My young patient recently shared that every time he eats red pasta (a mixture of noodles, vegetables and tomato sauce), his blood sugar suddenly drops. Typically, during fasting, normal blood glucose readings of 70-100 mg/dl are below 140 mg/dL within two hours of eating. He said he went for a walk after meals and felt dizzy when he ate bananas and candies to raise his level.
Many people have noticed that certain foods affect energy levels in amazing ways, if they hadn't had a formal diagnosis. One of the most confusing situations is when a high-carb diet like pasta leads to a sudden collision of blood sugar rather than a blood sugar spike. So, what's going on?
At first glance, pasta is like a high-carb diet in a textbook. Most people expect to significantly increase their blood sugar levels. And in many cases, that's true. However, the body's responses vary depending on multiple factors, including the type of pasta, portion size, sauce ingredients, timing of physical activity, and individual insulin sensitivity. This is more common than people think, especially in people with insulin resistance, early stage diabetes, or other metabolic imbalances.
Refined carbs and quick crash
White pasta is a refined carbohydrate. During processing, the fibrous bran and nutrient-rich germ of wheat nuclei are removed, leaving behind starchy endosperm. This will allow the refined pasta to be less fiber and digest quickly. When you eat it, the body rapidly breaks it down and divides it into glucose, which is quickly absorbed into the bloodstream. Even tomato sauce plays a role. Many jarred sauces have added sugar, which can be added to the first spike and subsequent crashes.
Its sharp spikes of glucose cause the pancreas to release a surge in insulin. Its job is to close that sugar from the bloodstream to cells for energy or storage. In some cases, your body may release more insulin than it needs to be, especially if you are insulin sensitive or don't eat too much fat or protein to balance your diet. result? Blood sugar crash.
Why does physical activity worsen?
Walking after a meal is a great way to stabilize blood sugar levels, but if you're already heading towards glucose dip, you can accelerate your exercise. Muscle activity draws glucose from the bloodstream and usually helps reduce high sugar levels. In this case, it can push you from “low” to “too low.” This is when symptoms such as numbness, cold sweat, and dizziness begin.
What can you do?
First, we move to complex carbohydrates such as whole wheat, lentils and chickpea pasta. By adding protein and healthy fats, it slows down glucose breakdown and subsequent release into the bloodstream. Grilled chicken, tofu, or olive oil-based sauces can slow digestion. Please see the portion sizes. A large bowl of pasta can overwhelm your system. If you have a tendency to crash, wait 30-60 minutes before going for a post-meal walk. Keep your food and blood sugar diary and find patterns.
