Insulin growth factor 1, or IGF-1, is a hormone that plays an essential role in growth and development during childhood and adolescence. However, recent research has shown that IGF-1 may also play a role in the aging process.
Studies have found that lower levels of IGF-1 are associated with increased longevity in animals and humans. In one study, researchers found that mice with lower levels of IGF-1 lived up to 50% longer than their counterparts with higher levels of IGF-1. Similarly, in a study of humans, centenarians were found to have significantly lower levels of IGF-1 than their younger counterparts.
So how does IGF-1 contribute to aging? One theory is that high levels of IGF-1 can lead to an overgrowth of cells, which can increase the risk of cancer. Additionally, high levels of IGF-1 have been linked to an increased risk of age-related diseases such as diabetes and cardiovascular disease.
So how can we lower our levels of IGF-1? One way is through dietary changes. Studies have found that a low-protein diet can lead to lower levels of IGF-1. This may be because protein stimulates the production of IGF-1 in the body.
Another way to lower IGF-1 levels is through intermittent fasting. Studies have found that fasting can lead to a decrease in IGF-1 levels, which may contribute to the anti-aging benefits of fasting.
While more research is needed to fully understand the role of IGF-1 in aging, it’s clear that this hormone plays a crucial role in the aging process. By making simple dietary changes and practicing intermittent fasting, we may be able to lower our levels of IGF-1 and potentially slow down the aging process.
If you’re interested in trying a low-protein diet or intermittent fasting, there are a variety of resources available to help you get started. Additionally, there are supplements available that may help support healthy aging and lower IGF-1 levels. However, it’s important to consult with a healthcare professional before making any significant dietary changes or taking supplements.
