Whether you'll be able to’t think about beginning your day and not using a freshly brewed cup of coffee or an ice-cold glass of juice, Dr Daniel Amen, psychiatrist and mind dysfunction specialist and director of the Amen Clinics, has dangerous news for you.

The knowledgeable defined that these two widespread drinks might be “destroying your brain”. 

Explaining what drinks can do extra harm to your brain than you assume, he revealed that a number of the “worst” choices embrace espresso and fruit juice.

Recalling a lesson he attended at his daughter's college, he stated he listed 20 drinks on a board and requested the category to separate them when it comes to which of them are “brain-friendly” and which of them aren't.

Speaking to Steven Bartlett on a latest episode of The Diary Of A CEO, the psychiatrist stated: “They got 19 out of 20 right, so most people know, but the only thing they got wrong was juice. 

“They put it in the healthy category, when in fact when is it rational to unwrap fruit sugar from its fibre source, because it turns toxic in your body, so I'm not a fan of fruit juice."

When asked by Steven about what it is that makes juice bad for the brain, Dr Amen explained the popular drink is proinflammatory and can lay the harmful groundwork for diabetes. 

The health expert added: "It's ultimately going to give you high blood sugar levels, which erode your blood vessels and you're going to have lower blood flow to your brain.

"That's a bad thing. And I mean there's so many things about it, it's addictive, it's pro-inflammatory, it makes it more likely you're going to have diabetes and obesity.

“Sugar is the gateway drug to diabetes and obesity, and not to mention inflammation, which is the cause of depression and dementia."

On the other hand, low blood sugar levels could also harm the brain. Therefore, Dr Amen also recommended avoiding caffeine.

The doctor said: "Caffeine constricts blood flow to the brain by 30 percent." Revealing just how bad low blood flow can be, he explained that it is the "number one brain-imaging predictor of Alzheimer's Disease”.

He continued: "It's the commonest drug, it is addictive. I imply just a little bit is okay, however greater than just a little bit is just not superb.

He stated: "It blocks adenosine, the chemical that tells you to go to sleep, and so many of my patients stop [drinking coffee] and uniformly tell me they feel better."
