Everything you metabolize both keeps you alive, and harms you. Like fruit? Well, pectin isn’t very good you in the long run. Metabolic activity is messy, produces toxins we need to Eli inste through urine and feces, and that’s that. We’re all dying, and no fantasy of a special diet can change that. While some diets are better for you than others, it’s not as laughably clear cut as “eating death” or whatever nonsense.
The very act of living produces toxins, period.
