Insulin is often associated with regulating blood sugar levels, but can it actually increase them? The answer lies in understanding how insulin works and its relationship with glucose.
Insulin is produced by the pancreas to facilitate glucose entry into cells. When we eat, our body releases insulin to help absorb excess glucose from the bloodstream. However, when we produce too much or have a resistance to insulin, it can disrupt this balance. Insulin sensitivity plays a crucial role in how effectively our bodies use insulin.
Insulin Resistance: A Common Culprit Behind Rising Blood Sugar Levels
Research suggests that up to 50% of adults worldwide suffer from some level of insulin resistance (1). This means their bodies have become less responsive to the hormone, causing them to rely on alternative energy sources. When left unchecked, this can lead to an overproduction of insulin and subsequent increase in blood sugar levels.
For instance, a study published in The Journal of Clinical Endocrinology & Metabolism found that participants with pre-diabetes or type 2 diabetes had significantly lower insulin sensitivity compared to those without these conditions (2). Conversely, studies have consistently shown improved insulin sensitivity through lifestyle changes such as exercise and diet modification.
How Diet Plays a Role in Balancing Insulin Levels
Certain foods can help boost our bodies' natural ability to produce and use insulin. Including high-fiber foods like whole grains, fruits, vegetables, lean proteins in meals not only helps stabilize blood sugar but also provides key nutrients for optimal metabolic health (3).
Some specific examples of these beneficial food choices include:
- Oatmeal
- Greek yogurt
- Berries As seen above while maintaining a healthy diet can certainly have its benefits; however over-reliance on high-carb foods, sugars or alcohol and stress significantly disrupt insulin production causing an increase in the blood sugar levels.
The Role of Stress in Disrupting Blood Sugar Balance
Stress affects our bodies' natural ability to regulate glucose by altering cortisol hormone production. High cortisol levels suppresses insulin release which causes our body's cells are less receptive to available glucose (4). While it can be impossible to avoid stress completely; practices like yoga, meditation and mindfulness have demonstrated reduced effects on blood sugar spikes when dealing with stressful situations.
In summary: Insulin plays a pivotal role in maintaining balanced blood sugar levels. As seen above understanding the interplay between insulin sensitivity food intake lifestyle choices & daily stresses allow individuals better handle their body's natural process to ensure optimal health
