Eating Fruit Is Really BAD For Your Brain

Most of us were raised to believe that an apple a day keeps the doctor away. Full of fiber, vitamins, antioxidants, and plenty of deliciousness too, fruit seems like an obvious addition for keeping your diet healthy for life. However, part of what makes fruit so delicious is the sweet flavor, which comes from a type of sugar called fructose.

There is no denying that sugar is bad for you, messing with your metabolism, causing blood sugar spikes, damaging your teeth, and of course causing weight gain and other health problems such as diabetes and liver disease. And now, new studies are showing that sugar – even the fruit sugar fructose – can not only contribute to these problems but can damage your brain too. Your brain needs a certain amount of sugar in order to function. But, consume too much of it in the form of sugary snacks, food with simple carbohydrates, or through more than four portions of fruit per day, and there is a risk of it affecting your brain.

The most surprising piece of research is on how fruit affects your brain-derived neurotrophic factor (BDNF), which is a component that helps you learn and form new memories. Sugar lowers this component, meaning you can struggle at puzzles or studying or remembering things. Even more concerning is the increased links between low BDNF factors with depression and even dementia.

What’s more, all sugar is addictive. It prompts your brain to release the ‘reward’ hormone dopamine, which then naturally makes you want more. What’s more, a study from the University of Southern California found that people who consumed fructose experienced more cravings than if they ate foods with glucose. And as with other addictions, withdrawing from sugar can actually cause uncomfortable symptoms, including shaking, anxiousness, and teeth clenching. Therefore, it is important to cut sugar gradually, eliminating the most obvious sourcing, with an aim to eating as little processed then fruit sugars as possible.

Of course, there are more nutritional benefits to eating a piece of fruit over say, a cookie. But, to keep your brain happy and healthy, opt for fruits that are lower in fructose, such as green apples, berries and watermelon.
