs. However, I’m sure you’ll agree that they have vastly different effects on health.
Some Physiology Made Easy
Let’s take a step back for a moment and talk about the foundational knowledge you must have for a better understanding regarding the healthfulness of carbs. Your body needs carbs, as does mine. In fact, everyone needs carbs. The human body was designed to utilize carbohydrates as its primary fuel source. This is why our bodies make the hormone insulin, which is the key that allows glucose (a carbohydrate) to enter our cells. Our bodies make insulin so that our cells can utilize the glucose in our bloodstream (obtained from eating carbs) as their preferred energy source.
Let me repeat that. Our bodies make insulin so that our cells can utilize the glucose obtained from eating carbs as their primary and preferred energy source. Think about that for a minute. Why would the human body waste time and energy to make insulin if it did not use glucose as its main energy source? Looking at this from another perspective, people with diabetes, whose bodies are either unable to produce insulin or are resistant to their insulin, have such profound abnormalities of their physiology that they often end up developing many devastating complications.
Although this was a very general overview, I hope it is clear that insulin is a critical component of our health and that glucose (a carbohydrate) is the principal energy source of our cells. OUR BODIES NEED CARBS TO FUNCTION NORMALLY.
Back to the Question
Knowing this, all carbs must be good, right? Not exactly. As I said, not all carbs are created equally. Some carbs, such as those from black beans, are naturally combined with vitamins, minerals, and, most importantly, fiber, which prevents those carbs from being absorbed too quickly. Other carbs, such as those in candy bars and other ultra-processed foods, are just sugars added into the mix of a food product that is devoid of nutrients and fiber. The carbs in these foods are absorbed by our bodies quickly. It is this rapid absorption that leads to a host of metabolic derangements that can eventually lead to diseases such as type 2 diabetes. This is in stark contrast to the slow absorption of carbs in foods such as black beans, which provides the body with the glucose it needs while avoiding all these problems.
To summarize, ultra-processed foods are exceedingly unhealthy, and you now know one reason why. Foods such as black beans, which are whole, plant-based foods, are exceedingly healthy, and you now know one reason why. All whole, plant-based foods are also tremendously healthy for the same reasons.
What are whole, plant-based foods? Fruits, vegetables, whole grains, legumes, nuts, and seeds.
Practical Application
Following the reasoning outlined in this piece:
Our bodies expend the energy to make insulin so that carbohydrates can be utilized as the primary fuel source for our cells. Since healthy carbohydrates are found in abundance in whole plant foods, these are the types of foods that our bodies were designed to eat the most of.
Need more convincing?
There was a study called the BROAD study (click here for link to article). This study looked at the effects on body weight of allowing people to eat AS MUCH as they wanted of a whole food, plant-based diet. Yes, you read that correctly. The study participants were allowed to eat as much as they wanted—calories were not restricted. And even when eating as many whole, plant foods as they wanted, they still had significant weight loss. This is remarkably empowering knowledge.
So, please enjoy your good carbs, the ones from whole plant foods, and rest easy knowing that they are truly good for your health and your weight.
