Friend or Foe – Are Carbs Healthy or Harmful?


So, are carbs healthy? The ever-evolving debate over the role carbohydrates play in our lives has been a perpetual source of confusion and contention in the world of nutrition. Carbohydrates, are one of the three macronutrients essential for human survival, alongside fats and proteins. Complex carbohydrates, simple carbs and fibre, the latest opinions on carbs seems to have seen a shift away from the traditional low-carb craze.  Carbohydrates have not changed over the years, but now we understand more about the vital role, all carbs play in a balanced diet.

Understanding the 3 types of Carbohydrates

Carbohydrates serve as the body’s primary source of energy, playing a crucial role in various bodily functions, including brain function, muscle performance, and overall metabolism.

  1. Simple Carbohydrates:

These are sugars, both natural (found in fruits and dairy products) and added (found in processed foods like candy and sugary drinks). They are quickly digested and can cause rapid spikes and crashes in blood sugar levels. When you get your natural simple carbs found in fruit and dairy products, you also get fibre, natural digestive enzymes, and nutrients that come naturally in those foods.  As opposed to eating added simple carbs from processed foods, which also bring empty calories and little nutritional value to your diet.  These added simple carbs found in processed foods, would be referred to as ‘bad’ carbs.

2. Complex Carbohydrates:

Complex carbs are found in foods like whole grains, legumes, and starchy vegetables. They contain longer chains of sugar molecules and take longer to digest, providing a more sustained source of energy. These are called ‘good’ carbs.

3. Fiber:

Fiber is a type of complex carbohydrate that the body cannot digest. It aids in digestion, promotes a feeling of fullness, and supports heart health.

The Low-Carb Craze

For years, low-carb diets like Atkins and ketogenic diets gained popularity, with proponents claiming that reducing carbohydrate intake could lead to weight loss and improved health. These diets severely restricted or even eliminated sources of carbohydrates, such as grains, fruits, and starchy vegetables.  If there were no carbs, then the body would have to burn fat for energy.

The low-carb movement garnered attention and saw initial success in some individuals, primarily due to the loss of water weight and reduced calorie intake. However, long-term adherence to such diets raised concerns about potential nutritional deficiencies, constipation, and adverse effects on heart health.

Balance your carbs by considering the following factors:

In recent years, the pendulum has swung back towards a more balanced perspective on carbohydrates. Sifting through the enormous amount of information available, is not only time consuming but can be overwhelming for many to reach an actual conclusion. To break it down in a more accessible way, we have found there are several factors that have contributed to this shift in thinking:

  1. Quality Matters: distinguish between “good” (complex carbs like whole grains, fruits, veggies, legumes) and “bad” carbs (refined, simple carbs like white bread, sugary snacks).
  2. Individual Variation: recognize that carb responses vary based on genetics, activity, and metabolic health.
  3. Embrace Moderation: opt for balanced portions of carbs alongside protein and healthy fats for stable blood sugar and satiety.
  4. Prioritize Fiber: include fibre-rich carbs for digestive health, disease prevention, and weight management.
  5. Sustainable Choices: opt for balanced, varied eating habits over restrictive diets for long-term success.

Are Carbs Healthy – The Role of Carbohydrates in Health

  1. Weight Management: Carbohydrates, especially those high in fibre, can contribute to a feeling of fullness, which may help control calorie intake and promote weight loss or maintenance.
  2. Blood Sugar Control: The type and timing of carbohydrate consumption can impact blood sugar levels. Slow-digesting complex carbohydrates can help stabilize blood sugar, whereas sugary foods and beverages can lead to rapid spikes and crashes.
  3. Heart Health: Whole grains and fiber-rich foods have been linked to a reduced risk of heart disease. They can lower cholesterol levels and help manage blood pressure.
  4. Brain Function: The brain relies on glucose, a product of carbohydrate metabolism, for energy. Consuming adequate carbohydrates can support cognitive function.
  5. Exercise Performance: Carbohydrates are a primary source of energy for athletes and active individuals. Maintaining glycogen stores through carbohydrate consumption can enhance endurance and performance.

Carbohydrates are not a fad, rather than demonizing all carbs, experts encourage people to focus on the quality of carbohydrates they consume, individualize their diets, and prioritize foods rich in fibre and nutrients. Carbohydrates have always been and remain a vital part of a healthy diet, and their role must be understood within the broader context of overall nutrition and lifestyle. I have learned that in all areas of my life and as with any aspect of nutrition, portion control and balance remain key principles for achieving and maintaining good health.
