From Saving Grace to Poisonous Demise

Millions of years ago, finding a fruit tree was the equivalent of finding a 100-dollar bill on the ground. These rare, sweet finds would be a sign of comfort in an otherwise challenging world. Fruits were a quick and robust energy source that could fuel you for the next few days. Fast forward to today, and that primal urge has become our downfall. Our hunter-gatherer bodies, designed for occasional sugar windfalls, now have access to an ocean of processed carbs and refined sugars.

The current abundance of glucose-rich foods has turned our ancient survival trait into a health hazard. Diabetes, once virtually unknown, now affects millions globally. The very glucose that fueled our ancestor's survival now threatens our well-being.

How did we go from mere fruit foragers to a species facing a diabetes epidemic? After exploring our bodies' most essential fuel through the carbohydrate glucose system - let's now learn how we can deal with living in a sugar-saturated world that our ancestors could never have imagined.

Key Points

‍

The Dysregulation of Nutrition from the Modern Diet

The modern diet, often characterized by processed foods, excessive sugar, and refined carbohydrates, has significantly disrupted the delicate balance of macronutrients our bodies evolved to process. This imbalance contributes to unregulated glucose levels and metabolic dysfunction in several ways:

‍

Carbohydrate Overload:

Modern diets are frequently carbohydrate-heavy, particularly in refined and processed forms. These rapidly digestible carbs flood the bloodstream with glucose, leading to sharp spikes in blood sugar. Our bodies which adapted to handle occasional sugar influxes from whole foods struggle to cope with this constant onslaught. The result is frequent insulin surges, which over time can lead to insulin resistance and impaired glucose regulation.

Protein Inadequacy:

While not typically deficient in absolute terms, protein intake is often proportionally lower in modern diets. Adequate protein is crucial for maintaining muscle mass, which plays a key role in glucose uptake and metabolism. Furthermore, protein helps moderate the absorption of carbohydrates, blunting glucose spikes. Its relative absence in many meals contributes to poor glycemic control.

Imbalanced Fat Consumption:

Modern diets often feature an overabundance of unhealthy fats (trans fats, excessive saturated fats) and an inadequate intake of beneficial fats (omega-3s, monounsaturated fats). This imbalance can promote inflammation and interfere with insulin sensitivity. Healthy fats are crucial for hormone production, including those involved in glucose regulation, and their disruption can impair metabolic function.

Fiber Deficiency:

The processing of many modern foods strips away fiber, a crucial component for slowing glucose absorption and promoting gut health. This lack of fiber contributes to rapid glucose spikes and poor overall glycemic control.

Micronutrient Gaps:

Highly processed diets often lack essential micronutrients necessary for proper metabolic function. Deficiencies in vitamins and minerals like magnesium, chromium, and vitamin D can impair insulin sensitivity and glucose metabolism.

Caloric Excess:

Modern diets often provide an excess of calories, particularly from added sugars and refined carbs. This overabundance strains the body's ability to process and store glucose effectively, leading to chronic elevated blood sugar levels.

Disrupted Eating Patterns:

The modern lifestyle often involves irregular eating patterns, large portion sizes, and frequent snacking, particularly on carb-rich foods. This constant food intake, especially of glucose-spiking foods, doesn't allow the body's insulin levels to normalize, further contributing to glucose dysregulation.

‍

The Result: Insulin Resistance and Type II Diabetes

Our nutritional landscape, so different from the whole food, balanced diets our bodies are adapted to, creates a perfect storm for glucose mismanagement. The constant high-carb, low-fiber intake overwhelms our insulin response, while inadequate protein and imbalanced fats fail to provide the metabolic support needed for proper glucose regulation. Over time, this can lead to insulin resistance, prediabetes, and eventually, type 2 diabetes. Alarmingly, nearly 6 million Canadian adults have prediabetes, a condition where blood sugar levels are higher than normal but not yet high enough to be diagnosed as diabetes. This statistic underscores the importance of understanding and maintaining healthy glucose levels. Addressing this imbalance by returning to more whole foods, balanced macronutrient intake, and mindful eating patterns is crucial for restoring proper glucose regulation and overall metabolic health.

‍

A Healthy Diet

The most obvious way to regulate your glucose levels is through diet. A well-balanced diet is crucial for maintaining stable blood sugar levels. Here are some specific dietary strategies:

1. Choose low glycemic index (GI) foods: Opt for whole grains, legumes, and non-starchy vegetables, which release glucose slowly into the bloodstream.

2. Increase fiber intake: Aim for 25-30 grams of fiber daily from sources like vegetables, fruits, and whole grains to slow glucose absorption.

3. Balance macronutrients: Include lean proteins and healthy fats with carbohydrates to slow digestion and prevent rapid blood sugar spikes.

4. Practice portion control: Use smaller plates and follow the plate method (1/2 non-starchy vegetables, 1/4 lean protein, 1/4 complex carbohydrates) to manage calorie intake.

5. Stay hydrated: Drink plenty of water throughout the day to support proper insulin function and glucose regulation.

‍

Burning Through the Fuel - Remaining Active

The other main cause of unregulated glucose consumption is our bodies often aren’t active enough to burn through all of the stored energy we consume through our diet. Possibly as equally important as our diet is how quickly and often we use our bodies to burn through the fuel we consume. If you think of the glucose intake as the gas tank being overfilled, one option is to stop filling the tank so much, which would be controlling our diet. The other option would be to increase pressure on the gas pedal to burn through the fuel more quickly. This is how exercise and staying active helps regulate our internal glucose system. 

‍

1. Aerobic exercise: Engage in moderate-intensity activities like brisk walking, cycling, or swimming for at least 150 minutes per week to enhance insulin sensitivity.

2. Resistance training: Incorporate strength exercises 2-3 times weekly to build muscle mass, which increases glucose uptake and storage.

3. High-Intensity Interval Training (HIIT): Short bursts of intense exercise followed by recovery periods can significantly improve glucose regulation and cardiovascular health.

4. Post-meal walks: A 10-15 minute walk after meals can help lower post-prandial glucose levels.

5. Consistency is key: Aim for regular, daily movement rather than sporadic intense workouts for optimal glucose control.

‍

Healthy Glucose Levels

Maintaining optimal glucose levels is essential for overall health and preventing diabetes. Several key biomarkers are used to assess glucose regulation:

1. Hemoglobin A1c (HbA1c): This test measures average blood sugar levels over the past 2-3 months. A healthy HbA1c level is below 5.7%, while 5.7% to 6.4% indicates prediabetes.

2. Fasting Plasma Glucose (FPG): Measured after an 8-hour fast, normal FPG levels are below 5.6 mmol/L (100 mg/dL). Values between 5.6-6.9 mmol/L (100-125 mg/dL) suggest prediabetes.

3. Fasting Insulin: This test helps assess insulin sensitivity. While reference ranges can vary, levels above 30-60 pmol/L (5-10 μIU/mL) may indicate insulin resistance.

‍

Continuous Glucose Monitoring (CGM)

Continuous Glucose Monitoring (CGM) is a revolutionary tool for understanding individual glucose patterns. Unlike traditional finger-prick tests, CGM provides real-time, continuous data on blood glucose levels throughout the day and night.

Benefits of CGM include:

• Identifying glucose trends and patterns
• Understanding how diet, exercise, and stress affect blood sugar
• Detecting nighttime hypoglycemia or hyperglycemia
• Improving overall glucose management

CGM can be particularly beneficial for those with prediabetes or at risk of developing type 2 diabetes, as it allows for early intervention and personalized lifestyle modifications.
