It’s often assumed that we can’t change our genes — so why even try? The truth is that while we can’t change our DNA code, our gene expression is a bit of a different story. Our genes express themselves in different ways, and not only affect how we interact with the world around us, the world around us affects how our genes express themselves. That means that lifestyle and food choices we make can actually influence how our genes work. Our genes aren’t set in stone, and there’s a lot we can do to help them impact our health.
