When does sugar work for the brain, and when does it work against it? What’s needed for the optimal use of sugar in the body?

Dr. Russell Blaylock knows what it takes to keep a brain in top condition. He was a neurosurgeon for 25 years, alongside which he had a nutritional practice. Sugar, he says, isn’t always nutritionally bad for the brain.

“And we found that people’s memory improves if you give them glucose,” he says.

“For instance, you can take Alzheimer’s patients and give them a drink with [glucose] and their memory gets better temporarily,” he adds.

Of course, eating too much of the “wrong” sugar has its risks. It’s clearly connected to obesity, and with that comes higher risk of heart disease, type 2 diabetes, certain cancers, and other diseases. But whether sugar is helpful or harmful to the body depends on the form it’s in—for example, whether it’s a simple sugar or complex sugar, and whether the right nutrients are there to help metabolize it.

“It requires enzymes to slowly break the sugar down to produce these different elements that are used during [cellular processes], like the Krebs cycle and electron transport,” Dr. Blaylock explains.

Today, Dr. Blaylock joins Vital Signs with Brendon Fallon to reveal sugar in both its harmful and healthy forms, and to explain how we make it work best for our bodies.
