Richard Johnson, MD examines how fructose from sugary drinks may trigger cognitive decline and Alzheimer's changes. Drinking more than two soft drinks daily correlates with smaller brain volume. The hippocampus, essential for recent memory, is often the first brain region affected in Alzheimer's.

Is there evidence that fructose is involved in Alzheimer's? Well, remember, the main source of fructose is sugar and sugar or sucrose. And if you look at sugary beverage intake, you can see that there's a direct relationship between the more sugar you eat and the worse your memory is, both short term and long term memory. It also correlates with brain volume. This horrible study in which they did a CT scans and measured brain volume. If you're drinking more than two soft drinks a day, it's very likely that your brain volume is going to be smaller than your friends. That's not. When you think about it, that's just. That's a horrible finding. And the main area of the brain that is involved in memory, recent memory, is called the hippocampus. And that's one of the first sites hit in Alzheimer's.
