The Science Behind Normal Blood Sugar Range Explained Blood sugar is a vital component of our body's energy production system. When we eat carbohydrates, they break down into glucose (sugar), which is then absorbed by the bloodstream. Under normal circumstances, cells in the body use this glucose for fuel through insulin action. However, when blood sugar levels drop below 70 mg/dL, it can lead to a condition known as hypoglycemia or low blood sugar.
The ideal range for healthy living varies slightly depending on factors such as age and health conditions. Generally speaking, adults aim for pre-meal readings of less than 100 mg/dL and postprandial (after meal) levels below 140 mg/dL. Maintaining this balance is crucial because fluctuations in blood sugar can lead to a host of complications including heart disease, vision impairment, kidney damage, and nerve damage.
What Causes Fluctuations in Your Blood Sugar Range? One primary cause of fluctuating blood sugar is the food we consume. Carbohydrates are broken down into glucose quickly; however, fiber-rich foods like fruits and vegetables take longer to digest. High-fiber diets tend to promote better insulin sensitivity – a condition where cells respond well to insulin allowing for more efficient energy uptake.
Another vital factor influencing blood sugar levels is physical activity or exercise. Exercise can cause the body's muscles to absorb glucose from the bloodstream, which may drive down blood sugars temporarily but also improves insulin sensitivity in many people over time when exercised regularly and moderately intensively during this early phase so as not only improve glucose metabolism further by increasing uptake efficiency thereby helping lower overall risk factors associated with diseases related especially those affecting major organs such liver heart etc...
