Glucose fuels every cell in your body, and it all starts with plants. Biochemist Jessie Inchauspé unpacks the biology of carbs and how to eat them smart.
Key Takeaways
- Plants don’t grow from soil—they build themselves from air and sunlight through photosynthesis.
- Glucose is the foundational molecule of life, created by plants and used by every living creature.
- Carbohydrates include starch, fiber, glucose, and fructose—each with different effects on the body.
- Humans crave carbs because we evolved to seek glucose-rich foods for survival.
- Today’s processed foods hijack that craving with dangerous glucose surges and addictive design.
- Fiber is technically a carb, but it doesn’t raise glucose and plays a protective role.
- Glucose spikes contribute to major health issues, including type 2 diabetes, fatigue, and inflammation.
- Smart eating strategies—like savory breakfasts and pairing carbs with fat/protein—can balance blood sugar.
- Physical activity post-meal helps the body utilize glucose efficiently, reducing harmful spikes.
Photosynthesis: The Invisible Power Behind Every Carbohydrate
- Jessie compares photosynthesis to humans sunbathing and spontaneously creating soup in their stomachs—an elegant metaphor for how effortless energy creation is for plants.
- The breakthrough began with Van Helmont's 5-year "willow experiment", where he proved plants don’t grow from soil. Despite a willow tree gaining 164 lbs, the soil weight stayed the same.
- This proved that plants build themselves from carbon in the air and water—not dirt.
- Using sunlight as energy, plants convert carbon dioxide and water into glucose—a tiny but powerful molecule.
- This glucose forms the structural and energy backbone of the plant, created through what we now call the Calvin-Benson-Bassham cycle, a Nobel Prize-winning discovery.
Plants aren’t just passive greenery. They're biochemical factories, constantly manufacturing the molecules that fuel the entire food web—including us.
What Happens to Glucose Inside Plants
- Once glucose is made, plants use it in three major ways:
- Starch: Glucose molecules are chained together and stored for energy, especially in roots and seeds (like carrots, potatoes).
- Fiber: This is how plants stand upright. Without fiber, they’d literally collapse. Fiber gives structure and resilience.
- Fructose: A sweet form of glucose stored in fruit to lure animals, who eat the fruit and scatter the seeds—nature’s marketing strategy.
- Glucose is incredibly small—half a million molecules could fit into the period at the end of this sentence. Yet its impact is massive.
How Humans Tap Into This Glucose Power
- We can’t photosynthesize, but we do rely on the glucose plants produce. That’s the entire point of eating carbs.
- Carbohydrates—starch, sugar, fiber—all break down (except fiber) into glucose during digestion, becoming fuel for every cell.
- Even if we don’t eat carbs, our body will synthesize glucose from protein through a process called gluconeogenesis, underlining how essential it is.
- Scientifically, fiber is still a carbohydrate, even though it doesn’t get converted into glucose or raise blood sugar.
Carbs are not a modern invention—they’re a biological necessity, but how we consume them has changed radically.
Our Deep Biological Craving for Glucose
- Humans are hardwired to seek out glucose-rich foods. This craving helped our ancestors survive in environments where food was scarce and energy was precious.
- But today, we’re surrounded by ultra-processed foods that deliver glucose in exaggerated, damaging amounts.
- Jessie warns: “A candy bar is not the same as an ancestral apple.”
- Overconsumption of glucose can lead to:
- Type 2 diabetes
- Chronic fatigue
- Mood swings and cravings
- Inflammation
- Premature aging
- Mental health issues
- The problem isn’t glucose itself—it’s that the delivery system has been corrupted by modern food manufacturing.
The Addictive Design of Modern Carbs
- Food companies intentionally engineer snacks and processed foods to be hyper-palatable and addictive.
- These products flood your bloodstream with glucose faster than your body can handle, triggering energy crashes and hunger rebounds.
- Jessie’s insight: “It’s not your fault you crave sugar. Your body is doing exactly what evolution trained it to do.”
- But we can outsmart the system—not by resisting carbs, but by eating them in a smarter, more natural way.
10 Glucose Hacks That Make Carbs Work for You
- Jessie has distilled years of biochemistry and clinical research into 10 practical “glucose hacks” to reduce blood sugar spikes.
Some key highlights include:
- Eat a savory breakfast. Starting your day with protein and fat keeps glucose levels stable and prevents a rollercoaster day.
- “Clothe your carbs.” Always pair starches or sugars with fiber, protein, or fat to slow absorption.
- In nature, carbs almost always come with fiber—this principle mimics that.
- Example: Add avocado or eggs to toast, or nuts to fruit.
- Move after meals. A light walk or any physical activity helps your muscles soak up glucose, reducing blood sugar spikes.
- Avoid eating naked carbs. That means: no lone white bread, plain pasta, or juice-only snacks.
- She also offers a plant-based supplement—“Anti-Spike Formula”—shown to reduce glucose spikes by up to 40%, backed by over 25 clinical trials.
It’s not about giving up carbs. It’s about reclaiming them as part of a healthy biological rhythm. Jessie’s hacks are designed to work with your body, not against it.
Why This Matters More Than Ever
- The modern food landscape is dramatically different from the environments our bodies evolved to thrive in.
- Jessie’s goal is to equip you with tools, not rules—to enjoy bread, pasta, and dessert without the metabolic backlash.
- Her approach is both scientific and deeply compassionate: understand your biology, then feed it wisely.
The biology of carbs isn’t just chemistry—it’s a story of plants, energy, and survival. When you learn the language of glucose, you gain back control over your health.
