Insulin is a hormone that is produced by the pancreas and plays a critical role in regulating blood sugar levels in the body. It is an underappreciated biomarker that is often overlooked by healthcare providers, despite its importance in maintaining overall health.
Insulin works by helping glucose (sugar) in the bloodstream to enter the cells where it can be used for energy. When the body produces too much glucose, the pancreas produces insulin to help remove the excess sugar from the bloodstream. If the body produces too little insulin or the insulin produced is not effective, the result is high blood sugar levels, which can lead to a variety of health problems, including diabetes, heart disease, and stroke.
Insulin is important for several reasons, including:
Regulating Blood Sugar Levels
Insulin is critical for regulating blood sugar levels in the body. When insulin levels are low, glucose remains in the bloodstream, leading to high blood sugar levels. This can cause damage to blood vessels and organs over time, leading to a range of health problems, including diabetes.
Promoting Fat Storage
Insulin plays a role in promoting the storage of fat in the body. When insulin levels are high, the body stores excess glucose as fat, which can lead to weight gain and obesity. This can increase the risk of a range of health problems, including heart disease, stroke, and type 2 diabetes.
Supporting Brain Function
Insulin also plays a role in supporting brain function. It helps to regulate glucose levels in the brain, which is critical for brain function and cognitive performance.
Despite its importance, insulin is an underappreciated biomarker that is often overlooked by healthcare providers. This is partly due to the fact that insulin is often measured indirectly, through the measurement of blood sugar levels. However, measuring insulin levels directly can provide important information about overall health and can help to identify potential health problems before they become more serious.
Measuring insulin levels can be done through a simple blood test. An insulin level of less than 5 micrograms per milliliter (mcg/mL) is considered normal, while levels higher than 20 mcg/mL may indicate insulin resistance, which can lead to type 2 diabetes.
In addition to measuring insulin levels directly, there are several ways to support insulin function and promote overall health:
Exercise is one of the most effective ways to support insulin function and regulate blood sugar levels. Regular exercise can help to increase insulin sensitivity, which means the body needs less insulin to regulate blood sugar levels. This can help to reduce the risk of developing diabetes and other health problems.
Eat a Healthy Diet
Eating a healthy diet that is rich in whole foods, fruits, and vegetables can also help to support insulin function and regulate blood sugar levels. Avoiding processed foods and sugary drinks can help to reduce the risk of developing insulin resistance and other health problems.
Stress can have a negative impact on insulin function and blood sugar levels. Managing stress through mindfulness meditation, yoga, or other relaxation techniques can help to support overall health and promote insulin function.
In conclusion, insulin is an underappreciated biomarker that plays a critical role in regulating blood sugar levels and supporting overall health. Measuring insulin levels directly can provide important information about overall health and can help to identify potential health problems before they become more serious. Supporting insulin function through regular exercise, a healthy diet, and stress management can help to promote overall health and reduce the risk of developing diabetes and other health problems.
