This is a YouTube video titled "How What And When You Eat Drives Cancer Growth" containing a talk or lecture recorded on December 5, 2020. The speaker, Valter Longo, discusses the role of insulin and insulin-like growth factor (IGF-1) in cancer growth, explaining how reducing insulin signaling through dietary choices and intermittent fasting can impact cancer risk.
So we know that insulin is a very potent growth factor. There's this thing called insulin-like growth factor or IGF-1. And Valter Longo actually described this group of Ecuadorian dwarves, the Laron dwarves, who actually have almost no IGF-1, so they're very short. Turns out they're also immune to cancer because if you don't have that growth signaling, then the cells can't grow and the cells that are gonna be the most affected are those cancer cells. So what you have to do, of course, is say that, okay, if we have too much insulin, then that's going to be a signal to our body that we need to grow. So what can you do to sort of reduce that insulin signaling in the body by reducing nutrient availability, which is two things. One is getting rid of the hyperprocessed foods, which tends to really amplify the insulin response. So sugar, for example, is especially bad because it causes all this insulin resistance, which causes hyperinsulinemia. A lot of the refined foods are very bad because they sort of take away all the other natural components and you're left with this big spike of insulin. Like if you eat cookies, for example, well, you know, it's just gonna, your insulin is just gonna spike up. And the other thing, of course, is if you eat very, very frequently, you're going to keep insulin high all the time. So intermittent fasting is another strategy that you could use to reduce insulin. And that's so it's what you eat and when you eat. Yeah, exactly.
