In this brief segment of his YouTube video, Dr. David Perlmutter explains three food items he avoids storing at home: regular sugar, agave nectar, and fruit juice. He argues that sugar is unnecessary for humans and labels it "the devil," recommending allulose as a low‑calorie sweetener alternative. He describes agave nectar as about 70% fructose, deeming it one of the worst sweeteners to consume. He also avoids fruit juice because of its high fructose content. While acknowledging a desire for sweetness, he suggests using allulose as a workaround.

Chapters

We would never have these 3 things in our kitchen. Number 1, a bag of sugar or any container of sugar. Why? Sugar is the devil. We don't need sugar. There's no human requirement for sugar. If you need to sweeten something, use allulose. Second thing is this agave, agave nectar that we hear all about at the health food stores being good for us. It's 70% fructose. It is about the worst thing that you could consume. The third thing is we don't generally have any fruit juice. Why? So high again in sugar, mostly fructose. There are workarounds if you find the desire for something sweet, as I just described, but these are the things we don't generally keep in our kitchen.
