Q&A with Leyla, Part 1: Gingivitis

How reliable is nutrition science?

I have gingivitis, and my dentist recommended Listerine. Won't that disrupt the microbiome in my mouth?

I take a diuretic for high blood pressure. Is it okay to stop drinking water by 8pm, or will I dehydrate?

Is there a way to get rid of seborrheic keratoses?
